Title: Improvements in electric dry batteries
IPC: H01M4/06
Filed: 1946-01-25
Abstract: 607,099. Batteries. BURNDEPT, Ltd., RICHARDSON, R. P., LEWIS, R. W., and ROWE, L. R. Jan. 25, 1946, No. 2543. [Class 53] A cell of the layer type as described, for example, in Specification 579,986 is provided with an auxiliary negative electrode which is perforated and separated from but electrically connected to the main electrode. In the form shown in Fig. 1, the auxiliary electrode 5 rests on the rounded corners of the main negative electrode formed by the cup 1. The space 14 between the two electrodes may be filled with absorbent material or left empty to receive electrolyte which percolates into the space when electrolyte is poured into the cell. In a modification, the electrode 5 is corrugated or provided with pressed ribs to space it from the bottom of the cup 1. In a further modification, the perforations in the electrode are formed by pressing out tongues which also serve to separate the two electrodes. Slots may be pressed out in the same way so that the auxiliary electrode takes the form of a louvre. The auxiliary electrode may also comprise a wire wound into a flat spiral or bent into grid form with feet 11 as shown in Fig. 6. The spiral type of electrode or an electrode consisting of a perforated plane sheet may be separated from the main electrode by forming the latter with pressed-up ribs 13 as shown in Fig. 7.

Abstract: 1,189,593. Toothed gearing. F. DURAND. 17 Jan., 1968 [30 Jan., 1967], No. 2650/68. Heading F2Q. To ensure correct meshing between an internally toothed gear 1 and a driving pinion 3, the latter is mounted in a floating case 4 connected by respective links 7, 8 to two fixed points one on either side of the plane X-X containing the pinion axis O 1  and the gear axis O 2 , each link lying substantially in the median plane of the pinion teeth and forming with the plane X-X an angle α approximately complementary to the pressure angle of the teeth, the link 7 being connected by universal joints 5, 9 to one fixed point and to the case 4, while the link 8 is connected by a universal joint 6 to the other fixed point, and by means preventing relative pivotal movement between the link 8 and the case 4 in the median plane of the pinion teeth to the case 4. As shown, said means is a pivot pin 10 lying in the median plane. In Fig. 3 (not shown), the means is two universal joints (10a having their centres in the median plane. The fixed points are on a frame member 15. In Fig. 1, the universal joint 5 connects the link 7 to an eccentric 11 which is rotatable to disengage the pinion 3 from the gear 1. In Fig. 3 (not shown), the link (7a) is telescopic, its length being controlled hydraulically or by other means to engage or disengage the pinion (3a) and the gear (1a).

Title: Improvements in and relating to television systems
IPC: H04N9/68
Filed: 1952-02-01
Abstract: 750,492. Automatic volume control. PHILCO CORPORATION. Feb. 1, 1952 [Feb. 2, 1951], No. 2764/52. Class 40 (4). [Also in Groups XL (b) and XL (c)] In a receiver for colour television signals of the dot-segmented type, undesired variations in the relative amplitudes of the high and low frequency components of the received video signal are connected by means responsive to the amplitude of the line synchronizing signals at the low-frequency end of the video band and the colour synchronizing bursts at the high-frequency end. Thus, as shown in a first embodiment, Fig. 1, the output of the second detector 11 following I.F. amplifier 10 is applied through a gate circuit opened only during the line blanking intervals to two band-pass filters 16, 17, the first selecting the 3.6 mc/s. synchronizing bursts which are located on the back portion of the line blanking pedestal and the second the 15.75 kc/s. line synchronizing pulses. A rectifier 19 develops a potential proportional to the amplitude of the synchronizing pulses and controls the gain of the I.F. amplifier to maintain the level of the whole video signal constant. A further rectifier 18 develops a potential proportional to the amplitude of the synchronizing bursts. At the output of detector 11 the video signal is divided by filters 12 and 13 into low- and high-frequency components corresponding respectively to the brightness signal and the 3.6 mc/s. modulated sub-carrier, and the potential from rectifier 18 is applied to control the gain of an amplifier 14 following filter 13 whereby the correct relative amplitudes are maintained for the two components. In a second embodiment, Fig. 2 (not shown), the output from rectifier 19 controls the I.F. amplifier as-before but the output from rectifier 18 controls a reactance tube circuit shunting a channel conveying the whole of the video signal so as to modify the high-frequency response of the channel and maintain the desired amplitude relationships.

Abstract: 1,240,094. Moulding concrete blocks with through holes. BANBURY BUILDINGS Ltd. 20 Jan., 1970, No. 2789/70. Heading B5A. An article of concrete or similar material having at least one through hole is made in a mould 10 having at least one projection 11 perpendicular to the mould wall opposite its mouth, and a press-head 12 having resiliently retractable plungers 15 which engage the projections 11 when the press head is forced into the mould. Concrete 22 is placed in the mould until its level is above the outer end of projection 11 but does not cover the projection. The press-head comprising the three members 12, 13, 14 is forced downwards and compresses the concrete, while the plunger 15 is forced into the  cavity above itself against the pressure of spring 18 held in place by screwed bush 19. Bush 16 is provided with grooves which retain any concrete forced into the space between bush 16 and plunger 15. The press-head is then raised from the moulding and is replaced by a suction head fitted with a resilient surround which is shaped to seal the suction area from the holes which have been produced in the block. The suction head is then operated to remove the block from the mould.

[Class 135] A valve, particularly for automatically ventilating air from heat-radiators in rooms, comprises hygroscopic discs E alternately of wood and vulcanized fibre which are mounted on a slotted or bored rubber stem D and are clamped when moist by a screw B to prevent escape of water through apertures F. If the water-level in the valve, which is secured horizontally to the head of the radiator, is depressed by accumulated air the discs E dry and allow its escape at F. The valve C, which permits passage of water along its screw-threads, is closed when the discs E require replacement. The Specification as open to inspection under Sect. 91 comprises also a modification in which the discs E are threaded on a squared extension of the valve C, which extension co-operates with a recess in the screw B. This subject-matter does not appear in the Specification as accepted.

Feb. 7, 1924 Seaming.-In a machine for seaming sheetmetal receptacles as described in Specification 211,175, the contacting parts of the end and body are folded one over the other, these parts are then flanged, bent towards the body and finally flattened. A body x, with flanged and dished ends y, is clamped against a chuck a<2> by a chuck b<2> which is moved axially by a lever d<4>, rod d<3>, rack gear d<2>, d<1>, and a hand lever d which causes the chuck to revolve as described in the prior Specification. The rod d<3> is locked in its work clamping position by a spring catch d<6> which is withdrawn, to release the work and stop the rotation, by hand or by a cam D on a spindle e<5>. During one revolution of the spindle e<5>, cams f, f<1> thereon move levers f<2>, f<3>, rods f<4>, f<5>, levers g<2>, g<3>, and rods g<4>, g<5> which are connected to the holders j, i<4> of grooved and flat seaming rollers h, h<1>. The holder i<4> is also connected to a lever i<9> pivoted to an adjustable guide block i and adapted to engage a pin j<2> in the holder j so that vertical movement of the roller h<1> results in horizontal movement of the roller h. The cams f, f<1> are so shaped that the roller h is first advanced, I, Fig. 5, to curl over the projecting flange of the end y, a spring bolt j<5>, Fig. 3, falling behind a projection j<4> to hold the roller h in position horizontally while the roller h<1> moves up, II Fig. 5, and the roller h moves down to flange over the seam.
