Filed: 1925-04-17
Abstract: 232,622. Norman, W. R. Feb. 17, 1925, [Convention date]. Vehicle lamps; lighting, systems of.- A road vehicle is provided with meam for switching on a lamp 1 mounted on the windscreen to illuminate one side of the vehicle and the road at that side to the front and rear of it, and for simultaneously dimming the head-lights. The lamp 1 comprises a reflector 25 of oval cross-section, an axially adjustable electric lamp-holder 26, and a front glass 31 held in position by a hood 30. The lamp 1 may be connected, as shown in Fig. 4, by a wire 18 and a switch 17 to a wire 15, connected to the headlights and, through a switch 14, to a wire 13 leading from a generator. A storage battery may be connected to a switch adapted to operate bulbs of the headlights or the dim bulbs and the lamp 1. A resistance 23 for dimming the headlights may be brought into circuit when the lamp 1 is operated by a switch 21 connected to a storage battery. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the lamp 1 may be provided in the rear portion of a headlight.

Title: Improvements in the sharpening of rock drilling bits having chisel-shaped cutting formations
IPC: B24B3/33
Filed: 1950-04-24
Abstract: 668,919. Grinding rock drills. BOART PRODUCTS (SOUTH AFRICA), Ltd., and IMPREGNATED DIAMOND PRODUCTS, Ltd. April 24, 1950 [April 28, 1949; Sept. 2, 1949], No. 10084/50. Class 60. Apparatus for sharpening a chiselshaped rock drill 4 consists of a rotating grinding wheel 5 of V-shaped profile, a clamp 3 to grip the drill, means to bring the drill and the wheel into contact and to permit relative oscillation between them about an axis intersecting the drill axis and parallel to the wheel axis. The clamp 3 comprises a fixed jaw 8 and a movable jaw 8a operated by a hand lever 9 through pivoted links 10. The jaws are shaped to fit the drill shank and the clamp is secured to one element of a bearing pair to permit the drill to be oscillated manually between the positions determined by two adjustable stops 46, 47. A carriage 11, which supports the clamp and is mounted on guideways in a bed 12, is fed towards the wheel 5 by a weight 14 until an adjustable stop 22 on the carriage engages a bolt 23b of a dashpot 24. The latter retards the carriage before the drill comes into contact with the wheel and its rate of yield is governed by the setting of the bolt 23b. A rotary air motor drives the wheel 5 through a dog clutch. The wheel is slidably mounted on its shaft and is enclosed by a casing 30 fitted with pipes 42, 43 for the supply and recovery of liquid. To set the cutting edge of the drill at the correct distance from the axis of oscillation, the carriage 11 is held by a manually-operated, spring-loaded pawl 18 while the shank of the drill is adjusted in the clamp 3 until the cutting edge is in contact with an adjustable stop 28. The latter is carried by a lever pivotally mounted on the casing so that it may be swung out of the path of the drill. If drills with hard metal inserts are to be treated, the grinding wheel may be wide enough to grind only the insert itself ; the remainder of the drill head is ground, if desired, by other means.

Title: Improvements in spring-dropper jacquards
IPC: D03C3/24
Filed: 1923-04-14
Abstract: 217,693. Jardine, Sir E., Jones, F. H. Haslam-, and Swindall, J. W. April 14, 1923. Jacquards.-In a spring dropper Jacquard, the driving bars B, B<1> are secured to carriages C, C<1> sliding on shafts D and actuated by blocks L, M on three-armed levers F<1> - - F<3> and G<1> - - G<3>, controlled by cams and counter-cams on a shaft J.

Pairs of shafts Q, R carried by bearings f, f<1>, g, g' on the arms f<1>, G<1> are reciprocated along these oscillating arms by lever mechanism U, V, V<1> controlled bv cams on the shaft J. These shafts carry bearings for the card prisms, which are rotated, after they have descended, and during the subsequent oscillating movement of the driving levers, by the engagement of pinions on the prisms with fixed segmental toothed racks. The dropper cages O, O<1> are carried by the driving levers, and the droppers are prevented from jumping out of them by readily-removable bars n preferably of vulcanized fibre forming a grid above the stocks of the droppers.

Patent GB-170605-A (GB)
Title: Improvements in radio telegraphy signaling systems
IPC: H04L27/04
Filed: 1920-04-12
Abstract: 170,605. Jackson, W. J. Mellersh-, (Taylor, A.). April 12, 1920. Keying systems and apparatus.-In an arc transmitting-system, the arc is placed directly in the aerial circuit, and signals are produced by keying a circuit containing resistance or other energy-consuming element placed in shunt across part of the aerial inductance. The key may also control means for re-igniting the arc. The energyconsuming element may comprise an iron core, which is magnetically saturated when the key is closed and produces hysteresis loss in the shunt circuit. The saturating-coil may be connected to an alternating-current source, thus producing a group frequency. In the arrangement shown in Fig. 2, the arc 2 is supplied by a generator 5 through a choke coil 6, and a magnetic field is maintained across the arc by magnets 8 energized by a source 9. The arc is connected between the aerial 3 and earth. Signalling is effected by pressing a key 13 which, when on its back stop, closes a shunt circuit across part of the aerial inductance 4. The shunt circuit includes a resistance 12 preferably equal in value to the impedance of the shunted portion of the coil 4 at the operating frequency. The resistance when in circuit reduces the aerial current to below signalling value, but pressure on the key 13 opens the shunt circuit, and full current is delivered to the aerial. If the current is reduced sufficiently to extinguish the arc, the key 13 may be arranged to close the circuit of an alternator 18 connected through a transformer 15 to a spark-gap 14, the surge of current occurring on the breakdown of the gap serving to re-ignite the arc. A modification is shown in Fig. 4, in which the resistance 12 is replaced by a coil 24 wound on an iron core 23. The signalling-key 27 is connected in series with an alternating or direct current source 68 and with a second coil 25 wound on the core 23. The current from the source 68 varies the saturation of the core 23 and thus varies the hysteresis loss in the circuit 22. If a direct-current source 68 is used, the aerial emits continuous waves during signalling, whereas if the source 68 is alternating, groups of waves are radiated. Choke coils 28 prevent high-frequency current from circulating in the key circuit. Specification 142,141 is referred to.

Abstract: 644,940. Automatic frequency control systems. MARCONI'S WIRELESSS TELEGRAPH CO., Ltd. April 14, 1948, No. 10411. [Class 38 (iv)] [Also in Group XL (c)] A controllable reactance valve circuit, for use in frequency-modulation or in automatic frequency control of very high radio frequencies, comprises a valve VI, Fig. 1, with a reactor X in its cathode lead, the mutual conductance of the valve being varied by a control voltage applied to its grid CG1 so as to produce the effect of a varying resistance shunting the reactor X, this combination being connected through an impedance-transforming line or network TL across the tuned circuit LK whose frequency is to be varied. The length and characteristic impedance of the line TL are so chosen as to convert the fixed reactance X at the input end to a fixed resistance across the tuned circuit LK, and the variable resistance due to the valve V1. into a variable reactance. The valve V2 maintains oscillations in the circuit LK by back coupling, and the anodes of both valves, V1, V2 are earthed for radio frequencies by the condenser K1. The impedance-transforming line TL may be replaced by a network with lumped impedances (Figs. 4 and 5, not shown). The reactance X may be constituted or supplemented by the inherent cathode-earth capacity ; and when the network TL includes a series condenser, the cathode may be connected to earth by an inductance coil. Both valves V1, V2 may be replaced by push-pull pairs, the network then being balanced about earth (Fig. 6, not shown).
