Title: Improvements in radio direction-finding devices
IPC: G01S3/14
Filed: 1947-02-19
Abstract: 636,199. Radio direction-finding. PHILIPS LAMPS, Ltd. Feb. 19, 1947, No. 4820. Convention date, Feb. 26, 1944. [Class 40 (vii)] Relates to direction-finders of the type in which the signals received by two angularly disposed directive aerials are applied through separate receivers to an indicator. In such a system it is essential that the amplification and phase shifts of the two receivers are balanced and in accordance with the invention the balance is tested by periodically disconnecting the normal aerial outputs and connecting the two receivers to a common voltage source, means being included for adjusting the amplification and phase shift of at least one receiver. As shown in the Figure, the two crossed frame aerials 1 and 2 are connected through receivers 3 and 4 to the Y and X plates of the cathoderay tube 5 when the switches 8, 12 and 13 are in the operative position as shown so that the direction of the received signal is indicated by the angular position of the resultant trace but in the test position of the switches, the signal from aerial 2 is applied to both receivers, the outputs from which are then applied to the X and Y plates of an auxiliary cathode-ray tube 9 giving a linear trace at 45 degrees to the X and Y axes when the receivers are balanced. Any unbalance may be corrected by the amplitude and phase control 14. Alternatively, the test outputs from the receivers may be applied in opposition to a voltmeter, the receivers being balanced by first adjusting the phase control to give a minimum indication and then adjusting the amplitude control to give a zero indication. In a simplified embodiment the auxiliary indicator and the switches 12 and 13 are omitted, the test and bearing- indicating traces being then produced alternately on the cathode-ray tube 5 and if desired the test voltage may be obtained from the aerials 1 and 2 connected in parallel or from a separate source. The switches 8, 12 and 13 may be electronic switches of 'known form operating at a sufficiently high frequency to cause the traces to appear simultaneously.

Title: Light and stable thermoplastic base products made up of closed polyhedral cells, and a method of manufacturing the same
IPC: C08J9/04
Filed: 1948-02-18
Abstract: Thermoplastic polycellular products having closed polyhedral cells are obtained by making a reduced scale pattern of the desired shape, heating, introducing gas under pressure into the mixture forming the pattern at a temperature near that at which gelatinization commences, increasing the volume by 10 to 30 per cent by a reduction of pressure, gelatinizing by heating, cooling to ambient temperature, and then heating till the material softens sufficiently to expand and form a polycellular product.  The gas producing agent may be diazoaminobenzene or azoisobutyric acid dinitrile.  In examples: (1) polystyrol, (2) and (3) polyvinyl chloride, and (4) polyvinyl acetal, are treated together with an appropriate gas producing agent in the moulds described in Group V.

Patent GB-359345-A (GB)
IPC: A23F3/12
Filed: 1931-02-16
Abstract: 359,345. Tea-rolling machines. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. Feb. 16, 1931, No. 4885. Convention date, April 16, 1930. [Class 129.] The press covers of tea-rolling machines are provided with means whereby an increase of pressure in the tea container causes a reduction in the lowering movement of the press cover. The press cover 33 is carried by a spindle 1 threaded in a bush 3 which carries a flange 21. The bush has a pulley 5 with ratchet teeth in its surface, this pulley being rotated by a chain 4 to raise or lower the press cover. A pawl 7 co-operates with the ratchet teeth 6. The pawl slides in a, guide 12 and is operated by a rod 13 driven from a crank disc 11, so that the tea-rolling mechanism also rotates the pulley 5 step by step to cause the press cover to maintain the pressure on the tea as it decreases in volume by rolling. When a certain pressure, indicated by the spring 14, is reached, a release rod 19 tilts a lever 29<1> pivoted at 29 to bring a wedge 32 into the path of the ratchet 7, causing this to miss teeth 6, so preventing increase of pressure. A cam 20 on the disc 18 engages the end of the rod 19 and can be set by gears 24, 25 to act at various pressures.

Title: Improvements in and relating to fire-escape ladders
IPC: E06C5/38
Filed: 1938-02-18
Abstract: 505,058. Road-vehicle undercarriages and supports. HUMBOLDT-DEUTZMOTOREN AKT.-GES. Feb. 18, 1938, Nos. 5177 and 5179. Convention dates, Feb. 18, 1937 and April 12, 1937. [Class 108 (ii)] [Also in Groups XXI and X] Relates to vehicular fire-escape ladders which are provided with locking means for rendering the springing of the vehicle inoperative when the ladder is to be erected, and consists in the provision of a safety device which ensures that the frame supports of the vehicle cannot be lowered until the spring- locking means -has been engaged. This device may be associated with the unlimbering mechanism of a hose carriage, and a further safety device, in series with the first, may prevent actuation of the ladder gear before the frame supports have been lowered. As shown in Fig. 1, a hook 6 for engaging the axle 2 to lock the vehiele springs is controlled by a hand lever 11 or, automatically, by a rod 14 when a hose carriage 13 is unlimbered. When the lever 11 is rocked to engage the hook 6, a spring pin, not shown, engages a recess in the vehicle frame. Until the pin has engaged the recess, a stop member 31 controlled by the pin prevents actuation of the lever 16 which lowers the frame supports 15. As shown in Fig. 4, the lever 11 controls, through linkage 8, 22, 23, a stop. member 24 which lies. in the path of movement of a member 25 of the starting linkage 18-21 of the ladder-erecting gear. A similar stop member 35 is connected, by linkage 36-38, to the actuating lever 16 of the frame supports. In this arrangement, the ladder gear cannot be started until the supports 15 have been lowered, and this is only possible when the hook 6 has been engaged. The Specification as open to inspection under Sect. 91 describes also constructions in which actuation of the ladder gear is controlled only by the position of the spring-locking hook 6 ; in which the stop members 24, 35 act independently of one another and a separate member 35 is provided for each frame support ; and in which the stop members act on hydraulic ladder gear ; and a construction, Fig. 8 (Cancelled), in which the turntable 3, 4 is provided with a balanced anti-tilting device 43, 46, 47. The hook 6 is associated with a member 48 which acts, when the hook is disengaged as shown, to raise the turntable and lock the anti-tilting device inoperative, to avoid injury to the latter when the vehicle is travelling. By this arrangement, the anti-tilting device must be restored to operation when the hook 6 is' engaged with the axle 2 prior to erection of the ladder. The linkage 7-9 controls a stop member 31 which prevents lowering of the frame supports 15 until the hook has been engaged, and the linkage 37, 39 of the supports controls the rod 35 which prevents operation of the ladder gear. This subject-matter does not appear in the Specification as accepted.
