IPC: B63G8/40
Filed: 1925-11-26
Abstract: 253,425. Kalin, F. Nov. 26, 1925. Diving-chambers; air locks and submarine escape chambers.-Apparatus for rescuing the crews of disabled submarine vessels comprises a diving-chamber A with propellers and steering gear, connected to a salvage ship by means of a cable 9, and having at the bow a cylindrical extension through which communication may be established with the submarine. The extension consists of three compartments B, C, D, of which the lower compartment D is detachable. The chamber A is provided with propellers 6, 7, electric motors 2, to which current is supplied through the cable 9, pumps 2a, windows 4 and a searchlight 5. At the bow an opening 13, closable by a cover, communicates with the compartment B of the extension, which is so connected to the chamber that it may be rotated about the longitudinal axis of the chamber bv means of a hand-wheel 30. The lowermost compartment D is open at the bottom and is provided round the lower end with a flange 21 of flexible material such as rubber adapted to fit around the hatch 26 of a submarine. The compartments B, C, D are separated by partitions 15, 18, having hatchways with covers. When the chamber has been worked into position and the extension adjusted so that the flange 21 fits round tho hatchway 26 of the submarine, valves 24, 16 in the partitions 18 and 15 respectively are opened, and the water in the compartments is pumped out through pipes 25<1>, 25<11> and a valve 23 in the wall 17 of the compartment C. The pressure of the external water then forces the flange 21 into close contact with the hull of the submarine and makes a watertight joint. The hatches in the partitions 15. 18 and the hatch 26 of the submarine are then opened and the crew pass into the diving chamber. A crane 29 is provided to facilitate rescue work. and a drill 28 driven through a flexible shaft from a motor 27 may be used to cut an opening in the submarine if necessary. If work has to be suspended. the ratches of the compartments are shut and the connection between the wall 17 of the compartment C and the wall 20 of the compartment D is removed, releasing the chamber A and leaving the compartment D attached to the submarine by the water pressure

Title: Machine tools
IPC: F16H61/02
Filed: 1974-07-05
Abstract: 1470244 Actuating devices I OAWI 5 July 1974 [6 July 1973] 30000/74 Heading B3B [Also in Division F2] A shaft coupled, e.g. to a rotary table of a machine tool is driven through gearing providing high and creep speeds by a stepping motor, and indexing means positively locates the shaft in a desired position on cessation of drive at the higher speed. The indexing means comprises toothed, interengaging members of which the teeth, corresponding in number to the number of steps executed by the motor in one revolution, are so shaped as to correct during their engagement any deviation, within the range between two steps of the motor, of the actual angular position of the shaft from its desired position. In one embodiment the stepping motor 11 drives a flange 19 connected by an elastic ring 20 to harmonic or strain-wave gearing comprising an elliptical cam 22 which, through a ball bearing 23, acts on the inner surface of a thin-walled steel sleeve 25 having external teeth 31 meshing with internal teeth 32 of a part 33. A clutch comprises a member 28 fast with the sleeve 25 and output shaft 37 and a member 29 connected to the motor shaft 12 by a diaphragm spring 30, both members having interengageable teeth 38 on their co-operating faces, and the indexing means, acting as a brake, comprises a fixed member 15 and a magnetically controllable member 16 connected to the part 33 by a diaphragm spring 36, both of these members also having teeth 38. When, as in the lower half of the figure, the clutch is engaged and the brake released direct drive is established and on stoppage of the motor the brake is engaged to locate the output shaft. Release of the clutch and engagement of the brake, as in the upper half of the figure, establishes creep speed by interaction between the teeth 31, 32 as the sleeve 25 is deformed and rolled inside the part 33 by the cam 22. Again, on cessation of movement, the output shaft may be located by engagement of the clutch. The output shaft may be locked by simultaneous engagement of the clutch and brake. In a modification, employing a sun-wheel on the motor shaft and planetary spur wheels in mesh with the sunwheel and with an internally toothed ring and mounted on a carrier fixed to the output shaft, a clutch connects the ring with the motor shaft to lock up the planetary train for direct drive and a brake holds the ring for creep speed.

Title: Improvements in and relating to the rot-proofing of textiles, paper and other fibrous materials
Filed: 1936-11-05
Abstract: Fibrous materials such as fibres, slivers, rovings, threads, yarns, woven, knitted or netted fabrics of cotton, jute, flax, sisal, phormium tenax, ramie, silk or rayon, paper, paper pulp or paper boards, fibre or fibre boards, are simultaneously rot-proofed and sized by treating them with a metallic salt or ester of naphthenic acid or a mixture thereof dispersed in an aqueous vehicle which will not coagulate the sizing liquid, e.g. a rosin-wax size.  In a modification, the materials are treated with an aqueous dispersion of the rot-proofing agent prior to sizing. Suitable rot-proofing agents are aluminium and zinc naphthenates. In sizing paper zinc naphthenate in the form of a plastic solid is mixed with the molten sizing materials from which an aqueous liquor is then made.  Alternately, the naphthenate is dispersed in water by means of an alkali such as ammonia, the paper impregnated therewith and subsequently sized. Textile materials may be oiled after rot-proofing and agent such as rubber latex comprising vulcanizing agents and accelerators or a vulcanized latex may be used.  Specification 244,947, [Class 121], is referred to.

Patent GB-701950-A (GB)
Title: Improvements in electric temperature and flame-failure control systems for fluid-fuel burning heaters
Inventor: MAIN ROBERT COURTENAY
IPC: F24H9/20
Filed: 1951-12-28
Abstract: 701,950. Automatic temperature control. ROBERTSHAW-FULTON CONTROLS CO. Dec. 28, 1951, No. 30373/51. Class 38 (4). [Also in Group XI] An automatic temperature control system for a fluid fuel burner is also provided with a flame failure control and automatic igniter. The two controls act on two grids of a thyratron in the fuel-valve-solenoid circuit. The circuit is not self-cycling, and locks out on flame failure. The arrangement comprises a main burner 10, and solenoid controlled fuel valve 24, and associated temperature responsive bimetal switch 66 ; pilot burner 18, and associated temperature responsive resister 56, and igniter 22 (controlled through a time-delay circuit 78). A thermal overload cutout 54 is included in the heater transformer primary circuit. To start up the main fuel valve 14 is opened, and the supply switch 16 (linked to the valve) is closed ; igniter 22 lights the pilot burner 18 ; thermal delay switch 94 operates to energize relay 82 which breaks the igniter circuit at contact 86 and at contact 84 de-energizes the thermal delay switch, completes a self-holding circuit and completes the thyratron anode supply. As soon as the pilot burner has heated the temperature sensitive resistor 56 to reduce the bias on the shield grid 36 the thyratron conducts, energizing the solenoid 26 to open the main burner fuel valve 24. At the required ambient temperature thermostat 66 closes its contacts to apply a blocking bias to the control grid 34, thereby de-energizing the fuel valve solenoid. The system then cycles around this temperature. In event of flame failure resistor 56 cools, and the shield grid is biased to cut off thereby shutting off the fuel. The supply switch has to be opened to release relay 82 in the time delay circuit before the igniter can be re-energized. In an alternative arrangement, Fig. 2 (not shown), the thermostat is replaced by a temperature sensitive resistor.

Title: Improvements in or relating to methods of, and apparatus for, producing semi-conductor material
IPC: G05D23/27
Filed: 1961-08-25
Abstract: 913,427. Photo-electric control systems. SIEMENS & HALSKE A.G. Aug. 25, 1961 [Aug. 25, 1960], No. 30755/61. Class 40 (3). In the production of semi-conductor material, such as silicon with trace impurities, a carrier rod of silicon is mounted in a quartz chamber and heated to a temperature of 1100‹ C. by the passage of direct current. A suitable reaction gas is fed into the chamber and silicon semi-conductor deposited on the heated carrier either in mono-crystalline form or polycrystalline form. As the cross-sectional area of the rod increases its temperature would tend to fall if the heating current remained constant. To maintain the rod temperature substantially constant it is proposed to monitor the size of the rod photo-electrically and to effect a control of the heating current in accordance with it. As shown, the chamber 1 has a flat window 2 and an image of the rod 3 is formed at 9 by lens 6. A photo-cell 10 is mounted close to the edge of image 9 and when the image increases in size the cell is illuminated and motor 14 switched on by relay 11 to rotate threaded rod 13. This moves cell 10 by means of runner 12 until the cell is again beyond the image and at the same time rotates disc 15 to vary a resistor or rotary transformer in the heater current circuit. If required, to achieve greater accuracy, a second photo-cell system may be used monitoring the position of the other extremity of image 9.

Abstract: 607,970. Starting prime movers. TRIGGS, W. W. (Akt.-Ges. Brown, Boveri, & Cie.). Nov. 16, 1945, No. 30770. Addition to 592,639, [Group XXXIII]. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 26, 1946.] [Class 38 (iv)] A gas turbine ship propulsion plant is started by a dynamo-electric machine 10, Fig. 1, which receives power from one or more dieselelectric sets 11, 12, and drives the turbine up to about one-third normal speed, the machine subsequently being driven as a generator by the turbine and assisting or replacing the sets 11, 12 in the supply of power to the auxiliary mains 17. The ratio of the gearing between the machine 10 and the turbine remains constant. For starting purposes, machine 10 may operate with a series field winding, this being replaced, when the machine is to generate, by a shunt winding providing the weaker excitation required on account of the higher speed of the machine. An automatic voltage regulator 20 may also be provided. The machine 10 may be in Ward-Leonard connection with one of the sets 11, 12 during starting. When the auxiliary services are operated by three-phase alternating current, the propulsion plant is started by a pole-changing synchronous asynchronous machine 22, Fig. 2, which is run up as an induction motor from the auxiliary supply mains 21 on a low pole number by starter 25. Alternatively, one of the auxiliary diesel sets 23, 24 operating with gradually increasing voltage may start the machine 22. When the turbine is self-running, the pole number of machine 22 is increased and D.C. excitation applied by machine 27 so that machine 22 may supply the auxiliary mains 21.
