Title: Improvements in or relating to vapour power systems
IPC: F01K25/08
Filed: 1928-02-09
Abstract: 285,374. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Feb. 14, 1927, [Convention date]. Vapour engines.-In a vapour power system, a working-medium with a retrograde, upper limit Mollier curve such as toluol or other homologues of the benzols, is expanded in an engine from a point below the critical point in front of its point of reversal whereby it becomes saturated and then superheated. An electrically driven pump 1, Fig. 2, draws the power liquid from a tank 3 and delivers it to a heater 4 heated by a burner 5. The liquid working medium expands in the turbines 7, 8 through the zone of saturation into the zone of superheating, so that superheated vapour passes to the condenser 9 and the condensate returns to the tank 3. Small fluctuations of load are balanced by adjusting the feed supply 15 through the governor 16. Larger variations, by regulating the quantity of the working-medium by adjusting valve 18.

Title: Detonating cap safety devices
IPC: F42C15/192
Filed: 1972-01-31
Abstract: 1353841 Projectile fuzes RHEINMETALL GmbH 31 Jan 1972 [13 Feb 1971] 4360/72 Heading F3A [Also in Division E2]  A safety fuze for rotated or unrotated projectiles comprises a housing 1, Fig. 1, containing a rotor 3 which is arranged to be driven by a worm 26 and spring 27 into an armed position where a detonator 2 can be ignited, through an opening 22, by an electric contact or a primer. The rotor is initially locked in a safe position by a pin 23 which projects through an opening 21 in the housing and into a slot 24 in the rotor. The pin depends from a pivoted arm 16 which is itself locked against movement by the reduced portion 15, Fig. 1 and 2, of an inertia bolt 4. A ball 12 and a further inertia bolt 5 retain the bolt 4 in its operative position. The rotor is also locked in the safe position by a ball 34, Figs. 1 and 4. A punch consisting of two portions 32 biased apart by a spring 33 retains the ball 34 in its locking position. A piston 37 responsive to propellant gas pressure is provided for activating the punch. Upon firing a projectile fitted with the fuze, the bolt 5, Fig. 2, sets back and allows the ball 12 to escape, whereupon the bolt 4 sets back. The arm 16, Fig. 1, so released, then swings outwardly under the action of a spring or centrifugal force and withdraws the pin 23 from the rotor. Meanwhile the piston 37, Fig. 4, driven by the propellant gases, causes the punch to rupture a member 30, whereupon the spring 33 moves the two portions 32 apart to create a gap into which the ball 34 drops, thus freeing the rotor for rotation under the action of spring 27, Fig. 1.

Abstract: 720,721. Aerials. GRUNDIG, M. Feb. 17, 1953 [May 23,1962; Aug. 9, 1952], No. 4418/63. Class 40 (7). An aerial comprises a coil K of high permeability magnetic material and of elongated form on which is mounted at least two coils I and II located on the core at points where the product of the inductance (L) and the Q factor at the frequency of use, is approximately at its maximum value. Fig. 1 shows graphically above a diagram of the aerial the variations of L, Q, and LXQ, for variations in the positioning of the coils. The core need not be straight but may be of S, C, or angular shape and the coils are preferably subdivided into separate spaced serially connected small coils S<SP>1</SP>, S<SP>2</SP>, S<SP>3</SP> and S<SP>4</SP>, S<SP>5</SP>, S<SP>6</SP>. One of the coils may be mounted adjustably for tuning purposes and the aerial is most sensitive if the higher potential ends of the coils face inwards. An aerial, Fig. 2 (not shown), arranged according to the invention for a number of wave ranges may consist of a ferrite core wound with two silver plated copper tape coils in series brought out to the short wave-band connection terminals, a set of two sectioned coils similar to those of Fig. 1 brought out to the medium wave-band terminals, and two extra sectioned coils that may be connected in series with the medium band coils for use over the long wave-band. When the aerial is to be used for ultra-short waves the core K is made to resonate as a dipole in the range to be received and coupling to it effected by any suitable means.

Title: Improvements in apparatus for controlling the humidity and temperature of air
IPC: F24F3/153
Filed: 1934-02-12
Abstract: 428,319. Conditioning air. ANDREW, T., 17, Oliver Street, Stockport, Cheshire. Feb. 12, 1934, No. 4552. [Class 137] Apparatus for controlling the humidity and temperature of air comprises a fan a and a thermostat z controlling the action of a pump c which delivers water to a spray b through which the air passes, the water being heated by steam from a pipe d also controlled by the thermostat z. Delivery branches a<1> each have a heater g and louvres h brought into action by a hygrostat 6, 6<a> in cases of high relative humidity, one of the hygrostats 6 also causing in cases of low relative humidity, the operation of the sprayers. An air compressor i delivers into a receiver j from which a pipe k leads to a thermostat m controlling by a motor n the louvres e, e<1> which admit fresh and re-circulated air. The spraying water and steam are controlled by diaphragms r, w, but a diaphragm t connected by a pipe s with the pressure side of the pump ensures that compressed air passing through a delay action device v does not actuate diaphragm w admitting steam until the water is passing to the spray. The thermostat z controls a leak orifice in the air main 2 so that, when the temperature falls, air pressure in the main 2 builds up, diaphragm r opens a water valve p and steam valve x, so that heated water is sprayed into the air in the trunk 10. Back pressure valves 3 and 5 are provided. An increase of humidity at the hygrostat 6 effects an escape of air from the main 7, and the fall in air pressure opens the steam supply to the heater g, and partially closes the louvres h so that the air temperature rises and relative humidity falls. If the humidity falls the steam is cut off and the louvres opened, at the same time the air pressure acts via the back pressure valve 5 to cause water and then steam to be delivered to the sprayers b. The control means may be electrical or hydraulic instead of pneumatic.
