Abstract: 1,022,623. Masted lift trucks. CONVEYANCER FORK TRUCKS Ltd. June 1, 1964 [March 14, 1963], No. 10145/63. Heading B8H. [Also in Division B7] An operator's control cockpit of a masted lift truck is rotatable about a vertical axis on a horizontal arm which is pivoted about a vertical axis on the truck frame or on a fixed mast section whereby the cockpit can be swung from one side of the truck to the other. As shown in Fig. 1, the cockpit 20 is rotatably suspended from an arm 19 pivoted on a cranked arm 15 which is pivotably mounted between plates 13, 14 on the fixed mast section 12. An arm 23, 24 rotatably secured to the base 21 of the cockpit is provided with rollers 25 running on a guide track 26 on the truck frame. A telescopic strut 33, 34 is pivoted at 35 on plate 14 and the section 34 is constrained at 36 to follow a cam track in plate and is pivoted at 38 to a lever 39 which is connected through a clutch 41 to a spindle 40 suspending the cockpit from the arm 19. When the clutch 41 is disengaged, by means of a control cable 42 connected to a foot pedal 28 and to a steering wheel 29, the cockpit can be rotated in its mounting on the arm 19 by operation of an electric motor 30, mounted on the arm 23 and driving a pinion 32 meshing with a gear-wheel 31 secured to the cockpit. The arm 15 is rotated to swing the cockpit to one side of the truck by rotating an arm 17A, which is pivoted to a bracket 16 on the mast section 12 and which is connected to the arm 15 by a post 18, by means of a rack and pinion mechanism 52, 53. With the clutch 41 engaged, the telescopic strut 33, 34 and cam track 37 cause the cockpit to remain facing in the same direction, during rotation of the arm 15. The steering wheel 29 is connected through a clutch and bevel gearing 45, shaft 46 universally jointed at 47 to a shaft 48, bevel gearing 49, and a telescopic shaft 50 to the hydraulic motor 44 of a hydraulic servo-mechanism 43 controlling the steering of rear wheels 7. The clutch at 45 is disengaged by pulling the steering wheel from position A to position B, which movement also releases clutch 41, disengages the truck transmission and applies the brakes. The forks 11 are connected to the lifting carriage 10 by a reach mechanism such as that described in U.S.A. Specification 2,752,058. In the embodiment shown in Fig. 3, the cockpit 68 is rotatably mounted on a spindle 68A at one end of an arm 69 which is rotatably mounted at its other end on the truck frame. The arm 69 is rotated by a hydraulically actuated rack and pinion mechanism. A chain sprocket is mounted to rotate with the arm 69 and is coupled by a chain to a similar sprocket connected to the spindle 68A by a clutch whereby, when the clutch is engaged, rotation of the arm 69 causes converse rotation of the cockpit 68. An electric motor may be provided to rotate the cockpit with respect to the arm 69 when the clutch is disengaged.

Title: Improvements in or relating to an arrangement and a method for translating graphic characters
Inventor: NEWTON GEORGE CHARLES
IPC: G06V10/10
Filed: 1957-03-29
Abstract: 817,921. Character recognition. ELECTRIC & MUSICAL INDUSTRIES Lttl. March 28, 1958 [March 29, 1957], No. 10292/57. Class 106 (1). A legible character is recognized by comparing signals derived from sensing it with signals derived from sensing in turn a plurality of master characters, the comparing circuit being adapted to produce an output when substantial identity is established. The characters are printed or typed on a sheet passing over the roller 1, Fig. 1, of a typewriter carriage which moves in steps to present each character in turn at the sensing position. A spot of light in cathode-ray tube 2 moves in a raster of 12 to 20 lines, and is concentrated by lens 3 on to the character, the reflected light being received by photocell 5. A partial reflector 8 passes a replica of the scanning spot on to the surface of a transparent hollow drum 6 or disc bearing the master characters as shown in Fig. 2, transmitted light being received by photo-cell 11. The drum rotates once for each recognition operation each master character being scanned and the signal derived being compared with that derived from the character on the sheet which is scanned several times. Means are provided for aligning the scanning beam accurately on the character. For this purpose opaque sections 9 on drum 6 are scanned and the beginning of the derived waveform is compared with the beginning of that from the character to be recognized. The difference is used to alter the beam position and tilt mirror 8 correspondingly so that the necessary adjustment is made. Alternatively two cathode-ray tubes may be used. The characters on drum 6 are provided to compensate for the effect of the rotation of the drum during the scanning.

Patent GB-105654-A (GB)
IPC: C02F3/20
Abstract: 105,654. Caink, T. May 20, 1916. Aerating.-In tanks for the aeration of sewage treated with activated sludge, an air-tight roof D prevents the air injected by diffusers C, N from escaping directly to the atmosphere and deflects it horizontally to an exit M, whereby circulation of the sewage in the tank is set up to effect more efficient aeration. Sewage entering by the inlet B follows the course of the arrows, and in passing through the contracting passage F between a baffle E and the partition J between the tank and the next of the series acquires an increased velocity at which it sweeps over and between the raised floors H, K, preventing sludge from settling thereon. According to a modification, the sewage flows through parallel series of tanks, the roofs of which deflect the air currents across the series of tanks at right-angles to the direction in which the sewage would flow if not influenced by the air, and baffles are so arranged that the resultant flow of sewage is in the nature of a spiral motion.

Title: Improvements in method of and apparatus for sealing containers in vacuo
IPC: B67B3/24
Filed: 1921-04-11
Abstract: 181,182. Dehn, F. B., (Perfect Vacuum Canning Co.). April 11, 1921. Preserving food; preserving liquids.-Apparatus for sealing filled cans or like containers in vacuo is provided with rotary air-lock devices for feed and discharge so that the cans can be continuously fed into the apparatus and discharged therefrom. The filled containers are placed on a feed-table 6 where they are engaged by lugs 3 on a rotating disc 2 and carried between guides 8, 9 to a star-wheel 10, which delivers them to pockets 13 in a rotating cylinder 12. The cylinder 12 rotates in contact with cheeks forming the sides of an inlet port to the vacuum-chamber, and is loosely mounted on its support, so as to be always pressed against these cheeks by the atmosphere. When the containers arrive opposite the port they are thrust out of the pockets 13 by cam-actuated fingers 14 on to a chain 20 provided with lugs which engage the containers and carry them past appliances for supplying and sealing on covers to guides 23 which deliver them to the outlet device 24. This is similar to the inlet device and delivers the containers to a discharge table 25. The covers are supplied from a magazine shown in Figs. 5 and 7. It consists of two chambers 38, 39 each fitted with an air-tight door through which a pile of covers can be introduced, and arranged to rotate on a bolt 42 so that either chamber can be brought over an opening 43 in the vacuum chamber. The piles of covers are held in position by sliding bolts 50, Fig. 7, which can be retracted to release the covers bv means of rods 51, the lower ends of which engage with the bolts, while the upper ends are provided with pinions 52 engaging with a wheel 53 which can be rotated by a handle 54.

Abstract: 564,256. Measuring continuous lengths. ABBEY, A. (Bliss Co., E. W.). July 29, 1942, No. 10622. [Class 42 (ii)] [Also in Group XXII] In a machine for operating on sheet material S, the feed rollers 10, 11 are stopped, after the desired length has been fed, by means of a switch 57 operated by a cam 55 to which a torque is applied by power, but rotation only occurs when a roller 15 in contact with the work rotates. The roller 15 is pressed by a spring on to the work and its rotation is transmitted by bevel gearing shaft 78, worm and wheel 80, and overload friction clutch 86, Fig. 4, to the outer member 32 of a roller ratchet clutch, the inner member 30 being integral with a dial 18, the cam 55 and a pinion 24, to which a clockwise torque is applied by a rack 46 and a piston 45, Fig. 3, acted on by pressure fluid from a pipe 49. The dial is set, to give the feed desired, by adjusting a stop 50 and admitting fluid by a pipe 48 to the cylinder 40, the clutch member 30 rotating freely in the member 32. When, however, the clockwise torque is applied, the clutch 30, 32 and non-reversible worm drive 80 prevent the dial from rotating until the sheet is fed. Before the switch 57 is operated, the cam 55 operates a switch 56 which effects a slowing down of the feed.

Title: Improvements in pleat-forming mechanism for sewing machines
IPC: D05B35/08
Filed: 1931-04-11
Abstract: 368,555. Sewing-machines. SINGER MANUFACTURING CO., Ltd., Singer, Clydebank, CORRALL, H., St. Alban, Helensburgh, Dumbartonshire, and HEGGIE, J., 7, Drumry Road, Clydebank. April 11, 1931, No. 10702. [Class 112.] A spring-urged pleat-forming blade of a sewing-machine for use in pleating hat linings, shirt backs and like articles is pivotally supported by an arm on a rock shaft and is reciprocated thereby in the line of feed above the work in advance of the stitching point by a rotary cam, the blade being tilted clear of the work in its return stroke by means controlled by another cam rotating with the first cam. The pleat-forming blade 1 is carried by a bifurcated bracket 21 pivoted on a pin 22 in the lower end of an arm 3 secured to a rock shaft 4 adapted to be rocked, by a cam 5 mounted on a rotary shaft 6 driven through gearing, from a main shaft. The rock shaft 4 is connected to the cam 5 through a pair of slotted levers 11, 16 connected together by a slide block 12 adapted to be clamped in position by a wing nut 19 to control the amount of oscillating movement imparted to the blade 1 while the machine is running. The block 12 may carry an index member 20 to indicate the setting of the pleat-forming mechanism. The blade 1 is held down to the work by a spring 2 and is maintained there during the forward or operative stroke of the blade 1 by one of a pair of cams 8, 9 also mounted on the shaft 6 and engaging one end 28 of a lever pivoted at 29, the other end of which is connected by a link 25 to an arm 23 secured to an overhung portion of the pin 22. On the return stroke of the blade 1 both cams 8, 9 are clear of the lever 28 and the arm 23 is raised by a tension spring 25<1> to engage the spring 2 and free the blade 1. A light spring serves to tilt the blade from the work.

Abstract: 982, 622. Electric selective signalling. R. & R. RESEARCH Ltd. March 13, 1963 [March 21, 1962], No. 10775/62. Heading G4H. In a television or like monitoring system the separate sets 15, Fig. 1, are connected by lines 7 to a central station, and each has a relay 25 responding to the switching on of the set to produce a current pulse on lines 7 having a predetermined time integral, the pulses appearing across resistor 13 at the central station are then integrated at 14 to provide a count of the number of sets switched on in given period. Simultaneous or overlapping pulses are integrated to give an accurate count. The relay 25 is operated by contact 21 when the button 20 is operated to switch on the set to apply capacitor 22 across the coil. Contacts 26 then remain closed until the capictor 22 reaches a certain state of discharge, a period of about two seconds. A D.C. source 11 causes current to flow through lines 7 and resistor 13 when the contact 26 closes, the pulses being shown in Fig. 2. Pulses at times tl, t2 are separate but those at t3, t4 and t5 overlap. The integrator gives a count of three for the overlapping pulses at t3-t5. The integrator may consist of an oscillator, the frequency of which is governed by the voltage appearing across resistor 14. The output of the oscillator is applied with a standard frequency to the hetrodyne circuit, the output of which is a frequency proportional to the input voltage. The cycles are converted to pulses and counted. The fixed period pulses may be provided by a cam contact at each set position controlled by a synchronous motor started when the set is switched on. Alternatively a capacitor at each set position is thrown across the line when the set is switched on, providing coincident, separate or overlapping pulses as in Fig. 6. The time integral of each pulse is the same so that the integrator again produces an accurate count of the sets switched on.

Title: Improvements in the manufacture and production of lubricants
Filed: 1937-04-15
Abstract: Oils for lubricants or for additions to other lubricating oils are manufactured by condensing aliphatic hydrocarbons of m.w. at least 170 and containing at least 13,5 parts of H for each 100 parts of C, or derivatives of such hydrocarbons containing O, in the presence of a small amount of isocyclic compounds containing at least three rings, and of a large amount of cyclic compounds containing one or two rings.  The aliphatic hydrocarbons preferably consist wholly or mainly of paraffin wax, which in turn is preferably pre-halogenated. Preferably 0,1-5 per cent of the isocyclic compounds and 5-20 per cent of the cyclic compounds are employed.  In the example, 100 parts of chlorinated paraffin wax containing about 12 per cent of Cl are diluted with 100 parts of lubricating oil or ethylene chloride and condensed with 10 parts of naphthalene and 4 parts of a fraction boiling from 330-380 DEG  C. of a destructive hydrogenation product from mineral coal, the condensation being effected in the presence of 6 parts of AlCl3 and 5 parts of ZnO.  The reaction product is freed from insoluble substances by centrifuge and from the diluent by distillation.  There is obtained, 30 parts of unchanged wax and light lubricating oil, a distillation residue of 70 parts of an oil of viscosity 60 DEG  Engler at 100 DEG  C.  If 0,05 per cent of the oil be added to a machine oil obtained from German mineral oil, it lowers the settling point from -3 to -20 DEG  C.  Specifications 349,071, 407,379, and 410,833 are referred to.
