Abstract: 1,254,933. Laminate. MILLIPORE CORP. 3 Feb., 1969 [25 March, 1968], No. 5649/69. Heading B5N. [Also in Divisions B1 and C7] A laminated sheet suitable for the evaluation of diffusive reactions by electrophoretic or chromotographic techniques comprises a flexible self supporting non-porous plastics base sheet 1 e.g. of polyester, a microporous membrane 2 of plastics material e.g. cellulose acetate, preferably of pore size 0À5-1À5 mÁ and a thin flexible non- porous sheet 4 e.g. of polyester, said sheet being disposed relative to the membrane 2 to expose a multitude of adjacent pores. The layer 4 may be shorter than the membrane thereby leaving the end portions exposed for the attachment of electrodes or may be provided with openings 6, 7 through which the membrane is exposed. The layers may be bonded by thermoplastic adhesive films 3, 5 and the flexible layer 4 may be peelable from the membrane. The laminate may be made by superposing the adhesive coated layers and subjecting them to heat and pressure.

Rotary batch-mixers.-In a machine for mixing concrete &c., a set of blades D extend substantially diagonally from a point near the charging end B of the drum A but spaced therefrom so as to leave an interval between them and the head at their ends to a point in the interior of the drum, the blades being adapted to raise the material as it rotates with the drum and project it against the head C and closure door F of the drum. The door F has a concave inner face F<1> to deflect the materials, and an outwardly flaring edge F<2> to engage the flange C<2> surrounding the discharge opening C<1>. The blades E at the discharge end C of the drum are truncated half-cones of irregular form with one edge E<1> turned in, and extend on approximately radial lines toward the centre. The door F is keyed to the end of a shaft J mounted in bearings L so as to rotate with the drum A, and is opened by means of a lever K having a slot K<3> at its fulcrum bolt K<4> so that the door has a compound longitudinal and oscillatory movement. Reference has been directed by the Comptroller to Specification 105,235.

Title: Improvements in pressure liquid actuated reciprocating motors
IPC: B60S1/12
Filed: 1965-02-11
Abstract: 1,038,645. Hydraulic reciprocating motors. ROBERT BOSCH G.m.b.H. Feb. 11, 1965 [Feb. 22, 1964], No. 5909/65. Heading F1A. An hydraulic motor, e.g. for a windscreen wiper, comprises pistons 42, 43 acting to oscillate a shaft 78 through a pin 84 and lever 82, smaller diameter piston 42 being constantly under pressure during operation and larger diameter piston 43 being alternately connected to pressure and exhaust by valves C, D, controlled by a snap-action lever, an adjustable time delay being provided at the end of the leftward stroke by a piston 94 resiliently coupled to lever 82 and slidable in a cylinder 95 from which liquid is exhausted via an adjustable throttle. To start the motor, rod 29 is pulled to tilt lever 26 and depress rod 34 having a wedge 37 which acts on a sliding member 38 to depress a pin 19 and open inlet valve 16. Pressure liquid from a throttled inlet A, which is set to provide a predetermined operating speed, then passes via valve 16, passage 23 and working chamber 50 to inlet and exhaust valves C. D. In the position shown, valve C is open and valve D closed, so that liquid enters working chamber 51 via passage 74 and moves the pistons to the left. Levers 82 and 81, Fig. 3 (not shown) are fixed to output shaft 78. A spring 87 has an end 88 engaging a stop 89 on lever 81 and an end 90 slidable on surface 91 on lever 81, Fig. 2 (not shown), and engageable with valve-operating lever 99 and time delay piston head 93. When the pistons move to the left, lever assembly 80 swings anticlockwise, spring end 90 following the throtted movement of piston 94. After a time delay depending on the throttle setting, spring end 90 engages lever 99 and swings it anticlockwise until a stop 103 on the lever engages a pin 104 on the valve actuating assembly which is then swung over centre due to spring 114. Pin 104 then engages a stop 112 on ram sleeve 106 to rotate the sleeve anticlockwise from the position in Fig. 1, so that valve C is closed and valve D opened by sleeve 106 acting through push rods 68, 69. The piston assembly then moves to the right, chamber 51 exhausting via valve D and housing cavity 44 to outlet 3. This moves lever 80 clockwise with lever 99, by engagement of a stop 92, thereby reversing the valve gear. Piston 94 is returned by spring 96 and its cylinder refilled from cavity 44 by a passage. For stopping the motor, rod 29 is pushed so that rod 34 releases member 38 which cannot move upwardly to close valve 16 until piston 94 is in its innermost position, so the motor continues to operate until this occurs, thereby providing automatic parking of the wipers.

Title: Improvements in or relating to electric circuit arrangements for operating cathode ray tubes

IPC: H04N3/26
Filed: 1954-03-02
Abstract: 781,577. Electron beam apparatus. GENERAL ELECTRIC CO., Ltd. March 1, 1955 [March 2, 1954], No. 6092/54. Class 39(1). [Also in Group XL(c)] A valve for producing a correction voltage for neutralizing focus variations in the scanning beam of a cathode-ray tube (see Group XL(c)) comprises an electron gun 13, 14 producing a beam 2 mm. in diameter which is deflected synchronously with the beam of the cathode-ray tube by means of external line and frame scanning coils, a cylindrical electrode 15 with an inward flange 19 defining an axial aperture 3 mm. in diameter and a circular collector electrode 16 such that when the beam is in the central region of its scan electrode 16 collects all the electrons from gun 13, 14 but when the angle of beam deflection exceeds a certain value a progressively increasing proportion of the beam is intercepted by the flange 19 thereby reducing the number of electrons reaching electrode 16. The required correction voltage is derived from a potentiometer connected to electrode 16, Fig. 1 (not shown) ; alternatively push-pull correction voltages may be derived from electrodes 15 and 16. The potential of electrodes 14, 15 and 16 relative to cathode 13 may be -30v, + 500v and + 1,000v respectively. Control of the beam diameter and thereby of the output waveform is effected by adjusting the relative potentials of electrodes 14 and 15. Constructional details. The electron gun comprises a hollow cylindrical cathode 13 with an emissive coating 33 on its closed end, the cathode having an internal heater 45 and being supported coaxially within a cylindrical member 31 having a closed end 32 provided with a central hole which constitutes the electrode 14. Electrodes 14 and 15 are supported by three insulating rods 40 passing through holes in two substantially triangular flanges 34 extending radially outwards from each electrode, one flange of each electrode being attached to the rods by clamping clips (not shown), and the spacing between electrodes 14 and 15 being determined by steatite spacing washers 36. The electrode 16 is welded to a rigid lead-in wire 47. The electrode assembly is mounted in a cylindrical glass envelope 37 by support wires 39 sealed into the plinth 44 and attached by metal clamping clips 38 to the lower ends of insulating rods 40, the upper end of the electrode assembly being held by three metal spring fingers 43 welded symmetrically around the upper triangular flange 35.
