Title: Improvements in or relating to radio-receivers adapted to be tuned to a plurality ofpredetermined stations by means of push-buttons
IPC: H03J5/12
Filed: 1939-07-11
Abstract: 531,102. Push button tuning mechanism ; partly mechanical switches ; switches held set and freed mechanically. PHILIPS LAMPS, Ltd. July 11, 1939, No. 20205. Convention date, July 14, 1938. [Class 40 (v) ]Also in Groups XXXVI and XXXVII] In radio receivers in which tuning is effected by the displacement by means of push buttons of ferro-magnetic cores situated in inductances the necessary movement of the cores is reduced by dividing the wave range to be received into a number of bands of frequencies wherein the ratio between the lowest frequency and the highest is about 2. The wave band appropriate to the selected station is obtained by coupling the wave change switch to the push button mechanism. Depression of a push button 7 effects through a pin 8 the displacement of a plate 6 common to all the push buttons and carrying a core 4 displaceable in the tuning inductance coil. The coil is wound in two portions 1, 2 and together with the condenser 9 forms an oscillatory circuit which by operation of a threepoint switch embodying a condenser 11 can be arranged (a) for long wave reception with the coils 1 and 2 in series and in parallel with the condenser 9 (b) for one portion of the medium wave with the two windings 1, 2 in parallel with the condenser 9 and (c) for the other portion of the medium wave with the two windings 1, 2 in parallel with condensers 11 and 9. The switch comprises a rotor 13 and a stator 12 provided with groups of contacts 14, 15, 16 ; 17, 18, 19 ; and 22, 25 for linking the windings 12 and the condensers 9, 11 as set forth above. The switch is rotated to the required position by excitation of electromagnets 26, 27 which attract a piece of soft iron 28 on the rotor. The magnets are excited by current supplied at points 30, 31 and the circuit is completed on depressing the button 7 by means of a metallic rod 33 in the cap 32 of the button making contact with contacts 36, 37 located in notches in the guiding cylinder of the button which are connected by leads to the coils 26, 27. The depressed button is retained by a locking device 38 which on depression of the button is moved to the left against the action of a spring 39 so as to engage by means of arms 41, 42 projections 43, 44 on the rotor 13 which is thus (if required) moved to its middle position in order that it may be moved to the left or right as required by the magnets. The cap 32 as shown in Fig. 2 can be arranged on the guide in four different positions spaced 90 degrees apart so that the rod 33 makes contact with either or neither of the contacts 36, 37 according to the wave range of the station to which the push button in question is allocated. Exact setting of the push button to the required tuning point is obtained by adjusting the length of the rod 8.

Title: Improvements in and relating to spring clip devices
IPC: D06F55/02
Filed: 1945-08-10
Abstract: 593,125. Clips. BEILIN, L. Aug. 10, 1945, No. 20633. [Class 44] A spring clip, comprising a pair of similar twoarmed finger levers 1, has channelled clamping arms 2, the bottoms of the channels facing one another and being longitudinally arched at 4 where the levers are to fulcrum, so that they together form an opening in which is arranged the eye or C-shaped part 11 of a spring 10, which has extensions 12 passing through rectangular slots 9 on the clamping arm sides of the arched parts and lying in the channelled arms, thus pressing together the long clamping arms 2 and separating the short finger-gripping parts 3, which are turned up at an angle to the main part of the levers. The end walls 6 of the clamping arms are preferably inclined, thus closing the outer ends of the channels and forming a V-shaped entry 7, the bottoms of these walls forming stops for the ends of the spring 10, which is preferably a blade or strip spring longitudinally arched at its ends, the clamping arms 2 being correspondingly arched at 5 behind the V-entry 7 for linegripping purposes. Between this line-gripping part 5 and the fulcrum part 4 the levers may be straight, as may be the corresponding parts of the spring. The sides of the channels may diminish from the fulcrum part 4 towards the ends of the finger gripping arms 3 which may be broader than the clamping jaws to facilitate gripping them. The levers when of metal, e.g. steel or aluminium, are preferably pressed or stamped ; alternatively they are of moulded plastic. The channels of the levers may be wholly or partly covered, e.g. by an end tongue folded over the top of the channel. The clamping arms may open the spring by acting on its ends or on some intermediate position. In a modification, the extensions of the spring are straight, their outer ends bearing against stops formed by pressed-up tongues on the crests of the line-gripping arches of the clamping arms.

Abstract: 730,598. Measuring short time intervals electrically. CINEMA-TELEVISION, Ltd. Aug. 21, 1953 [Aug. 22, 1952], No. 21115/52. Class 40 (1).  Apparatus for measuring the duration of a time interval comprises means for counting the number of pulses from a first, crystal-controlled oscillator during that interval, and adding the algebraic sum of the pulses from a second, higher frequency oscillator for periods determined by the start of the interval and the first counted pulse from the first oscillator, and the end of the interval and the last counted pulse from the first oscillator. As shown, (Fig. 1), start and stop signals open and close respectively a gating circuit 2 to pass a series of pulses from a crystal-controlled oscillator 1 of known frequency to a counting circuit 3. The start signal also opens a gate 6 to pass pulses from a higher frequency oscillator 5 to a counter 8 until gate 6 is closed by the first pulse from oscillator 1 passed by gate 2. The stop signal also opens a gate 7 to pass pulses from oscillator 5 to a counter 9 until gate 7 is closed by the next pulse from oscillator 1. The algebraic sum of counts 8, 9 determined in unit 10, is added to count 3 to give the duration of the time interval between the start and stop signals. In another embodiment, Fig. 1 (Prov.), pulses from an oscillator 4 are again passed through a gate 3 to a counter 5, and in addition coincidence timing devices 7, 9 of the type described in Specification 729,931 measure the time between the start signal and the first pulse from oscillator 4 passing through gate 3, and the time between the last pulse from oscillator 4 through gate 3 and the stop signal. The algebraic sum of the counts in 5, 7 and 9 gives the duration of the time interval.
