Title: Improvements in method and apparatus for measuring uniformity of tyres
IPC: G01M17/02
Filed: 1969-09-02
Abstract: 1,272,813. Active filter; D.C. component removing; zero crossing detector. UNIROYAL Inc. 2 Sept., 1969 [5 Sept., 1968], No. 43304/69. Heading H3T. [Also in Division G1] In apparatus for measuring variations in the radius of a tyre (known as "radial runout") the average of the runout signals is analysed to provide the first harmonic component only. The two runout signals from the linear motion potentiometers (Fig. 7) are averaged (Fig. 9, not shown) and fed to amplifiers A1, A2 (Fig. 10) with switch S1 closed. When the switch is opened by a sequence controller, the D.C. component of the input signal E 3 , stored in capacitor 37, is deducted from the input signal and amplified at A3 to be gated by a further sequence controlled switch S2 to restrict the output to one cycle only. This is fed to an analogue oscillator (Fig. 11) comprising, a summing amplifier A4 and two RC integrating amplifiers A5, A6 whose capacitors C are normally discharged through photoresistors 41, 42 held at low resistance values by lamp L. When the lamp is not lit, the single cycle input signal causes the circuit to produce a sinusoidal output voltage which is 90 degrees out of phase with the runout first harmonic voltage but with the same frequency and with a proportional amplitude. The sinusoidal voltage E, (Fig. 12), is fed to an amplitude detector, charging capacitor 44 to its peak value with transistors Q2, Q3 normally non-conducting. A small voltage is added via resistor 47 to compensate for the "Knee" characteristic of input diode D1, and the connected voltage amplified at A8 and indicated on meter AM. A cyclic reset signal from the sequence controller causes transistors Q2, Q3 to conduct and reset meter AM to zero. The measured amplitude is compared in amplifier A9 with a present voltage from potentiometer 46 to energize an alarm relay if it is exceeded. The sinusoidal voltage E 9  is also fed to an amplifier A10 (Fig. 13) which saturates when the voltage passed through zero with negative slope, corresponding to the maximum value of the runout voltage signal. This condition causes capacitor 51 to feed a positive pulser to transistor Q6 which conducts and energizes a relay TM (Fig. 2) whose contacts RC2 energize means for marking the location of maximum runout on the tyre. The sequencing of the measurement operation is effected by a controller (Fig. 16, not shown) fed with a pulse train derived from a magnetic pick-up associated with the rotating tyre.

Filed: 1960-12-22
Abstract: 943,097. Transistor oscillator circuits. HALROY PRODUCTS Ltd. Dec. 22, 1961 [Dec. 22, 1960], No. 44073/60. Heading H3T. [Also in Division H2] In a D.C. to D.C. converter incorporating one or more transistors in an oscillator whose output is fed through a transformer to a rectifying arrangement (e.g. a voltage doubler) including a load capacitor C1 which is charged to a high voltage, a coupling capacitor C2 is connected between the transformer and rectifying arrangement and has a sufficiently high impedance for the transistors not to be cut off but to maintain oscillation at a high level even though the load capacitor presents a very low impedance when the oscillator is switched on. With a load capacitor of 500 ÁF as used in an electronic flash unit, and a coupling capacitor of 0.1 to 0.5 ÁF instead of the conventional value of 10 ÁF the load capacitor may reach 80% full charge in 5 seconds instead of 18 (Figs. 2 and 3, not shown). The secondary winding turns may be increased by about 20%, to compensate for the reduction in load voltage due to the coupling capacitor. Specification 943,044 is referred to.

Title: Racing game
Inventor: NORMANDIN CAMILLE
IPC: A63F9/14
Filed: 1968-09-17
Abstract: 1,210,577. Apparatus for race game. C. NORMANDIN. 17 Sept., 1968, No. 44123/68. Heading A6H. Apparatus for mechanical race game, comprises, in combination, a plurality of tracks, racers moveable along the respective tracks, electric motor and worm drive, main drive gear wheel 8 with external segments of gear, 9, 10, 11, and with internal segments of gear 19. 20, 21. For each racer, a shaft 15 fitted with pinions 12, 13, 14 engages respectively and successively with said external segments to drive the racer, via sprocket 6 and flexible band 4 at a set of lower speeds. Also a shaft 25, fitted with pinions 22, 23, 24, engages respectively and successively with said internal segments to drive the racer, via gear wheel 41, gear wheel 18, sprocket 6 and flexible band 4, at a set of higher speeds, the rotation of shaft 15 then being overidden by the slipping of friction clutch 17. The amount of time for which the racer can 'be driven at higher speeds is limited, for when gear 41 is meshed with gear 18 the cursor wheel 49, prevented from turning by arm 50, travels down the threaded portion of shaft 25. When cursor wheel 49 abuts gear 41, pin 55 engages pin 48 and the cursor wheel then turns with shaft 25. In descending with the cursor wheel, arm 50 pushes a stud, via plunger 37, from its hole in upper plate 29, and the plate is then rotated by spring 36 about pivot 33. Shaft 25, its pinions 22, 23, 24 and its gear 41 are then swung) out of engagement with gear segments 19, 20, 21 and gear 18 respectively. The shaft 25 then becomes idle and the racer is driven by shaft 15. To accumulate more "time" at which the racer will be driven at the highe speeds the player pulls on rope 34 against the pull of spring 35. This rotates plate 31 about pivot 33 until plates 31 and 29 are aligned by stop 75. Further rotation of the plates engages pinion 26 with accumulator gear sector 27 Cursor wheel 49 is then driven, intermittently, up shaft 25 until it abuts against the underside of head 43. Pin 47 then engages with pin 55, and the cursor rotates with shaft 25. As cursor arm 50 rises it allows plunger arm 37 to rise allowing 'the stud to connect the already aligned plates 29 and 31. By releasing cable 34 the player may drive the racer at the higher speeds until the "time" accumulated is again expended. In play the racers are held against starting gate 56, with their accumulators charged and the friction clutches in each sprocket 6 slipping. Players have the choice of allowing their racer to run at the three successive lower speeds, or at the three successive higher speeds, thus expanding some of the "time" accumulated, or of, eventually, accumulating more time. The skill of the game lies in using various available speeds at the right time. The players are unable to see the mechanism.
