Title: Improvements in or relating to gripping devices for use with meat slicing machines
IPC: B26D7/01
Filed: 1932-12-01
Abstract: 391,717. Slicing-machines. BLICK, E. L. and AUTOMATIC SCALE CO., Ltd., Broadheath, Attrincham, Cheshire. Dec. 1, 1932, No. 33989. [Class 28 (ii).] A last-slice holder of the kind having spikes secured to parallel shafts which are partially rotated, to project the spikes through the face-plate into the meat, is provided with means which, during the working of the machine, automatically moves the spikes into fully projected position if the operator has, inadvertently, left them partially projected. The spikes are usually curved, and if partially projected extend excessively from the plane of the face plate and are liable to damage the knife. The automatic projecting means obviates this danger. As shown, the last slice holder is attached to the usual clamp uprights by slotted lugs 3, and one of the lower spike-carrying shafts projects through a U-shaped frame 2, to which the face plate 1 is secured, and carries an arm 20 carrying a roller 23 on a pin 21 at its free end. As the holder approaches the cutting plane, the roller 23 contacts with a fixed stop which may be a meat-positioning plate. The shaft carrying the arm 20, and the other shafts which are geared and linked thereto, are thereby rotated, and the spikes are fully projected. The manual projection of the spikes is effected by depressing the handle 13, a leaf spring 18 engaging the top of the link 16 when the handle is fully depressed. The spring is displaced to permit the raising of the handle 13, by pushing it inwardly towards the spikecarrying spindles, by a finger piece 19. The arm 20 may be replaced by a link, pinion or star wheel and the invention may be applied to the small spikes of the holder described in Specification 370,660.

Title: Powder actuated tool
IPC: B25C1/14
Filed: 1964-08-20
Abstract: 1,074,194. Cartridge-actuated tools. OMARK INDUSTRIES Inc. Aug. 20, 1964 [Aug. 26, 1963], No. 34026/64. Heading B4C. A cartridge-actuated tool comprises a barrel member 24 and a breech block 78 which can be locked to each other in an operative position and rotated relative to one another in an inoperative position, the tool including a safety device for preventing cocking of the tool when the members are not in their operative position and for preventing relative rotation of the members from their operative position towards their inoperative position when the tool is cocked. The piston member 144 is held in the position shown, by spring fingers 156 formed on a sleeve 142 which is removable from the barrel 24. The barrel is mounted in a housing 55 made from a plastics material and urged to a forward position by a spring 44, the housing being connected to a breech housing 20 via a hinge ring 190 and a pin 202 rotatable in the latter housing; the barrel is connected to the breech block 78 by a bayonet-type joint. In operation, in order to insert a cartridge into a chamber 118 formed in the sleeve 142 the breech housing is first turned via the hinge ring relative to the barrel in order to disconnect the bayonet joint. The breech housing is then moved axially along the pin 202 until the end of the barrel is clear of the breech block and then rotated about the pin to an. open position (Fig. 14), in this position a ball (280, Fig. 10) is pressed by the hinge ring into a recess (286) in the barrel so that the latter cannot be moved axially. A cartridge is then inserted into the chamber 118 and the tool re-connected by reversing the above procedure. A fastener is inserted into the end 26 of the barrel and the end then pressed against a workpiece thereby causing the other end of the barrel to force the breech block rearwardly against the action of springs 82, 98 so as to cock the firing pin; when in the cocked position, a ball (280, Fig. 2) is pressed into a recess 284 in the hinge ring thereby preventing the opening of the tool. Upon depressing a trigger 120 a firing pin 86 is released to fire the cartridge. The explosive gases drive the piston 152 forwardly and are exhausted to atmosphere through slots in the sleeve 74 and a port in the barrel; a metal plate 164 is located in the housing 50 in order to protect the plastic material of the latter. If, due to insufficient resistance of the workpiece, the piston 152 is driven too far forwardly the ductile intermediate portion 145 strikes a hardened insert 150 in the barrel and thereby causes the intermediate portion to be extruded in the insert thus absorbing the energy. To eject a spent cartridge, the tool is opened and the sleeve 74 removed so that when the end of the plunger 146 is struck against a surface, a pressure is produced in a space 142 in the sleeve and thereby ejects the cartridge.

Abstract: 904,535. Semi-conductor rectifiers. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 5, 1960 [Oct. 6, 1959], No. 34097/60. Class 37. A rectifier assembly comprises a frame of electrically insulating material, the sides of which are slotted to form a plurality of teeth having slits in them, and a plurality of metal plates supported in the slits, a semi-conductor, e.g. Si, diode being clamped on each plate except one end-plate, and the diodes being connected in series. As shown, Fig. 1, each side of a frame 10 of moulded plastic has a generally rectangular piece cut out below the top and between the ends of the side to form shoulders 19, 20, and is slotted between shoulders 19, 20 to form teeth 21 which are slit at 23 to accommodate plates P1 . . . P16. To plates P1 and P16, respectively, are clamped bolts 31, 32 which extend within slots in the frame ends 14, 13 and form terminals of the assembly. To plates P2 . . . P16 are clamped the positive terminals 35 of semi-conductor diodes D2 . . . D16, the negative terminals 40 of which extend through clearance openings in adjacent plates, to which they are electrically connected by metal straps 50 fastened to their respective plates by rivets 51. As shown in Fig. 3, each plate is circular with three V-shaped circumferential recesses 26. Two recesses 26 fit into slits 23 while the other recess 26 accommodates a bar 27 which is secured to the frame ends 13, 14 by screws 30 (Fig. 1). The angular disposition of the plates is such that each intermediate diode is displaced 120 degrees in opposite directions from the diodes on adjacent plates. A surge-restraining capacitor 55 is connected across each diode; voltage dividing resistors may be connected across the capacitors. In operation, cooling air is drawn by convection horizontally between the plates and passes out of the open top of the frame. In a modification, Fig. 6, which in operation is placed over a duct through which cooling air is supplied under pressure, the frame 60 has flanges 70 which, together with vertical ribs 75, support a top-plate 61 of insulating material having equally-spaced slots 62. Plates P20 . . . P33 are rectangular (Fig. 7), the lower corners being supported in blind slits 78 in teeth 71, while the upper sides are supported in slits in ribs 80 formed on the under-surface of top-plate 61. In each of plates P21 . . . P33 the hole in which a diode D21 . . . D33 is clamped and the clearance opening are disposed as shown, the diodes being located in each of the four possible positions relative to the frame in turn. Capacitors 64, located above top-plate 61, comprise two sections having one electrode in common, and are connected to the plates of the assembly, as shown in Fig. 6. Voltage dividing resistors 104 are connected between the plates.

Abstract: 1466755 Pattern recognition systems INST ELEKT I VYCHIS TEKH AKAD NAUK LATVI SSR and LATVI NI INST EXPERIMENT I KLINICH MEDITSIN 2 Aug 1974 34188/74 Heading G4R Apparatus for determining the perimeter of an object includes a scanner 1, Fig. 1, for scanning the object in a number of equispaced parallel lines, 42, 43, &c., Fig. 9, the scanner feeding a threshold unit 2 which develops scan pulses, each pulse having a duration corresponding to the distance between successive boundaries of the object along a scan line. The distance AB between the leading edges of corresponding scan pulses in adjacent lines is determined in unit 5 (Fig. 2, not shown) as a difference pulse. The distance between the trailing edges is similarly determined. The difference pulses are quantized in unit 9. Additionally, coincidence pulses are generated by unit 6 (Fig. 3, not shown) when the leading or trailing edges of scan pulses in adjacent lines coincide, denoting that the object perimeter is here perpendicular to the scan line, e.g. as PQ. The quantized difference pulses and the coincidence pulses are combined in unit 8 to provide a signal which represents the perimeter length. The perimeter-determining unit 8 comprises an adder (26, Fig. 4, not shown) which adds the coincidence signals, the sum representing the total portion of the perimeter perpendicular to the scan direction, e.g. PQ + QR + RS + LM in the example shown. The sum of the sloping portions of the perimeter is determined by adding the quantized difference pulses (equivalent to AB, DE, HG, &c.) and values ai, a value ai being generated in respect of each quantized difference pulse. By gating the quantizing pulses from unit 10 with the scan pulses and counting the pulses from the gate a count representing the total area of the object may be obtained. The form factor (the square of the perimeter divided by the area) can then be determined. The scanning system may be associated with an electronic mask which gates only signals relating to a chosen region of the field of view to the remainder of the apparatus, to permit the perimeter, &c., of a selected one of a number of objects in the field to be determined. The apparatus may be used in automatic classification of cytological specimens.

Abstract: 639,930. Heavy current switches; sparking- preventing. ETABLISSEMENTS MERLIN & GERIN. Nov. 22, 1946, No. 34685. Conven.- tion date, Jan. 8. [Class 38 (v)] A switch, particularly of the gas-blast type and having auxiliary electrodes 18, 20, such as those described in Specification 616,031, to connect a voltage-limiting impedance 2 in shunt with the main contacts 1, 11 is provided with additional similar electrodes 19, 21 to connect a secondary shunt impedance 4 across the first electrodes 18, 20. Since the insulating nozzle 16 is of larger diameter than the nozzle 17, and relatively nearer to the mouth of the tube 22, the ionized gas from the main are will reach the electrodes 18, 20 initiating the arc 3 to connect the impedance 2 before the arc 5 is struck to connect the secondary impedance 4. For the same reason, when the main arc is extinguished, the accumulated gas in the tubes 19, 22 will maintain the arc 5 for a short time after the arc 3 is extinguished to disconnect the impedance 4. A tertiary resistance 8 may be connected across the arc 5, the circuit finally being opened by an isolator switch 6, Fig. 6. Other diagrammatic arrangements of the two impedances are given in Figs. 1-5 (not shown). The secondary impedance may alternatively be cut off by a series isolator which may be equipped with a gas-blast. The impedances 2, 4 may have, respectively, an increasing and a decreasing resistance/voltage characteristic. In switches not employing a gas blast to quench the main arc, the spark-gaps in series with both impedances may have independent quenching means. Specification 576,345 also is referred to.

Class 34(1) A process for drying filamentary tow comprises feeding the tow on to a rotating drum having a perforated peripheral surface and automatically advancing the tow along a helical path in contact with the drum whilst air is drawn into the drum through the perforated surface. Apparatus for drying a filamentary tow 16, Figs. 1, 2 accompanying the first Provisional Specification, comprises a rotatable drying drum 1 having a perforated peripheral surface and means to draw hot air into the drum through a major' proportion of the surface, automatic means being provided to advance the tow in a substantially helical path in contact with the drum. The drum and a feed roller 5 set at an angle to the axis of the drum are rotated by shafts 3, 7 respectively journalled in the wall of a cabinet 4. Hot air supplied to the cabinet and drum 1 through a duct 11 is exhausted through a duct 13 in a stationary flange 12 at one end of the drum. Hot air is also supplied under pressure through a duct 14 to a stationary duct 15 supported by the flange 12, which duct 15 has a mouth extending across the width of the drum so that as the leading end of the tow comes opposite the mouth the flow of air carries the tow over the roller 5. The tow then falls back on to the drum under the effect of suction and is slightly advanced along the drum due to the angle of the roller 5. In another embodiment the drum 1, Figs. 1 to 3 accompanyingthesecond Provisional Specification, has cleats 4 over which the tow passes, the tow being drawn on the perforated surface 2 by suction. Each cleat comprises a retractable longitudinal member 6 normally withdrawn in a channel 5 fixed to the drum and mounted on pins 7 projecting from a bar 8 which is slidable longitudinally in the channel 5. Extensions 13 of the member 6 engage cams 14 to raise the member as the drum rotates against the action of springs 9 connected to pins 10, 11 on the bar 8 and member 6 and thereby raises the turns of the tow. A projection 15 of the bar 8 engages a cam 16 to urge the bar 8 and member 6 longitudinally against the action of a spring 12 so that when each turn of the tow is lowered from the raised member 6 on to the channel 5 it will be displaced longitudinally. The tow may be carried on the drum in caternaries by inwardly curving the surface of the drum from the edges of the channels 5 to allow for contraction of the tow whilst drying.
