Title: Accordion-pleated type screen for heat-insulating purposes
IPC: E04B1/78
Filed: 1954-07-27
Abstract: 756,270. Folding screens. JANSON, E. U. July 27, 1954, No. 21969/54. Class 20(3). An accordion-pleated screen, particularly for heat insulating purposes, is built up from a number of identical elements 5 which are each formed by folding a sheet of flexible material, e.g. cardboard, canvas, or plastic, in the form of an H to form air pockets 3 and gluing their stems together at 2, so that air pockets 4 are also formed between the middle webs of neighbouring H elements. The screen folds down as shown in Fig. 2. A screen can be formed of double-H elements each having four stems interconnected by cross webs so that seven air pockets are provided in the direction of insulation. The insulation properties may be further improved by coating the wall surfaces of the air pockets with heat reflecting colour, or by attaching heat reflecting linings, e.g. metal foils, to them. If it is desired to have a light transmissive screen, slits 9 can be included without causing any essential reduction in the heat insulation. In modifications, the walls of the air pockets may be formed by continuous vertical sheets joined by cross webs and folded in parallel folds, or the walls of the air pockets are formed from shorter lengths of material each having one fold and being articulated to neighbouring strips and cross webs. The screen can be operated by cords like a venetian blind.
Patent GB-615113-A (GB)
Title: Improvements in or relating to cathode beam tubes
IPC: G01S1/02
Filed: 1946-07-24
Abstract: 615,113. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 24, 1946, No. 22109. Convention date, July 24, 1945. [Class 39 (i)] [Also in Group XL (c)] In a cathode-ray tube the electron beam scans a dielectric target through a screen at the surface of the target facing the electron gun, and electrical signal potentials are applied to a plate electrode on the side of the target remote from the gun; secondary electrons returning to an electrode on the gun side of the target provide the output. The scanned areas of the target are brought to the potential of the screen by the scanning of the beam across the target. After a signal is impressed upon the target, the target reverts to the potential of the screen, but an individual area of the target retains a potential as much below that of the screen as that which the signal had above. In a pulse radar system, successive echoes from a stationary object are identical, and for each echo the potential of the isolated target area rises to that of the screen, and the secondary electron output beam will be unmodulated. Echoes from moving objects, however, will vary in phase and amplitude and the output will be modulated. The dielectric target 3 which may be circular or rectangular, may be of mica with a metallic coating forming the signal plate 22, or of aluminium oxide, when it may be formed by anodizing one side of an aluminium signal plate. An earthed screen 23 is in intimate contact with the target 3. The output electrode is the final electrode 19 of an electron multiplier surrounding the electron gun 2. The front surface 7 of the anode 6 forms the first dynode and the other dynodes 15, 16, 17 each consists of slanting radial blades 20 held in an annular frame. A screen 21 is secured to the frame in front of the blades. The secondary electrode 18 is the final multiplier stage and consists of a flat annulus. A tubular electrode 9 directs secondary electrons from the first dynode 7 into the succeeding multiplier stages. In addition to deflecting coils 11 and focusing coils 14, an adjustable coil forming a transverse magnetic field is provided to compensate for misalignment of the cathode beam due to mechanical imperfections, as described in Specification 628,745.

Title: Process for the production of a benzine-soluble oil-resin size
IPC: D06M15/17
Filed: 1938-07-26
Abstract: 509,538. Resin sizes. MASCKE, C. July 26, 1938, No. 22259. Convention date, July 27, 1937. [Class 91] A benzine-soluble oil-resin size for dressing artificial silks is made by partly saponifying a solution or dispersion of resins in non- drying or semi-drying oils and fats, by alkali, till benzine-solubility of the product is reached. Thus, two parts of semi-drying oil (e.g., rape seed oil) or two parts of non-drying oil (e.g., olive oil), eight parts of resin (e.g., fine resin) and one part of wax (bees, carnauba or palm) are melted and treated with from 2 to 10 per cent. by weight of alkali or salts having an alkaline reaction such as borax. When melting is complete the partial saponification produces a benzine-soluble size suitable for use with cuprammonium silk. Synthetic resins may be used.

Abstract: 396,228. Bedsteads. EVANS, R. Y. K. N., EVANS, D. K. L. N., and EVANS, J. K. N., King Street, Wednesbury, Staffordshire. Aug. 9, 1932, No. 22274. [Class 52 (ii).) A bedstead for hospital use comprises a bed surface frame tiltable in relation to the bedstead frame about either of two axes at right-angles, the tilting being effected in each case through the same lifting and lowering gear which is adjustable according as tilting about one or the other axis is required. The bed surface frame c is provided near the foot end with lateral trunnions c<2>, c<3>, the former being carried by a sleeve c<4> rotatably mounted on one side bar a<3> of the bedstead frame and the latter normally resting on a lug a<4> on the other side bar a<3>. The frame c near its front end is provided at one side with a bearing pin c<5> resting on a lug c<6> on one side bar a<3> of the bedstead frame and at the other side with a U-shaped bearer bracket c<7> normally resting on the other side bar a<3>. Lifting and lowering are effected through a manually rotatable shaft d<2> mounted in brackets d depending from the side bars a<3> and provided with right and left hand threads fitted with screw boxes d3, d<4>. To the box d <4> is pivoted at e<3> a stirrup f rigid with a link e pivoted to one side of the frame c, and to the box d<3> is pivoted at e<4> a similar stirrup f formed with a U-shaped upper end pivoted at f<3> to a link e<2> pivoted to the other side of the frame c. When the frame c is to be tilted about the trunnions c<2>, c<3> the joint at the pivot f<3> is made rigid by inserting a pin g through holes in the walls of the U-shaped end of the stirrup, whereas, when the frame c is to be tilted about the side bar a<3> with the sleeve c<4> and the bracket c<7> as bearings, the pin g is removed and is preferably inserted in holes h in the bracket c<7>. In a modification the operating screws are on parallel shafts geared together through spur wheels adapted to be disengaged by sliding one wheel on its shaft and the link e<2>, like the link e, is rigid with its stirrup f. In this case tilting about the trunnions c<2>, c<3> is effected with the wheels in mesh and tilting about the side bar a<3> is effected with the wheels disengaged, the necessary movement of the link e<2> being permitted by providing slots l, Fig. 8, in the stirrup f for the pivot at e<4>. According to the Provisional Specification the links may be arranged to telescope.

Abstract: 1520975 Measuring moisture electrically SAINT-GOBAIN INDUSTRIES 28 May 1976 [2 June 1975] 222291/76 Heading G1N (A) [Also in Division H5] A window pane with heating elements deposited thereon includes a moisture detector Fig. 3 comprising a pair of adjacent electrodes 11, 12, and a terminal 10 mounted on a conductive layer 14 on the pane surface, the whole of the detector including the terminal being within the area of the pane which is freed of moisture by the heating elements. The electrodes are interdigitated and the collector for electrode 12 is formed by the upper heating element 4. A conductor 17 screens the detector from leakage currents and an upstanding portion 18 channels away any water droplets running down the pane. When the size of the area demisted is limited by the available power supply the detector may be situated in an auxiliary area 27 formed by a localised diversion of an element 22. This avoids long connections to the detector passing across the window. In a further embodiment Fig. 5 (not shown) the detector is formed between two elements (19, 20) at the side of the pane, the said elements forming collectors for one of the electrodes (12). Reference has been directed by the Comptroller to Specification 1458092.

Title: Improvements relating to fuel injection pumps for internal combustion piston engines
Inventor: PATERSON THOMAS
IPC: F02M59/44
Filed: 1953-09-02
Abstract: 723,170. Fuel injection systems. SIMMS MOTOR UNITS, Ltd. Sept. 2, 1953 [Sept. 4, 1952], No. 22300/52. Class 7 (3). A stop 6, limiting the normal maximum fuel delivery of a fuel injection pump controlled by a control rod 1 which is actuated for example by a governor, is held in its operative position by means 4 actuated by the outlet pressure of a feed pump 2 supplying fuel to the injection pump and moves to a position permitting the control rod 1 to be set to an excess fuel supply position for starting in consequence of stoppage of the feed pump 2. The stop 6 is carried by a spring-loaded rod 5 attached to a diaphragm 4 and is normally held by the feed pump delivery pressure in a position to contact the end of the rod 1 to limit the normal maximum fuel supply. When the feed pump pressure drops on stoppage of the engine, the rod 5 is raised by a spring 8 to move the stop 6 opposite a stepped portion 7 of the rod 1, whereby the latter is moved by the governor beyond the normal maximum position to supply excess fuel on restarting of the engine. As soon as the engine has started the rod 1 is moved back to a normal regulating position by the governor and the delivery pressure of the pump 2 moves the stop back to its normal position.

The drive arm 51 may be selectively operated by a solenoid pivoting the ramp 80 between in-use and out-of-use positions. Where the carrier runs along an incline a ramp 81 may be provided to engage peg 46 of dog 41 and prevent the dog from moving out of contact with post 30. To accumulate carriers a stop 90 may be moved into the path of a carrier to contact the forward ramp 44 of dog 41 thereby lifting the dog and disconnecting the drive. A succeeding carrier will have its drive dog lifted by the rear drive member of the first carrier and thus the carriers will accumulate until the stop is removed and a drive dog can engage the post of the first carrier in the line.

Abstract: 587,296. Loading and unloading vehicles; winches. BROOKS (MISTLEY), Ltd., CRISP, F. V., and POWELL, L. Nov. 14, 1944, No. 22489. [Classes 78 (iii), 78 (iv) and 78 (v)] Apparatus for unloading and loading goods such as sacks from or on to vehicles comprises a framework A resting on the ground and against a side of the vehicle and having a platform P which is raised in guides B by a wire E passing over rollers D, D<1> on the framework and connected to a cable of a winch H on the vehicle chassis. The winch is driven from a power take-off shaft O through a clutch P and bevel gearing L, M. The clutch is operated by a cone N' which is moved longitudinally on a shaft N by a rock shaft T which engages a yoke on the cone and is rocked by an arm W operable from the rear of the vehicle through a wire X connected to a handle Z. An arm V on the shaft T operates a bell crank lever V to apply or release a brake on the drum K. For loading sacks on to the vehicle the arm W is moved by the operator to position 3, Fig. 1, whereby the clutch is engaged and the winch driven so as to raise the platform P to the level of the vehicle floor. The wire X is then released to allow the arm W to drop back to position 1 in which the clutch is disengaged and the brake applied. After transferring the sacks to the vehicle, the arm is moved to position 2 to effect release of the brake and disengage the clutch so that the platform may now fall by its own weight to the ground.

Title: Improvements in or relating to pilot operated fluid flow control valves
IPC: F16K31/40
Filed: 1957-07-16
Abstract: 821,903. Valves. HAYS MANUFACTURING CO. July 16, 1957 [Aug. 6, 1956], No. 22540/57. Class 135. [Also in Group XXXV] A main valve closure 16, which embodies a resilient washer 23, is maintained on a seat 24 by fluid pressure in the inlet 14 leaking past the surface 65 of a piston 17 and into a chamber 66 thereabove, the piston 17 being integral with the closure 16 and, since the area above the piston is greater than that below, the closure is forced on to its seat. Upon energizing a solenoid 39 an iron plunger 52 is lifted to open an orifice 61 through the piston 17 and relieves the pressure in chamber 66 whereby the piston 17 rises and the main closure is unseated. The closure 16 has a V-shaped slot 20 to gradually cut-off the fluid flow as the valve closes and thus eliminate water hammer. An aperture 25 in the seat partition 11 enables a small flow of liquid to take place at all times to ensure that the thermostat in an air conditioning installation is maintained at a representative temperature. The plunger 52 slides in a non-magnetic tube 34 soldered to the valve bonnet 31 and having a counterbore 38 at the lower end whilst at the upper end of the tube is a stop member which comprises a tubular copper shading coil 47 and a solid metallic shading pole 49. In the bottom of the bore 53 is a rubber or plastic member 54 impregnated with magnetic particles, which member in the elevated position of the plunger 52 receives the coil 47 and pole 49, the latter attracting the member 54 between alternating current cycles in the solenoid 39 to hold the plunger 52 against vibration, the rubber or plastic serving as a buffer and a magnetic path. On the lower end of the plunger 52 is a rubber tip 59 of larger diameter than the plunger having a pilot valve closure 60 cooperating with the orifice 61 in the piston 17, the tip 59 abutting the bonnet 31 and tube 34 when the solenoid 39 is energized, thereby reducing noise.
