Title: Improvements in variable electric condensers
IPC: H01G5/12
Filed: 1924-01-25
Abstract: 228,006. Spink, J. R., and Langley, J. B. Jan. 25, 1924. Condensers.-In a variable condenser of the kind having overlapping cylinder segments, the adjustable segment or segments are capable of axial as well as rotary movement. In one construction, Fig. 1, a fixed segment 1 is mounted on a cylindrical insulating member 3 having a screw-threaded end 4 engaging the panel 5 and a movable, segment 2 is carried by a spindle 6 slidably and rotatably mounted in the member 3. The terminals 7, 8 are mounted on the member 3, the terminal 7 being connected to a lug on the segment 1, while the terminal 8 is connected to the spindle 6 through a spring and shoe bearing on the spindle. In another construction, groups of intermeshing segments are connected to discs mounted on the member 3 and the spindle 6, the segments of one of the groups being preferably extended through different arcs. In another construction, Fig. 4, the movable segments are arranged in two groups, which can be adjusted relatively to each other as well as to the fixed segments. One group of movable segments 2<b> is carried by a disc 15 on the end of the spindle 6, while the other group 2<a> is carried by a disc 14 on the end of a sleeve 13 which surrounds the spindle 6 and is provided with a separate operating member 17. The sleeve is slidably and rotatably mounted inside the insulating cylinder 3 carrying a disc 16 which carries the fixed segments 1<a>. In another construction, Fig. 5, a fine adjustment is obtained by axial adjustment of the cylinder 3, which for this purpose is mounted on a fixed metal sleeve 20 carrying the spindle 6. A plate 22 on the end of the cylinder 3 carries a nut 23 engaging a screwed spindle 24 provided with an operating knob 25. A shoulder on the spindle 24 engages a fixed plate 26, so that rotation of the spindle effects a slight axial adjustment of the cylinder 3. Sheets of mica may be introduced between the cylinder segments to increase the maximum capacity.

Patent GB-835283-A (GB)
Title: Improvements in servo-motor actuated artificial limbs
IPC: A61F2/58
Filed: 1957-01-21
Abstract: 835,283. Artificial limbs. HAFNER, O. Jan. 21, 1957, No. 2183/57. Class 81 (2). The joints of an artificial limb are moved by pressure actuated servo-motors and the controlling valves for these are operated by means of the user's remaining muscles. In the arm shown pneumatic motors 7, 7a, 7b, Fig. 1, in the form of tubular bellows, actuate the elbow, wrist and thumb respectively and the elbow and wrist may be locked in set positions by detents 9, 9a, actuated by further pneumatic motors 10, 10a. In each case the return movement is effected by springs. In the form of control valve assembly shown in Fig. 3, the valves are actuated by rotational movement of the stump within the socket, whereby the pressure member 30 is turned in one direction or the other. Rotation in a counter-clockwise direction lifts a valve 17 and admits compressed-air from a union 21 to a channel 25 and so to an outlet 27 connected to the servomotor. Rotation in the opposite direction allows valve 17 to close and opens exhaust valve 18 whereby the air passes out through a porous rubber plug 38 in a duct 37. The operating members 23 bear against sealing diaphragm 22 which receive the pressure of the enclosed gas and thereby give an indication to the user of the pressure being exerted by the appropriate servomotor. In other arrangements the valves are held against muscles so as to be actuated when the muscles are tensed and the inlet and exhaust valves may be combined to be actuated in sequence by increasing the muscle tension. It is further proposed to actuate several valves in sequence by rotatable cam arrangements and to have a distributer mechanism whereby either of two limbs may be selectively actuated by the same control valves.

Title: Improvements in or relating to windscreen cleaners
IPC: B60S1/08
Filed: 1924-01-28
Abstract: 231,970. Aufiero, E. Jan. 28, 1924. Windows and the like, cleaning.-In a cleaner operated by electric motor, the motor and reduction gearing are so arranged in a rectangular casing adapted to be fixed to the frame of the wind-screen that each occupies substantially the full cross-sectional area of the casing. The fieldframes of the motor comprise substantially L- shaped members 4 fixed to the casing 1 by a bolt 9, each having a part 5 partially surrounding the armature 3, and the field coil 7 is offset longitudinallv of the armature so that the motor shaft 6 lies diagonally in the casing. Bearings in a partition 2, which divides the casing into two parts, and in a removable end wall 10 support the shaft 6, the wall 10 also carrying the brush mechanism 15. One of the brushes may be lifted from the commutator to stop the motor by turning an external handle 26. The motor shaft extends through the partition 2 and carries a worm 11 driving a worm-wheel 12 having formed on its hub a level pinion 13 with which engages an internal elliptical gear 29, Fig. 11, extending partially around the circumference of a sleeve 30. A pin 34 projecting from the end of the wormwheel spindle takes in a cam-groove 33 on the sleeve 30 so that the gears are kept in mesh, the sleeve sliding on its hexagonal shaft 31 while oscillating the shaft. The arm 32 of the wiper 43 is fixed to the shaft 31 by a clamp 46 and key 37, the shaft projecting through a bearing 35 in the casing 1. To lessen friction between the sleeve 30 and its hexagonal shaft the corners of the hexagonal hole in the sleeve are cut away. The casing is closed by a cover plate 40 and the gear compartment is filled with grease or oil.

IPC: B32B7/023
Filed: 1931-01-23
Abstract: In articles comprising several pieces of sponge rubber of different nature, integrally united, the different portions of rubber are produced by moulding, spreading, dipping, &c. frothed aqueous dispersions of rubber or the like, still in a reversible condition, e.g. as described in Specifications 332,525 and 332,526, [both in Class 70, Indiarubber &c.].  The different portions may vary in colour, porosity, hardness, &c.  The froth may be made from concentrated latex such as is described in Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], and may contain compounding, vulcanizing, colouring, &c. ingredients.  According to an example, a mould is partly filled with a frothed latex, sodium silicofluoride is added to cause it to set, the mould is filled with another froth of different density, this froth is set, and the composite article is vulcanized in steam before drying.  Patterned articles may be made by filling coloured froth into compartments in a mould formed by movable partitions, setting the froth, removing the partitions, and filling up with froth of other colour.  Each section of set froth may be vulcanized before applying the next section, but this is not so satisfactory.  Specification 358,561 also is referred to.

Title: Improvements in or relating to refrigeration systems
Inventor: ANDERSON NORMAN
IPC: F24F5/00
Filed: 1958-01-25
Abstract: 915,124. Ventilating aircraft. GODFREY & PARTNERS (HOLDINGS) Ltd., Sir GEORGE. Jan. 23, 1959 [Jan. 25, 1958], No. 2573/58. Class 137. [Also in Groups XIII and XXVIII] In apparatus in which cold air from an expansion turbine 7 flows through a pipe 12 and water extractor 14 to an aircraft cabin 15, icing-up of extractor 14 is prevented by providing in pipe 12 a foraminous element 13 of such hole size that any ice formation blocks it, thus causing a rise in the air pressure and temperature at the turbine exhaust, the rise in temperature melting the ice. Air from the tapping 1 of a gas turbine compressor passes through cooler 3, control valve 5 and compressor 8 driven by turbine 7 to a cooler 10 whence it flows to the turbine. Also air for warming the cabin can be fed from tapping 1 direct to pipe 12 through pipe 26 and another passage of valve 5 which can thus supply hot, cold, or mixed air. In flight, the air stream cools exchangers 3, 10, but, on the ground, high-pressure air from tapping 1 flows to ejectors 30 in the exchangers to induce a cooling air stream. Element 13 consists of a fine metallic gauze or a plurality of such gauzes across the air flow passages.

Title: Improvements in combination single-phase line frequency welder and impulse welder
IPC: B23K11/24
Filed: 1954-01-28
Abstract: 755,747. Rectifying. SCIAKY, D. Jan. 28, 1954, No. 2586/54. Class 38 (2). In a welding system fed from a singlephase alternating current supply L<SP>1</SP>, L<SP>2</SP>, wherein the centre tap of the primary winding 13, 14 of a welding transformer 10 is connected to the line L<SP>1</SP> and the ends of the primary winding are connected to the line L<SP>2</SP> by way of reversely connected ignitrons 27, 32, the firing of which is controlled by thyratrons 30, 34, switching means 23, 24 are provided the various positions of which cause the current at the weld 16 to be either in the form of positive or negative unidirectional pulses, or to be of alternating form at the same frequency as the supply frequency. When the switches 23, 24 are in positions AC, DB, as shown in Fig. 1, the current associated with the primary winding of the transformer 10 will be in the form of a series of additive pulses flowing alternately in the halves 13, 14, thereby causing a steady rise of flux so that a positive pulse of unidirectional current is induced in the secondary winding 12 and thus the system operates as an impulse type of welding apparatus. Movement of the switches 23, 24 to positions A, B<SP>1</SP>; D, C<SP>1</SP> causes a similar type of operation with the exception that the pulses are in a negative direction. Movement of the switches to positions A, C; D, C<SP>1</SP> or alternatively to positions A, B<SP>1</SP>; D, B causes a single phase current to flow in the transformer windings only one half, 13 or 14, of the primary winding being used however, according to the position of the switches 23, 24. Thus during operation of the system as an impulse welding apparatus the ignitrons 27, 32 act as rectifiers whilst during operation as a single-phase line frequency welding apparatus the ignitrons act as electronic contactors. During operation of the system as an impulse welder a polarized relay is connected across the transformer primary winding, the relay being operative to cause the direction of unidirectional pulse to be alternately positive or negative each time the operator actuates the main switch of the system. In another embodiment of the invention the switches 23, 24 are replaced by ignitrons suitably connected. The Specification outlines the operation of a welding system which includes squeeze, weld and hold timing means. The winding arrangements of the primary winding are also described.
