Title: Improvements in antenna system
IPC: H01Q9/38
Filed: 1946-09-06
Abstract: 631,324. Aerials ; aerial coupling arrangements. BENDIX AVIATION CORPORATION. Sept. 6, 1946, No. 26794. Convention date, Sept. 7, 1945. [Classes 40 (v) and 40 (vii)] A wide band aerial comprises a cylindrical member and a conical member in co-axial relationship, the apex of the conical member, which is constituted by a plurality of rod-like conductive members uniformly distributed around the axis of the aerial, being directed towards the cylindrical member. The aerial is supported by a mast structure 10, Fig. 1, which may be formed from conductive or non-conductive material and the upper end which is closed by a conductive plate 18 is arranged to support, by means of an insulating collar 11, a conductive cylindrical member 12, the length of which is #/4 at the mean operating wavelength. The member 12 is closed at its lower end by a conductive plate 15 provided with a central aperture from which the outer conductor 16 of a co-axial line 17 extends upwardly into the member 12, the inner conductor 23 being connected to the periphery of the plate 18. Departure of the line 17, which forms an impedance matching element, from a length of #/4 is compensated by the capacity existing between the cylindrical and conical members, i.e. between the plates 15 and 18. This latter plate is also provided with a central aperture which locates the outer conductor 19 of a co-axial feed line 20, the inner conductor 25 of which is connected to the periphery of the plate 15. Suitably attached, e.g. by fastening members 13, Fig. 2, and symmetrically arranged about the periphery of the plate 18 are conductive rod members 22 each of length #/2 at the mean operating wavelength and each forming an element of a conical surface, optimum results being obtained when the angle between the rod members and the axis of the system is approximately 45 degrees.

Title: Improvements in and relating to shock absorbers
IPC: F16F9/10
Filed: 1937-10-06
Abstract: 490,177. Hydraulic shock-absorbers. ELEKTRONMETALL GES. Oct. 6, 1937, No. 27107. Convention date, Nov. 16, 1936. [Class 108 (iii)] In a shock-absorber comprising a lower fluid-pressure cylinder 5 adapted to slide in the annular space separating an upper cylinder 1 and concentrically-arranged plunger 2 secured to the cylinder 1, the interior of the cylinder 1 is separated from the cylinder 5 by an annular disc 6 extending between the plunger and the cylinder 5 and leaving a shock-absorbing, liquidrestricting passage, abutments 3, 4 for the disc being provided respectively on the plunger and cylinder 5. As shown springs 7, 8 bear on either side of the disc, and, in operation, on compression of the shock-absorber, as the plunger moves into the cylinder 5, the pressure of the fluid forces the disc upwardly against the stop 4 compressing the spring 7, fluid passing into the cylinder 1 through the annular liquid-restricting passage between the disc and plunger. By forming the plunger with a variable crosssection, the hydraulic damping action may be regulated. When the spring is fully compressed, the disc is driven downwardly thus increasing the hydraulic resistance which is augmented by compression of the spring 8. Instead of the spring 7, an annular flange may be provided on the plunger to engage the disc when the shock-absorber is compressed a predetermined amount.

Abstract: 1504395 Heating and cooling buildings DAIKIN KOGYO CO Ltd 27 June 1975 27340/75 Headings F4U and F4H In a central heating or cooling system including indoor coils 11 and an outdoor coil 3 operable to achieve heating and/or cooling of a space, a refrigerant acting as a heating medium in the heating mode is circulated from a heat exchanger 15 wherein it is heated and vapourized by a heat source, e.g. hot water, at a temperature above the outdoor ambient air temperature, and a four-way valve 2 to a circulating pump or compressor 1, to the indoor coils 11 where it is condensed and then returned directly to the heat exchanger 15, by-passing an outdoor coil 3 of the heat pump circuit. The flow resistance of the refrigerant in the circuit between the indoor coils 11 and heat exchanger 15 is limited, as by very low pipe line resistance or capillary tube 25 presenting little resistance such that the refrigerant pressure at the entrance of the heat exchanger 15 is higher than the saturation pressure corresponding to the air temperature around the exchanger and no expansion means are used. As a result the compressor 1 operates at higher pressure than a conventional heat pump and the specific volume of refrigerant vapour drawn in so small as to enable it to operate with increased volumes, reduced compression ratio and reduced power consumptions compared with conventional compressors. By the utilization of an outdoor coil 3, expansion means 12, a by-pass circuit 31 for the expansion means and reversal flow means, the apparatus may perform a cooling operation utilizing refrigerant piping and the indoor coils 11 acting as evaporators. The apparatus may also be utilized to heat a water supply.

Title: Hydraulic device particularly for actuation by vehicles
IPC: F42C7/06
Filed: 1951-11-21
Abstract: 748,692. Land mines. COMPAGNIE GENERALE POUR L'EQUIPMENT AERONAUTIQUE. Nov. 21, 1951 [Dec. 2, 1950; Jan. 11, 1951; April 27, 1951; Aug. 23, 1951]. No. 27360/51. Class . 9(2) [Also in Group XXVIII] A hydraulic device for the firing of an anti-tank mine comprises a flexible tube 1 containing a liquid which actuates the device when the tube is crushed, as by the tread of a tank, over a sufficient length to force enough liquid through a constriction 50 into a receiving chamber. As the liquid enters the lower chamber of a cylinder 6 it raises a piston 7, which, through a trigger 12, releases a firing-pin 13. An orifice 10 in. the piston 7 allows for slow movement of soil in Which the tube is embedded or for changes in ambient conditions. Actuation beneath a vehicle can be ensured by employing two short tubes on either side of the device. The constriction 50 avoids actuation by shock waves from bombs and shells exploding in the vicinity. In an alternative construction, Figs. 8 (not shown), 10, 11, a mine is fired by a charge which is ignited when a string 124 is pulled to the right by a release member 116 as it moves to 116' (Fig. 14). This release member is biased by a rubber ring 119 to an arming member 118, but unable to move until tripped by the full movement of the centre part 114 of a blade 113, normally held down by a rubber ring 127. Liquid from tubes 107, 108. when simultaneously crushed by a vehicle passing directlv over the mine, distends two bladders 111. 112 to produce full movement of 114. If only one tube is crushed, the blade rises on one side only (Fig. 12, not shown) and the mine is not fired. When a vehicle passes over the mine at an angle to the two tubes, so that 107 is crushed before 108. a check valve 109 delays escape of the liquid from bladder 111 and the mine is fired. The device may be rendered safe at anv time by moving the arming member 118 to the left, relieving the rubber ring 119. Various sections of the tube are described and illustrated which prevent an oblong tube from expanding vertically at points where it is not crushed. or which facilitate sideways expansion of a round tube by providing pockets of air on both sides. These tubes allow the tube to perform properly when buried in a trench. A machine is described for forming a preferred tube. Fig. 29, which tube has liquid in the centre 307, and air in the outer spaces 306, 308.
