Title: Breech mechanism of guns
IPC: F41A19/37
Filed: 1942-12-16
Abstract: 581,981. Ordnance. SMITH, W. H. Dec. 16, 1942, No. 17898. [Class 92 (ii)] The breech block 1 of a gun is swung about its pivot 2 by an operating arm 12 interconnected by link mechanism with a locking device 5 and a cocking device, the arrangement being such that in the opening movement the arm'first releases the locking device and subsequently moves the breech block, while during the closing movement the arm first moves the breech block and subsequently actuates the locking and cocking devices. As shown in plan in Fig. 1 and in sectional plan in Fig. 2, the arm consists of upper and lower links interconnected by a handle 16 and pivoted to the breech-block which in turn is pivoted at 2 to a casing 4 surrounding the breech end of the barrel 3. Arms 13 integral with the arms 12 are pivoted to links 15 the rear ends of which are pivoted to a pin 14, the latter also forming the central pivot for pairs of toggle links 10, 11. Links 11 are pivoted to the breech,block and links 10 to rearward extensions of the locking device 5. Upon moving the handle 16 in the direction of the arrow c the links 10, 11, move towards the barrel and thus release the locking device, the breech block remaining stationary until a lip 19 at the slotted end of a lever 17 pivoted to the upper arm 13 moves to a position where it can slide over the arcuate edge of a fixed plate 20. During the return movement the breech block is first moved about its pivot, further movement of the handle serving to return device 5 to its locking position and to retract the firing pin 23. The latter action is effected by an arm 21 mounted on the pin 14 and adapted to engage a circular rack 22 on an extension of the firing pin. The latter is held in the retracted position by a spring-urged pawl 24 and the release of the pin is effected by a lever 25 attached to the arm 21 the latter when moved being adapted to engage and lift the pawl from its engagement with the rack 22. The breech-block may be fitted with a member 34 recessed at 29 for engaging the flange of a projectile and carrying spring-pressed plungers for pressing such flange against the rear end of the barrel.

Title: Improvements in or relating to time-cycled respirators
Inventor: MCKENZIE HUGH WILLIAM GORDON
IPC: A61M16/00
Filed: 1962-05-10
Abstract: 970,626. Respiratory apparatus. PYE Ltd. May 7, 1963 [May 10, 1962], No. 17975/62. Heading A5T. Time-cycled artificial respiration apparatus in which gas from an automatically contracted and expanded bellows is caused to be inhaled and exhaled by the patient, includes sensing means which operates an alarm if the expansion or contraction of the bellows exceeds predetermined limits. Normally closed sensing switches S1, S2 are operated by the gas reservoir of the respirator in response to expansion or contraction of the reservoir beyond predetermined limits. The sensing switches are connected in a circuit including a battery 1, which operates the timing control of the respirator, and a reversing switch S3. On depressing the reversing switch, current flows via diodes 3, 4 through a slugged relay 2 which closes a switch S4. Release of the switch S3 permits current to pass through the relay 2 via diodes 5, 6 and switch S4 is maintained closed. The relay also closes switch S5 so that an indicator lamp 10 indicates normal operation of the respirator. The alarm circuit which includes audible alarm 13 and lamps 14, 15 is normally operated by a separate power source 8, e.g. mains supply, which energizes a relay 9 to operate a switch S6 to disconnect the battery from the alarm circuit and to close a switch S7 to maintain the indicator lamp 10 energized. If the power source 8 fails, the lamp 10 is extinguished and the alarm circuit is connected to the battery 1 through the switches S5 and S6. If either of the sensing switches S1, S2 is opened the relay 2 is de-energized so that switch S4 opens and the alarm circuit is energized via the switch S5. Temporary operation of either switches S9 or S10 energizes the relay 17 to operate a switch S8 which cuts out the audible alarm. Capacitors 20, 21 and a resistor 22 may be connected with the sensing switches to delay the de-energization of relay 2 in the event that either of the sensing switches are opened for a short period only so that the alarm is not operated unless the sensing switches are opened for more than a longer predetermined period. Specification 914,343 is referred to.

Abstract: 1,223,704. Semi-conductor devices. HITACHI Ltd. 17 April, 1968 [19 April, 1967; 4 May, 1967], No. 18194/68. Heading H1K. One or more semi-conductor device bodies with PN junctions terminating at one major face and junctionless semi-conductor terminal bodies are disposed in spaced relationship with their major faces in two parallel planes. A beam lead in one plane electrically connects one device body with another or with a terminal body while a connection formed on an insulating support disposed adjacent the other plane is connected to said other device or terminal body. A typical assembly (Fig. 3) is prepared from a silicon wafer by diffusing through oxide masking to form the desired devices at at least one face and then evaporating or electroplating on aluminium or gold 24 to form electrodes which are interconnected by heavier deposits of aluminium, chromium or molybdenum constituting beam leads 20, 21. Isolation of the elements is effected by subsequently etching away the silicon at 26, using photoresist techniques. The assembly is finally mounted by soldering contacts 31 on the terminal bodies to metallized tracks 32 on ceramic base 21. As shown the lower faces of the device bodies carry an insulating layer but they may if desired be connected to tracks on the substrate to provide external connections or interconnections. Gold or solder balls may be used to form connections to the metallization on the substrate which may alternatively consist of an oxide coated polycrystalline semi-conductor material. To reinforce the structure a glass or resin layer may be formed over the beam leads. The two levels of interconnection afforded by the invention are particularly useful where interconnections need to cross one another.

Title: Oriented polyarylsulphone film
Inventor: JENNINGS BRIAN EDMUND
IPC: C08L67/00
Filed: 1964-05-01
Abstract: 1,106,367. Polyarylsulphone films. IMPERIAL CHEMICAL INDUSTRIES Ltd. 26 April, 1965 [1 May, 1964], No. 18228/64. Heading B5B. An oriented film of a polyarylsulphone is formed of repeating units of the formula -Ar-SO 2 - where Ar is a divalent aromatic residue which may vary from unit to unit in the polymer chain, and in at least some of the units Ar is derived from a compound of formula (where Z is -O-, -S-, or the residue of a 4,4<SP>1</SP>-bisphenol) and in any other units Ar is similarly derived from benzene, diphenyl, or a polynuclear aromatic hydrocarbon containing not more than two aromatic nuclei so that in the divalent aromatic residues containing two benzene rings each benzene ring bears one of the valencies and one or more of the hydrogen atoms bound to aromatic rings may be replaced by halogen atoms or alkyl or alkoxy groups and a minor proportion of the -SO 2 - links may be replaced by -CO- links. The residues Ar may be derived from diphenyl ether or diphenyl sulphide, and optionally also in minor proportion from diphenyl. Films may be made by compression-moulding, melt-extrusion, calendering, or casting from a solution of the polymer in a suitable solvent e.g. nitrobenzene or dimethyl formamide. In moulding or extrusion, temperatures of at least 300‹ C. are required to obtain the material in a sufficiently mobile form, but temperatures above 330‹ C. may cause thermal degradation. Orientation may be effected by stretching, suitably at 240-260‹ C. A preferred oriented film is made from a polyarylsulphone in which the benzene rings in the polymer chain are essentially all -para. The stretching method used depends largely on the process used for forming the film. Longitudinal stretching may be effected by the use of feed and draw rolls, and the film may then be transversely stretched by tentering. Alternatively tentering alone may be employed using a tenter in which the pairs of clamps diverge laterally while the distance between adjacent pairs is also increased, thus simultaneously stretching the film both laterally and longitudinally. Alternatively, tubular films may be made by melt-extrusion and drawn by passage between two pairs of nip rolls while simultaneously inflated, in known manner.
