Filed: 1923-08-29
Abstract: 203,331. Booth, G. H., (Assignee of Woolley, R. B.). Aug. 30, 1922, [Convention date]. Manuscript blocks; refill attachments; indexing.-A diary comprises two annual sections 1, 2, removably held one on each of two stiff sides 5, 6 of a cover by the engagement of a tongue or cover 10 on the section with a pocket 7 on the cover side opening towards the hinge 9 of the cover, the monthly, and preferably also the daily or weekly divisions of each section being marginally indexed. The sections 1, 2 have a tongue or cover on each side so that at the end of the year, the section 1 for the earlier year can be removed, the section 2 for the succeeding year moved from the side 6 to the side 5, and a rear section added to the side 6. Between the sections 1, 2 a removable, marginally-indexed, central section 12 may be held by tongues or covers 13 in the pockets 7 beneath the tongues 10. The sections 1, 2, 12 may be arranged so that, when they are superposed as in Fig. 1, the monthly indexes on the sections 1, 2 and an alphabetical or numerical index on the section 12 are all visible. Daily indexes 15 may be placed on the bottom or other edges of the monthly divisions. The indexes may be visible from both sides, the tabs being printed on both sides.

Title: Protective arrangements for pulse generator circuits
Inventor: SCOLES GRAHAM JOHN
IPC: H03F1/54
Filed: 1952-08-29
Abstract: 715,871. Pulse generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 23, 1953 [Aug. 29, 1952], No. 21824/52. Class 40 (6). [Also in Group XXXV] In a pulse generator of the type in which a reservoir circuit is charged through an inductance and periodically discharged through a load on triggering a discharge device, in the event of an excessive voltage being built up in the circuit so that a reverse voltage is produced, a capacitor is charged in the grid circuit of a discharge tube so that the tube conducts and a protective discharge circuit is completed. The Figure shows the circuit of a high voltage pulse modu'ator in which the pulse forming network L is charged from a D.C. supply via inductor H and diode D1 and on triggering of ignitron I is discharged through a transformer T with which a magnetron load M is associated. In the event of an excessive voltage being produced at point A, due to a fault in magnetron M acting as a short-circuit so that point A swings negative, capacitor C1 is charged through diode D3 and the grid of valve V1 is driven positive. When point A swings positive valve V1 conducts and the line L is discharged. The rectifier D4 and resistor R3 remove any positive charge remaining on the lower plate of capacitor C1 when the fault conditions are no longer present. Valve V1 may be a thyratron which will then be extinguished when ignitron I fires and removes its anode voltage.

Title: A sectional and collapsible rim for a tire retreading vulcaniser air bag
IPC: B29C33/76
Filed: 1953-08-17
Abstract: 725,096. Cores for retreading tyres. GENERAL TIRE & RUBBER CO. Aug. 17, 1953 [Aug. 23, 1952], No. 22677/53. Class 87 (2). A collapsible annular supporting rim for a tyre vulcanizer air bag comprises a series of sections substantially identical in size and shape and joined end to end, these sections having outer faces that form a circumferentially continuous air bag supporting face and end faces that abut at each joint to resist collapse of the rim, with links connecting the adjacent ends of the sections at each joint except one to provide a breakable joint, each link being pivoted at its ends to adjoining sections and certain of the links being extensible to allow the ring to be collapsed. The ring supports an air bag 10 so that it presses the tyre casing 1 to be vulcanized against the mould ring 3. Each section 11, preferably, of cast metal, has a concave rim face 13, a central rib 14 and flanges 12. The flanges and rim are concave at one end and convex at the other, thereby forming interfitting bearing faces 18, 19. The ends of the sections also have shoulders 20 which abut when the ring is in its supporting position so that its circular form is rigidly maintained. The pivots 16 of the links 15 are concentric with the bearing faces 18, 19 so that the links 11 can be swung about them to separate the shoulder 20 and collapse the ring. Fig. 6 shows the ring being collapsed at its breakable joint, the two adjacent sections being 11a and 11b. Instead of links 15 at this joint there are two locking plates 21 fixed inside the flanges 12 of the section 11a and projecting past its bearing faces. These projecting plates fit between the inner faces of the section 11b and assist in holding the rim rigid, Fig. 3. An opening 23 is provided in the section 11b for the valve stem of the air bag. The collapsed rim is placed in the uninflated air bag and the valve stem inserted in the opening 23 when the section 11b is in the position shown in full line in Fig.. 6. The sections are then pressed into the rim locking position and the air bag is inflated. After vulcanization the air bag is deflated and the sections 11a, 11b are pulled inwards to break the joint, which can be done by pulling on the valve stem. This inward movement involves the outward movement of some of the other sections 11, and to make this possible some or all of the links 15 are extensible, preferably being made of rubber.

Abstract: 1304407 Drying foodstuffs; heat pumps TERMOELECTRONICA GENIA LIMITADA 11 May 1970 [12 May 1969] 22700/70 Headings F4G and F4H Foodstuffs are dried in a chamber (not shown) by passing heated air (e.g. at 25‹ C. and 40% relative himidity) in a closed system around them, the air being heated by a heat pump system which utilizes the latent heat of condensation of the water vapour carried by the air and removed from the foodstuff during drying. Wet air A<SP>1</SP> (80% R.H.) leaving the drying chamber is cooled below its dew-point (15À3‹ C.) by drawing it through an evaporator E of the heat pump system by means of a blower V, so that the latent heat of condensation is supplied to the working fluid of the system to vaporize it, and water is removed at E<SP>1</SP>. The air (at 11À5‹ C. and 95% R.H.) is then passed through the condenser C of the system where it absorbs the latent heat of condensation of the working fluid, and attains its drying condition (25‹ C. and 40% R.H.). Since the air circulates in a closed system, the temperature tends to rise and the relative humidity to fall as drying proceeds. The temperature of the air is automatically controlled by means of a thermostat T in the air stream which controls solenoid valves Sp and Sa to divert the gaseous working fluid through an alternative condenser C<SP>1</SP> (exposed to the atmosphere) when the air temperature rises. The relative humidity of the air is automatically controlled by means of a hydrostat H g  which controls a solenoid valve Sg to pass some gaseous working fluid to the evaporator thus raising the temperature thereof (and hence the relative humidity of the air), when the relative humidity falls. A dehydrating filter F, an expansion valve X, and a needle valve H, are provided.

Abstract: 1426675 Marine lifesaving apparatus FRANCE ARMED FORCES MINISTER OF 21 May 1974 [26 June 1973] 22760/74 Heading B7U [Also in Division F2] Underwater escape suit, e.g. for escaping from a submarine or diving bell, consists of a canopy 120 which fits over the head and forms an air bubble for breathing, and a drag device 100 to reduce the rate of ascent in certain circumstances. For example, the device may be arranged to operate only on escape from below 180 metres, when a rapid ascent would carry a serious risk of air embolism. The drag device consists of a spring (see Division F2) which is compressed by water pressure acting on a piston. If a first predetermined depth (e.g. 180 metres) is exceeded a latch is engaged, so that when the escapee rises above a second predetermined depth (e.g. 80 metres) the spring expands to discharge a parachute from a container. The parachute may reduce the ascent rate for the last 80 metres from 3 m./sec. to 0À7 m./sec. The release depth may be adjusted by varying the position of the latching mechanism.
