Title: Improvements in sliding sash windows
IPC: E06B3/44
Filed: 1923-01-27
Abstract: 213,718. Cruze, W. A. Jan. 27, 1923. Fastenings for sliding doors and windows.- Each sash 1, 2, is provided at diagonally opposite corners with rollers 4 carried in brackets 5 and at the other diagonally opposite corners with springs 6 doubled over on themselves and having a flat end secured to the sash and a coiled end pressing against the groove 7 in the frame 3. With heavy sashes, when springs of a powerful nature are employed, a roller 10, Fig. 6, may be attached to the spring 6 by bending the end of a spring around the reduced central portion 11 of the roller. The sashes may be secured in the closed position by a pin 12 inserted at either side of the window frame in one of a number of holes 13 in a plate 14, the pin 12 passing through the coinciding loops of the spring 6, if inserted at the lefthand side, or through one of a number of slots in the bracket 5 on the lower sash and just below the lower end of the bracket 5 on the upper sash, if inserted at the right-hand side. Either the upper or the lower sash can be secured in an open position by passing the pin 12 through a hole 13 which coincides with one of the slots in a bracket 5 or with the loop of a spring 6. When not in use the pin 12 may be inserted in a hole 16, Fig. 10. The sashes may be removed from the frame 3 by sliding them so as to bring the springs and rollers opposite slots 17 in the frame, the slots being normally filled by blocks of wood 18 secured to the parting and inside beads 19, 19 of the frame as shown in Figs. 14 and 3 respectively. Coil springs may be arranged in the frame 3 to assist in lifting the sashes. According to the Provisional Specification, the device may be applied to sliding doors or shutters.

Abstract: 727,836. Spray-producers. FOUNDRY SERVICES, Ltd. Jan. 29, 1954 [Jan. 29, 1953], No. 2616/53. Class 69 (3). A spray gun is supplied with compressed air and sprays liquid located in a container, and it is so constructed that it is held and operated by one hand so that it can alternatively be used for spraying, blowing, or agitating the liquid in the container. The gun body 10 is supplied with compressed air by a pipe 13, and a pipe 14 connects with the liquid container. When a normally closed valve 16 is depressed and opened by the base of the operator's thumb, and a vent 21 closed by the ball of the thumb, Fig. 3, compressed air passes through passages 17, 18 and nozzles 19 and 22 to cause spraying. With the vent opened a blowing action is effected, and by closing the nozzle 22 with the first finger and closing the vent 21 compressed air passes back to the container to agitate the liquid therein. The liquid passage 30 contains a throttle piece 26 with a bore 28 of a size depending on the liquid viscosity.

Filed: 1957-01-28
Abstract: 862,322. Servo systems. NATIONAL RE. SEARCH DEVELOPMENT CORPORATION. April 16, 1958 [Jan. 28, 1957], No. 2932/57. Class 40 (1). [Also in Group XXXV] In a closed loop control system correction of an output quantity is proportional to error in correspondence between input and output quantities and the gain is greater when the error is increasing than when it is decreasing. In Fig. 1, selsyn units 3 and 7 respectively associated with input and output shafts 1 and 5, are interconnected so that any output signal produced by lack of positional correspondence between the shafts is applied through an amplifier 12 to run a two-phase servomotor 14 in the appropriate direction to restore correspondence by adjustment of shaft 5. A phase-sensitive rectifier 19 responsive to the output of amplifier 12 controls a polarized relay A so that a twoway contact 26 controlling the connection of a relay B to positive or negative supply terminal 27A or 28A is set to a position corresponding to the sense of the error. Contacts operated by a beam 22 slipping on the shaft of servomotor 14 connect relay B to a further positive or negative supply terminal 25A or 24A according to the sense of servomotor operation. The arrangement is such that relay B is de-energized to open contacts B1 and reduce the gain of amplifier 12 when the error and rate of correction of error are of opposite sense, i.e. when error is being reduced.

Abstract: 480,826. Controlling variable-speed gears. SCHOENING, H., (trading as RABOMA MASCHINENFABRIK H. SCHOENING). Feb. 2, 1937, No. 3098. Convention date, Sept. 30, 1936. [Class 80 (ii)] [Also in Group XXIX] A servomotor - control device for adjusting the change wheels of machine tools wherein the plunger can be set in more than two positions has the plunger which is provided with a series of peripheral recesses, arranged to work in a cylinder having a series of ports which can be used selectively for the admission and exhaust of liquid under pressure. The plunger is constructed so that after moving under the influence of liquid admitted through a selected port it cuts off the inflow through that port and the outflow through another port so that the plunger is stopped in the desired position. In the form shown in Fig. 1 the plunger has two peripheral grooves 3, 31 connected by passages 41, 4 to end chambers remote from the grooves. If pressure is admitted at 7 and exhausted from 8 the plunger moves to the extreme right-hand position. If pressure is admitted at 5 and exhausted at 6 the plunger moves to the mid-position from either the right- or left-hand position. In the form shown in Fig. 4, in which the plunger can be moved to either of four positions the cylinder has supply and exhaust ports 13, 14 at each end and supply ports 16, 18 and exhaust ports 15, 17 midway between the ends. The plunger is provided with a series of longitudinal peripheral grooves. Grooves 26, 27, co-operating with exhaust port 15 and grooves 22, 23 co-operating with exhaust port 17 lead to opposite faces of the plunger. Grooves 24, 25 co-operating with inlet port 16 and grooves 20, 21 co-operating with inlet port 18 terminate short of the end faces of the plunger and are connected by internal passages with the end faces remote from the grooves. To move the plunger to one of the intermediate positions pressure is admitted to either port 16 or port 18 and exhausted from the corresponding exhaust ports 15 or 17. Additional grooves may be formed in the plunger for moving the plunger to its end positions in place of using the ports 13, 14 or for moving the plunger to other intermediate positions.

Abstract: 1286793 Preparing semi-conductor wafers ELEKTROMAT VEB 24 Jan 1970 3529/70 Heading G2A In contact printing through a mask on to the surface of a semi-conductor wafer during the manufacture of integrated circuits, the wafer is located against an orientation plate and locked in position, after which the plate is replaced by the mask. Thus the wafer is aligned parallel to the mask without actually touching it, so avoiding damage thereto. The mask 2 is mounted on a carriage 11, and the orientation plate 3 on a carriage 12, the two carriages being linked by a leaf-spring 4 and movable together on a table 7. The table has grooves 8, and each carriage runs on bearings 6, so that either carriage can be accurately located by the bearings resting in the grooves. Initially, carriage 12 is so located, as shown in Fig.3, and held there by vacuum suction through carriage 9. A support 5 carrying the semi-conductor wafer 1 extends through an opening 15 in table 7. The support is raised and adjusted until the wafer 1 lies flat against the under surface of plate 3. This has a central land 10 extending downwards a distance a beyond the remainder of the surface. Support 5 is now locked in position, and the suction in carrier 9 released, so that the unitary carriage structure 11, 12 can be moved to the right, from the position of Fig.3 to that of Fig.4. The mask 2 is now located exactly parallel to wafer 1, but spaced from it by the distance a. Adjustment of the mask in mutually perpendicular directions in this plane can now be effected by adjustment screws (13, 14) Fig.2 (not shown). When the correct positioning has been obtained, support 5 and wafer 1 are then moved upwards by the distance a, so that wafer and mask are now brought into contact, and the exposure is made.
