Title: Improvements in the stabilisation of poly-isobutylene
IPC: C08K5/375
Filed: 1936-09-28
Abstract: Polyisobutylene is stabilized against mechanical treatment and ageing by an addition, up to about 1 per cent of a cyclic amine or a phenol. The added substance may contain the amino or aromatic hydroxyl groups more than once, or simultaneously.  Specified additions are phenyl-beta-naphthylamine, alphanaphthylamine, and para-monobenzylaminophenol.  In an example, polyisobutylene is kneaded with 0,1 per cent of para-monobenzylaminophenol.

Title: Improvements in or relating to program controlled electronic computers
IPC: G06F15/02
Filed: 1965-03-01
Abstract: 1,103,385. Digital electric calculating apparatus. ING. C. OLIVETTI & C. S.p.A. 1 March, 1965 [2 March, 1964; 2 Jan., 1965], No. 8684/65. Heading G4A. A programme-controlled computer comprises manually-operable control keys under the control of which an instruction can be entered in the instruction staticizer and executed independently of the stored programme control. The computer described is that of Specification 1,103,384 but additionally means in the form of programme-bearing cards are described for entering a programme into the computer memory. Programme card.-Each programme card can store the contents of five memory registers I, J, Z, D, E, the registers I, J being for instructions, the registers Z, D, E, being splittable into two, can each store a 22-digit number or two 11- digit numbers or 24 instructions or an 11-digit number and 12 instructions. When a programme has been entered in the memory, one of four subroutine keys V1-V4 may be depressed thereby causing the computer to execute the corresponding subroutine. Each card 150 (Fig. 9, not shown) consists of a flexible sheet having on one face a strip of magnetic material as a recording track. The card is inserted in an inlet slot 113 and driven by rollers 116, 117 to an outlet slot 114. When the leading edge of the card reaches the sensing magnetic head 129, a switch 137 is actuated and remains closed until the trailing edge of the card has passed the head. The front of the card bears a visual statement or symbol of the subroutine in the programme on the card corresponding to the various subroutine keys V1-V4. The recording track on the card contains the contents of the five memory registers I, J, Z, D, E. Each 8-bit character read from the card is entered into a buffer shift register K and while four blank bits are being scanned, written into the memory. One or more of the four blank bit positions may be used for checking purposes, for example, a simple parity check bit may be recorded. The programme card may also be used to record data. When reading from the card, the bits read out trigger a monostable circuit OS (Fig. lla, not shown) to produce shift pulses for the shift register K, the output 14 of the shift register being connected to the registers to which it is required to transfer the data read from the card.

Title: Improvements in System and Process for the Indirect Electrochemical Combination of Air and a Reformable Fuel
IPC: H01M8/06
Filed: 1967-02-24
Abstract: 1,174,973. Fuel cells. GENERAL ELECTRIC CO. 24 Feb., 1967 [25 Feb., 1966], No. 9000/67. Heading H1B. In a fuel cell consuming H 2  generated by reforming a mixture of H 2 O and a reformable fuel, H 2 O consumed in the reformer 21 is replenished with water produced in the fuel cell and heat is exchanged upstream of the anode 9 between the reformate, the electrolyte and air to partially equilibrate the reformate and the electrolyte at a lower temperature. As shown in Fig. 1 H 2 O from source 15 and fuel from source 17 are reformed and the reformate passes through heat exchanger 32 which serves to vaporize the inflowing mixture, purifier 31 which removes CO and heat exchanger 55 where it is indirectly equilibrated with electrolyte 5 via a coolant and heat exchanger 13, and cooled by air from supply line 51, before passing H 2  to chamber 3. The supply of H 2  to the anode 9 is maintained at a constant rate by means of control 101 which alters valve 49 to increase the rate of H 2  recirculation as the voltage decreases. Air from supply 51 is heated in heat exchanger 63, optionally mixed with hot air from exchanger 55, humidified in humidifier 67 and supplied to cathode. 11. The exhaust gases from cathode 11 pass through heat exchanger 63 and also through refrigerator 77 whence H 2 O condensed is supplied to source 15.

Title: High altitude suit and mask oxygen regulator
IPC: A62B9/02
Filed: 1958-04-01
Abstract: 861,720. Fluid-pressure servomotor-control systems ; valves. BENDIX CORPORATION. April 1, 1958 [April 1, 1957], No. 9007/58. Class 135. [Also in Group XXI] An oxygen regulator apparatus for simultaneously regulating the flow of oxygen to a breathing-mask and to an inflatable suit includes means for supplying oxygen to the mask in response to inhalation demand when the ambient pressure exceeds that corresponding to a predetermined altitude and means for supplying oxygen to the mask and to the suit at pressure when the ambient pressure is below the predetermined level, the pressures in mask and suit bearing a fixed ratio to one another. Oxygen enters the regulator through an inlet 16 via a pressure-reducing valve 11 actuated by a bellows 12 which is responsive to the pressure in the chamber 14. Oxygen passes to the mask through a valve 18, nozzle assembly 26 and outlet 28. A reduction in pressure in the outlet caused by inhalation affects the chamber 30 through the opening 29 and the diaphragm 34 flexes under the pressure in chamber 35. A boss 36 at the centre of the diaphragm bears on the end of a lever 37, pivoted at 38 and operates the lever 39 pivoted at 40 which opens the valve 18. The oxygen is diluted by air admitted through a valve 66 operated by a bellows 67 which closes the valve as the ambient pressure decreases. An overriding manual control 68 is fitted. When the ambient pressure in chamber 87 falls to that at which oxygen is required to be fed to the mask at pressure then a bellows 88 expands, compresses a spring 93 which bears on a lever 90 and through the spring 92 opens the valve 46, which allows oxygen to flow into the chamber 47 and flex the diaphragm 56 upwardly. This diaphragm is secured to the tube 60, the lower end of which forms the valve 50 and allows oxygen to pass through the tube 60 and to the outlet 28. If the mask pressure exceeds the required value the diaphragm 34 moves downwards and closes the valve 18 and subsequently bears on the centre 62 of the diaphragm 56 and shuts the valve 50. Inflation of the suit commences when a valve 70 opens because the thrust on a diaphragm 81 due to a spring 83 and the pressure in chamber 47 overcomes the thrust due to ambient pressure. Until inflation commences the suit is vented to atmosphere through a valve 75 which is closed by a diaphragm 76 as ambient pressure decreases. As ambient pressure varies in flight, oxygen flows to and from the suit and the chamber 47, oxygen exhausted from the suit passing to the mask. The ratio between the suit and mask pressures is determined by the diameters of diaphragms 56 and 34 respectively. A relief valve 65 prevents excessive pressure in the mask. In a modification the tubular element 60 is without the opening 59 and instead has a side opening connected with the atmospheric space 35. Specification 786,842 is referred to. Reference has been directed by the Comptroller to Specification 804,858.

An escapement comprising a driven escape wheel 5, Fig. 1, and a pair of pivoted pallets or like members 7 arranged to engage the escape wheel teeth at spaced-apart locations and control the movement of the escape wheel, is characterized in that the pallets 7 are interconnected by a lost motion mechanism so that as one pallet is forced out from a tooth the other is rocked to engage a tooth, the escape wheel thereby being constrained to move in step-by-step manner without the use of a controlled oscillator. The pallets 7 are pivoted on spindles 8 and are connected to levers 9, 10 respectively. The lever 9 has a pin 11 which is embraced by the forked end 12 of the lever 10 so that as one pallet is moved outwardly by a tooth 5a of the escape wheel 5 the other pallet is moved to engage a tooth. Regulation is effected by limiting the movement of one of the levers 9, 10 by two adjustable screws 13. In a modification (not shown) the spindles 8 are in a plane parallel to the plane of the escape wheel.
