Title: Improvements in cement mixers
Inventor: DAVIES LEONARD TRUMAN
IPC: B01F5/10
Filed: 1950-09-11
Abstract: 694,117. Mixing appliances. COLCRETE, Ltd. Dec. 10, 1951 [Sept. 11, 1950], No. 22279/50. Class 86 A cement mixer for producing "colloidal" grout or concrete comprises a mixing and pumping unit connected in closed circuit with a hopper so that the mixing and pumping unit can draw water and cement from the bottom of the hopper and discharge it tangentially into the upper region of the hopper causing the mixture to flow down the side of the hopper in a vortical manner, the hopper having a deflector on the bottom extending circumferentially and inwardly towards the bottom outlet so as to direct the mixture in such a way as to prevent the mixing and pumping unit from drawing air. As described, the apparatus comprises two interconnected hoppers 1, 2 each having a mixing and pumping unit 8, 9, the hopper 1 serving for the production of a cement and water mixture which is delivered into. the hopper 2 for the addition of sand. Be- . tween the hoppers 1, 2 and mixing units 8, 9, are provided traps 5, 6, the trap 5 having an inlet pipe 7 through which a measured quantity of water is introduced prior to the addition of cement. The mixing unit' 8 comprises a rotatable disc 10 mounted with a very small side or axial clearance within an enclosed casing 11 so that the particles of cement will be separated by rapid relative motion between the surfaces on the disc 10 and casing 11. With the disc 10 in motion the cement is introduced through the upper end of the hopper 1, is guided down the walls of the hopper by a cone 14 and is taken up with the water by the mixing unit 8 and pumped around in closed circuit passing back tangentially into the hopper through a pipe 24,. a spiral deflector 29 serving to direct the mixture into the trap 5 so that air will not be drawn into the mixture. A pipe 25 connects the mixing unit 8 with the hopper 2 and the pipe sections 22, 23 are flexible so that -one or the other may be closed by flexure by a device 27. When the cement and water are sufficiently admixed the pipe 22 is closed and the pipe 23 opened so that the mixture is delivered into the hopper 2 wherein a similar operation is performed on the cementwater mix and sand introduced into the upper end of the hopper 2. The mixing unit 9 has a bladed impeller 12 whereby to beat the ingredients into a state of relatively fine admixture. Flexible pipe sections controlled by a device 31 are provided leading to the return pipe 28a and discharge pipe 28. The apparatus may be mounted on a portable chassis, Figs. 2 and 3 (not shown).

Abstract: 704,028. Protractors. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 24, 1952 [Sept. 24, 1951], No. 22302/51. Class 97(3) [Also in Group XXIII] A gauge for setting the height of a tooth rest of a machine for grinding milling cutters comprises a semi-circular protractor 1 mounted by means of an arcuate guide 1a in a stock 2 on the machine so that its centre of rotation about which it rotates is coincident with the axis' of a mandrel 3 on which the milling cutter 14 is mounted. A straight edge 4 is formed by the end face of the shorter limb 5 of an L-shaped member the other limb 6 of which is mounted in a linear slide 7 in such a position that an extension of the straight edge as indicated by line 9 would pass through the centre of generation of the protractor. The radial distance of the trip 8 of the straight edge from the axis is adjusted to the required diameter of the cutter with the aid of graduations 10 on the limb 6 and is locked by means of knurled nut 7a. The protractor is then adjusted angularly with the aid of graduations 11 and locked by means of a knurled nut 7b so that the angle subtended by the straight edge relative to an axis usually horizontal, which is normal to the face of the grinding wheel 12, and passes through the centre of generation of the protractor, is equal to the desired clearance angle. With the straight edge so adjusted the tooth rest 13 is brought up into contact with it, and the L-shaped member moved out of the way.

Abstract: 1,273,236. Machine tool details - gauging. INFRARED INDUSTRIES Inc. 1 May, 1969 [14 June, 1968], No. 22302/69. Heading B3B. [Also in Division G2] An optical device allows scale divisions to be divided and sub-divided. In the milling machine embodiment shown, an objective 20 and mirror system 38 magnify and project an image of the scale 15 into the part of a screen 30 at which a series of slots 32 are formed, and by rotating a cam 40 in contact with the screen 30 it is possible to align one of the scale indicia 16 with one of the slots 32. The scale readings are thus divided ten times to give two places of decimals, e.g. 23À45 as shown. For further division, the movement of the screen is measured; for this purpose the cam 40 is provided with a scale 41 and a part of this is projected into a reading area 35 of the screen. An ordered sequential left to right read-out is thereby provided, the embodiment providing measurement to four places of decimals; a full reading of 23À4567<SP>11</SP> is illustrated.

The armature 1 of a direct-current motor, which may drive a planing machine, is supplied from alternating-current mains 7, 8, through a grid-controlled mercury arc rectifier 9. A relay 16 is supplied from a power transformer 14 through the excitation anodes 12, 13, of the rectifier so that, in the event of failure of the supply-voltage or a fault in the main rectifier, the relay is de-energized to close contact 5.

Title: Improvements in variable-rate pulse counting circuits
IPC: G01T1/18
Filed: 1955-08-15
Abstract: 790,143. Automatic voltage control systems; rectifying. BENDIX AVIATION CORPORATION. Aug. 15, 1955 [Aug. 20, 1954], No. 23464/55. Classes 38 (2) and 38 (4). The E.H.T. supply voltage to a Geiger- Muller counter tube is maintained substantially constant, with fluctuations in current demand due to variations in the pulse discharge rate of the counter, by compensating the supply in accordance with said discharge rate. Thus, the saw-tooth pulsed output of a multi-vibrator comprising tubes 10, 16 is applied to a choke 13, whereby the rapid decay of the saw-tooth pulses results in the generation of large amplitude positive pulses across the choke. These pulses are applied over a condenser 26 and a rectifier tube 28 to an integrating network 29, 30, whereby the substantially constant voltage to which the condenser 30 is charged is applied to the counter tube 32. This voltage is determined by the multivibrator frequency which may be set by a resistor 15 in accordance with the characteristics of the tube. A signal representative of the counter discharge rate is derived from an integrating network 38 for application to the grids of tubes 16, 28, whereby the amplitude of the multivibrator oscillations is varied to cause corresponding corrective changes in the voltage to which condenser 30 is charged.
