Title: Improved process and apparatus for the sterilisation of bottles
IPC: A61L2/00
Filed: 1934-07-21
Abstract: 441,499. Bottle-sterilizing apparatus. SCHLOR, F., Menziken, Switzerland. July 21, 1934, No. 21364. Convention date, July 21, 1933. Addition to 407,672. [Class 138 (i)] In a modification of the process described and claimed in the parent Specification, the bottles sterilized by hot steam are brought to a lower temperature after leaving the steam chamber by being cooled in stages by sterile water at different temperatures. In the construction shown; the bottles carried in baskets 5 on an endless conveyer pass upwardly through zones 3a, 3b, 3c in which they are sterilized by steam, the temperature of which is hottest in the highest zone 3c. On the downward journey the bottles move into zones 3d, 3e of increasingly cooler steam vapours and in the zone 3e they are further cooled by water sprays. The sprayer 15 is supplied with cold water which may be cooled by being passed over cold brine. The water from the sprayer 15 is collected in a vessel 19 and fed by a pump 22 through pipe 27 to sprayer 14. The pipe 27 is provided with a filter 23. The water from the sprayer 14 is similarly collected and pumped to the sprayer 13, which in turn supplies water to the sprayer 12. The water falling from the sprayers 12 ... 15 is thus at temperatures decreasing towards the zone 3f. The temperature of the sprayers may be adjusted by steam supplied through nozzles 24. Sterile cold fresh air may be blown through an opening 38 and removed through an opening 39.

Title: Improvements in or relating to fuel injection pumps
IPC: F02M41/08
Filed: 1956-07-10
Abstract: 810,227. Fuel injection pumps. MONOCAM Ltd., FRIEDLANDER, W., and MIRACKI, Z. S. July 5, 1957 [July 10, 1956], 21386/56. Class 102(1). In a fuel injection pump in which fuel is supplied to a spill chamber at the end of each piston stroke, the timing of injection is controlled by the pressure in the spill chamber. A fuel injection pump comprises a series of axial arranged pistons 11 working in cylinders 12 having inlet and outlet ports 13 and 14 respectively the injection being terminated by a spill port 41, connected by a longitudinal paesageway in the piston to the pumping chamber, controlled by a sleeve 43. The sleeves 43 are connected to a member 44 which is urged in an upward direction by a spring 45 bearing against an end 48 of the member 44 and member 46 secured to an adjustable rod 47. The pistons 11 are actuated by a cam 23 provided with a hollow shaft 24 which is operatively connected to the drive shaft 25 by helical splines 28. The shaft 25 is axially movable and urged inwardly of the pump by a spring 31 and abuts against a piston member 35. In operation liquid from the spill port 41 enters the spill chamber 38 and flows through passage 51 and an aperture 52, formed between the rod 46 and the member 44, to chamber 49 connected to the feed circuit of the pump. As the speed of the pump increases so will the pressure in the spill chamber 38 and this acts on member 44 against the spring 45 to vary the position of the sleeves 43. The governed speed of the engine is thus determined by the position of the rod 47, through member 46 fixed to the rod, which adjusts the force of spring 45. The pressure in the spill chamber also acts on the piston 35, through passage 37, and when this overcomes the force of the spring 31 the drive shaft 25 moves axially and through the helical splines 28 causes angular displacement between the shaft and cam to vary the timing of the begininning and end of the injection period.

Title: Improvements in electronic digital computing machines
Inventor: WILLIAMS FREDERIC CALLAND
IPC: G11C11/23
Filed: 1949-08-17
Abstract: 734,482. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 2 1950 [Aug. 17, 1949], No. 21441/49. Class 106 (1). An electronic digital computing-machine of the type employing electrostatic digital storage devices, is operated upon a fundamental rhythm of three beats in a bar by arranging that each instruction word when read out from storage during a first action beat is held upon an instruction staticisor which controls addressselection in the main store before the commencement of a digit-handling operation in the beat which follows such first action beat and which is, itself, also an action beat. As compared with the operation of the four-beat machine described in Specification 731,341, in the present machine the third or scan 2 beat is eliminated by transferring the extracted and temporarily staticised Present Instruction word directly to the main store staticisor MSTR instead of routing it by way of the Control unit. In the first scan beat all the storage devices are regenerated, the existing Control Instruction in the unit CIS has +1 added thereto and is then read out through the instruction gate IG, opened by the Halver-A waveform, to cause setting up of the main store staticisor MSTR. During the next beat the Present Instruction in the main store MS, as selected by the setting of the staticisor MSTR, is read out through the P.I. transfer gate PSG, which is opened by the Instruction-gate waveform, to the P.I. staticisor PSTR. At the end of this beat the main store staticisor MSTR is reset by the MSTR-Reset waveform and, immediately afterwards, within the prevailing Blackout period, the P.I. staticisor PSTR is also reset. As a result of this latter resetting, negative-going pulses are fed from all those sections of the P.I. staticisor which had previously been triggered to the corresponding sections of the main store staticisor, so that the latter is triggered, in the parallel mode, whereby it now carries the setting previously held by the P.I. staticisor. This new P.I. setting determines the address in the main store MS which is concerned with the computing operation and the route or type of operation required, and during the third beat this present instruction is obeyed. In order to cope with a 40-digit number an additional beat may be added. The production of the various waveforms concerned with the beat-tobeat changes necessary throughout the machine to comply with the three-beat or extended fourbeat rhythm, is described. Specifications 645,691, 657,591, 682,156, 705,474, 705,479, 734,071, 734,073, 734,075 and 734,483 also are referred to.

Filed: 1967-05-09
Abstract: 1,179,132. Counting apparatus. ROCKWELL MFG. CO. 9 May, 1967 [9 May, 1966], No. 21525/67. Heading G4D. A meter is adjustable so that either of two tax-rates or no tax can be charged. As applied to a mobile fuel dispenser, knob 26 adjusts shaft 130 before a dispensing operation to a standard tax rate (4%) in which clutch 71, Fig. 3, engages gear 73, a higher tax rate (6%) in which the clutch engages gear 75, or tax-free in which clutch 71 is disengaged and a worm drive 61, 62 is also disengaged by link 134, Fig. 7, pulling link 144 so as to cam bell-crank 172 clockwise about its pivot 69. In tax-free position the drive passes directly along shaft 59 through gears 87, 88, 85 and differential 82 to gross sale indicator and printer 104 and a totalizer 95. In either of the tax rate positions an appropriate percentage is computed by worm drive 61, 62 and selected gear 73 or 75 to be added to the standard price in differential 82 and transmitted through gearing to tax indicator and printer 120 and totalizer 127. When a dispensing operation is complete knob 22 on shaft 190 is oscillated. The first movement effects printing followed by resetting of indicators 104 and 120. The return movement causes nose 206 of cam 196 to swing hammer 214. If knob 26 has been set to tax-free or 6% tax position then pin 202 or 204 will be struck by the hammer to return shaft 130 to its intermediate (4%) position shown in Fig. 7. Cam 186 prevents knob 26 adjusting shaft 130 except when shaft 190 and therefore knob 22 are in home position.

Title: Improvements in and relating to sputter-ion vacuum pumps
IPC: H01J41/16
Filed: 1963-05-29
Abstract: 1,031,426. Sputter ion vacuum pumps. VARIAN ASSOCIATES. May 29, 1963 [June 7, 1962], No. 21548/63. Heading H1D. [Also in Division G3R] Sputter ion vacuum pump apparatus includes a heating element 23 disposed within the pump housing for applying heat to the interior of the pump casing so as to produce outgassing. As shown, the apparatus comprises a main vacuum chamber 11 connected to a fore-pump 12 via a pipe 16 and a valve 18 and to the sputter ion pump 13 via a pipe 14 and a valve 10. During preliminary evacuation, valve 10 is closed and the vacuum chamber is pumped by the forepump, outgassing of the chamber and pipe 14 being achieved by heating coils 31, 33 respectively. The sputter pump is then energized, valve 18 closed and valve 10 opened until a predetermined pressure, e.g. 4À10<SP>-5</SP> mms. of mercury is obtained, whereupon the heating element 23 is energized to outgas the pump housing. The pressure rises, and the element is de-energized at another predetermined prescure, e.g. 5À10<SP>-5</SP> mms., and the pumping continued until the pressure again drops to 4À10<SP>-5</SP> mms.; this cycle of operation is continued until the house is sufficiently outgassed. The cycling may be accompanied manually, or automatically using a current measuring resistor 41 connected to the pump supply, the voltage across which controls a relay 43 connected to the heating element power supply 44. In an alternative embodiment, Fig. 3 (not shown), the heating element is arranged within a tube forming part of the pump housing and extending within the pump, the changing of the element in the event of its failure being greatly facilitated.

Title: Stitch-forming mechanism for sewing machines
IPC: D05B29/06
Filed: 1929-07-13
Abstract: 324,613. Singer Manufacturing Co., (Assignees of Eames, G. M.). Nov. 9, 1928, [Convention date]. Needles, vibrating laterally.-A reciprocating needle-bar is carried in a pivoted frame with means for adjusting the field of lateral vibration and means for determining the path of reciprocation of the needle-bar in a selected field of vibration. The invention is illustrated as applied to a laterally vibrating lock-stitch, rotary hook, embroidering machine. The needle 23 is carried on a needle bar 15 which reciprocates in bearings 16, 17 of a swinging frame 18 pivoted on a pin 19 with an eccentric reduced portion 20. The needle-bar is reciprocated by the main shaft 8 through the linkage 11 - - 14 in the usual way. The frame 18 is vibrated by the rock shaft 78, a cranked part 77 of which engages the frame at 76. The shaft 78 is rocked by the triangular cam 86, secured to the gear 88, through the linkage 84, 82. 81, 80. The pitman 84 has a bifurcated end 85 embracing the cam 86 and has a bifurcated link 94 secured to it by a pin 92 and screw 93. This link is pivoted at 96 to one arm of a double armed lever 97 which is, in turn, pivoted on the pin 98 eccentrically journaled in a bushing 99. The position of the pin 98 is adjusted by turning an arm 108, fixed to the end of the pin, over a segmental plate 101, or by actuating the long arm 110 of the lever 97 by a knee shift through connections 116, 112, 111. When the pivot 96 intersects an imaginary line from the axis of the cam 86 to the pivot of the pitman 84 on the link 82, the shaft 78 will not be rocked and the needle will reciprocate without vibrating. This is the zero position and the reciprocation of the needle-bar may be brought to the vertical by turning the pivot 19 of the frame 18 about its eccentric extension 20. By moving the arm 108 over the segment plate 101 between the stops 104, 106, or by moving the arm 110 by the knee-shift, the position of the fulcrum 96 of the pitman 84 is altered, thus causing the shaft 78 to rock to a corresponding degree to vibrate the needle. The rotation of the looper shaft 71 is accelerated or retarded to a corresponding degree by an arm 117 secured by a ball-joint to the pivot point between the pitman 84 and link 82. This arm actuates a bell-crank lever 118, 121 to move a sleeve 67 forwards or backwards, to move the spiral gear 59 across the corresponding driving gear 60. Presser-bars.-The presser-bar 24 is hollow and has a medium rod 33 with a lower shoulder 35 for securing detachable presser-feet 36, and a clamping screw 34 at the top. Presser-feet. - The presser-feet 36 have the needle slot 37 at the end instead of the side. Work supports.-The throat-plate, which may have a central projection, for eyeletting, or may be flat, for progressive embroidery, fits into a recess in the supporting plate 42 above a hub 40. The hub 40 and the throat plate are secured by the arms 51 of the slide 53 secured to the inspection slide 48.

Filed: 1929-07-15
Abstract: 334,019. Murphy, P. F. July 15, 1929. Affixing labels and like small sheets.-A machine for folding seals around the edges of pamphlets &c. comprises means for feeding a strip of sealing material, such as gummed paper, between a table and a punch which is reciprocated to remove portions of the strip and apply them to the edge of the pamphlets &c. fed intermittently along the table and stopped while the seals are applied thereto. The severed portion of the strip is applied with part projecting beyond the edge of the pamphlet &c. and is folded round the edge as the pamphlet is moved forwardly. The pamphlets &c. are placed by hand upon a conveyer 124, Fig. 1, with their leading edges against projections 128, Fig. 7, thereon and are fed to the table 1. The conveyer is driven from a shaft 28 which is driven through release mechanism operated to disconnect the drive in the absence of a pamphlet. The drive is effected through a motor 11 and reduction gear to a gear 34 freely mounted on the shaft 28. The gear 34 has a spring-influenced detent 35 normally engaging a projection 33 on a disc on the shaft 28. The detent 35 is operated to disconnect the drive by a rod 41 actuated either by a hand-lever 48, or by a lever 51, the lower bent end of which lies in the path of the pamphlets; the absence of the latter permits a downward movement of the rod to operate the detent 35. The member 41 also engages a projection 163 to stop the shaft 28. The strip of paper is led from, and to, a pair of reels detachably mounted on a shaft 81 driven frictionally to wind up the strip from a shaft 93. The shaft 93 is driven through ratchet mechanism operated by a cam on the shaft 28, and carries one of a pair of feed rolls 95 which feed the strip. The latter passes from the loosely-mounted storage reel over guide rollers 106, 109, down to a slot 17 in a hollow shank 16 in which works the punch 5 operated by a lever 20 from a cam on the shaft 28. The punch co-operates with a die 3 and the strip is damped by a spray supplied through an orifice 64 in synchronism with the movement of the punch, the spray being supplied from a receptacle screwed into the orifice 64; air pressure is generated by a pump 69 actuated from the shaft 28 and fitted with a spring valve 70 operated by the piston 73 at the end of its compression stroke. The severed part of the strip constituting the seal is attached to the edge of the pamphlet which is positioned by cam-operated stops 58 projecting through holes in the table. The seal is folded as the pamphlet moves forward by means of a pivoted member 130 which deflects the projecting part of the seal downwards through a slot 133; further movement of the pamphlet folds the seal, and the pamphlet is taken by feed rolls 134, 135 and stacked. 'The folding operation may be omitted and the machine used for applying labels &c., severed from a strip, to other articles at other points than their edges.

Title: Systems for the electrical transmission of angular data
IPC: G05D3/14
Filed: 1944-11-06
Abstract: 601,518. Telecontrol systems. WILLIAMS, R. W., LANGHAM, E. M., ASKEW, J. H., and WRIGHT, C. S. Nov. 6, 1944, No. 21781. [Class 40 (i)] In a system for transmitting angular position of the type employing coarse and fine selsyns at the transmitter and receiver, wherein the output from the coarse or fine receiver selsyn according to the deviation from correspondence feeds an amplifier controlling a servomotor for driving the selsyn rotor to the new position, the coarse receiver rotor is provided with an auxiliary winding at right-angles to the normal winding to remove the ambiguity which may arise if the apparatus is switched on with a 180 degree discrepancy between the indication of the transmitter and receiver. The system is particularly applicable to apparatus where the gearing ratio between coarse and fine selsyns is an even integer, giving a stable state for the fine selsyn system of 180 degrees discrepancy. In the normal position, the rotor coil 10 of fine receiver selsyn, feeds over an attenuating network R6, R7 and contact 8a of relay 8, the amplifier input 9. When the discrepancy between coarse transmitter and receiver exceeds a certain angle, the A.C. potential developed in coarse rotor 4 and fed over transformer T1 to diode rectifier VI, produces a D.C. potential sufficient to cause the normally non-conducting valve V3 to pass anode current and relay 8 to operate, transferring the amplifier input 9 from the fine to the coarse selsyn rotor. If the apparatus should be switched-on with a discrepancy of 180 degrees, the fine receiver rotor 10 would normally be in circuit, since there would be substantially no voltage across coarse rotor 4. With an even gear ratio, the fine selsyn would remain in a stable state, Fig. 1 (not shown). To avoid this ambiguity, an auxiliary coil 5 on the coarse rotor feeds a diode V2 to develop a further D.C. potential in series with that from diode VI. By employing a bias from transformer T2 the D.C. potential developed by winding 5 in the correspondence position is zero, rising to a maximum at 180 degrees. The D.C. bias of valve V3 is chosen so that the relay 8 operates, due to the A.C. voltage from winding 5, over an angle about 180 degrees at least, as large as the ambiguity angle. In a modification, Fig. 3 (not shown), the coarse rotor 4 feeds an amplifier which operates a relay when the input exceeds a certain value to transfer the amplifier input 9 from the fine to the coarse selsyn. The output from auxiliary winding 5 in series with the A.C. bias voltage operates a further relay, near the ambiguity position, to maintain the coarse selsyn connected and fine selsyn disconnected.
