Abstract: 469,388. Unit air conditioner ; refrigerating. NEWCON INDUSTRIES, Ltd., and YARROW, W. S. Nov. 23, 1935, No. 32538. [Class 137] [Also in Group XIII] A self-contained airconditioning apparatus includes an absorption refrigerating unit the evaporator of which is utilized to cool the air in a room, while the absorption heat is utilized to condition the same air. A cabinet 1 is made with partitions forming passages 2, 4, 3, and 6 in which are situated a heater 7, an absorber 8, a condenser 9, and an evaporator 10 respectively. Air drawn through an opening 13 by a fan 14 passes, with the flaps 18 and 19 in the position shown through passages 3 and 4, and part is heated by the absorber and mixes with the air from passage 3 on the way to the condenser 9 and outlet 17 to the room or to the outside. The air in the passage 5 passes over the fins of the evaporator 10 to the outlet 15 into the room. With the flap 19 open, the air is heated by the absorber, and cooled to deposit excess moisture before use.

Title: An extensible arm assembly for a spacecraft or a satellite
IPC: B64G1/22
Filed: 1969-06-27
Abstract: 1,268,841. Spacecraft unit. MESSERSCHMITT - BOLKOW BLOHM G.m.b.H. 27 June, 1969 [8 Oct., 1968], No. 32652/69. Heading F4U. [Also in Divisions H1 and H4] An arm assembly extensible to a substantially planar position and serving as an aerial or reflector or for supporting solar cells or a spacecraft or satellite, is stored before use by folding and/or winding close to the exterior of the spacecraft. The assembly comprises a number of rigid parts connected together so as to fold and forms a main extensible arm, with further lateral arms provided which fold on to the rigid parts and extend at a right angle to the main arm. In one embodiment, each of two main arms of a rectangular spacecraft is divided into parts 3, Fig. 2, of equal length which are connected by hinges 4 and which are openable by pre-stressed springs 5. To each of the parts 3 is fixed on opposite sides, by securing clips 8, lateral arms 6 each with two stabilization tubes 7. Tubes 7 are made of laminates of glass fibre and gelatine and rendered flexible and foldable by impregnating the laminates by water or glycol. Polyamide tubes (15, Figs. 4, 5) are inserted into tubes 7 to accommodate pressurized gas which effects unfolding of the lateral arms. Solar cells (not shown) are mounted on a flexible polyimide film 9 which is stretched between the tubes 7 and inflatable polyamide spacing tubes 10 and which also surrounds tubes 7 to prevent the impregnating agent from freezing but allows its evaporation in space with consequent stiffening of the tubes 7. Each of the lateral arms on either side of the part 3 is folded in zig-zag fashion on to part 3 to fit into box-like compartments as shown in Fig. 3. The arms 3 fold on to themselves, Fig. 1 (not shown). In another embodiment the main arms, instead of being folded, are wound round the exterior of an octagonal spacecraft (Fig. 6, not shown). In a further embodiment, (Figs. 7, 8, not shown), the lateral arms are folded down in interleaved formation on the same side of each of three main arms and wound round the exterior of the spacecraft. In the final embodiment, (Fig. 9, not shown), each extending lateral arm forms a single cohesive structure, the arms again folding down in interleaved fashion and the main arm being finally wound on to itself, (Figs. 10, 11, not shown).

Abstract: 326,222. Mathieu, G. A. Nov. 8, 1928. Keying systems; thermionic amplifiers and generators.-In a high-speed telegraph transmitter, the transmitter during movement of the key is maintained in the condition last set and " key clicks " are eliminated by the use of a push-pull circuit. The figure shows an oscillator V1 driving a push-pull pair of valves V2, V3 the grid circuit of which includes a condenser C4 for maintaining the potential between marking and spacing impressed by the relay RL. The output circuit L3, C5 is tuned to the drive frequency and thus short-circuits harmonics. In a modification a centre tapped output transformer is employed which, if electrical symmetry is maintained, will eliminate the " key clicks."

Abstract: 1,126,086. Local viewing by scanning ; cathode-ray tube operating circuits. PHOTO ELECTRONICS CORP. 25 July, 1966 [18 Feb., 1966], No. 33323/66. Addition to 1,125,847. Headings H4F and H4T. The brightness and contrast of the picture produced by cathode-ray display tube 10 of the system for examining colour photographic negatives described in Specification 1,125,847 are stabilized automatically by an arrangement in which a photo-resistor 26 responds to light from a white border 24 which is displayed around the picture area 22 and controls a circuit to vary inversely in appropriate ratio the potentials applied to the first and second control grids 14, 16. Photoresistor 26 forms part of a bridge circuit 26, 30, 32, 34, the unbalance voltage of which is detected by differential amplifier 40, 42 and applied through amplifiers 44 and 46 to control the potential of grid 14. This part of the circuit stabilizes the picture brightness by stabilizing the white level represented by border 24. A voltage varying inversely with the voltage applied to grid 14 is derived across resistor 47 in the emitter circuit of amplifier 46 and applied to differential amplifier 50, 52 where it is compared with voltage applied to grid 16 a fraction of which is obtained from potentiometer chain 66, 68, 70. The unbalance voltage controls the voltage of grid 16 by way of amplifiers 54, 56 and stabilizes the picture contrast. In the particular example described, the voltage variations applied to grids 16 and 14 are in the ratio seven to one. The picture signal is applied to the cathode 12 of the tube via amplifier 18 and has its D.C. level stabilized. One of resistors 30, 32, 34 may be made variable as a manual brightness control.

In an aircraft provided with a bay, for a bomb or other missile, with an opening at the bottom which is closed by a pair of longitudinally-extending doors, the meeting edges of the doors are supported, both fore and aft of the bay, by levers movable angularly to open the doors, and the remote edges of the doors are guided so as initially to move to a position which is clear of the bay opening and then to slide up the outside of the body skin while the doors are being opened. Fig. 2 shows a crosssection of the bomb bay with the doors open. The meeting face of each door 13, 14 is connected at each end to the long arm of a bell crank lever 17, the short arm of which is connected, with lost motion, to the movable element of a jack 23.
