Patent GB-282159-A (GB)
Title: Improvements in or relating to electrical regulating or control systems for electric motors
IPC: H02P7/26
Filed: 1926-09-16
Abstract: 282,159. Smith, W. S., McLachlan, N. W., and Jacob, W. G. R. Sept. 16, 1926. Systems depending on two or more machines. -A motor driving a variable load is enabled to maintain a uniform speed by providing a second generator so coupled to the first through thermionic valves that it constitutes a compensating load which automatically increases when the useful load decreases, and vice versa. The invention is particularly applicable to telegraphic apparatus of the kind described in Specification 282,476, [Class 40 (iii), Telegraphs, Electric], in which received signals amplified by a valve 4 are applied to the field winding 5 of a generator 5, 11, which is driven by a motor 27. Variations in the load on the latter are equalized by opposite variations in the load of an additional generator 26 having an output impedance 31 and driven from the same shaft 51 at the same or a different speed. The generator 26 is coupled to the generator 11 through valves in such a way that the total load is constant. Thus a middle brush 17, Fig. 1, may be connected through the contact 21 to the filaments of a push-pull pair of valves 19, the brushes 10, 10 being respectively connected to the two grids 18, while the field winding 25 of the compensating generator 26 is in the common plate circuit. The valves 19 are normally at their rectifying points so that normally the generator 26 is supplied with a field by the winding 29 in series with the high-tension battery 28. When signals are received, however, one or other of the grids 18 becomes positive and plate current flows through the winding 25 whose field then opposes the field of the winding 29; thus the load due to the generator 26 is relieved when signals occur. In the arrangement shown in Fig. 2 the compensating generator 26 is controlled by the input valves 32 instead of by the generator 11, and in this case the winding 25 may (Fig. 3, not shown) be connected in the common plate circuit of a further push-pull pair of valves, the grids of which are respectively connected to the grids of the valves 32.

[Also in Group XXV] A machine for slotting screws comprises a cam 12 for axially-displacing a series of pins 11 for holding screws in slots in a drum 8a, 8b, and a radiallyadjustable broaching - device 3 for slotting the heads of the screws. The machine has two drums on opposite ends of a driven shaft, and two corresponding sets of tools 3. The screws travel from a container 7 along guiderails 4, and are deflected by a finger 5 into wedge-shaped slots 9 in a detachable disc 8b. The screws are held fast as they pass the tools by the resilient pins 11 engaging the fixed axiallyadjustable cam 12. The tools are mounted on a slide 17 adjustable axially of the drum on a swinging arm 18. A plough 20 removes the slotted screws from the drum, the movement of the screws pushing back the pins 11. A safety-device to ensure removal of all screws comprises a bevelled disc 23 which, if it contacts an irremovable screw, operates a stop-switch. The tools may be set by a gauge attached by magnets to the drum 8a, 8b.

Title: Method and apparatus for transmission of data
IPC: H04L13/08
Filed: 1965-06-01
Abstract: 1,103,965. Recoding information. L. E. RICHARDSON. 1 June, 1965 [17 Feb., 1965], No. 23318/65. Heading G4M. A card may have one or more conductive (e.g. pencil) marks in a column and is sensed column by column, and a binary number representing the row position of a mark is transmitted, together with a further bit indicating whether the next binary number to be transmitted represents the row position of a mark in the same column or the next column. The card described has 16 rows, the bottom row being reserved for an end-of-message mark. At the start, probes S1-S15 and SE, Fig. 2 (not shown), are in register with the respective ones of the 16 rows in the first column of the card. Clock pulses from a generator 118 advance counter 128 and produce relative movement in the column direction between the card and the probes. When probe S encounters the first mark, the contents of counter 128 are gated at 22 into a register 130, and if there are no further bits in the first column, NOR gate 120 enters a " 1 " into X register 130 to signify that the next number transmitted will relate to the next column, resets counter 128 and the generator 118 and causes relative movement by one column between the probes and the card. If there are two or more bits in a column, probe S gates out successive numbers as the marks are encountered, NOR gate 120 not producing an output until probe S encounters the last mark in the column. If a column does not contain a mark, gate 120 produces an output immediately, a " 1 " is entered in X register 130 and the Y registers 130 are not filled. The end of a message is indicated by a mark in the bottom row of the card and is detected by probe SE to cause generator 134 to enter a special character in registers 130. Each input to OR gate 124 causes transmission of the contents of registers 130.

Title: Improvements in and relating to automatic steering apparatus
IPC: G05D1/02
Filed: 1922-08-29
Abstract: 198,275. British Thomson-Houston Co., Ltd., (General Electric Co.). Aug. 29, 1922. Steering and manoeuvring automatically ; steering, controlling from a distance. - In an automatic steering-gear for ships, a drag towed by a long drag line is used to operate a tiller directly or to control servo-motors of steering gears when the ship swings from its course. For direct steering, the drag 36 has its drag line 35, Fig. 7, connected to the ship at 35<1> and also to the tiller 11. In electric-hydraulic steering gears, the drag line 35, Fig. 1, is attached to an arm 37 and carries a contact arm 38 which is placed between two stationary contacts of a switch in the circuit of an electric servo-motor 41. This motor is geared down to a shaft which is screwed and carries a nut attached to a plate 46 whereby the latter can be moved backward or forward by the motor. Electric magnets 47, when energized, move with the plate 46 and are coupled by a rod 48 to the main control 30 at the same position as is the rod 28 of the telemotor control. The servo-motor has a hunting mechanism. The solenoid brake 54 is on when the magnets 47 are de-energized for hand control and is off when the automatic control is used, the circuit being controlled by a switch 62 near the helm. The motor has two windings, the direction of running being controlled by two selector contacts in the circuits of the contacts and closed or opened by the arm 38 on the drag link. Automatic movement of the rudder results in the telemotor gear moving the steering wheel 20 in sympathy and thus provides an indication to the helmsman of the rudder position. A pointer may also be attached to the arm 37 and a scale provided to show the angle between the drag line and keel line of the ship.

Title: Improvements in or relating to apparatus for collecting and discharging water from compressed air or gas pipes
IPC: F16T1/26
Filed: 1919-09-26
Abstract: 138,292. Ogden, J. E. L. Sept. 26, 1919. Mains and pipes.-In apparatus of the bucket float type for drawing water from compressed air, gas, &c. pipes or mains, the inlet connexion of the trap is disposed below the top of the bucket so that the drain water floods the inlet connexion forming a water seal before it can enter the bucket; a leak is provided in the top of the trap so that the pressure is gradually reduced allowing the water to enter the bucket and to be discharged at intervals. In the form of apparatus shown in Fig. 1, the leak is provided by a nick 15 in a valve 13 closing a passage 12 leading from the top of the trap, above the bucket, to the discharge connexion 3 which is open to the atmosphere. The flow of water into the bucket 4, consequent on the reduction of pressure through the leak, actuates a valve 9 on a rod 10 secured to the bucket and moving within a dip pipe 5, allowing the contents of the bucket to be discharged. By unscrewing the valve 13, any obstruction will be blown away. The volume of air enclosed in the trap is diminished, and the rate of pressure reduction increased, by providing a displacement block 18 on the dip-pipe. In a modification, the valve-controlled passage 12 may be replaced by an open passage leading from the top of the trap into the interior of the dip-pipe, leakage taking place by a groove in the valve seat 6; the displacement block is integral with the cover of the trap, the dip-pipe being screwed into it.

Abstract: 918,851. Tempering glass. COMPAGNIE DE SAINT-GOBAIN. July 10, 1959 [Aug. 8, 1958], No. 23849/59. Class 56. A tempered glass sheet, having " viewing part " which maintains a degree of transparency even if the remainder is shattered, is produced by heating a glass sheet to its tempering temperature and directing separated streams of cooling fluid on to its face, the streams which impinge on the area which is to form the viewing part being caused to trace on the face of the sheet closed curved paths which do not intersect, those which impinge on the remainder of the area trace closed curved paths each of which intersects the adjacent path or paths. Thus, as shown in Fig. 1, the tempering may be effected by air blast from nozzles 1 spaced at a distance 2 from each other in the viewing part which is greater, e.g. 30 mm., than the spacing elsewhere, e.g. 20 mm. If now the whole nozzle system is given a circular translatory movement with a diameter of 30 mm. the circles traced out by the nozzles in the viewing part will not intersect while those traced by the nozzles elsewhere will overlap and intersect the areas shown notched indicate the areas on which the cooling blast does not impinge-allowing a certain spread of the blast from the nozzles. In the form of tempering apparatus shown in Fig. 3 the sheet 5 is suspended from a carriage 3 and run on rails 4 between blowing chests 7 carrying nozzles 1 and moved on circular paths on cranks 12. A separate system, shown in Fig. 5, is used to produce the air blast in the viewing area. The necessary holes are provided in transverse pipes 15 secured to a vertical pipe fed from a tube 16 extending through the chest 7 and axially displaceable through a gland 20. A stop-valve 17, pressure-gauge 18 and safetyvalve 19 are provided.
