Title: Improvements in or relating to recording and reproducing devices
IPC: G08C19/02
Filed: 1947-06-19
Abstract: 614,705. Electric control systems. HUMAN, A. H. June 19, 1947, No. 15211/46. [Class 40 (i)] A recording and reproducing device cornprises a movable recording surface H of electrically insulating material, a recording element A<SP>4</SP> acting to mark on the surface an electrically conducting trace H<SP>1</SP> representative of a variable quantity to be recorded or reproduced, and a control element J, J<SP>1</SP> with which the record can subsequently be brought into engagement for varying the amount of resistance in an electric control circuit in accordance with the height of the conducting trace above a datum line. As applied to an average measuring device giving, at any instant, an average value (e.g. of displacement or electricity consumption) over the unit of time preceding such instant, the rotation of a wheel A<SP>6</SP> represents the value concerned, and the movement of the recording element A<SP>4</SP> represents the rate of change of this value. Current for a motor J2 passes through resistance rollers J, J<SP>1</SP> connected by the ink trace and thus the speed of motor J<SP>2</SP> varies according to the height of the trace. The angular displacement of the shaft of the motor is continuously subtracted from that of shaft A (driven from the gear A<SP>6</SP>) by means of a differential gear C and the resulting movements of an indicating or recording arm D are proportional to the required average. The ink trace H<SP>1</SP> may be removed from the drum by a scraper H<SP>2</SP>, or a continuous web may be employed so that the trace can be retained. The drum H and record surface D<SP>1</SP> may be driven by a common clockwork mechanism F. In a modification, one of the resistance rollers J is replaced by a conducting roller which need not be so close to the other roller. In another embodiment, the mechanical drive to the shaft A is replaced by another electric motor controlled by a further pair of resistance rollers immediately following the pen A<SP>4</SP>. The subtraction performed by the differential C may be done electrically or by other means.

Title: A method of covering a pipe bend or similar curved pipe section, already bearing a heat-, cold- or sound insulating layer
IPC: F16L59/11
Filed: 1965-04-09
Abstract: 1,107,351. Insulating pipe coverings; pipe bends. FARBWERKE HOECHST A.G. 9 April, 1965, [9 April, 1964], No. 15229/65. Headings F2G and F2P. A method of covering a pipe bend or similar curved pipe section 3, which already bears a heat, cold-, or sound-insulating layer comprises encasing the bend or section from opposite sides in two rigid prefabricated shells 2 of plastics material and securing the shells in place. The edges of the shells may be arranged to abut, in which case, they may be secured in position by strips or bands of adhesive tape along at least part of the line of abutment. Alternatively, pipe clamps or light metal bands, which extend around the pipe, may be used. If the edges overlap, as shown, the securement may be achieved by welding 4. The shells may, as a further alternative, be formed with projecting edge flanges extending partially or fully their length and the flanges secured by welding, bolts or locking pins. The shells may be formed from deep-drawn rigid sheets of polyvinyl chloride, copolymers thereof, or similar plastics material. If the pipe bend or curved section subtends an angle which is a sub-multiple of 360 degrees, the shells may be obtained by cutting sections from a deepdrawn ring of semi-circular cross-section.

Sept. 21, 1918 Parachutes; propelling; steering and balancing. - A parachute device for use with aeroplanes &c. comprises a pilot parachute and a main parachute separately housed in compartments in the fuselage and arranged so that the compartment containing the pilot parachute may be opened to the air-stream, whereupon the pilot parachute is projected upwards and pulls out the main parachute. Means are provided also for depressing the tail of the machine to counteract a nose-dive and to ensure that the aviator shall be drawn clear of the tail by the parachute. Fig. 1 shows a pilot parachute 10 housed in a compartment 9 and connected to the apex of the main parachute 1 in another compartment 2, both compartments being closed by a lid 6. Side doors 19, 21 and bottom doors 20, 22 may also be provided in the compartments. The tail is depressed by operation of the elevator, and also by an air ejector device 23 such as that described in Specification 1077/15, and to which high-pressure air may be admitted from a reservoir 24 so as to produce an upward blast of air through an opening normally closed by a lid 31; when in the open position, the lid 31 slopes backwards and acts as an additional elevator to depress the tail. The whole apparatus is controlled from a handle 26, the initial movement of which admits air to the ejector 23 and releases the lid 31, which is then thrown open. If this is sufficient to right the machine in the event of a nose-dive, the handle 26 can be replaced and the parachutes not released. To release, the parachutes, however, the handle 26 is operated to its full extent, whereby the lid 16 is released and springs open, and the doors 19 - - 22 are also opened. The pilot parachute is then ejected by the current of air and draws out the main parachute, which is connected with the aviator. The elevator and, if desired, the ailerons may also be actuated by the handle 26 for depressing the tail. Means may be provided whereby, when the pull of the main parachute is about to be transferred to the aviator. the holding-down straps of his harness are released, and the seat-back is allowed to fall back to facilitate his withdrawal.

Abstract: 1381654 Linkwork; valves E J WEBER 5 April 1972 [31 May 1971 21 March 1972] 15579/72 Headings F2K and F2V [Also in Division H1] A control device for a microswitch 78, Fig. 1, or fluid pressure valve is operated by a sensing means such as a fluid pressure diaphragm 6, 18 via a rocking plate 42 having first and second axes (A) (B), Fig. 2 (not shown), about which it pivots sequentially against a pair of light and heavy biasing springs 52, 53, at least one of which is adjustable and having their lines of force intersecting a respective one of the axes. The arrangement is such that on operation a microswitch 78 or the like having a very small differential movements between the "on" and "off" positions may be given a large adjustable differential where the springs 52, 53 are respectively "light" and "heavy". The rocking plate 42 engages a fixed stop 50 at its intermediate position corresponding that between the "on" and "off" positions of the switch and at which the rocking plate 42 changes its pivot axis from one (A) on a pair of balls 46 (48), Fig. 2 (not shown), to act against a light spring 52 to another (B) on a pair of balls 47 (48) to act against the heavy spring 53. The balls 46, 47, (48) are in a triangular formation, Fig. 2 (not shown), and have their movements limited between top and bottom plates 20, 50. A resilient connection between the plate 42 and a push rod 84 for the switch 78 is provided by a "U"-shaped leaf spring 86. In a modification Fig. 9, the fluid pressure diaphragm 6 acts at the centre of a double armed lever 150 which initially pivots about one end 160 against the action of an adjustable light tension spring 153 coupled at the other end 173. Movement continues until the end 173 engages a fixed abutment pivot 171 so that further movement of the lever continues by pivoting about the pivot 171 against the action of an adjustable heavy tension spring 152 at the opposite end 160. A large adjustable differential for the force applied to the lever 150 is thereby obtained for the actuation of the switch or valve 78.
