Title: Improvements in or relating to pump apparatus
Inventor: ALLEN GEOFFREY REX
IPC: A61M16/00
Filed: 1963-05-10
Abstract: 1,009,386. Bellows. MINISTER OF AVIATION. May 19, 1964 [May 10, 1963], No. 18579/63. Heading F1N. [Also in Division A5] Pump or breathing apparatus comprises a variable volume pumping chamber and a complementary variable volume delivery chamber, the pumping chamber being in connection with a continuous gas pressure supply and being alternately expanded by the gas pressure supply and contracted by a return mechanism, pressure in the pumping chamber being controlled by discharging the gas through a variable discharge valve whereby the pumping cycle of the delivery chamber is brought about by the changes in the volume of the pumping chamber in accordance with the changes in the gas discharge rate through the valve. The variable valve has a gas pressure chamber closed on one side by a diaphragm connected to an obturating member, the obturating member being biased to the closed position by the gas pressure in the chamber. This pressure is variable and is connected to the high pressure chamber of a regulator valve. The chamber pressure, which chamber may be fed with gas from the supply feeding the pumping chamber, is determined by the obturator of the regulator valve which obturator is biased to a closed position by a variably loaded spring, the loading being by a screw mechanism, by a cam and follower mechanism or by gas pressure which may be produced by the breathing cycle of a resuscitator. The pumping chamber is fed through a sonic orifice. In Fig. 1 the apparatus comprises pumping chamber 10, delivery chamber 14, gas inlet 12 and variable valve 13 connected to regulator valve 26. In use, gas from conduit 12 passes into chamber 10 forcing piston 19 to expel gas from chamber 14 to conduit 16. When the pressure in chamber exceeds that in the pressure chamber of the valve 13, valve 13 opens and gas escapes from the chamber 10 and plate or piston 19 is returned to its original position by spring 21. In Fig. 4 the apparatus comprises inspiratory cylinder 100, expiratory cylinder 105 with pumping and delivery chambers 102, 107, 101 and 106, and variable discharge valves 103, 108 connected to regulator valve 116 having pressure chamber 115 fed by gas via pipe 119 from main gas supply, the pressure in chamber 115 being determined by the breathing cycle of the person using mask 121 or by cam arrangement 120. The pumping chambers are supplied with gas via a sonic orifice. In use, as chamber 102 expands gas is fed to mask 123 via conduits 125, 124 and inspiratory valve 129, valves 127, 130 being closed at this time. Simultaneously chamber 107 expands and expels used breathing gas from chamber 106 through valve 131. On the opening of valves 103, 108, the chambers, 102, 107 contract, valve 129 closes, valve 127 opens allowing a fresh supply of breathing mixture to enter chamber 101, valve 131 closes, and valve 130 opens so that breathing gas is sucked from the lungs into chamber 106.

Title: Improvements in or relating to image pick-up devices
Inventor: SCHAGEN PIETER
IPC: H01J29/89
Filed: 1964-06-10
Abstract: An infra-red image pick-up device for night viewing utilizing the natural thermal radiation (infra-red radiation) of objects in a scene includes a target which comprises a transmissive material with a temperature dependent transmission coefficient for electromagnetic radiation of a given wavelenght, which arises from the presence of a steep absorption edge in the transmissive material, the spectral position of which is temperature dependent, and an infrared absorptive material which forms a thermal image of an object or scene in the form of local variations of the temperature of the target. The target may comprise evaporated ZnO as the absorption edge material, and besides providing a suitable absorption edge transmissive material the ZnO may also be used as a luminophor to provide the necessary incident scanning light by forming the target of ZnO mixed with SiO evaporated on a self-supporting transparent film of Al2O3, the target which is positioned in an evacuated glass bulb being scanned by an electron beam, Fig. 10 (not shown).  The SiO serves as an absorber of the infra-fed radiation and the ZnO layer is so deposited that the part of it nearest the adjacent glass wall of the bulb is efficient as an absorption edge filter, while the part of it furthest away from the wall is efficient as a luminophor.  Thus, the electrons in the scanning electron beam cause only the ZnO on one face of the target to emit electromagnetic radiation, this radiation then being transmitted by the ZnO on the other face in proportion to the temperature of that other face which is determined by the local infra-red radiation absorbed by the SiO.

Title: Method of and apparatus for electric welding by means of resistance
IPC: B23K11/24
Filed: 1924-08-12
Abstract: 220,628. Sciaky, D. Aug. 13, 1923, [Convention date]. Automatic circuit-breakers; magnetic blow-outs. -A switch for a spot-welding circuit is designed to interrupt the circuit after a predetermined interval has elapsed from the current reaching a definite value. The switch is set by downward movement of a rod 4, the lower end of which is 'bevelled and engages a roller 7 mounted in a lever 6, thereby turning the lever 6 and an associated lever 9 to close the contacts 10, 11. Further movement of the rod 4 causes its knob 12 to engage another rod 13 which is pressed downwards so that the reduced end 13a thereof is no longer adjacent to a nose 20 of the lever 6, thereby holding the switch closed against the action of a spring 21. A stud 15 on the end 13a presses on the part 16 of a pivoted sector 17 which is raised to the dotted position and held there against the action of a spring 27 by a brake biassed by a spring 26. When the welding current, which circulates in the windings of an electromagnet 25, exceeds a certain value, an armature 24 is attracted thereby releasing the brake 22 and allowing the sector 17 to fall at a rate dependent upon the extent to which the brake is released. Fall of the sector 17 causes the rod 13 to rise till its reduced end 13<a> comes opposite the nose 20 whereupon the switch opens. The springs 26, 27 are adjustable and a dash-pot device may be associated with the sector 17. The cores of the electromagnet 25 extends through the casing and serve as a blow-out device for the contacts 10, 11. An electrothermic device may be used in place of the electromagnetic device. The Specification as open to inspection under Sect. 91 (3) (a) states that the predetermined interval starts from the moment that the welding current has been established. This subjectmatter does not appear in the Specification as accepted.
