D., 94, Hope Street, Glasgow.- (Maatschappij van Berkel's Patent Naamlooze Vennootschap, (formerly Naamlooze Vennootschap Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen), and BERKEL, C. F. M. VAN., 33, Boezemsingel, Rotterdam, Holland. July 27, 1932, No. 21158. [Class 28 (ii).] A slicing-machine has a circular knife 3, a reciprocating carriage arranged both for pushpull and mechanical operation, a gauge plate 9, slice-feed mechanism 14-17, and means interconnecting the slice-feed mechanism and the plate 9 for simultaneously adjusting the setting of both. The machine may be motor-driven either by a motor 32 engaged frictionally with the handwheel 29, or alternatively as shown in dotted lines, by a motor 38 engaged frictionally with a handwheel 35 on the cross shaft 21. A pneumatic tyre may be provided on the wheel 29, or 35, to be engaged by the motor pulley. The gauge plate 9 is carried by bars 10, 11 guided in brackets 12a, 12b, 13a, 13b, and the guide 13b is screw threaded to engage a screwed part of the bar 11. An extension of the bar 11 has a feather and groove connection with the rotatable slice-thickness adjusting member 14 which also regulates the position of the abutment 15 for actuating the feed screw mechanism 16, 17. The mechanical means for reciprocating the carriage 4 comprises the usual connecting rod 27 which has one end pivoted to an oscillating link 40. The pivot 28 is connected to or released from the carriage 4 by a member 39. Alternatively, the connecting rod may be guided in a longitudinal slideway in the carriage, or there may be two cranks, one loose and the other fast, which are arranged to be clutched together, or there may be a spring or other clutch connection between the crank and the crankshaft or between the crankshaft and its driving gearwheel. When the carriage is mechanically reciprocated the gauge plate 9 may be used only for initial positioning of meat, the plate being moved to an inoperative position during the slicing. The substance engager may be a meat table and clamp 7, 8, but a substance pusher with a spiked face may be used. Alternatively, the clamp 8 may be provided as part of a combination clamp and pusher. When the machine is used with a stationary carriage, the substance engager 7, 8 may be removed from the machine, and the substance moved to-and-fro past the knife, over the stationary carriage.

Title: Improvements in machines comprising a rotary mixing or strirring drum
Inventor: UPHAM GEORGE
IPC: B28C7/08
Filed: 1967-05-08
Abstract: 1,162,909. Mixing machines. AZIMUTFRANCE S.A. 8 May, 1967 [10 May, 1966], No. 21245/67. Heading B1C. [Also in Division B8] A mixing machine, e.g. a mobile concrete mixer, has a rotating drum 1 which can be coupled to a winch 16 to raise a skip 7 to load the drum. The winch is driven by a belt drive from a ring 43 mounted on four rollers 41, spaced around its periphery, in a frame 23 which is pivoted at 28 so that the ring can be engaged with and disengaged from the drum. The driving engagement between the drum and ring is by friction or dogs, and the belt is tensioned to drive the winch by a pulley on a weighted or spring loaded arm (52, Fig. 2, not shown). The skip 7 is hauled up rails 8 by a cable 15 attached to the winch, and the drive is disconnected by a nipple 71 on the cable engaging a yoke 72 to lift the pulley arm (52). This arm is supported by a telescopic strut with a cam-operated lock, arranged so that succesive lifting operations on the bar alternately release and engage the lock. The bar may be lifted for this purpose by an operator by a cable 55 attached to a tensioning reel on a handle 12 of the skip. The handle is used to guide the skip through the material to be lifted and then onto the rails 8, and finally to tip the material into the drum. The winch may alternatively be driven by chain or gear transmission, or may be mounted directly on the ring 43, the drive then being disengageable only by pivoting the frame 23.

Title: Device for cutting sheet material
IPC: B26F1/38
Filed: 1971-04-19
Abstract: 1337862 Cutting apparatus GERBER GARMENT TECHNOLOGY Inc 19 April 1971 [31 July 1970] 21255/71 Heading B4B An apparatus for cutting sheet material, e.g. fabric layups comprises a cutting head 18 movable longitudinally and transversely over a supporting surface 12 and provided with a cutting blade 20 having an end movable within a slot 52 formed in a member 54 which is movable in unison with the cutting head. The cutting head 18 is mounted for transverse movement ona carriage 28 via a guide rail 24 and a feed screw 26 rotated by a motor 36; the carriage is moved longitudinally of the surface 12 by a motor 38 via a rack-and-pinion drive 30, 32. The member 54 is secured to the carriage for movement therewith and may be provided with holes 72, 74 through which air under pressure can be supplied thereby facilitating the movement of the material over the surface 12. In order to control the movement of the lower end of the blade 20, the latter is guided in a sheath 46 rotatable by mechanism in the head 18 and formed with an enlarged portion 48, Fig. 3, rotatable in a guide block 50. The block is slidable in the slot 52 and is moved in unison with the cutting head 18 by means of a cable mechanism 56, 64 connected to the head and the block. In a modification, in order to allow the cutting blade to be withdrawn completely from the material, the cutting head (102), Figs. 8 and 9 (not shown), is raised and lowered by a rack-and-pinion device (105, 107). In normal use the end of the blade guide sheath (106) is located in a bush (110) slidable in a transverse slot (109) formed in the member (108). In order that the movements of the bush should follow those of the sheath the latter two parts are connected by a cable-and-pulley mechanism, Fig. 11 (not shown). In a further modification, the sliding block 50 or bush (110) and the associated mechanism may be dispensed with and the slot in the member 54, (108) filled with a penetrable material, e.g. foamed plastics, (116), Figs. 12, 13 (not shown), a self-healing material, granular material, e.g. sawdust, or a bed of bristles, Figs. 14, 15 (not shown). Alternatively, the material may be placed on a stiff cardboard sheet which prevents the material being pressed into an empty slot.

Title: Improvements in and relating to hydraulically-controlled variable-speed torque-transmission apparatus
IPC: F16D25/00
Filed: 1935-07-27
Abstract: 454,984. Variable - speed gearing. HARTLEY, J. W., and RODGERS, W. G., Kearsley Chambers, Shelton Old Road, Stokeon-Trent. July 27, 1935, No. 21366. [Class 80 (ii)] A variable-speed gear comprises a driving- shaft 17 and a driven shaft 18 which are connected by gearing 15, 24, 25, 27 and 16. The gears 15 and 16 are secured to the shafts 17 and 18 respectively and the gears 24 and 25 are secured to a sleeve 26 which is rotatably mounted upon a shaft 23 secured to crank arms 21, 22, which are freely mounted upon the respective shafts 17 and 18 so that the gears 24, 25 act as planets and can rotate with the crank arms 21, 22 about the axis of the shafts 17, 18. The speed of rotation of this planetary system is controlled, to regulate the speed of the driven shaft 18, by liquid displacement in cylinders 10, the pistons 11 of which are driven by connecting-rods 12 coupled to the shaft 23, the liquid being displaced from one cylinder to the other through a pipe 13 under the control of a valve 14. The gear 27 is an idler causing the gears 25 and 16 to rotate in the same direction and the shafts 17 and 18 therefore in opposite directions. Alternatively, the gears 25 and 16 may be in the form of sprockets and connected by a chain so that the idler 27 is not required. The valve 14 may be controlled manually or automatically in accordance with the speed of the driving shaft. When applied to a vehicle the mechanism takes the place of a clutch, the control valve 14 being open and offering no resistance to the movement of the pistons 11 and the planet system when the engine is idling and the vehicle is stationary. If the accelerator pedal is depressed, the speed of the engine and the driving shaft of the gear increases, the valve 14 is closed gradually and the driven shaft is gradually speeded up. The fluid pressure generated by the pistons 11 may be utilized to move spring-loaded brakes to the off position as the vehicle commences to move.

Filed: 1943-12-24
Abstract: 574,043. Gyroscopic apparatus. OLSHEVSKY, D. E. Dec. 24, 1943, No. 21670. [Class 97 (iii)] A direction indicator for aircraft &c. comprises an annular compass card mounted on a gyroscope having four rows of complete markings each row being displaced laterally by 90 degrees with respect to an adjacent row, a vertically movable mask to exclude from view all but one 90-degrees arc of maskings and a lubber-line index for setting by the pilot to the selected heading. As shown in connection with air-driven directional gyroscope, the annular compass card 50 is attached to the vertical gimbal 15 and bears four sets of complete compass markings, displaced relatively by 90 degrees intervals. A slotted masking shield 52 may be raised and lowered by an external knob to display a 90-degrees arc of the selected row of compass markings. The lubber line 61 secured to a gear segment 62 may be adjusted by a knob 69 to the exact setting required on the selected compass arc. In a modification, the four sets of compass markings are carried on an'endless band in gear-driven connection with the vertical gimbal of the gyroscope, this arrangement causing the band to move in the same direction as the landmarks on the horizon when the aircraft deviates.
Patent GB-1545117-A (GB)
Title: Comparison apparatus eg for use in character recognition
IPC: G10L15/00
Filed: 1976-05-25
Abstract: A succession of signals forming the components of an input vector are compared simultaneously with a plurality of reference vectors as the components of the reference vectors are read out in time parallel fashion from a plurality of registers. The comparisons are effected component by component by a plurality of comparators, one per reference vector. The outputs of the comparators are applied to respective integrators or accumulators. At the completion of the comparisons, that integrator or accumulator which stores an extreme value in a predetermined sense indicates the reference vector with which the input vector matches most closely. The vectors may represent characters or samples of waveforms such as speech waveforms, for example, and the invention may be applied to optical character recognition, speed recognition and so on. The apparatus can be implemented from standard, off-the-shelf solid state circuits and avoids the need for purpose built circuitry, such as fusible resistor matrix read-only memories and, therefore, avoids the additional expense and lack of flexibility of such circuitry.

Filed: 1967-05-10
Abstract: 1,191,731. Photo-electric dosimeter readout. COMMISSARIAT A L'ENERGIE ATOMIQUE. May.10, 1967 [May. 11, 1966], No.21732/67. Heading G1A. A method of reading a dosimeter of the kind comprising a film, which is coated with a number of photographic emulsions of different sensitivities and which, during exposure to ionizing radiation to be evaluated, is located behind a number of filters of different known absorption coefficients, said filters defining different fields or areas on the emulsions, the method comprising, for each emulsion, measuring the illumination values of a photometer by light from each area of the film (i.e. due to the optical density of the developed film) and, for each area, multiplying the inverses of the illumination value by a factor dependent on the absorption coefficients of a reference filter which covered a reference area of the film during exposure and of the filter which covered the area under consideration; to obtain a modified value which is used to read the radiation dose from a stored calibration curve for the reference area. In the arrangement shown in Fig. 4 for examining a film having three emulsions exposed through seven filters, a photometer head 1 picks up light affected by the optical density of a developed exposed film and the signal is, in circuit 2, inverted and passed through a first integrator, a threshold circuit and a second integrator, all detailed in Fig. 6 (not shown). Initially, light from a reference area of the film is considered and the calibration curves of inverse illumination valves (photometer signals) against dose, stored in comparator devices 6 for each of the three emulsions. Then reading of the doses received by one emulsion commences, the appropriate channel 4, 5, 6 being switched into circuit. In device 4, the effect of background fogging is removed from the signal. In device 5, the signal is multiplied by the above-mentioned factor so that the modified photometer signal may be compared with the stored reference calibration curve to read out the dose. There may be facility in the device 6 for compensating for non-linearity of the calibration curve.
