Title: Mount for concave tape guide
IPC: G11B15/62
Filed: 1970-03-17
Abstract: 1,261,305. Magnetic tape recorders. AMPEX CORP. 17 March, 1970 [24 March, 1969], No. 12828/70. Heading G5R. In an arrangement for holding a tape 12 against a rotary head drum 16 with two or more heads, a concave guide 18 is mounted so as to be concentric with the drum in the closed position and to be retractable, Fig. 1, to allow lateral loading. Fine positioning is provided to allow the guide to be moved in both vertical and horizontal directions together with axial adjustment. The guide 18 is rotated on shaft 31 by a cam 36 operating through a universal joint 37, 45, Fig. 2, the spring 42 holding the guide in the closed position, the cam being prevented from rotating further due to bearing 47 providing a locking action. Adjustment in the vertical direction is achieved by displacing a double wedge 51, Fig. 3, between fixed bearing pins 52, 53 and guide pins 56, 57 by means of a lever 71. Horizontal adjustment is achieved by rotating cam 121 which causes a lever 122 to operate on a pin 126, thereby moving the guide towards the drum. During recording a solenoid (141) causes a pin 146 to rotate the cam 121 through a constant torque device, while during playback a second solenoid (161) causes the pin to be controlled by a servomechanism.

Patent GB-778409-A (GB)
Title: Improvements relating to column heads for fractionation columns
IPC: B01D5/00
Filed: 1954-05-04
Abstract: <PICT:0778409/III/1> A head for a fractionating column comprises a distillate line and a reflux line joined to one another, a plunger at or near the junction of the two lines, which in its normal position seals the distillate line but is raised at determined intervals to allow the condensate to pass down the distillate line to a receiver, and means for preventing vapours from the column rising up the reflux line.  The column-head shown is attached to the column by joint 10. In operation, vacuum-jacketed limb 11 is provided with a thermometer inserted through socket 15.  A condenser is connected in socket 16 of limb 12.  The condensate flows down limb 12 into limb 13 which divides into distillate line 17 and reflux line 18. The U-bend 21 prevents vapours rising up the reflux line.  A seating 22 is formed in the distillate line; and the end of spring-loaded plunger 24 is shaped to make a spherical joint with seating 22 when cap 27 is fitted into socket 28.  The plunger is raised, and the seal to the distillate-receiver broken, by the action of an electro-magnet upon a piece of soft iron 29 sealed into the top of plunger-stem 25.  The electro-magnet is connected in circuit with an electric-timer incorporating a beam tetrode power valve, which gives an "on" period which can be varied up to 5 seconds, and an "off" period variable up to 60 seconds.  In order to ensure that a representative sample is taken as distillate when the plunger is open, a sloping gallery 30 directs all the condensate over the seal made by the spherical joint. The column-head may be maintained under vacuum.  The purpose of tap 19 is to give a vacuum tight seal in the distillate line since, under certain circumstances, it may be necessary to vent the distillate-receiver whilst retaining the column-head under vacuum. Specification 564,512 is referred to.

Title: Circular knitting machine for stockings
IPC: D04B9/00
Filed: 1957-04-23
Abstract: 864,151. Knitting-machines. SANTONI & C. April 23, 1957 [April 19, 1956], No. 12964/57. Class 74 (2). In a plural feed machine for knitting stockings bearing diagonal lines of held loops, the needle jacks are arranged around the cylinder in a succession of groups, of which one group has a jack more or a jack less than each of the remaining groups; and each jack has at least one intermediate butt, these intermediate butts being located in different positions on the jacks, but jacks in corresponding locations in all groups having intermediate butts in the same positions. A half a of the cylinder may have jacks with single intermediate butts, the other half b having jacks with two intermediate butts; and a jack is omitted or added (as at A<SP>1</SP>) at the boundary between the two types of jack. If a jack with a single intermediate butt is added, that butt has the same position along the jack as the longer butt of the immediately adjacent jack having two intermediate butts; but if the added jack has two intermediate butts, the longer of these butts has the same position along the jack as the single intermediate butt of an immediately adjacent jack. If the machine has an odd number of needles, the number of tricks in the welt dial is a half of one less than the number of needles; and the width of one I of the lands between the welt dial tricks is then one-and-ahalf times the width of each of the other lands. Corresponding to this land there is a pair of needle jacks having lower end butts of equal height.

Title: Circular knitting machine including means for selecting and operating the needles thereof
IPC: D04B15/78
Filed: 1973-03-19
Abstract: 1424411 Knitting machines SEMITEX AG 19 March 1973 [25 March 1972 14 June 1972 2 March 1973] 13129/73 Heading D1C In a circular knitting machine, lamellar electrical conducting members 22 are carried on the rotatable needle cylinder and each co-operates through a selecting device 15 with a needle 5, each member 22 being movable from a rest position to one of two opposite positions to actuate said selecting device 15 to control the raising of the needles by raising means. Needles 5 which are located in non-magnetic cylinder I by parts 6 and springs 7 have a pivoting point 8 near their centres engaged by an end 9' of a flexible spring 9 whose other end is secured to a ring 10 secured to cylinder 1. Cam 14 prevents spring 9 from raising needles except when knitting is to take place. Levers 16, 17 pivoted to partition members 3 integral with cylinder 1 are held in their last assumed position by an omega shaped spring 21 and have upper arms 16', 17' of different lengths with hook members 19 at their upper ends and projections 20 intermediate their length. Between their lower arms 16", 17" is the insulated end 22' of a member 22 pivoted on magnetic armatures 27 whose upper and lower arms 22", 22"' are electrically connected to contacts 30, 34 of cylinder 31 rotating with cylinder 1. Pulses are applied to members 22 by brushes 30', 34' engaging contacts 30, 34 which respectively have applied thereto a "zero" reference voltage and positive or negative pulses according to a pre-set programme. Movement of member 22 in direction F causes hook 19 of lever 16 to engage a hook 11 of needle 5 and prevents it from being raised and movement in direction F' causes hook 19 of lever 17 to engage hook 11 of needle 5 which allows it to reach its middle position. When member 22 is not moved, the needles can be wholly raised by the action of springs 9 under the control of cam 14. In another arrangement Fig. 2, the needle has a member 106 which can engage either of members 107, 107' which engage tracks 109, 109' formed inside and outside respectively of needle carrying cylinder 101. Member 122 moves needle 105 sideways to engage members 107, 107' when so selected. The tracks may alternatively be one above the other on the same side.-Members 222 may be mechanically actuated, Fig. 9, engaging slots 224 in members 223 which carry butts 225 which co-operate with sliding shoes.

Title: Method and apparatus for identifying characters printed on a document which cannot be machine read
IPC: G06K5/00
Filed: 1976-04-01
Abstract: 1512871 Identifying characters which cannot be machine read BURROUGHS CORP 1 April 1976 [1 May 1975] 13174/76 Heading G4R Characters on a document, such as a cheque, which cannot be identified during machine reading are marked by a printer to enable identification by an operator. Documents 25 are driven at a predetermined speed through guides 27, 27<SP>1</SP> to a read head 31. If a character cannot be identified a signal is supplied on line 35 to a Can't Read Decoder 37 which supplies a signal to a delay circuit 47. The delay of circuit 47 is arranged such that the character that could not be identified is moved to a predetermined position relative to a dot printer 43 when a print signal is fed to the printer. The delay 47 feeds a signal to a gate control circuit 63 which operates a gate to deflect the marked document through a view station 75 so that an operator can see and identify the marked character using a keyboard 83. The document is then returned to the path, connecting the printer and a re-encoding station, that correctly identified documents follow.

Title: Improvements in seals for shafts
IPC: F16J15/38
Filed: 1944-07-11
Abstract: 582,782. Stuffing-box substitutes. FITZPATRICK, H. D. (Chicago Seal Co., Inc.). July 11, 1944, No. 13232. [Class 122 (v)] A shaft sealing device comprises a washer having in one face a recess containing a gasket 22 engaged by a stationary abutment 15, and on or near its other face a sealing face cooperating with a similar face on a spring pressed sleeve 28, the opposite end of which projects through a sealing element 32 carried by a socket 29 secured to the shaft whereby limited movement of the sleeve is permitted.

In a modification the sealing face is formed on a separate bearing member seated on one face of a gasket carried by the ring 18 the opposite face of which bears on the stationary abutment.
Patent GB-567676-A (GB)
Title: Improvements in or relating to clutch mechanism
IPC: F16D43/02
Filed: 1942-09-19
Abstract: 567,676. Friction clutches. WOLFF, O. E. Sept. 19, 1942, No. 13252. Convention date, Jan. 13, 1942. [Class 80 (ii)] [Also in Group XXXIV] In a friction clutch the driving and driven members are held in unlubricated static frictional contact whenever there is no relative motion thereof, or whenever the torque transmitted is less than a predetermined torque, and are sub-- stantially completely disengaged with continuous films of lubricant between their normally contacting surfaces whenever there -is relative motion, or whenever the torque reaches a predetermined value. As shown a plate 38, Fig. 1, on a driving shaft 32 is spring- urged towards a plate 60 on a driven shaft 36 and has friction pads 44 pivoted thereto. The housing 52 is partially filled with lubricant. When driving takes place there is no lubricant between the pads 44 and the plate 60, Fig. 4, but should relative motion or slip occur the pads 44 tilt and an oil film 68, Fig. 3, is built up and the clutch is disengaged. Re-engagement is obtained by bringing the plates 38, 60 to the same speed. In a modification the pads 85, Fig. 5, are supported by centrifugal weights 75 carried by arms 74 on the driving shaft 70, and bear on a drum 90 fixed to the driven shaft. Springs 80 also urge the weights radially outwardly. Thus the torque that can be transmitted is increased with the speed of rotation. The pads may be integral with the weights and may be chamfered at the leading edges. In another modification three sets of centrifugal weights 312, 314, Figs. 24, 25, are pivoted to arms 310 on the driving shaft 300, the pads 320 being carried by springs 318 on the weights. Movement of the weights under centrifugal force is limited by abutments 324, 325, some of the weights being permitted more movement than the others. The pads 320 engage a drum carried by the driven shaft 302. In another modification in which the clutch disengages when the speed exceeds a predetermined value, the pads 210, Fig. 19, engage the outside of a drum 204 on the driven shaft and are carried. by stems 206 radially slidable in a drum 198 on the driving shaft. Springs 216 urge the pads towards the drum 204. In another modification the pads 236, Fig. 20, are integral with centrifugal weights 232 slidingly carried by arms 230 on a casing 228 fixed to the driving shaft. Pins 237 in the casing carry gears 238 which mesh with a gear 225 on the driven shaft. Thus when relative motion occurs between the driving and driven shafts the gears act as oil pumps and oil passes through pipings 240 and ducts 244 to the engaging surfaces.

IPC: H02J3/26
Abstract: 133,970. Metropolitan-Vickers Electrical Co., (Assignees of Fortescue, C. le G.). Oct. 17, 1918, [Convention date]. Phase, changing; systems for conversion, employing rotary converters.-In a polyphase electric supply system wherein the electro-motive forces in the phases become unbalanced, and arc resolvable into a major balanced component and a minor balanced component of the opposite phase sequence, in order to allow the major component only to act on the load, the minor component is suppressed by an auxiliary machine 6, with primary windings 7, 8, 9 independently connected in series with the phases. The secondary 10 is run at a speed in synchronism with the minor component, the machine acting as an impedance thereto. As shown, the polyphase current is obtained from a rotary converter of the induction type, the auxiliary machine being of similar type, the two rotors being on the same shaft. Both machines may be of the synchronous type. The rotor 10 may run independently, the machine floating on the system, or it may be driven by a motor. The primary may rotate instead of the secondary. If currents of undesired frequency are to be suppressed the pole number or the speed of the auxiliary machine is adjusted. so that it is in synchronism with the undesired frequency. An auxiliary machine as described can be used between a single phase load and a polyphase supply system to prevent unbalance of the supply system. Specification 22914/14 is referred to.

Title: Improvements in or relating to lap-forming apparatus in textile machines
IPC: B65D5/02
Filed: 1951-06-06
Abstract: 693,264. Lap-forming apparatus. AKT.- GES. J. J. RIETER & CIE. June 6, 1951 [June 9, 1950], No. 13458/51. Class 120(i) In lap-forming apparatus in which a lap tube is set between two rotatable . lateral side discs, each disc has, on the side adjacent the lap tube, a trunnion for engagement with the bore of the lap tube, and said discs are axially movable in their bearings and each carry a piston subject to the action of pressure fluid for effecting engagement or disengagement of the disc with the lap tube. As shown, a lap tube 6 is engaged by the trunnions 8 of side discs 7, the axles 9 of which are axially movable in bearings 10 and carry pistons 12 movable in bores 13 of pressure heads 11 in which bearings 10 are mounted. Heads 11 are slidable vertically in guide slots 2 of the machine frame and are connected by nested tubes 14, 15, to pistons 17 movable in pressure cylinders 16. Ducts 18, 20, tubes 14, 15, and apertures 19 in tube 15 connect the two sides of pistons 12 to the two sides of pistons 17. Compressed air is supplied to cylinders 16 via a check valve 26, a tank 27, a pipe 28 and a servocylinder 21, the piston 22 of which can occupy an upper, an intermediate or a lower position in accordance with the position, a, b or c of a pedal 25. To start the machine, pedal 25 is raised to position c. Compressed air then flows through pipes 30, 31, to the lower side of pistons 17 and thence to the inner side of pistons 12. Heads 11 are thus raised and discs 7 are moved apart permitting the old tube 6 to be removed and a new tube to be centred between the discs. Pedal 25 is then moved to position b, in which compressed air is supplied to the top side of pistons 17 and the outer side of pistons 12, while escape of air from the lower side of pistons 17 is prevented. Heads 11 thus remain stationary while discs 7 are forced towards each other to clamp the tube 6. Pedal 25 is then moved to position a wherein escape of air from the lower side of pistons 17 is permitted ; heads 11 and tube 6 drop, quickly at first but slowly towards the end of the movement when pistons 17 close air escape pipe 31 and air has to escape through pipe 30 and a flow-restricting valve 33. During winding of the lap, pistons 17 gradually rise, compressing the air trapped by check valve 26 in the system comprising cylinders 16, 21 and tank 27.
