Title: Improvements in or relating to thermostatically-controlled valves suitable for incorporation in liquid flow systems
Inventor: STEADMAN CLIFFORD STUART
IPC: G05D23/12
Filed: 1951-12-13
Abstract: 722,913. Cooling systems for I.C. engines; temperature - responsive actuating- elements. SMITH & SONS (ENGLAND), Ltd., S. Dec. 11, 1952. [Dec. 13, 1951] No. 29210/51. Classes 64 (2) and 64 (3). [Also in Group XXIX] A thermally-controlled valve 4 in a liquid flow system such as an I.C. engine cooling system and which closes against a seat 5 below a certain temperature (the operating temperature), has a passage 6 through it controlled by an auxiliary thermally-operated valve 7 so that the passage is open below a further temperature itself below the operating temperature and is closed above the further temperature. The auxiliary valve 7 is a bimetal annulus secured by rivets 8 at one side thereof. Liquid enters a port 9 in a housing 1 containing an air-filled bellows 2 which controls the main valve 4. When filling the system with cold liquid, the valve 7 permits the escape of air across the closed valve 4 but is closed at normal temperatures of the system.

Title: Device for stabilising apparatus for aerial navigation
IPC: B64C1/00
Filed: 1935-10-23
Abstract: 463,983. Flying - machines. OEHMICHEN, E. E. Oct. 23, 1935, No. 29277. Convention date, Oct. 31, 1934. [Class 4] In an aircraft of the helicopter type provided with a capacity partly or completely closed and containing atmospheric air, the centre of volume of the aircraft being entirely distinct from the centre of gravity and located above it, surfaces offering aerodynamic resistance to horizontal translation are disposed below the centre of gravity in such a. position that the resistance of the air to both lateral and fore-and-aft movements is applied at a point which is located at or as near as possible to the general centre of gravity of the aircraft. The Specification comprises a detailed analysis of the stability of a helicopter combined with an air-filled envelope. An envelope is employed either provided with a keel Q, Fig. 11, or of irregular shape, Fig. 7, such that the centre of pressure R in lateral horizontal movement along Y-Y<1> is below the centre of volume C. In order to lower the centre of pressure in longitudinal movement along axis x-x elements such as engine and passenger nacelles are placed as low as possible as at r<1>, r<2>, Fig. 11. It is stated that the condition that the centre of resistance should coincide with the centre of gravity is only an essential when the apparatus is substantially stationary or moving at low velocity, since at high speeds normal tail organs provide stability, and that, therefore, movable surfaces such as panels P<1>, P<2>, Figs. 13 and 14, may be employed which can be rendered inoperative for high forward speed. Alternatively, the panels may be substituted by variable pitch screws h<1>, h<2>, Fig. 15, which when at zero pitch offer substantial resistance to forward movement and may be set at a positive pitch angle for high speed flight. The screws may be controlled by the pilot in such manner as to produce a dynamic restoring couple in the case of pitching. The main propelling screws H, Fig. 16, are inclined and exert a tractive effort t<1>, the auxiliary screws h developing an opposing thrust t. With this arrangement the thrust of the principal screws is reduced and that of the auxiliary screws increased on movement in the direction Cx and the converse takes place on movement in the direction Cx<1> so that a resistance to movement along line x1-x<1>1 is always set up.

Abstract: 1515516 Cutting apparatus ALBRECHT BAUMER KG SPEZIALMASCHINENFABRIK 11 July 1975 [16 July 1974] 29299/75 Heading B4B A twin-edged cleaving machine for cutting sheets from a block 9 of foam plastics material comprises a twin-edged blade 10 mounted in a support 6, a table 5 for the block of plastics and movable relative to the blade support, the blade being supported against deflection by an elongated bar 15. The bar is held under tension in the support 6 by means of a clamping and tensioning device 20, Fig. 5. The tensioning device is mounted on slideways 31, 32 via roller bearings 26, 27 such that by means of a linkage mechanism 40, Fig. 4, actuated by a pneumatic ram 45, the bar can be moved transversely to expose the respective cutting edge (10a, 10b), Fig. 2 (not shown) depending upon which direction the block of plastics is moving. The linkage and actuator means can also pivot the bar by means of a member 30 rotatably mounted on the support 6; the degree of pivoting movement is adjustable by a stop 46, Fig. 4, such that the angle of attack of the cutting edge with respect to the block can be varied. At each traverse of the table, the support 6 is lowered by an amount equal to the required thickness of the sheet. In order to prevent the blade 10 from sagging away from the bar 15, the latter is formed with grooves (16) or (17), Fig. 2 (not shown) connected via apertures (18) or (19) and a suction head 51 to a source of vacuum; alternatively, the blade may be held by magnetic means. In modifications, the two cutting edges may be provided on separate blades (101, 102), Fig. 6 (not shown) and the cutting edge formed with tooth-like cut-outs (10a-10d), Fig. 3 (not shown).

Filed: 1946-10-04
Abstract: 622,128. Pulse-shaping circuits. SADIRCARPENTIER. Oct. 4, 1946, No. 29706. Convention date, April 30, 1945. [Class 40 (vi)] A circuit for deriving from two short pulses of opposite polarity a single pulse of which the leading and trailing edges correspond in time with the leading edges of the two short pulses comprises a capacitor charged through one rectifier and discharged through a second rectifier. In the Figure, the two rectifiers are connected in opposite directions to a potentiometer in series with a source 10 of short pulses and connected across a battery 6. The capacitor 4 is connected across a resistor 5 to form a circuit having a time constant which is long compared with the duration of the pulse to be reconstituted. When a positive going pulse appears at 10, rectifier 1 conducts and capacitor 4 charges up to the voltage of point 12. At the termination of the pulse, the capacitor discharges via rectifier 2 to the voltage at point 11, this charge being held by the capacitor until the appearance of a negative-going pulse at 10 when it discharges through rectifier 2 to the new level of point 11. When the pulse terminates, rectifier 1 conducts, and the circuit restores to its initial condition.

Title: Improvements in light signalling circuits more particularly for railways
IPC: B61L5/18
Filed: 1931-10-30
Abstract: 386,071. Electric signalling systems. MEYER, K., 51, Reichsstrasse, Charlottenburg, Berlin. Oct. 30, 1931, No. 30092. [Classes 40 (i) and 118 (ii).] Lamp signals are selectively lit, by opening or closing a single switch contact, from a single phase supply through a choke coil D to which are connected a first (green) lamp F through the switch S, and a second (red) lamp H and series condenser C, permanently connected to the choke coil D, which lie in parallel with the first lamp. With the switch closed the green lamp F only is lit since the red lamp H by reason of the condenser reactance only has a fractional current. With the switch open the red lamp H has full current since the condenser reactance compensates the choke coil reactance. The arrangement shown in Fig. 2 comprises home and distant clear and stop signals. The home clear signal is a two-aspect one as the switch S is a change-over switch enabling one or both lamps F<1>, F<2>, to be lit. The distant clear signal VF is energized by the home signal current through a series saturated transformer T<1> so that if a distant lamp VF burns out the home lamps F<1>, F<2> will still remain lit. The home stop signal H<1> is energized from a transformer T<2>. On failure of this lamp H<1> the transformer primary current falls whereby the primary applied voltage rises by reason of the lessened drop over the resistance W and the transformer secondary voltage likewise rising lights up the auxiliary stop, lamp H<2> connected to a tapping on the transformer secondary. The distant stop signal VH is energized in parallel with the home stop signal primary circuit. Fig. 3 shows an arrangement wherein an auxiliary lamp HN is lit on failure of the stop lamp H by the compensating effect of the reactance of the choke D<1> in a manner corresponding to the lighting of the red lamp when the green lamp circuit is opened.

Filed: 1945-11-12
Abstract: 637,505. Gyroscopic apparatus. STALKER, E. A. Nov. 12, 1945, No. 30172. Convention date, Nov. 17, 1943. [Class 97 (iii)] [Also in Group XXIV] Speed ratios varying automatically with speed and load are obtained by gyroscopic flywheels 8, which, in addition to being spun and turned end-over-end by the relative rotation of aligned driving and driven shafts 1, 2, so as to develop a resistance resulting in an eventual one-to-one drive when speed and load conditions permit, are also cyclically oscillated by a crank 4b and connecting-rods about an inclined pivotal axis on their spin-shafts so as to avoid the production of negative torque-impulses. Four fly-wheels 8 are mounted on coplanar radial shafts 14 in the inside of a shell 11, which journals about a diameter 4, 5 in a ring 3 secured to the driving-shaft 1. One journal 5 is rotatable in the shell and ring, and carries at its inner end a bevel 9, meshing pinions 10 on the flywheel spin-shafts 14, and at its other end a bevel 6, meshing a wheel 7 permanently geared at 29, 32 to the driven shaft 2, so that relative rotation between the driving and driven shafts 1, 2 spins the flywheels on their own axes. At the same time the bodily rotation of the fly-wheel carrying shell 11 with the driving-ring 3 and input shaft 1, causes the. flywheels to apply a precessional torque about the transverse axis 4, 5 to the support-shell 11 and thence to the driven shaft 2 through fast bevels 12, 13, this torque producing the automatically variable drive. Resultant negative torque-impulses produced by the fly-wheels 8 at certain positions in their cycle are avoided by hinging the fly-wheels on their spin-shafts 14 so as to be able to oscillate about single axes at right-angles to the shafts 14 and also inclined along a line L in relation to the central diameter 4, 5 of the shell 11, as by hinges 18 (dotted on Fig. 5) and by a pin-and-slot ball-mounting 20a. Bearings 15 on the fly-wheels 8 are linked at 23 to an eccentric 4b on the shell pivot 4, which is fixed in the driving-ring 3, so that, as the shell rotates about the diameter 4, 5, the flywheels are also cyclically oscillated on the inclined axes, the arrangement being such that the positive precessional drive-torque is always greater than the negative in all positions, giving a resultant forward drive. In Figs. 6 and 7, not shown, each fly-wheel is in the form of four segments separately hinged to their supports.

By this means, the signal Qo is delayed by n2 lines plus n 2 /2 dot raster periods, for example, (in the case of the second delay device) directly (see Fig. 2b; 2c) instead of requiring conversion back into a T S  signal by an extra D flip-flop 34, (Fig. 9 of parent).
