Title: Gate valves
IPC: F16K3/312
Filed: 1955-04-29
Abstract: 807,524. Valves. HAMER, L. S. April 29, 1955, No. 12378/55. Class 135. In a tapered gate valve comprising a tubular body having a flow passage therethrough formed intermediate its ends with a transverse chamber having oppositely facing spaced apart seats, the seats are co-operable with either a blanked or an apertured wedge-shaped valve element supported on a carriage movable transversely of the flow passage so that one or other of the elements is always visible, the carriage on being raised permitting rotation of the valve elements so that either element may engage the seats on the subsequent lowering of the carriage. As shown, blank and apertured wedge-shaped valve elements 25, 26, Fig. 2, are carried on a horizontal pin 33 supported by arms 41 of a movable carriage D. The carriage D which is guided by rods 50 is provided with a screw-threaded stem 70 which co-operates with a nut 78 held against axial movement and rotatable by a hand wheel to raise and lower the carriage. Instead of the axes of the valve elements 25, 26 being in alignment with the axis of the pin they may be angularly disposed thereto as shown by valve elements 125, 126, Fig. 6, to reduce the length of the stem 70 and of the guide rods 50. The seats may be formed on separate rings 322, Fig. 8, welded to the valve body. In this embodiment a support member 360 having slotted portions 362 in which arms 352 carrying the valve elements 335, 336 are guided, replaces the guide rods 50 and a screw-threaded spindle 370 rotates to raise and lower the carriage D<111>.

Title: Improvements in or relating to washing machines
IPC: D06F13/00
Filed: 1944-06-30
Abstract: 625,410. Washing-machines. WATSON, F. (Aktiebolaget Elektrolux). June 30, 1944, No. 12474. [Class 138 (ii)] A washing-machine has an oscillating agitator which is curved in section so as to promote uni-directional circulation of the clothes and liquid past it, and the axis of the agitator is so located in the container that the curved path swept out is inclined to the direction of circulation during part of its stroke. This is distinct from the arrangement of the agitator with its axis along the vertical centre line of the container, where the path traced by the agitator coincides with the circulation. In Fig. 1 the container 10 is cylindrical and has two agitator blades 18, 19 on a common horizontal axis 16 disposed diametrally of the container and oscillated by an external power unit 14. In the mid-position of the shaft 16, the two blades extend towards the base of the container and at an angle to the vertical ; they are curved in a plane normal to the shaft and also in a direction along the shaft, the two concave sides facing each other. The effective part of each blade extends over one half only, of the shaft so that their oscillation promotes a general circulation around the vertical axis of the container, the clothes in front of the blade being carried downwardly and upwardly across the general direction of circulation at the beginning and end of the stroke. A disengageable coupling between the shaft 16 and driving unit 14 enables the agitator assembly to be swung upwardly about a swivel bearing at the opposite end of the shaft to allow free access to the container. In the case of large rectangular containers, Fig. 10, two agitators 15 may be mounted on parallel axes 16 on the base of the container and facing in the same direction to promote a circulation as indicated. Alternatively (Fig. 11, not shown), the axes of the agitators may be vertically disposed adjacent two opposite walls of the container.

Abstract: 1,105,460. Controlling aircraft. GENERAL ELECTRIC CO. 25 March, 1965 [26 March, 1964], No. 12728/65. Heading B7G. In a prior art self-adaptive control system for an aircraft pitch control channel demanded pitch rate #c is applied to a subtraction circuit 2<SP>1</SP> together with a feedback signal #f derived by a rate gyro 12, and an actuator 20 operates a control surface 11<SP>1</SP> of an aircraft 11 so that pitch rate # follows demanded pitch rate signal #c. The output from 2<SP>1</SP> is integrated at 13 and the resultant signal is added to further signals from a multiplifier 14 and canceller 15 arranged in parallel and fed to adaptive section 3<SP>1</SP>. This consists of a sensor 17 which measures the time interval between zero crossings of a time varying signal, a memory 18 and a variable multiplier 19. According to a first embodiment of the invention, wherein Fig. 2 shows a preferred form of adaptive section 3<SP>1</SP>, an input from canceller 15 is passed to a band-pass filter 26 which passes signals in the neighbourhood of the desired constant damped natural frequency of the system, such signals being sensed by an integrator 30 in the form of a capacitor 41 and ratio multiplying resistors 42, 43 to determine the damping of the system. Successive half-cycles are gated at 46, 47 to respective resistors 42, 43 under the control of a sequence generator 45 which is triggered by a zero-crossing detector 32. The read-out from integrator 30 is gated by a gate 48 and transmitted to a memory 18 which adds a damping signalincrement to adjust the variable multiplier 19. A multivibrator in sequence generator 45 operates a reset switch 49 which discharges capacitor 41.
