Patent GB-1527454-A (GB)
Title: Safety alarm system
IPC: H04B1/40
Filed: 1977-04-07
Abstract: Each transmitter of the security alarm system can be accommodated in a housing of a wristwatch and exhibits a crystal oscillator, the radio-frequency signal of which is modulated by an audio frequency supplied by an oscillator with piezo-electric resonator. This audio frequency forms a code signal. In the case of a threat, the person carrying the transmitter triggers the alarm and the modulated radio-frequency signal is radiated via an antenna. A receiver which is installed, for example, in a building, responds only to particular code signals. For this purpose, it exhibits an antenna, a receiving section for reception, amplification, mixing and demodulation of the modulated radio-frequency signal. The audio frequency at the output of the receiving section is supplied to a number of decoders each provided with a piezoelectric resonator as receiving filter and with an evaluating circuit so that the threatened person from which the alarm originates can be accurately determined.

Abstract: 975,828. Mounting electrical equipment. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 25, 1962 [April 25, 1961], No. 14954/61. Heading H1R. In a mounting arrangement for insulating cards carrying printed wiring on one side and small circuit components on the other, a plurality of cards are mounted in the same plane by insertion into longitudinal slots in support members which are mounted on frame members, it being possible to mount the support members on the frame members at different spacings so as to accommodate cards of different sizes. As shown, Fig. 1, a moulding 3 comprises longitudinal slots 4, 5, which receive edges of printed circuit cards 1, 2 and a channel 6, one edge of which is given slots 7 for fanning out the wiring, while the other edge has three larger slots 8, 9, 10 which extend through the moulding, Fig. 3, so that wires from cable forms 11 may pass from one side of the cards to the other. Wires pass from slots 7 through holes 12 in the cards and are soldered at 13 to the printed wiring; alternatively, the wires may be soldered to tags which pass through the cards and contact the printed wiring on the other side. In a modification, Fig. 8, both edges of the channel 31 have small slots 32, the larger slots being replaced by holes 33, in the bottom of the channel 32, through which wires pass from one side of the cards to the other, being guided by ridges 34.

Textile spindles 2 (see Fig. 1) are driven from a primary driving belt means 12 via an intermediate pulley or pulley assembly 6 and secondary belts 4 or 14. The secondary belts run in grooves 5, 15 while the primary belt engages the outer ends of the grooves. The pulley shaft 8 is adjustable in base 1 so that the tension in the secondary belts is adjustable. In a further similar form two primary belts are provided which engage in the same grooves as the secondary belts but are radially displaced therefrom. In Fig. 5, each pulley means 31 drives four spindles and alternate ones are displaced to be driven by one run of the primary belt while the remaining pulleys are driven by the opposite run of the primary belt. In further forms the intermediate pulley assembly comprises three pulleys fixed on a single shaft, the intermediate pulley engaging the primary belt while the secondary belts engage the outer pulleys and run to separate wharls on the same spindle or to different spindles. Three grooves formed in the same pulley may be similarly used. The belts may be flat or round or may have teeth or slots to engage teeth on the pulley means (see Figs. 6 and 7, not shown).

Abstract: 655,450. Winding and paying-out apparatus. HOPKINSON, A. June 8, 1949, No. 15226. [Class 78 (v)] In winding and paying-out apparatus of the type comprising one or more winding drums mounted on a cylindrical casing within which the driving unit is mounted, the transmission gearing between the driving unit and the or each drum includes a friction clutch which is coaxial with the drum and operated by an annular coaxial piston working within a fixed annular hydraulic cylinder to which hydraulic pressure is admitted to cause engagement of the clutch, so that the piston rotates within the cylinder when driving the drum. The prime mover B is fixed within a cylindrical casing A<1>, which is sectioned for assembly, and which supports two drums C, C<1>. The outer flange of each drum has an axially extending flange C<3> to which are splined driven clutch plates D, interposed between driving clutch plates D<1>, which are splined to the hub E of a gear-wheel El. Each gear El meshes with a pinion K on an idler shaft K<1> which also mounts a gear-wheel K<2>, in turn meshing with an idler gear L on a pin N, which meshes with a gear M secured by means of an internally splined sleeve M<1> on the shaft B<1> of the prime mover. Pin N is eccentrically carried by a cylindrical block N<1> which is rotatable in a housing in the casing A<1> and is provided with a pin N<2> engageable in two holes N<3> so as to retain pin N at one of two distances from gear M. Thus by changing the sizes of gears M and L and the position of pin N a change of gear ratio is effected. The annular piston G is normally pressed into annular cylinder F by springs G<1> mounted between the piston and gear-wheel E<1> and around pins H, which pins couple the piston to rotate with gear El and also transmit the movement of the piston G through holes in gear El to the clutch plates. When fluid pressure is admitted at J, the clutch plates D and D<1> are pressed into engagement.
