Title: Improvements in or relating to brake apparatus for road vehicles
IPC: F16D51/04
Filed: 1928-11-10
Abstract: 324,439. Thornycroft & Co., J. I., and Barford, V. G. Nov. 10, 1928. Band; blocks and shoes acting on drums. - To prevent the operating cam of an internal expanding brake from producing cross-drag on the ends of the band or shoes means such as links are interposed between the ends of the band or shoes and the cam which, together with the links, is capable of limited floating movement. An anchor bracket 5 secured to the wheel axle casing 3 of a vehicle carries a link 4<a> provided with pins 4b which serve to support the brake band 2 at its middle part. A plate 12 disposed between the bracket 5 and the casing 3 carries a bracket 11 with pivot pins 10, 10<a> from which depend a pair of links or arms 9, 9<a> arranged between the cam 7 and the ends of the band 2. The cam spindle 8 is also mounted in the bracket 11 and by reason of the fact that the plate 12 has freedom of movement between the parts 3, 5 the cam is free to float. Release springs 14, 14a, 16 extend from the band to the bracket 5 and between the ends of the band respectively. In applying the brake the pressure of the cam is transmitted to the ends of the band by the links 9, 9<a> which thus take any drag exerted by the cam in a radial direction.

Abstract: 661,037. Sets. WESTERN ELECTRIC CO., Inc. Dec. 21, 1948 [Dec. 22, 1947], No. 32950/48. Class 40 (iv). In a telephone set, equalisation of the currents in subscribers' loops of differing lengths is achieved by the inclusion of non-linear resistance elements, one of which 14 performs the primary equalization whilst another 31 protects the first from damage by excessive voltages and also co-operates to modify the degree of compensation. In Fig. 1, a tungsten filament lamp 14 is shunted by a varistor 31 and is in series with the microphone to compensate for the effects of different loop lengths on the transmitter. A thermistor 16 having a negative temperature coefficient is included in the envelope of the lamp and is connected in series with a non-inductive resistance 17 across the receiver 18, which is also shunted by the crash limiter 19. The dial contacts are guarded against radio interference by a quenching circuit comprising a condenser 8 and a resistance 9, and an induction coil 34 and a condenser 35 comprise the anti-sidetone balance. The transmitter uses stabilized carbon and the granules of either coal or quartz have a carbon surface deposited from methane gas. Suitable dimensions for an improved hand-set utilizing  such a transmitter and a ring armature receiver are included and Specification 435,130 is referred to.

Filed: 1927-12-10
Abstract: 282,090. Kommandit-Ges. Rosenthal & Co. Dec. 11, 1926, [Convention date]. Counting-apparatus; zeroizing-mechanism.-In a liquid-delivering apparatus wherein two measuring chambers are alternatively supplied and emptied by means of a single rotary valve bored in such a way that two different quantities may be delivered, a cam 30, Fig. 1, pinned to the valve spindle 16 has long and short lobes 31, 32 to give corresponding reciprocations to a spring- controlled rod 36 adapted to advance a ratchet wheel 39 through four steps or a single step. With the valve set for delivering the smaller volumes the shorter lobe 32 will be effective so that oscillation of the valve will register only the smaller deliveries. The .ratchet wheel is fast with a numeral drum 42, Fig. 3, and this in turn is geared with a total counter 45. The drum may be reset by first drawing outwards a knob 49 so as to disengage the drum from the counter and then rotating it to return the drum to zero. Forward rotation of the drum is prevented by the engagement of a spring pawl 50 with a fixed ratchet ring 51.

Title: Improvements in or relating to electric incandescent lamps and discharge apparatus
IPC: H01J9/32
Filed: 1936-12-10
Abstract: 486,872. Sealing leading-in wires into glass. ARCTURUS RADIO TUBE CO. Dec. 10, 1936, No. 33957. Convention date, Dec. 11, 1935. [Class 36] A stem assembly for electric incandescent lamps and discharge apparatus, comprises a tubular glass stem, a vitreous mass providing a wall forming a closure at one end of the stem and shaped by pressure normal to the wall, an exhaust tube connected to the wall and forming an opening therethrough, and one or more electric conductors sealed in the wall area between the exhaust tube and stem. The formation of the wall may be effected by supporting the electric conductors 10, Fig. 20, in apertures arranged in a circle in a member 9, and locating the stem tube 13 and exhausting tube 12 coaxially therewith, heat then being directed upon the lower end of the stem tube from adjacent gas burners, so that the stem tube collapses inwardly and the bottom of the exhausting tube is softened, whereupon a plunger 20, Fig. 22, within the member 9 is moved to press upwardly upon the softened glass while a downward pressure is exerted simultaneously upon the exhausting tube 12 by a compression head 44 on a lever 43. Subsequently a reduced heat is applied to the glass wall and a current of air blown down the exhausting tube to clear its lower end and depress the glass around its outlet aperture. The amount of glass forming the seal may be increased by forming a bead of glass upon some or all of the leading-in conductors, these beads being interfused by the application of heat accompanied by pressure from upwardly and downwardly moving compression members to form a fused wall, the surface of which is scalloped and thus increases the surface distance between the wires, as shown in Fig. 11. Alternatively, the mass of glass may be increased by making the exhausting tube of greater diameter, or providing a button of glass on its lower end. The operations may be carried out on a rotary machine around the circumference of which are mounted a series of rotary heads each provided with a pair of resiliently mounted jaws for engaging the flare of a stem tube, together with cam-actuated compression-members.

Abstract: 1,212,572. Automatic exchange systems. TELEFONBAU UND NORMALZEIT G.m.b.H. 17 July, 1968 [9 Aug., 1967; 26 Sept., 1967], No 34090/68. Heading H4K. An exchange employing T.D.M. speech transmission employs a connecting circuit (of the conference type) comprising demodulators, mixing amplifiers and modulators to allow a third subscriber to join in (in break in fashion) an existing connection between two subscribers, the period of actuation of the modulators of the stations involved in the existing connection being reduced when the third party joins in. As shown, each substation TA, TB or TC is connected to the multiplex highway by a separate modulator and demodulator. Each substation may have a four wire connection as shown for substation TC or may be a two-wire substation connected to its modulator and demodulator by a two to four-wire network as shown at TSA or TSB. During a normal call between, say, substations TA and TB, the modulator of one substation and the demodulator of the other substation are simultaneously actuated during one time slot and the demodulator of the one substation and the modulator of the other substation are simultaneously activated during a second time slot to provide a full duplex connection. If a subscriber at a third substation TC wishes to join in he presses a special key requesting the use of a connecting circuit KN. He is allotted two time slots X and Y in which his modulator " Mod C " and his demodulator " Dem C " are activated. The connecting circuit demodulates at Dem 3 the signals from his modulator and applies them to mixing amplifiers M1 and M2 associated with the other two substations TA and TB. The time slots U and V already in use for the connection between TA and TB are each divided into two i.e. into U<SP>1</SP> and U<SP>11</SP> and V<SP>1</SP> and V<SP>11</SP> and while the demodulators of the substations TA and TB are allowed to continue operating during their full time slots V and U respectively, operation of the modulators " Mod A " and " Mod B " is restricted to a first half U<SP>1</SP> and V<SP>1</SP> respectively of each of their time slots. In the connecting circuits modulators " Mod 1 " and " Mod 2 " associated with these two substations are enabled during the other halves U<SP>11</SP> and V<SP>11</SP> respectively of the time slots, and demodulators " Dem 1 " and "Dem 2 " operate during the first halves of the time slots. Each mixing amplifier receives speech signals from both the demodulators in the connecting circuit and associated with the other two stations, thus a full conference connection is established. The whole system is controlled by a central circulating store.
