Abstract: 709,092. Weighing-apparatus. AVERY, Ltd., W. & T. (Schember & Sohne, Bruckenwaagen-und Maschinenfabriken Akt.-Ges, C.). Sept. 1, 1952, No. 21959/52. Class 143 A plurality of roller poise weights are carried by a single weighbeam, and are traversed by a plurality of catch rods. In the embodiment described, the force P, Fig. 1, is transmitted through lever 2 and link 3 to the weighbeam 4 pivoted at 5, 6. The beam carries four roller weights 8, 10, 12, 14 in sets of grooves 7, 9, 11, 13, respectively, the weights coresponding to the values 1000, 100, 10 and 1 respectively. The weights are traversed by forked and racked catch rods 27 ... 30, one behind the other, operated by teeth on four type discs 23 ... 26, rotated through coaxial hollow shafts 19 ... 22 by adjusting levers 15 ... 18. The discs are provided with clicks 31 .. 34 which locate the forks of the catch rods, so that in their rest positions they are out of contact with the weights. The type characters are located between the teeth on the discs 23 ... 26, Fig. 4 (not shown), and the weight is printed on card 36 by device 35. For visual indication of the weight, the setting lever hubs bear numbers which appear in an inspection opening, Fig. 5 (not shown). A single mechanism may actuate the locking and release of the weighbeam, the balance test and the printing. Thus in the four positions of the cam disc 39. Fig. 6a, operated by the printing lever 38. (i) the weighbeam 4 is locked by the projection P, (ii) the weighbeam 4'is released for balancing, (iii) the lever 40, controlled by dashpot D, is released to check the balance position and lock beam 4 if correct and (iv) the printing lever 35 is operated. In a modified actuating device, the cam disc 39, Fig. 7a, releases two feelers 43, 40 operating consecutively. If the tongues 45 of feeler 43 meets the tongue 46 of the beam 4, while the tongue of feeler 40 enters the opening 42 of beam 4, then the projection 48 turning with cam 39 can pass the projection 47 on the feeler 40 and printing can take place. The tare of the unloaded scale is adjusted to zero by sliding open the door 51, Fig. 8a, and adjusting the screw 49. The member 52, which slides with the door, depresses the lever 54, through stud 53, to lock the printing lever 38 in position (ii) and the catch rods 27 ... 30 in their zero position by lever 55. When the door 51 is closed, the catch rods remain locked, the lever 55 being locked by the catch 56, but the printing lever 38 is released. When the balance has been checked and the figure nil printed, the arm 57 releases the catch 56 to release the catch rods 27 ... 30.

Abstract: 959,725. Endless conveyers. LECAB RULLBANOR A.B. June 7, 1962, No. 22056/62. Heading B8A. A paternoster elevator of the kind in which parallel endless chains 6 carry a plurality of projecting forked goods-carrying platforms 7, and a number of roller conveyers e.g. 43, 54, 56 at different levels are arranged for delivering goods to or receiving goods from the elevator comprises a goods transfer platform composed of a plurality of deep loops 23, 24, connected by spaced parallel legs 25 disposed in a common plane mounted in bearings 21 on arms 20 keyed to a shaft 16 driven in synchronism with the elevator chains 6 by a chain 17 running round a sprocket 18 and a sprocket 19 keyed to a drive shaft 2. Sprockets 26, 28, keyed to shafts 22, 16 and connected by chains 29, ensure that each transfer platform 23, 24, 25 remains horizontal as it is rotated about the shaft 16. Goods items 31, 31<SP>1</SP>, 31<SP>11</SP> are fed by gravity on a roller conveyer 43 and are held by a stop 45 on rollers 40 which, together with rollers 32 on spaced parallel arms 33 are mounted on a yoke pivoted at 36 by yoke arms 35. When the transfer platform 23, 24, 25 has lifted a goods item 31 off the rollers 32 an eccentric (not shown) pivots the yoke about the pivot 36 to lift the next goods item 31<SP>1</SP> sufficiently to clear the stop 45 so that it can run down on to the rollers 32. The end roller 40 acts as a stop (Fig. 2, not shown) to prevent goods item 31<SP>11</SP> from following the goods item 311 too closely. The transfer platform 23, 24, 25 travels faster than the chains 6 and so overtakes a platform 7 and deposits the goods item 31 on the tines 8 which pass through the loops 23, 24. Transfer from the rollers 32 to the transfer platform 23, 24, 25 is effected similarly. The transfer mechanism may also be used to unload goods from the elevator, Fig. 1 shows two loading and two unloading stations. Roller conveyers 54, 56 are used conventionally to load and unload the elevator at the base.

Title: Transistor oscillator and rectifier unit
IPC: H04N3/18
Filed: 1964-05-29
Abstract: 1,039,413. Cathode-ray tube circuits; switching transistor oscillators. FERNSEH G.m.b.H. May 29, 1964 [May 30, 1963], No. 22323/64. Headings H3T and H4T. [Also in Division H2] In a D.C. to D.C. converter circuit for supplying high-voltage to a pick-up tube in a television camera, which circuit comprises a transistor oscillator followed by a rectifier, a protection circuit 25 is provided to provide a negative blocking voltage on the cathode of the pick-up tube to suppress the electron beam on the failure of a beam deflection generator 26, and a further protection arrangement is provided such that should the power supply 24 to the protecting circuit 25 fail (thereby disabling this protection facility) the transistor oscillator is stopped and hence the high voltage is removed. As shown, the transistor oscillator comprises a pair of transistors 3, 4, connected in push-pull, the collector electrodes being connected to a main winding 5 on a transformer 2 and the base electrodes being connected to a feedback winding 6. The emitters are connected to a third winding 9 whose centre tap is connected to one pole of the D.C. input. The other pole is connected to the centre tap of the winding 5, and also to the centre tap of winding 6 via a circuit comprising a transistor 21 and an RC combination 7, 8. If the resistance of this circuit is very high, oscillations cannot continue. Thus, whilst the potential at 22 (which depends on the supply 24) is sufficient to break down a Zener diode 23 the transistor 21 conducts and the oscillator operates, but if the source 24 fails, transistor 21 is blocked, the oscillations cease, and hence the high voltage is removed. The arrangement provides several rectified outputs for different electrodes on the pick-up tube.

Abstract: 729,431. Fuel injectors. HARTRIDGE, L. Sept. 25, 1952 [Sept. 25, 1951], No. 22436/51. Class 7(3). [Also in Group XXVIII] A device for testing fuel injection nozzles and pumps comprises means associated with the valve of a nozzle fed by the injection pump for producing an electrical pulse which operates a gaseous discharge lamp for illuminating stroboscopically an indicating element attached to or associated with the pump shaft. A fuel injector 3 is provided with a rod 20 in contact with the needle valve 10, the upper tip of which rod comprises a permanent magnet co-operating with an induction coil 17 to produce an electrical pulse each time the valve 10 is raised. The pulses, after amplification by a transformer T and amplifier A, operate a neon discharge lamp N arranged to illuminate a pointer P on the driving shaft of the pump R moving over a scale S. For testing the pump one or more of the injectors 3 are connected to the pump outlets D. Each delivery operation of the pump produces a flash from the tube N which coincides with the beginning of injection and the phase of the injection relative to the top dead centre of each pump piston can be read from the apparently stationary positions of the rotating pointer P in relation to graduations on the scale S representing the top dead centre positions of the pump pistons. For testing injectors the top cap of an injector is removed and replaced by a casing 16 carrying the rod 20 and coil 17. The injector is then connected to the pump and tested as above. Shut-off valves may be provided in the pipes connecting the injectors to the pumps to determine which of a number of pump elements or injectors is faulty, or switches in the induction coil circuits may serve the same purpose. The rod 20 may be a permanent magnet or an electromagnet or the induction coil may be replaced by a crystal or carbon pile resistance subject to the vibrations of the valve 10. A rectifier W may be used to short circuit the pulses produced when the valve 10 closes.
