Filed: 1946-07-19
Abstract: 614,679. Batteries. CHLORIDE ELECTRICAL STORAGE CO., Ltd. (Longaker, E. L.). July 19, 1946, No. 21684. [Class 53] The plates and separators of an accumulator are covered by a shield in the form of a comb to prevent sediment from forming a conductive path between the upper edges of adjacent plates. Each tooth 25 of the shield 24 rests on the upper edges of the two separators 13 on opposite sides of a negative plate 11, as shown in Fig. 3. The comb is provided with upstanding ribs 28, 29 which abut against the undersides of the plate straps 15, 18 to hold it in position as shown in Fig. 1. Alternatively, the rib 29 may be formed at the end of the comb to abut against the underside of the accumulator lid. The part 26 of the comb may be provided with openings 27 to facilitate circulation of electrolyte and the escape of gas.

Title: Apparatus for making straight seams
IPC: D05B65/00
Filed: 1974-05-16
Abstract: 1454964 Sewing machines: workpiece guiding VIRGINIO RIMOLDI & C SpA 16 May 1974 [22 May 1973] 21697/74 Heading D1G When sewing long straight seams the trailing end of a workpiece 25 is hooked on an upstanding pin 37 on a block constrainer to slide along a hollow guiding rail 24. To keep the workpiece taut the sliding block is biassed away from the sewing machine by a counterweight 28 on the end of a cable 29. When the trailing end of the workpiece reaches the machine a photo-cell 22 detects it and subsequently stops the machine. The pin 37 is on a pivoted element 36 which slides down a ramp 40 so tilting the pin and allowing the workpiece to slip off it. The counterweight then pulls the pin and block back to the other end of the guiding rail. A clamp 23 can hold the workpiece after it has passed through the machine. A control box 18 has switches for starting, stopping, varying the time interval between the detecting of the trailing edge and stopping the machine and clamping the workpiece, and determining whether (a) the workpiece is hooked on the pin first and the machine starts immediately the presser foot is lowered, or (b) the presser foot is lowered first but the machine does not start until the workpiece is hooked on the pin and a starting button 48 pressed. A pedal 54 can lift the presser foot without change in the sewing cycle, and a counter 53 counts the number of cycles.

Filed: 1927-08-18
Abstract: 300,696. Redfern, C. G., (Naamlooze Vennootschap Machinerieen en Apparaten Fabriken). Aug. 18, 1927. Regulation, auto. matic. - An electric voltage regulator of the type comprising an adjustable resistance controlled by an electromagnet is provided with means for adjusting the springs &c. forming part of the apparatus by balancing them against a force equal to that exerted by the electromagnet when excited by the normal current, the magnet not being energized during the test and adjustment. In the arrangement shown the pressure on a carbon pile resistance E is exerted by an electromagnet B having a pivoted armature C controlled by a spring F. To adjust the mechanism the spring F is disconnected and a rod K carrying a weight L is passed through lugs J on the armature C until a mark M on the rod coincides with a mark 0 on the armature. The resistance E is then adjusted by means of a screw N until the armature is in its normal position. The spring F is then reconnected and the rod K is passed through the lugs from the other side until other marks coincide. The tension of the spring F is then adjusted by means of nuts P until the armature is again in its normal position.

In an analogue/digital converter of the type in which the analogue input is derived from a transducer with a known non-linear characteristic, the analogue signal at input 41 is compared with a reference signal from a voltage generator 25, clock pulses being accumulated in a counter 27, 28, 29, 30 until the signals are equal, the voltage generator 25 being controlled by the counter so that its output signal compensates for the non-linearity of the signal to be digitized. In the embodiment described, the unknown analogue signal is fed to an amplifier 44 via relay contacts 42a, 42b, 43a, 43b, positioned in accordance with the polarity of the input so that the input to comparator 40 is of constant polarity, the polarity bit being displayed (51). The binary coded decimal counter outputs are decoded into decimal form and displayed on number tubes. The two highest decades of the counter 29, 30, the latter only having two states, are connected to logic circuitry (Fig. 5) so that at predetermined counts transistors 76-80 are rendered conductive to connect associated resistances 51-75 to voltage generator 25. The voltage generator includes a capacitor 62 charged by pulses at input 58 applied to the base of a transistor 57, the resistors 71-75 being connected between the collector of the transistor 57 and earth to reduce the voltage change produced at the collector as the transistor is rendered conductive and non- conductive.

[Also in Division D1] Netting comprising strands 11, 21, Fig. 1, is formed by injection moulding cruciform plastics joints 16 at the cross-over points of the strands. As shown, a particular strand 14 led from a reel 15 is secured to strands 11 by a series of injection units 13 and severed by a cutter 17, the strands 11 then being further drawn off reels 10 prior to unreeling the next strand 14. Intermediate partial-width strands 22 are similarly secured. Trimmers 18, 19, e.g. employing a hot-wire are provided. Alternatively a strand 14 may be drawn across strands 11 during a moulding operation to be moved to the moulding position with displacement of strands 11. The injection unit, Fig. 5 (not shown), comprises a ram-fed injection cylinder (37) with conical nozzle (38), mould halves (23, 24) and a pneumatic support (43). Mould halves 23, 24, Fig. 3, comprise adjustable guides and jaws 31, 33 respectively, and fixed guides 32, the disposition of which components determines the deviation of the strands from their straight line paths at the point of crossover, see Fig. 4 (not reproduced). In an alternative form of mould, Figs. 6-8 (not shown), grooves (63) taper and deepen outwardly, the thread being gripped at the wider and shallower portions of the grooves. Preferably the mould is water cooled. The strands of the netting are flexible and incorporate thermoplastics, e.g. polyethylene monofilaments or twine. When used as electrified fencing, e.g. sheep fencing, the transverse strands 21, and/or the longitudinal strands 11 incorporate conductive filaments, e.g. metal filaments. In use, when strands 21 are non- conductive, any combination of strands 11 may be electrified. In particular, to eliminate earthing losses, the lowermost strand 11 is either not electrified or is connected to the earth terminal of an electric pulse generator and electrically connected at intervals to the fencing posts by conductors arranged to be driven into the ground with the ground spikes of the posts.
