Title: Improvements in or relating to windscreen cleaning systems
Inventor: OISHEI JOHN ROFFO
IPC: B60S1/48
Filed: 1959-03-17
Abstract: 920,711. Reciprocating pumps. TRICO PRODUCTS CORPORATION. March 17, 1959, No: 9243/59. Class 102(1). [Also in Group XXIII] A suction operated windscreen washer pump is controlled by an electrically actuated valve 12, Fig. 3, which is mounted on the top of a washing liquid reservoir 13 within which is a pump chamber 37 containing a hollow plunger 38. The valve 12 normally connects the upper part 39 of the chamber 37 to atmosphere, but when actuated connects the part 39 to a suction source through a hose 14, so that the plunger 38 rises against the resistance of a spring 45 and draws liquid into the lower portion 40 of the chamber 37 via a hose 48 and a flap valve 71. The liquid pressure differential closes a flap valve 72 at the pump outlet. When the plunger 38 reaches the top of its stroke a pin 44 thereon raises the valve element 30, Fig. 2, of the valve 12 so that a valve member 31 closes the communication between the upper part of the chamber 37 and the suction passage 24. At the same time a further valve element 32 carried by the member 31 is raised to admit atmospheric air to the upper part of the chamber 37 via apertures .25, the clearance between the element 32 and the valve casing, and perforations 36 in the member 31. The plunger 38, urged by the spring 45, is then moved downwardly to force the washing liquid previously drawn into the chamber 37 out through a hose 51, the flap 72 being depressed to permit the flow. To prevent the valve member 30 from snapping downwardly after the pin 44 has moved downwards, the member 30 is held positively for a short interval by a spring 47.

Title: Improved electronic tube oscillator circuit particularly for acoustic devices
IPC: G10H5/02
Filed: 1952-04-10
Abstract: 727,040. Electrophonic musical instruments. MAGER, S. April 10, 1952, No. 9250/52. Class 88 (2). [Also in Group XL (c)] The upper manual 113 controls the frequency of a valve oscillator, Fig. 1 (not shown) (see Group XL (c)), feeding a power valve connected to a loud-speaker. Operation of a key varies the tuning of the oscillator circuit and removes a paralysing bias from the output valve, the initial bias being such that key-clicks are reduced. The lower manual 112 controls a reed instrument operating from an air-chest, the volume of sound from the two instruments being controlled by pedals 119, 121. Operation of a switch enables the valve oscillator to act as the first stage of a wireless receiver. An airoperated turbine may cause a propeller 105 to be rotated in front of the loud-speaker 45 to give a vibrating character to the sound produced. Cam-operated contacts 107 allow the simulation of a plucked string instrument, and capacitors 102 may be connected across the output of the amplifier to vary tone. Air may also be applied through a regulating valve to a turbine, Fig. 4 (not shown), to rotate a multipolar element which affects the magnetic feed-back circuit of the oscillator, and hence varies the frequency of the oscillator.

Title: Improvements in or relating to packaging apparatus
IPC: B65B59/02
Filed: 1943-06-09
Abstract: 566,124. Packing-machines, ROSE, A. G., KAY, J. A., and ROSE BROS. (GAINSBOROUGH), Ltd. June 9, 1943, No. 9251. [Class 94 (i)] Relates to a packaging- apparatus, such as is described in Specification 541,421, which is adjustable for the accommodation of fibreboard containers of different width and/or height by means of an automatic controlling member for adjusting guide rails bearing upon the sides of the containers as they pass to a closing and sealing station. According to the present invention, the movements of the controlling members 22, 23, Fig. 2, such as described in the above Specification, are operated by feeler members 13, 14, Figs. 1 and 2, arranged to engage the articles and to be moved thereby outwardly against the action of spring &c. urging means. The containers 11 are advanced by rollers 16 and a series of containers are checked by a fixed stop 18 on a side of the machine against which the containers move by gravity owing to all inclination of the rollers 16. Adjacent the stop 18 is a stop 19 which controls the movement of the front container into the measuring station 12 where it is acted upon by the feelers 13, 14, and another stop 21 is actuated to release the container when the control operation is finished. The stops 19, 21 are operated by solenoids 24, 26 controlled by micro-switches 44, 45, 46, 47, 48 which are normally closed and maintain the stops in inoperative position when the controlling members 22, 23 are in neutral. As the feelers are operated, the controlling members operate the micro-switches to cause de-energization of the solenoids and springs bring the stops into active position. The solenoid 24 also actuates a push bar 41 by means of links 42, 43 to push the container away from the stop 18. The feeler 13 is carried by a shaft 52 mounted in arms 53 pivoted in frames 56, and motion is transmitted from the shaft 52 to the controlling member 22 by means of a rack 62 depending from an arm 57 on the shaft and gear mechanism including spiral gears 69, 71. The feeler 14 is carried by a shaft 74 having an arm 76 connected by a link 78 to an arm 77 on the member 23. The members 22, 23 in addition to controlling the solenoid switches control also switches 86-89 for controlling the motors which effect the adjustments of the packing-machine, the switches 86-89 being of the normally open type as indicated on the diagram, Fig. 4. To prevent premature feed of a succeeding container of a size which differs from the preceding one before this has passed through the measuring station 12, a safety switch 28 is provided and is operated as in the machine of the prior Specification. When containers of the same size are passing the action of the safety switch 28 is over-ridden by equalizing switches 29, 31. From the station 12 the containers are fed by a belt 79 supported on rollers 81 and entry to the packing station is controlled by a stop 91 actuated by levers 93 under control of a cam 94.

[Also in Croup XL (c)] In a waveguide switch, or amplitude modulator, modulation or a switching pulse is applied to a coil surrounding the waveguide to vary the longitudinal magnetic field in a ferrite bar extending coaxially along the waveguide and the ferrite bar is in two parts separated by a resistive material lying in a plane parallel to the wider walls of the rectangular waveguide, a TE 10  mode being employed. Two opposite or even three walls of the guide may be cut away at the modulation section for thick ferrite bars, or two remaining opposite walls may be reduced in width. The bar is tapered at each end and its cross-section must be small enough to prevent Faraday rotation and a negative slope portion of the attentuation/magnetization curve in the linear portion preceding saturation. The resistive foil may be of the same order of thickness as the depth of penetration of its conductivity by the microwave field to prevent output interference effects. The ferrite may be of Ni-Cu-Mn or Mn-Al or (for X-band) Mg-Mn types. The foil may be graphite paper or mica with vapour-deposited tantalum. The damping ranges between 2 db and 40 db at magnetic saturation. The modulation may be wide-band up to high frequencies.

A radial sliding vane rotary compressor, comprises a stator 10, Figs. 4 and 5, a cylinder 11 sealingly rotatable therein about an axis O and a rotor 22 having a plurality of equally spaced radially sliding vanes P, P 1  . . . P 6  rotatable about an axis O<SP>1</SP> parallel to but offset from the axis O so that the rotor is constantly tangential to the cylinder along a contact generatrix O 0 . The vane P is pivoted to the cylinder 11 about an axis M parallel to the axes O, O<SP>1</SP> and engages at its ends in diametrical grooves in circular discs 23, 24 rotatable in cavities 25, 26 in cylinder end plates 17, 18. On rotation of the cylinder 11 by means of a shaft 19 the rotor 22 rotates about the eccentric portion of a stud shaft 20 secured to the stator. The cylinder 11 is formed with fluid-transfer slots A, A 1  . . . A 6 , communicating respectively with pump chambers C, C 1  . . . C 6  and successively with compressor inlet and discharge ports 28, 30 on rotation of the cylinder and rotor. To maintain a substantially constant compression ratio, constant delivery pressure and a steady amount of work done throughout each revolution, the angular distribution of the slots A . . . A 6  with respect to the angular distribution of the vanes P . . . P 6  is in accordance with the mathematical formula:- in which starting with a radial plane including the axes O, O<SP>1</SP> and the generatrix O 0  as datum αK = the angle of a generic vane PK; #K = the angle of the associated slot; #K = azimuth angle of vane k; v = the angle between a vane. From this formula for the first 180 degrees rotation of a vane from the datum plane a vane lags with respect to its cylinder slot, varying continuously from zero through positive maximum back to zero and for the subsequent 180 degrees rotation leads with respect to its cylinder slot from zero through negative maximum back to zero. Alternatively the slots A . . . A 6  may be equally spaced around the cylinder and the vanes P . . . P 6  spaced in accordance with the formula.
