Title: An improved method and apparatus for assembling box lids on box bottoms
Inventor: BASHFORD JACK
IPC: B65B7/28
Filed: 1958-10-21
Abstract: 890,434. Endless conveyers. ANDREW & SUTER Ltd. Oct. 21, 1959 [Oct. 21, 1958], No. 33690/58. Class 78 (1). [Also in Group XVII] A machine for telescoping lids over box bodies comprises a conveyer for the lids which converges with a conveyer for the bodies and has means for turning the lids over through 180 degrees, and also means preventing the front part of the lid descending too far over the walls of the body so that all four walls of the lid engage outside the four walls of the body before the lid and base are moved into the fully closed position. The conveyer 2 for the bodies and the conveyer 3 for the lids are belt-driven from an electric motor 6. The conveyer 3 delivers the lids to a shoot 16, a driven belt 24 protruding through a rectangular cut out in the base of the shoot. The lids are delivered from a lid wrapping machine by a transversely positioned conveyer 54 (Fig. 3) and by means of an inclined guide-plate 55 are stood on one of their sides on the conveyer 3 (see Fig. 3). A guide 68<SP>1</SP> inclined across the conveyer 3 and another guide 61 turn the lids over so that their tops are uppermost. At the exit end of the shoot 16 a brush 36 checks each lid until its forward end is engaged by a box on the conveyer 2 (Fig. 6). The box draws the lid on to guides 41 which position the lid and box in parallel relation after which the lid and box pass beneath a brush 46 which presses them together and the closed boxes are delivered to a platform 86. A resiliently mounted roller 38 (Fig. 6) checks the lid which is immediately behind the lid being fitted to a box. The boxes on the conveyer 2 are checked by a brush 51 until a slat 53 on the conveyer engages the box and forces it past the brush, the slats thereby space the boxes on the conveyer. Guide rails at the sides of the two conveyers are adjustable to accommodate different size boxes and lids. The angle of the shoot is adjustable by screw means. In another embodiment (Fig. 8) a brush 144, which corresponds to the brush 36, is connected by a linkage to one of two brushes 152, 157 which grip the lateral sides of the lids. When a box body draws a lid past the brush 144, the linkage moves the brush 152 and releases the next lid. In this embodiment the box body and lid are finally aligned by rollers 163, 164, respectively (Fig. 10), and a vertical rod 197 realigns a lid that is misplaced on the conveyer. In a modification, the brushes 152, 157 may be replaced by guide plates.

Filed: 1971-07-19
Abstract: 1369841 Ignition systems timing ignition COMPAGNIE DES COMPTEURS 19 July 1971 [17 July 1970] 33801/71 Heading F1B In an ignition system for an internal-combustion engine, a sparking circuit 36 is controlled to produce a spark at a time which is a function of the charging and/or discharging characteristics of two capacitors C 1 , C 2  the first capacitor C 1  being charged during a fixed time and the second capacitor C 2  being charged during a variable time which is a function of the speed of the engine. The first capacitor at least partially controls via an amplifier (transistor 43) the charging characteristic of the second capacitor and at least the second capacitor includes a charging circuit comprising a plurality of distinct voltage threshold elements 38, 39, 38a, 39a, 38b, 39b such that the state of charge that it reaches is a function both of the speed of the engine and the voltage thresholds introduced by the threshold elements. As shown a transistor 35 is provided whose base is connected to the second capacitor and to the emitter collector circuit of the transistor 43 comprising the amplifier. The transistor 35 is saturated at the sparking time and is arranged to cause on saturation the discharge of an ignition coil 49, 49a for generating the spark. The determination of the position of the top dead centre of at least one of the pistions of the engine is effected by at least one sector 8, 9 driven in rotation by the engine and causing the blocking of an oscillator 7 when the sector passes in front of a coil 10 of the oscillator. The oscillator generates rectangular signals during the existence of which the second capacitor is charged. In a modification (not shown) the charging circuit of the second capacitor comprises two sets of resistors and diodes in parallel and between these two sets an electronic amplifier. In another modification the charging circuit comprises two non-linear amplifiers disposed in opposition so that the charging current supplied to the capacitor C 2  is the difference between the charging currents of the two amplifiers.

Title: Improvements in or relating to control valves for pipe organs
IPC: G10B3/06
Filed: 1945-12-14
Abstract: 605,096. Electrically-actuated valves. HOMER, H. W. Dec. 14, 1945, No. 33860. [Class 135] [Also in Group XXXVIII] In an electromagneticallyoperated valve, the pallet is opened in the direction of air flow to improve the smoothness of air flow and prevent too rapid closing. The valve is mounted in a closed chamber. In one form, an electromagnet 25, Fig. 1, attracts its pivoted armature 21 which raises the pallet 18 through a toggle link 20, so allowing air to pass from passage 12 to outlet 15. This form of toggle link enables the return spring 24 to exert an increasing pressure on the valve as it closes, thereby overcoming the wind pressure. In a balanced valve arrangement the pallet 30, Fig. 2, is mounted on a sliding stem 33 and is moved off its seating when magnet 39 attracts its armature 37. The valve is balanced by a bellows 47, whose interior communicates with the chamber 32 through orifices 49, 50, and the valve is normally held. closed by a return spring 41. In order to make the valve close more slowly than it opens leather non-return valves 51 are placed over the passages 50 to cause the air trapped in the bellows 47 to pass out through a single passage 49 whose effective area can be varied as by a screw 52.

Title: Improvements relating to apparatus for generating waveforms for testing television equipment
Inventor: HUNTLEY KEITH GORDON
IPC: H04N17/00
Filed: 1954-11-27
Abstract: 820,305. Digital to analogue converters. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 28, 1955 [Nov. 27, 1954], No. 34445/54. Class 40 (1). [Also in Group XL (b)] A complex waveform (for testing the video stages of a television receiver) is generated by using a flying spot scanner to read a punched card or printed film carrying a binary digital coded version of the required waveform, and then converting the code signals to their analogue value. In one embodiment, the image of a raster produced on a cathode-ray tube 1 is focused on to a record 9, and light transmitted through the record 9 is collected on to a photocell 14 by a condenser lens 15. The record 9 consists either of a photographic plate using black, grey, and white, respectively, for 0, 1 and a code synchronizing pulse, or a punched card with regular holes to represent 1 and elongated holes to represent the code synchronizing pulses, the holes being explored by superimposing a 50 Mc/s. " spot-wobble " on the line scan. The code synchronizing pulses are inserted after each code group of 7 digits. The record 9 carries as many rows of characters as there are lines in the C.R.T. raster-8 to 12 are suggested. The output pulse waveform from the photo-cell 14 is amplified at 15a and applied to a code synchronizing pulse separator 17 and to a delay line store 16 which has tappings connected to analogue gates 18 ... 24. Reference currents graded on a binary scale are applied to the analogue gates, gate 18 having the full current, gate 19 having half that current &c. The gates are normally closed, but are opened in turn by the pulses from the delay line 16 and apply the sum of the selected currents to an analogue store 27, each time the gate 26 is opened by a code synchronizing pulse from the separator 25. Thus during each line scan an analogue voltage is built up. After the last code synchronizing pulse there is a period during which no light is transmitted by the record so that the delay line store then contains only " zeros." At this stage an auxiliary pulse is applied to the gate 26 and this causes the analogue store to reduce to zero. Thereafter scanning the next line commences. In a modification, Fig. 4 (not shown), three simultaneous ' outputs for colour television are provided by coding the outputs serially on the record and separating the pulse signals by means of a tapped delay line. In a further modification, Fig. 5 (not shown), the three outputs are coded on the record in three colours and separated by a system of dichroic mirrors on to three photocells. In a further modification, Fig. 6, (not shown), three side-by-side images of the cathode-ray tube are produced on the coded record by means of beam-splitting mirrors and the three coded outputs are read by individual photo-cells.
