[Also in Division B5] A cable of twistor wires 11 or other wires or filaments which have to be accurately located with respect to each other and embedded in a thermoplastic Jayer 12, 13, is made by feeding the wires over a grooved roller, the grooves being shaped to grip each wire at two points spaced apart on its peripheral surface and to expose over 180 degrees of that surface, bringing the thus held wires into engagement with a heatsoftened thermoplastic layer 12, which is supported on a sheet 14, so that the thermoplastic material will flow around the wires, cooling to set the assembly, and bringing it into engagement with a second heat-softened thermoplastic layer 13, supported on a sheet 16, to form the bonded assembly shown. Apparatus for effecting the method is described (see Division B5). The thermoplastic layer may be polyethylene and the supporting sheet may be thermosetting or of " Mylar " (Trade Mark).

Title: Improvements relating to prepayment gas meters
Inventor: MOORE JOHN ALEXANDER
IPC: G07F15/00
Filed: 1948-02-03
Abstract: 648,408. Prepayment gas meters. GLOVER & CO., Ltd., G. Feb. 3, 1948, Nos. 3093 and 6281. [Class 27] [Also in Group XXIX] A prepayment gas meter has a pair of outlets, one e of which is controlled by the auto-valve j, whilst the other f is in permanent communication with the metering mechanism. This second outlet f is for connection to refrigerators or similar apparatus which require an uninterrupted but small supply, and delivery through it is restricted by a small opening k. The quantity mechanism comprises a screw and nut m, n arranged to traverse a slide p in opposite directions during prepayment and consumption. The mechanism is shown in credit, a pin q on the slide holding a spring-loaded lever r connected to the valve j in a position to hold the valve open. When credit is exhausted, the pin q passes a step in the lever r allowing it to rock under the action of its spring s to close the valve. The pin q then moves slowly across the right-hand half of the lever r, as gas is delivered through the outlet f. When a further prepayment is made the pin q must be returned beyond the step in the lever r before the valve j is opened to restore the main supply through the outlet e. In this way payment is secured for all gas delivered through the outlet f. In the modified mechanism of Fig. 2, (not shown), the nut n is connected to the valve j by way of a slidable rod, a compression spring between the nut and rod yielding during restricted consumption through the outlet f after the valve has closed.

Title: Improvements relating to electrically operated devices for controlling or regulating the level of liquid or other flowing materials
IPC: G05D9/12
Filed: 1933-02-01
Abstract: 410,278. Regulating liquid levels. EVERSHED & VIGNOLES, Ltd., and NEEDHAM, J. C., Acton Lane Works, Chiswick, London. Feb. 1, 1933, No. 3120. [Class 123 (i).] The level of liquid or other flowing material in a tank 1 is regulated between two levels by means of a nickel wire resistance element 2 at the high level, and a similar element 3 at the low level. These elements are connected in parallel in the circuit of an electromagnetic switch 6 controlling a motor starter 7 connected to the motor 8 of a pump 9. When the tank is full, both elements are submerged and cooled, and offer low-resistance paths in parallel, so that the contact 11, 12 is broken. When the resistance 2 is exposed, its temperature and resistance are increased, but the current is still sufficient to keep the contact 11, 12 open. When the resistance 3 is exposed, the current is further reduced, and the contacts 11, 12 are closed so that the pump is started. The level in the tank then rises until the contact 2 is submerged. The arrangement may be reversed so that the pump withdraws liquid from the tank. Specification 409,102 is referred to.

Title: Improvements in electrical impulse generators
IPC: H03K5/01
Filed: 1939-11-10
Abstract: 538,221. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., BARNARD, R. M., and KRAM, W. Nov. 10, 1939, No. 3619/41. Divided out of 537,142. [Class 40 (v)] Rectangular pulses are generated by a form of relaxation oscillator in which a pentode having a steep anode-current grid-voltage characteristic and a small saturation current controls the initiation and/or termination of the impulses (i.e. the duration of the pulse), while a condenser-resistance combination determines the frequency of impulse-repetition. Control potentials of any form may be applied at N1, N2 but the circuit is self-exciting, the pulsefrequency being controlled by the resistance Rand condenser C connected in the feed-back circuit from the anode of V2 to the grid of V1, the characteristic being given in Fig. 2 (not shown). The duration of the pulse is determined by the potentials applied to the electrodes of V1, which control the saturation current of V1 and hence the maximum potential applied to condenser C. A positive pulse applied to the grid of VI decreases the potential on the grid of V2 thereby decreasing the current in V2 to initiate the pulse in the output circuit of V2. The pulse in the anode circuit of V2 also charges the condenser C positively, so that the grid of V1 is made more positive and the current in V1 rises quickly to its saturation value. The grid potential of V2 and consequently the charge on C then commence to fall and the potential on the grid of V1 will fall likewise. Where the potential on the grid of V1 falls past the upper bend of its characteristic, the current through V1 decreases so that a negative charge is applied to condenser C, the process being cumulative so that the anode current in V1 falls rapidly, and the rectangular. impulse in the anode circuit of V2 is terminated.
