Abstract: 1,007,798. Controlling motor vehicles. N. WHILEY. Feb. 28, 1964 [Dec. 4, 1962], No. 45816/62. Heading B7H. [Also in Division H2] Before the starter motor of an agricultural tractor can be energized a switch fitted beneath the driving seat must be closed by depression of the seat under the weight of the driver. The switch (Fig. I) includes terminals 15, 16 embedded in an insulating block 14 and connected by leads 20, 21 to the starting motor circuit, and a metal contact 25 biased to bridge the terminals 15, 16 by a light spring 28 is prevented from so doing by a plunger 2 which is adjustably loaded by a stronger spring 5 and engages a pin 26 extending from the contact 25.

Title: Tdm telecommunications systems
Inventor: HARTMANN L
IPC: H04Q11/04
Filed: 1970-09-28
Abstract: 1316343 Automatic exchange systems SIEMENS AG 28 Sept 1970 [30 Sept 1969] 46006/70 Heading H4K A TDM telecommunication link includes a first store at the transmitting end which reads in signals at a first rate corresponding to the frequency at which they are received, stores them in successive storage locations and reads them out at a second faster rate to provide pauses in transmission into which control signals are inserted, and at the receiving end the control signals are divided out and the remaining signals fed to a second retiming store from which they are read out at said first rate. In one embodiment shown the bits of a PCM TDM signal stream incoming at A si are alternately entered in a pair of bi-stables forming a store Sps under the control of a flip-flop FF1 at a frequency A fo. The bits stored are alternately read out under the control of a flip-flop FF2 at a slightly higher frequency A f1. After 24 bits comprising three 8 bit channels have been read out the flip-flop FF2 can be halted for one step providing a one bit space in the outgoing signal stream. A one bit control signal is inserted in this space via terminal As and an OR gate G 02 and the combined stream transmitted to the receiving station. Since there are 24 channels in a time frame an 8 bit control signal code can be transmitted with the bits distributed between groups of three channels. At the receiving station the control signals are divided out and a second retiming store operating in similar fashion to the store at the transmitting station re-distributes the signal stream to its original 24 frame format. A second embodiment with nine storage location selected cyclically in each store enables a 24 channel PCM TDM stream to be retimed in similar fashion to provide a 25 channel on which a complete 8 bit control signal code can be transmitted in a single time slot.

Abstract: 1,149,727. Musical boxes. M. I. GLASS, [trading as MARVIN GLASS & ASSOCIATES]. 17 Oct., 1966 [22 Oct., 1965], No. 46307/66. Heading G5J. A musical box incorporates a sound amplifying core mechanically coupled to the plucked teeth. As shown, a spring-driven drum 22 has pins which pluck the teeth of a comb which is supported on rubber or other soft pad 42 to prevent vibrations from being transmitted to the casing. A plastics amplifying cone 16 has its vertex 50 adjacent the free end of a plate 44 supported in contact with the comb and adapted to transmit the vibrations. A control knob 58 may be used to rotate a lever 54 so as to interpose a wedge 48 partially or completely between the free end of the plate 44 and the vertex 50. This gives a variable degree of mechanical coupling and thus a variable amplification. In modifications (Figs. 6 and 7, not shown) the plate 44, which may be bent to U-form, is in direct contact with the vertex and the volume control is eliminated.

[Also in Division G1] A probe for measuring the true temperature of a surface comprises a pair of thermocouples with one element in common and a heater element. One of the couples is disposed adjacent the surface while the other is placed so that a temperature difference between the couples indicates heat flow into the probe from the surface. In operation any such temperature difference causes the heater to be energized to reduce it, and hence the heat flow, to zero. Typically the probe comprises a ceramic rod 100 (Fig. 4) with a flat contact area 101 carried on necked portion 104, and has a platinum strip heater 102 insulated from the thermocouple assembly by a mica plate 119. The thermocouple assembly consists of insulated chromel and "Alumel" (Trade Mark) wires which are joined at their flattened terminal portions beneath ceramic spacer 113 to form one couple. The end of the Alumel wire extends through a hole in the spacer to be welded to the overlying flattened central portion 116 of chromel wire 115 to form the second couple.

The T- shaped platinum member 134, the head of which contacts the surface, forms thermocouples with platinum rhodium wires 138 and 139, with platinum wire 140 forming an output lead. In operation the couples are connected in series opposition to the heater control circuit while the output of one couple is fed to a temperature indicator.
