Abstract: 1,259,649. Bracelets. Bracelon (Birmingham) Ltd. 4 March, 1969, No. 11455/69. Heading A3H. A substantially circular bracelet comprising two semi circular parts hinged together and having a fastening device consisting of a headed projection 9 on one free face fitting into a keyhole shaped cut out 6 on the other free face, to engage and disengage head 10 with portion 7 of the keyhole aperture, when the two parts of the bracelet are resiliently deformed from their unstressed condition in a direction at right angles to the plane containing the two parts. The keyhole cut out may be cut parallel to or at right angles to the axis through the bracelet, or may be cut so that the head of the keyhole shape is cut into the wall 2 rather than the face.

In a flash-bulb of the percussibly ignitable type the priming substance 6 is enclosed in the deformed section B of a metal tube 4 protruding from and in communication with the interior of the bulb 1. The deformation of the tube is such that it is either flattened to a conical form or to a rectangular cross-section wedge shaped form with the smallest dimension at the end farthest from the bulb so that a smaller firing force is required than would be the case for the undeformed tube. The priming substance 6 may be in the form of a percussion cap as shown, or may be enclosed in a plastics or metal capsule, Fig. 4 (not shown), when it may be mounted on a support gripped between the walls of the tube, Figs. 5-7 (not shown). Otherwise the priming substance may be in the form of powder filling the deformed portion of the tube and retained therein by a plug, Fig. 3 (not shown).

Abstract: 1,267,075. Automatic voltage control. ROBERT BOSCH G.m.b.H. May 9, 1969 [May 10, 1968(2)], No.23650/69. Heading G3R. An automatic voltage regulator for a variablespeed three phase alternator 11 having a rectified output 12, comprises a switching transistor 41 which intermittently energizes the alternator field winding 24 and is controlled by an amplifier 19 formed from a differential transistor amplifier 43, 44 whose outputs are symmetrically loaded by a pre-amplifier including a pair of complementary transistors 46, 47 and whose inputs are derived from voltage dividers 15, 16 connected across the output of auxiliary rectifiers 37, 38, 39 also supplying the regulator components and field winding 24. The dividers include non-linear reference diodes 53, 63 chosen to produce, at the differential amplifier inputs 82, 86, voltages U1, U2 which have oppositely-shaped characteristics over the range of rectified output voltage U L  so that these characteristics intersect at a point corresponding to the desired voltage at which regulation is to occur, Fig. (not shown). Below this voltage transistors 43, 44 are respectively blocked and conductive to render transistors 46, 47, 42 conductive and hence energize the winding 24 through the transistor 41. Switching off occurs when both transistors 43, 44 are conductive at the desired voltage, the switching action being accelerated by a feedback resistor 72 connected between the driver transistor 42 and the divider 15. To prevent resonance-produced oscillations arising from the winding inductance and switching capacitances, the transistor 46 is arranged to have an amplification factor dependent on frequency, by forming this transistor from two inter-connected transistors, Fig. (not shown) respectively having a low and a high current amplification to produce a low cut-off frequency. The function of certain circuit components, particularly the resistors 76, 77, is discussed in detail and alternative voltage divider arrangements are disclosed, Fig.5 (not shown), some of which include two or more series-aiding or series-opposed diodes. Thus the level and temperature dependence of the regulated voltage are determined by the divider characteristics.

The microswitch (25) is associated with an actuating plate (22) coacting with the mandrel 19 of the roll supported on the winding rolls 6 (Fig. 3, not shown). The core magazine is laterally adjustable to receive and retain cores having a length commensurate with the width of the fabric to be wound (Fig. 1, not shown). The continuously supplied fabric passes over a driven draw roll 43 on its way to the apparatus, and forms into a loop 44 when the rolls 6 are stopped for the rolldischarge and web-severing operations.

Abstract: 1290597 Transistor amplifying and gating circuits; phase detectors; gain control SONY CORP 24 April 1970 [1 May 1969] 19817/70 Headings H3A H3T and H4R A transistor circuit comprises a pair of transistors Q1, Q2, having first, second and third electrodes, at least one of the first electrodes being supplied with an input signal, means for deriving an output signal from at least one of the second electrodes, and means, i.e. transistors X1, X2 connected with the third electrodes for producing a constant current. It is characterized in that a pair of diodes D1, D2 are provided to constitute a series connection between the third electrodes and that semi-conductor control means, i.e. transistor 1, is connected between the pair of diodes to give switching operation to the pair of diodes with a control signal. In the embodiment, signals are applied in opposite phase to the bases of both transistors Q1, Q2 and are taken from both collectors by means of load resistors R1, R2. Resistors r1, r2 are connected in series with diodes D1, D2, and a resistor 6 is common to the emitter circuits of transistors X1, X2. In a modification (Fig. 4, not shown) this resistor is replaced by the collector to emitter path of a further transistor (X3) and the transistor 1 is replaced by a pair of parallelconnected transistors (21, 22). The transistors Q1, Q2 may drive a further pair of transistors in long-tailed pair connection (Fig. 3, not shown). The arrangement may be used as a gating circuit, the gating signal being applied to the base of transistor 1, as an automatic gain control circuit, applying the a.g.c. voltage to the base of transistor 1 and the diodes D1, D2 acting as variable impedances, as a synchronous detector, or as a phase detector. It may alternatively use field-effect transistors.

The passages extend radially inwardly beyond the external surfaces engaged by the friction members, the low melting point material contained in said passages being a metal or alloy also having a low vaporization point and, the metal or alloy in each passage, when solid, occupying less than half the volume of each said passage, so that, when the metal or alloy is melted by heat generated by friction in the brake, thrown outward by centrifugal force, and vaporized by further heating, the vapour can return radially inwardly along the passages, condense at the cooler inner portion of the disc, and return to the outer peripheral portion in liquid form to provide continuous absorption of heat by repeated vaporization. As shown, the disc 26 comprises plates 30, 32 moulded from sintered metal one or both of which is or are, provided with grooves 36 which, when the plates are assembled together, form radial passages 42. Each passage has introduced therein a metal, such as sodium, of low melting and vaporization point in molten or solid form.

The solenoid includes a plunger-type armature which is drawn into within the confines of the solenoid windings when the latter is energized. A lever D is detachably secured to both the solenoid and the closure member by the provision on these of grooves 102, 44, respectively, which are embraced by U-shaped terminal portions 122, 126 of the lever, these portions being depicted in detail in Fig. 1, not shown. Intermediate its ends, the lever is contained within a reduced portion 138 of an adjustable fulcrum member 130, and intermediate the fulcrum and the terminal portion 126 the lever has attached thereto the terminal portions of the two springs 166. In the de-energized state of the solenoid, shown, the springs act upon the lever to cause it to move in a clockwise direction and so the closure member 30 is moved into engagement with its seat 26 and the armature 100 is moved outwardly of the solenoid. Conversely, on energization of the solenoid, the lever is caused to move in an anti-clockwise direction and so the valve is opened. The valve member is sealed relative to the valve housing by a flexible diaphragm 50. A double bracket 60, 70 engages the valve housing and is rendered rigid by a pair of screws 74, the screws extending sufficiently for to ensure a secure connection between the bracket arrangement and the solenoid carrying bracket 116. The fulcrum member is contained within a groove 142 of a web 140 clamped by the two screws against the bracket arrangement and is movable within the groove by adjustment of a screw 154.
