Abstract: 1484251 Demonstration models ADAM ROUILLY (LONDON) Ltd 20 Dec 1974 [24 Sept 1973] 44725/73 Heading G5G A doll for medical demonstration and training purposes has at least part of its body formed from a translucent material simulating at least a portion of the skin of the doll, means, within the body being displaceable relative to the surface of the material, the means having a hue such that with said movement the simulated skin portion undergoes an apparent colour change. As shown, plates 10 are mounted on a slide 6 within the head of a doll for movement along guides 4, the movement being effected by drive means 8, e.g. an electric motor or a fluid pressure drive. The plates 10 are coloured red over the major part of their outer faces so that when they are moved close to the translucent face F of the head, the cheeks appear to redden. Liquids can be used to effect the colour change, particularly in a relatively small region such as the ear lobes. The liquid can be introduced into fixed passages or spaces within or immediately behind the hollow member, or can be contained in a flexible sac that is displaceable, e.g. by fluid pressure, into contact with the inner surface of the wall of the member.

Title: Sensor means
IPC: G01S13/931
Filed: 1972-10-11
Abstract: 1370549 Pulse radar SPERRY RAND CORP 11 Oct 1972 [22 Oct 1971] 46851/72 Heading H4D A distance measuring sensor comprises a transistor having a capacitance between collector and ground, the collector being coupled to a power supply, impedances between emitter and base and ground, a radiator transmission line coupled to the emitter and a receiver transmission line connected to the base such that short duration electromagnetic pulses launched by the radiator and reflected by an object are received by the receiver transmission line and means connected to the emitter to sense the repetition frequency of the transmitted pulses. The embodiment described is a motor vehicle safety device which operates brakes or an inflatable gas-bag if impending collision is detected. Closure of switch 20 which may be the ignition switch supplies a voltage 21 to charge capacitor 33 through resistor 30. Capacitor 33 may be formed from the stray capacitance inherent in the avalanche type transistor 31. At a certain voltage across 33, transistor 31 breaks down, rapidly discharging the capacitor via resistor 29. Thus a sharp, subnanosecond pulse is generated which is transmitted along coaxial cable 12 to a radiator transmission line 5 (Fig. 3, not shown). A suitable type is described in Specification 1,293,737 (Division H4). If there is no vehicle within a predetermined range, second and further pulses are generated by the breaking down of transistor 31, thus producing a steady stream of pulses at a fixed frequency. If the vehicle approaches within a predetermined range, a reflected signal will be received by transmission line antenna 6 and passed to the base of transistor 31. The amplitude of the received pulse is enough to trigger the transistor to produce a pulse. Thus the frequency of the output pulses at the emitter are inversely proportional to range. These pulses are integrated and the range displayed on meter 22. At a first warning range denoted by a frequency f 1  and detected by resonant circuit 143 an actuator 44 lights amber lamp 23 and/or applies the vehicle brakes. At a second alarm range, red lamp 24 is lit and the vehicle safety device, e.g. an inflatable gas-bag is actuated (Fig. 7, not shown). Instead of being actuated by the ignition switch, the capacitor 33 may be charged via switch 291 actuated by relay 290 which receives a signal from the speedometer (Fig. 6, not shown) such that the system functions only at speeds in excess of e.g. 8-10 m.p.h. The short sub-nanosecond pulses transmitted by the dispersionless antenna contain only very low components at any particular frequency and will not be detected by broad band receivers e.g. communication receivers in the vicinity. Vehicles may be equipped with rearwardly facing systems which receive and re-transmit pulses from following vehicles.

Title: Optical wave guide pair acoustic wave controlled switch
IPC: G02B6/24
Filed: 1973-10-08
Abstract: 1448563 Controlling light TEXAS INSTRUMENTS Inc 8 Oct 1973 [26 Oct 1972] 46878/73 Heading H4F Light propagating in one of a pair of guides is selectively switched to the other guide by causing a surface acoustic wave (SAW) to interact with at least one of the guides so as to alter the characteristics of the guide at a region where the guides may be optically coupled and/or to alter the characteristics of the light propagating therein such that it may be optically coupled into the other guide. In Fig. 7, the fundamental mode TE 1a  in guide A cannot be matched to any mode in guide B. A SAW from a transducer 47 acts only in guide A where the guides are well spaced, and has a propagation reactor such that the fundamental mode is converted to a mode TE 3a  which is matched to the fundamental TE 16  of guide B, so that optical coupling occurs when the guides are sufficiently close. In Fig. 1, the guides 10, 12 are confined between lower index layers 14, 16, and the SAW transducer 35 consists of interdigitated electrode pairs 20, 22 on a piezoelectric layer 18 on layer 14. The SAW interacts with both guides at the region where optical coupling may occur as a result of altering the effective propagation constants of the guides, e.g. via collinear acoustic-optic mode conversion, or by altering the properties of the guides themselves. The SAW may propagate longitudinally of the guide as shown, or transversely.

Abstract: 1,061,403. Electronic counters. SPECTO Ltd. Nov. 21, 1963 [Dec. 14, 1962], No. 47259/62. Heading G4A. An electrical decade counting circuit arrangement, comprises two scale-of-two counting stages and a scale-of-three counting stage serially connected and with a feed-back connection serving to zeroize the arrangement at a count of ten. Each scale-of-two counter consists of a transistor trigger (VT1, VT2 and VT3, VT4, (Fig. not shown) and the scale of three counter consists of aring (VT5, VT6, VT7). In each trigger the input pulses are routed to the bases of the triggers which are next to conduct by diodes (MR1, MR2, MR3, MR4). The input is to a common base connection and applied through capacitors (C1, C2) to the diodes. If (VT1) is conducting the capacitor (C1) charges through a connection from the collector via resistor (R1). The next pulse is accordingly prevented from passing through the diode (MR1) and passes to the base of (VT2) since the capacitor (C2) is uncharged, the trigger therefore switches. A carry lead from the collector of (VT2) passes to the input of the second trigger providing a pulse at each two input pulses. In the zero condition (VT1, VT3 and VT5) are cut off the others conduct. Diodes (MR6 and MR8) are reverse biased by capacitors (C5 and C7) which are charged by potentiometers (R6, R8 and R9, R10). At a count of four (VT4) gives a pulse which passes through diode (MR7) to cut off (VT6) thereby applying a rise to the base of (VT5), which conducts. Diodes (MR6 and MR7) are now reverse biased and diode (MR8) is not. When (VT4) gives the next output (at count of 8) the pulse cuts off (VT7). This causes a rise in the potential of base of (VT6) which conducts. At a count of ten the output of (VT2) passes through diode (VT5) cutting off (VT5) so that the scaleof-three counter reverts to its zero condition. At this change the trigger (VT3, VT4) does not switch since diode (MR4) is biased off by capacitor (C4) charged through a connection from (VT7). At a count of ten, therefore, the circuit reverts to the zero condition.
