Title: A new or improved track testing or wheel aligning device for motor vehicles
IPC: G01B5/255
Filed: 1926-10-07
Abstract: 283,277. Watson, M. B. Oct. 7, 1926. Linear-dimension gauges.-An aligning device for gauging the inner edges of the rims of a pair of motor vehicle wheels comprises telescopic members, legs for supporting them at a suitable height, gauge arms extending from the outer or free ends of the members, an indicating member pivoted to one of the gauge arms, means urging this member in one direction, and a fixed index or scale for the indicating member. Two members 1, 2 are arranged to telescope one within the other. The member 1 comprises a flat rod with ratchet teeth the pitch of which correspond to the graduations which represent whole units of measurement while the member 2 comprises a tube of oval section. A pawl pivoted to the member 2 is adapted to engage the teeth on the member 1. Secured to the outer end of each member is a bifurcated head-piece 6 between the limbs of which a gauge arm 7 is pivoted on a pin 8 passing freely through holes in the limbs. Each pin 8 carries keyed to it a pair of legs 9 and a wing nut 11 holds the parts in assembled position. A projection 12 on each leg 9 coacts with a stop 13 on the head piece 6 to determine the operative position of the legs and a faced stop 14 on each gauge arm coacts similarly with a faced abutment 15 on the head piece to determine the correct operative position of the arm. By slackening the wing nut 8 the legs and arms may be folded beneath the members 1 and 2 for transport or storage. One gauge arm is adapted to contact directly with a wheel rim while the other carries a spring pressed indicating lever 17, 17a pivotally carried at the end of the arm one end 17 of the lever engaging the wheel rim while the other end moves over a scale 18 carried on the adjacent head piece. In a modified construction, each gauge arm is made in two parts one of which is mounted as before and carries a pin engaging a slot in the other part which may be adjusted vertically. The scale and indicating lever are carried by the adjustable part. This enables the measurement to be taken at axle height irrespective of the size of wheel. For wide tracks a bifurcated graduated extension member is secured to the member 1.

Title: Electronic tuning device for radios
IPC: H03J5/02
Filed: 1969-05-21
Abstract: 1,208,849. Radio tuning apparatus. FORD MOTOR CO. Ltd. 21 May, 1969 [17 June, 1968], No. 25921/69. Headings H3Q and H3T. A tuning device for a resonant circuit comprises pulse generating means, means for counting the pulses, and variable reactance means in the resonant circuit which are coupled to, and change the frequency of the resonant circuit according to the state of, the pulse counting means. The arrangement may be applied to radio receivers and transmitters, and in an embodiment comprising a superheterodyne receiver, an aerial tuned circuit comprising inductor 18, Fig. 1, and capacitor 20 is tuned to a succession of frequencies by means of parallel capacitors 22a-22k which are brought into circuit by means of reed switches 24a-24k. An R.F. intervalve coupling circuit comprising inductor 38 and capacitor 40 is similarly tuned by capacitors 42a-42k brought into circuit by switches 44a-44k and in addition a local oscillator circuit comprising conductor 54 and capacitor 56 are tuned by capacitors 62a-62k, brought into circuit by switches 64a-64k. Each set of switches 22a, 44a, 64a &c. is operated by means of series connected coils 66a, 68a, 70a &c. energized from the corresponding element 80a &c. of a binary counter 80 which is associated with corresponding memory units 94a &c. Manual tuning is controlled by means of a knob 72 rotation of which in either direction causes the counter to count in either a positive or negative direction, under control of a pulse generator comprising transistors 114, 118, 130, 132, Fig. 2. The speed of operation, i.e. of pulse generation is determined by the torque applied to knob 72, which varies the pressure applied to one of the pressure sensitive resistors 136, 138: the direction of operation of the counter is determined by whether switch 142 or switch 144 is opened to bias one of the transistors 154 or 156 conductive, these transistors determining the direction of operation of the counter (Fig. 3, not shown). In addition to manual tuning, push-button selection of stations may be effected under control of push-buttons 102V- 102Z, Fig. 1: individual memory units are associated with each push-button and each element of the counter (Fig. 5, not shown) such that if setting button 86 is pressed, together with any one of the push-buttons 102V-102Z that memory is energized which corresponds to the push-button concerned and to the station to which the arrangement has been tuned by means of knob 72. Subsequent depression of that push-button will then cause tuning to occur to the station so selected. The reed switches 24a, 44a, 64a &c. may be replaced by diode switching networks (Fig. 6, not shown). Furthermore, instead of the fixed capacitors 22a, 42a, 62a &c. and switches 24a, 44a, 64a &c. a single varactor diode may be used to tune each circuit, the outputs from the binary counter being converted from a digital to an analogue form by means of a ladder network employing resistors and diodes (Fig. 7, not shown).
