Title: Improvements in or relating to radio transmission and reception
IPC: G01S7/03
Filed: 1943-08-27
Abstract: 589,958. Radiolocation ; wireless transmitting and receiving apparatus. COCKCROFT, J. D., and ASHMEAD, J. Aug. 27, 1943, No. 14056. [Class 40 (v)] In a short-wave signalling system, particularly a radiolocation system, employing a waveguide 1 acting directly as an aerial or associated with a reflector 6, a toroidal cavity resonator 7 is connected in shunt with the guide through an aperture in the wall of the guide and acts normally to block transmission, but can be detuned to permit transmission by a switching voltage applied to an electrode 9 associated with an annular gap 7A enclosed in an envelope 8 containing an ionizable gas. In a radiolocation system as described in Specification 582,419, comprising a wave guide having two branches 2, 3 terminating in the focal plane of reflector 6 at equal distances from the focus, resonators are associated with each branch and are excited alternately. The assembly may be used for transmission as well as reception, the energy of the pulses from transmitter 16 being sufficient to ionize' both resonators independently of the switching voltages. In this case, a further resonator 18 is connected in series between guide 1 and receiver 12 to block the receiving branch 17 during transmission. The aperture in the resonator is rectangular with its shorter dimension lying in a crosssection of the toroid. The corresponding aperture in the wall of a rectangular wave guide has its shorter or longer dimension parallel to the length of the guide according as the resonator is fitted to the wider or narrower face of the guide. Iris diaphragms 15 inserted where shown provide matching impedances. Specification 589,023 also is referred to.

Abstract: 910,703. Knitting-machines. SINGERFIDELITY Inc. April 22, 1960, No. 14160/60. Class 74 (2). The dial 2 of a cylinder-and-dial machine having dial needles 4 operated by swinging jacks, is rotated in synchronism with the cylinder of the machine but is adapted to be shogged relatively to the cylinder to vary the needle spacing. The mechanism for driving the dial comprises a dial shaft 17 driven by a spur gear 33 through a span gear 32 freely mounted on the shaft 17. An arm 36 is pivotally mounted at 37 on gear 32 and is provided with a central bore 57 through which the shaft 17 freely passes and of such dimension to allow movement of the arm 36 without engaging the shaft. A collar 39 is secured to the shaft 17 and is coupled to the arm 36 by a stud 42. The drive from the gear 32 is therefore through arm 36 stud 42 and collar 39 to shaft 17. On the upper end of the shaft 17 a sleeve 72 having a conical lower surface 76 is slidably mounted and is adapted to be actuated according to the dictates of a cam drum to engage the conical surface 76 with a shoe 58 secured to the arm 36 so as to cause the arm to pivot, whereby the collar 39 and shaft 17 are partially rotated to vary the setting of the dial without interfering with the normal drive. When dial shogging is not required the gear 32 can be secured directly to the shaft 17. Specification 910,704 is referred to.

Title: Improvements in servomechanisms
IPC: B64C13/00
Filed: 1963-04-10
Abstract: 1,025,707. Automatic speed control. SPERRY RAND CORPORATION. April 10, 1963 [April 10, 1962], No. 14316/63. Heading G3R. In a servo-system having a pair of normal signal channels, each channel has components in common with a standby channel which duplicates the function of the other normal channel when errors signals exceed a predetermined value. As shown, A.C. signals representing error in the Mach number at which an aircraft is flying are derived from a measuring unit 13 and applied through demodulator-modulator shaping circuits 20, 34 and amplifiers 21, 35 to phase-sensitive discriminators 16,17 respectively. When the error is positive and exceeds a value determined by the bias of one output stage 23 of discriminator 16, the output from stage 23 operates a relay 52 to energize a clutch 53 and start a motor 54. Under these conditions motor 54 adjusts an elevator trim tab 11 so that the elevators 12 are raised and Mach number corrected. Feedback signals dependent on the elevator position are derived from a pick-off 15. If the error exceeds a greater value, determined by the bias of an output stage 42 of discriminator 17, the output from this stage operates an indicator 45 and also assists in the operation of relay 52. The output of stage 42 is also applied to a resistancecapacity network 44 so that if the greater error persists due to a fault, it is effective to operate a warning lamp 49 and a relay 47 to interrupt the output from stage 23 which may be unreliable. Other outputs from oppositely polarized stages 26, 40 of discriminators 16,17, together with associated relays and indicators, operate in a similar manner to produce and safeguard operation of the elevators in the reverse direction to correct negative errors in the Mach number when clutch 56 is operated.

Title: Combined inflating, deflating and gauging device for pneumatic tyres
IPC: B60S5/04
Filed: 1931-05-15
Abstract: 369,069. Pneumatic tyre pressure gauges. SCHRADER'S SON, Inc., A., 470, Vanderbilt Avenue, Brooklyn, New York, U.S.A.-(Assignees of Wahl, J. ; Cambridge Road, Rosedale, Queens, New York, U.S.A.) May 15, 1931, No. 14443. Convention date, Aug. 2, 1930. [Class 106 (ii).] Comprises a c o m - bined inflating, deflating and gauging device for pneumatic tyres and consists of a coupling member, means for connecting the coupling member with a tyre valve, a pressure gauge, a source of fluid pressure, means for selectively connecting the tyre valve with the source of fluid pressure or with the gauge, and independently operated deflating means for venting the tyre. The part g is screwed to the supply hose, while the other end of the device is connected to the tyre nozzle by a readily detachable chuck device having a valve depresser. The gauge C is at once in communication with the tyre via the bore of the tube B, the passage g<9>, the space surrounding the sleeve c and the groove c<5>. The gauge piston c<15> is moved against its spring c<6> and the rod c' is moved outward the end reading against the scale c<9>. If the pressure is insufficient, the trigger N is operated. This trigger swings about the pivot n<1> and the pin n<2> moves the tube B down. The end of this tube depresses the valve H normally held closed by the supply pressure, fluid under pressure passing through the valve and the bore of the tube to the tyre. At the same time, the gauge is vented via the passage g<9> the space around the tube B between it and the barrel g<6> to the atmosphere. When the trigger is released the gauge is once more connected as before to the tyre. Should the indication be too great, a valve e<x> is depressed by the hand push E and air is vented to the atmosphere through the opening e<3> until the desired pressure is reached. For adjusting the zero of the gauge, the rod is made in two parts, the upper one being screwed at the lower end to enter a split screwed sleeve c<11> the lower end of which is squared. To adjust the zero, the rod is depressed against its spring until the squared end enters a squared socket on the cap c<4> when the rod is turned by a screw-driver engaging slot c<14>.

Title: Improvements in the production of steel and alloys
IPC: C22B5/04
Filed: 1941-11-14
Abstract: A product containing 90-95 per cent. Fe3O4 is obtained by heating thin sheet steel scrap from coach building or tin plate manufacturers to 1,000-1,200 DEG C. for 20 minutes to 2 hours in an oxidising atmosphere.ALSO:In making steel by the exothermic reduction of iron oxide by a reagent such as aluminium, there is added to the charge a material, such as a nitrate, chlorate, or perchlorate, or a mixture of these, with which aluminium &c. reacts at a lower temperature than with iron oxide, the total amount of aluminium &c. being not substantially more than that required to reduce the iron oxide, and the nitrate &c. being in such quantity as to ensure the formation of a sufficiently liquid slag.  Additional slag forming materials such as lime, fluorspar, and sodium carbonate may be added.  Sodium carbonate may be compressed into bricks and preheated bricks added from time to time.  The charge may also contain metal which is melted by the heat evolved, and this metal may also be preheated and added alternately with additions of the reaction charge.  The aluminium may be used in the form of commercial aluminium alloy containing 90 per cent. or more of aluminium, with copper, nickel, zinc &c.  Tin should be absent, and silicon low; or excess silicon may be reduced by the means described in Specification 568,315.  If alloying elements such as chromium, nickel, or vanadium are required in the product, they may be added as metals, scrap, ferro-alloys, or oxides, additional aluminium being added in the case of oxides.  After completion of the main reaction, the product may be refined by further reaction with an oxide, or with a mixture of silico-calcium, sodium carbonate, and titanium which may be in the form of metal, oxide, salt, ilmenite, or ferro-titanium. Deoxidation may be completed by a small addition of aluminium.  If aluminium is required in the product, the steel is first prepared free from aluminium, and the required amount of aluminium is added after refining.  Iron oxide may be used in the form obtained by heating thin sheet steel scrap from coach building or tin-plate manufactures to 1,000-1,200 DEG C. for 20 minutes to 2 hours in an oxidizing atmosphere, the product of this treatment containing 90-95 per cent. of Fe3O4.
