Filed: 1965-12-14
Abstract: 1,131,112. Lathes. CHARLES CHURCHILL & CO. Ltd. 12 Dec., 1966 [14 Dec., 1965], No. 53077/65. Heading B3T. [Also in Division G3] A device for a profiling lathe for correcting machining errors due to say tool wear comprises a unit for gauging a work piece and generating an error signal representing the difference between the gauged dimension and the required size, a template displacing mechanism together with a device giving a displacement signal, a unit providing a difference signal between the error signal and displacement signal, and hydraulic means responsive to the difference signal for moving the template to reduce the difference signal. Each workpiece is profiled in the normal way, from a template 19 and is then compared dimensionally with a reference workpiece (27) (Fig. 1, not shown), any difference causing vertical displacement of the template (19) by a double acting hydraulic motor (Fig. 8, not shown). The workpiece is then re-machined to a closer tolerance.

Abstract: 1,203,956. Push-button tuners. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 Nov., 1967 [25 Nov., 1966], No. 53760/67. Heading H3Q. Each button in a tuner can be pressed in to switch into circuit a tuning element (e.g. a potentiometer for tuning a varicap diode) and simultaneously to set a band switch according to the angular position of a member which can be rotated by the button, the member carrying scales one of which is in view at a time to show the band selected; tuning within the band is effected by rotating a housing which surrounds the scales. The button 4 when pressed in operates contacts 8 (Fig. 1) to bring in a tuning element A, and the rear end of the button shaft 2 carries a toothed hub 26 (Fig. 2) whose teeth 27 either operate spring-loaded flaps 29 (connected to the band switch, not shown) or pass through notches 31 in the flaps, depending on the angular position of the shaft 2. To change the band setting the button is pulled out against a spring 15 until flats 25 are free from a fixed surface 22 and then rotated to set the hub 26 in a different angular position. For normal operation the button is pressed in against a spring 24 until a latching bar 18 engages a groove 20; this releases the previously pressed button in known manner. The button spindle 2 carries a coaxial transparent housing 6 (Fig. 1) in which is a sleeve 11 connected to the contact carrier 8. The sleeve has markings 34 of which one row is visible according to the angular setting of the band switch. Rotation of the housing 6 by milled portion 13 causes rotation of a channel indicator 9 and the tuning element A, and the front end of the indicator 9 shows to which channel of the band the element is tuned. The whole frame 1 forms an insertible unit which can be pushed into the tuner or withdrawn so that the tuning scales are visible.

Patent GB-543478-A (GB)
Abstract: 543,478. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd. April 22, 1941, No. 5193. Convention date, April 22, 1940. [Class 38 (v)] In an arrangement for connecting a load circuit L7, L8, L9 alternatively to a main supply circuit 1 or to an auxiliary circuit 3 either automatically, in accordance with the condition of the supply 1, or manually, two electromagnetic switches 5, 6, which may also be manually operated at will, are inter-locked by linkage 7l, 7m, so that when one switch is " on " the other is " off." The switches 5, 6, respectively, connect the load to the two sources of supply and each comprises an electromagnet, e.g. 5a which moves its contact-shaft 5f "on" against the action of a spring, the energizing circuit of the magnet being broken by auxiliary contacts 6e on the other switch as this is opened. The spring tends to return the switch 5 "off" " but cannot do so since the link 7l is now in line with the axis 7e, forming a toggle, which is broken later when the other electromagnet 6a is energized. Should vibration open the switch 5 the closure of the auxiliary contacts 6e will re-energize the magnet 5a and reclose the switch 5. The magnets 5, 6 are selectively energized according to the voltage of the supply circuit 1. Should the voltage fall a relay 15a is de-energized which serves to complete a ci.rcuit to the electromagnet 6a with consequent closure of switch 6 and connection of the load circuit to the auxiliary supply 3. Should the voltage of circuit 1 rise again relay 15a. is energized, magnet 5a energized, swich 5 closed and the load circuit connected to main supply 1. Switches 5, 6 may also be manually operated by a rotary handle which drives a pin engaging with lost motion the disc 7g. The handle simultaneously operates a cam 8 which serves to open switches 9, 10 in the energizing circuits of the magnets 5a, 6a.

Abstract: 1386317 Rotary internal combustion engines GENERAL MOTORS CORP 7 Dec 1972 [23 Dec 1971] 56497/72 Heading F1F A rotary-piston internal combustion engine of the trochoidal type comprises an ignition system whereby a series of sparks are caused by a single spark plug almost simultaneously. The spark plug 40 is mounted on the housing 13 on the minor axis thereof and has an electrode 43 which is spaced from a rectangularly sectioned electrode 54 mounted on the rotor 22 by a gap 58 when the piston 22 is in the dead centre position with maximum compression. Electrode 54 is mounted on a ceramic bridge 50 in a transfer channel 38 of the respective rotor face and is thus insulated from the rotor 22. The trailing end of electrode 54 is spaced by a gap 60 from an electrode 56 earthed to the rotor 22. The gaps 58, 60 are substantially the same width but gap 58 has a lower capacitance so that when a voltage is applied between plug 40 and earthed electrode 56, the gap takes most of the voltage and a spark is created. Once the spark is made, the gap 60 takes all the voltage and a further spark very soon occurs at this gap thus igniting gases in the trailing part of chamber 28. Also described are  embodiments with more gaps created by intermediate electrodes Figs. 4 and 5 (not shown), and with a spark plug in each rotor face Figs. 6 and 7 (not shown). It is also stated that the earthed electrode may be on the housing.

When a switch 13 is closed a full wave rectifier bridge including diodes 28 supplies charging current to the capacitor 56 via a transistor 42 of the monostable device 40. The capacitor does not charge sufficiently to trigger the thyristor. When the rising voltage output of the bridge rectifier exceeds the breakdown potential of the Zener diode 38, a transistor 41 is switched on thus switching off the transistor 42. As the output of the bridge rectifier passes its peak and starts to fall, the transistor 41 is switched off when the Zener diode becomes non-conductive thereby switching on the transistor 42 and enabling the capacitor 56 to charge sufficiently to trigger the thyristor 60. A spark is therefore generated at the electrodes 20, 21. The thyristor may be replaced by a thyratron or a triac.
