Title: Improved crates for bottles
IPC: B65D85/30
Filed: 1946-11-28
Abstract: 626,677. Bottle crates; packing bottles. NIEBOER, H. A. Nov. 28,1946, No. 35371. [Classes 18 and 94(i)] [Also in Group XXIII] A crate for bottles comprises an upper tray 1 with a number of regularly spaced dished portions 3 on its under side to receive the tops of bottles, a lower tray 16 with a like number of compartments to receive the bottoms of the bottles and one or more tension members of variable length for securing the upper tray to the lower tray when the bottles are in position. As shown, the trays are detachably connected at each end by a turnbuckle device 13 hinged to the upper tray and formed at its lower end with an undercut toe 14 to engage a shelf 24 on the bottom tray 16. For stacking purposes, strengthening ribs 8 in the upper tray are cut away at 26, Fig. 3 so that a beading 25 on the lower tray of a superposed crate can fit within the periphery 2, whilst the provision of relatively small apertures in the corners of the lower tray permits one tray to be supported on the tops of the bottles of another loaded lower tray after removal of the upper tray. When the crate is empty, the turnbuckle 13 may be folded inwardly against the underside of the upper tray and a handle 10, which is engaged by spring loaded pins, is folded against the tray 1. A resilient plug 5 is provided in each dished portion to serve as a buffer for the bottle top. The provision of openings 4 in the upper tray allows the bottles to be washed in bulk and thereafter to drain, when the crate is turned upside down. The Provisional Specification also describes a crate with tension members in the form of coil springs which are anchored to the lower tray and held upright by inner tubes also connected to the lower tray, the upper ends of the springs having cross pins for detachable engagement with cam-faced pivoted claws on the upper tray.

Title: Cigarette hoppers
IPC: B65B19/04
Filed: 1975-08-28
Abstract: 1524843 Dispensing articles MOLINS Ltd 24 Aug 1976 [28 Aug 1975] 35485/75 Heading B8U A hopper for holding stacks of cigarettes in a cigarette-packing machine comprises outer walls 1 and internal partitions 2 which define vertical cigarette channels which are closed at their bottoms by a base plate 3 which is slotted to receive the partitions 2 and also to accommodate vertically reciprocable vanes 4 which are disposed in alignment with the centres of the channels, a plurality of reciprocable plungers 5, 6 being mounted to move forward from right to left in Fig. 1 in order to discharge cigarettes from the lower portions of each channel into a receiving pocket 7, the vanes 4 rising between the plungers to engage the lowest cigarette remaining in each channel as the plungers complete each forward stroke. The plungers 5 are pivotally mounted at their right-hand ends (not shown) and the base plate 3 is pivotally mounted at its left-hand end, and as the plungers return to the right both the plungers and base plate 3 are increasingly inclined downwardly as shown in Figs. 4 and 5 (not shown), and when the plungers clear the end of the hopper they, together with the base plate 3, pivot upwardly to resume their horizontal positions. The inclination of the plungers and base plate 3 enables lowering of the vanes 4 to commence earlier in the cycle than would be possible if the plungers and base plate remained horizontal. The resumption of a horizontal orientation by the plate 3 coincides with the vanes 4 reaching their lowest positions.

Title: Linearized analog-to-digital converters
IPC: H03M1/00

Abstract: 1,074,026. Selective signalling. LEEDS & NORTHRUP CO. Aug. 19, 1965 [Sept. 11, 1964], No. 35682/65. Heading G4H. In a non - linear voltage digitizer that approximates to a continuously varyin g characteristic, Fig. 1, by a plurality of straight-line segments the input is first compared with a sequence of predetermined reference voltages corresponding to the break - points B1, B2, . . . to determine in which range it lies and it is then digitized linearly on the appropriate straight line segment using conventional automatic selfbalancing techniques. The principle of the digitizer is shown in Fig. 7. First, with switches 17 and 27 in their zero positions, a sequence of reference currents corresponding to the break-points is applied to a current summing junction 13 which also receives a current IX proportional to the input voltage EX. This determines the range in which the input lies. Switches 17 and 27 are then set so as to provide the appropriate slope and zero offset for the range determined. Automatic self-balancing digitizing then follows. The Specification explains how to calibrate resistors 18 and 28 so as to fit a desired sequence of break-points. In the preferred embodiment, which uses transistors, the sequence of operation is controlled by a ring-counter. As it steps through its first four stages it causes a sequence of four reference voltages, corresponding to the four break-points and produced by a diode matrix in conjunction with the feedback resistors of the self-balancing loop, to be compared with the input. This determines the range the input lies in and during the fifth stage of the ring counter the appropriate slope and zero offset resistors are selected. Digitizing then proceeds normally.

[Also in Division F1] A liquid flow-proportioning apparatus for proportioning the flow of fuel from four fuel tanks 11, 12, 13, 14, Fig. 1, in an aircraft to a common header 27 supplying the engine, includes for each tank, a rotary vane pump 15, Fig. 2, positioned between a tank outlet pipe 19 and a pipe 23 leading to the header. The rotors 28 of the pumps are coupled to be rotable together by a hydraulic motor 29 and the width of the blades 30 of each rotor is related to the capacity of the associated tank to ensure the desired proportionality. Each pump is fitted with a by-pass valve comprising a fixed sleeve 35 having a series of ports 36 communicating through an annulus 40 and a passageway 32 to connect the discharge side of the pump with a return line 33 to the tank and a tubular spring- loaded valve member 41 including a piston 42 subjected on opposite faces through pasages 47, 46 to the pump suction and discharge pressures respectively to obturate the ports in accordance with the differential pressure. As differential pressure increases the inherent leakage past the vanes 30 increases whilst at the same time the valve member 41 moves to reduce leakage through the ports 36 and so maintain the total leakage substantially constant for a given speed of the rotor.

Abstract: 775,596. Registering output of machines. TELEDICTOR, Ltd. Dec. 2, 1955 [Dec. 21, 1954], No. 36876/54. Class 106 (4). [Also in Group XL (b)] Apparatus for registering the number of articles produced by a machine comprises an electrically-actuated counting-apparatus 10 in which the performance of a counting operation is dependent upon the action of two or more electric switches 16, 17, 18, the operation of each of which is dependent upon the performance of an operation essential to the production of the article in such a way that a counting operation can only be initiated when all the switches 16, 17, 18 are in closed circuit condition and completed only when they are all re-opened. In one embodiment of the invention, an operator places a blank on the bottom die of a press causing the sensing head of an electronic relay to cause the micro switch 18 to close, he then closes a safety guard to cause the switch 17 to close and finally engages a clutch to initiate downward movement of a platen, thereby causing the switch 16 to close. While open the switches 16, 17, 18 were in series with an electromagnetic relay 13, a rectifying unit 15, and secondary of a step-down transformer 14. When all the switches 16, 17, 18 are closed the relay 13 causes switches 21, 22 to put the switches 16, 17, 18 in parallel so that all have to be opened before the relay 13 is de-energized. The energization and de-energization of the relay 13 closes and then opens a switch 11 which initiates and then completes a counting operation of the electromechanical counter 10. In another embodiment two limit micro switches 17, 18 are closed when independent operations have been performed by two tools .respectively, and the third switch 16 is closed by a photo-electric unit when its beam is interrupted by a work-piece positioned by a conveyer in correct position relative to the two tools for their operations to be performed. Retraction of the tools and movement of the machined workpiece cause the subsequent opening of the switches 16, 17, 18 and comple-, tion of a counting operation.
