Title: Apparatus for segregating articles according to their weight
IPC: B07C5/30
Filed: 1960-09-09
Abstract: 952,082. Weighing apparatus. G. F. PEMBROKE, and MOLINS MACHINE CO. Ltd. Sept. 6, 1961 [Sept. 9, 1960], No. 31154/60. Heading G1W. Apparatus for segregating articles according to their weight by separating them into groups, each comprising articles of substantially the same weight, e.g. cigarettes, comprises a weigher having an article carrier and counters which are selectively operated according to the deflection of the carrier caused by an article therein, a distributer arranged to occupy different positions to divert articles to different destinations according to their weight and means associated with the weigher arranged to control the distributer positions according to the deflection of the article carrier. A cigarette is fed from a hopper 2 by a fluted drum 3 to the scale pan 4 of a weighbeam 5, Fig. 1. An arm 6 extends from the weighbeam and carrier, as well as a scale pointer, an extension 36, Fig. 6. When a cigarette of correct weight is in the scale pan the weighbeam remains horizontal and the arm vertical, the extension 36 then occupying a midposition opposite a frame 38, Fig. 5. The distributer 10 is reciprocable by the combined action of a cam 45 and spring 44, Fig. 3. If the weight of a cigarette is correct the distributer remains in the position shown in Fig. 1 and the cigarette, discharged from the scale pan 4 and directed by a guide 8 and movable flap 9, rolls down the sloping top 10A of the distributer on to a moving band 11. If a cigarette is over or under weight the weighbeam tilts and the extension 36 moves to the right or left across the frame 38, which is caused to turn about a pivot 39, anti-clockwise as seen in Fig. 6, at every weighing operation. The frame 38 carries wedges 38A and as it moves towards the extension 36 the latter takes up a position between the two nearest wedges, the positions of which are governed by the weight of the cigarette. The extension 36 will then press against the end of a selected one of levers 30-34 which operate counters as disclosed in Specification 425,721. When the selected lever is thus moved a tail piece 43 extending downwards from it strikes an arm 42 of one of four microswitches and the appropriate one of four solenoids 53, Fig. 3, is thereby energized, moving a stop 58 to form a projection in a position corresponding to the weight of the cigarette. The spring 44, as permitted by the beam 45, moves the distributer horizontally, rods 143 on which it is mounted sliding in bearings 48, until it is halted by the projected stop 58, when the cigarettes will drop through an opening 12 in the distributer into one of four channels 13-16 which lead to boxes 17-20. The stop obstructs the distributer movement by engaging a lug 43B projecting from a rod 143 and the cam 45 then rotates out of contact with its rollers 46.

Title: Helicopter torque control device
IPC: B64C27/82
Filed: 1960-09-12
Abstract: 901,505. Helicopters. HILLER AIRCRAFT CORPORATION. Sept. 12, 1960 [Sept. 14, 1959], No. 31290/60. Class 4. A rotary wing aircraft comprises a lift rotor 4, a tail rotor 5, a gas turbine engine 8, having a free turbine chamber 14a, for driving the rotors, and means connected between chamber 14a and tail rotor 5 for automatically increasing or decreasing the pitch of rotor 5 in accordance with an increase or decrease in the pressure of the gas in chamber 14a whereby the torque compensating thrust of rotor 5 automatically increases or decreases upon increased or decreased power being supplied to lift rotor 4 by engine 8. The gases in chamber 14a are in communication via conduit 44 with the cylinder 43 above piston 42 which is biased upwardly by spring 46. Decrease or increase of the gas pressure will cause piston rod 41 to move upwards or downwards, thus pivoting link 37 about pivot 38, turning bell crank 48 and thereby altering the collective pitch of the tail rotor. The tail rotor pitch may also be altered by the pilot operated pedal 30, since movement of link 36 will pivot link 37 about pivot 40 thereby turning bell crank 48.

Title: Improvements in electric control circuit
IPC: G05B11/01
Filed: 1950-12-27
Abstract: 678,781. Automatic temperature control systems. WHEELCO INSTRUMENTS CO. Dec. 27, 1950 [July 8, 1950], No. 31364/50. Class 38 (iv). In an automatic temperature control system wherein a thermocouple 14 controls, through a, pyrometer controller 18 and relay 19, a switch 13 for energizing the heater 11 of a furnace 10 so as to maintain the temperature of the furnace at a predetermined value, external circuits comprising resistors 28 and condensers 29 are provided to obviate hunting of the system. A relay 26 operated by the switch 13 selects either one of the external circuits so as to develop a voltage across either one of resistances 16, 17 in series with the thermocouple 14, the voltage being derived from a transformer 21, rectifier 22, variable resistance 23 and relay 26 contacts 25, or 27. The arrangement is such that voltage across resistance 16 aids the thermocouple 14 voltage and that across resistance 17 opposes it. Thus, the heater 11 becomes energized at a temperature slightly below the predetermined temperature and becomes de-energized at a temperature slightly above the predetermined temperature. By suitably selecting the value of the resistors and condensers in the external circuits the voltage across the resistances 16 and 17 may be made grow and decay at a suitable rate.

Title: Liquid treating apparatus
IPC: G05D11/00
Filed: 1949-12-07
Abstract: 664,240. Mixing appliances. RUSH, H. A. Dec. 7, 1949 [Nov. 12, 1949], No. 31451/49. Class 86 [Also in Group XXIX] In a liquid treating apparatus wherein a treating liquid is delivered in a small quantity for mixing with the liquid to be treated, and proportional to the rate of discharge thereof, a flexible wall is displaced in response to the rate of flow of the liquid to be treated, the movement of the wall being transmitted to a second flexible wall spaced therefrom which in turn operates a valve to admit treating liquid into a chamber defined by the second wall, discharge means being provided from said chamber through which treating liquid flows for mixing with the liquid to be treated. As described an outlet spout 4, Fig. 2, is swingable about a bush 7 screwed to an adaptor 6 through which water under pressure is supplied from a manifold, (not shown), the water passing to the outlet passage 4a of the spout by way of a cavity 10 and passage way 15 in the hub 5 of the spout. Within predetermined limits of swinging movement of the spout 4 the cavity 10 communicates with an expansible chamber 28 through a passage 46, the passage 46 being blocked by a stationary member 47 as shown in Fig. 4 when the spout is swung to a position outside said predetermined limits. The chamber 28 is vented by a restriction 35 leading into the spout outlet passage 4a. The pressure of the water entering the chamber 28 causes movement of a flexible wall 33 which in turn displaces a flexible wall 32 spaced therefrom and forming a chamber 30, a valve closure member 41 carried by the flexible wall 32 being thus caused to open, allowing liquid treating agent to flow from a container 22 into the chamber 30 and thence into an outlet passage 54 leading to a discharge opening 19 in the spout. The stem 37 which carries the valve closure 41 has an axially extending groove 40a progressively increasing in depth from the ring 41 so that the flow through the valve is proportional to the amount of its displacement. Should the diaphragm 32 fail, the chemical passes into the space between the two diaphragms 32 and 33 and out of vents 34, the diaphragm 33 preventing leakage of chemical into the water supply system. Specification 604,479 is referred to.

Abstract: 1,186,080. Grinding. LANDIS TOOL CO. 10 July, 1967 [8 July, 1966], No. 31602/67. Heading B3D. A machine for grinding a workpiece comprises a work support 20 for rotatably supporting a workpiece, such as a poppet valve, for engagement with a grinding wheel 17 rotatable about a horizontal axis at a point other than the point of intersection between the surface of the grinding wheel and a horizontal plane through the axis of the wheel, the axis of rotation of the workpiece being at an angle to that of the grinding wheel, means for maintaining a substantially constant relation between the grinding wheel face and the workpiece, including a pivotally mounted support for the grinding wheel, and means operable as the grinding wheel becomes smaller for shifting the pivotally mounted support to compensate for change in diameter of the grinding wheel. As described, the machine is arranged to grind two poppet valves simultaneously, the valves being held in parallel, vertically spaced work-holders 23 which are driven from a motor M and carried by a base 21 adjustable in a direction parallel to the axes of the valves on a bed 11. The grinding wheel 17 is driven from a motor 18 and carried by a slide 15 adjustable on a bed 14 mounted on a base 13 which, in turn, is adjustable about a pivot P by an adjusting mechanism in a housing 30. The housing is secured to the base 13 and contains an actuating bar movable longitudinally upon rotation of a nut 36, the rotation being effected by a worm 48 which engages a wheel 47 formed on the nut and is rotated in one or other direction by selective operation of one or other of a pair of pawls engaging a ratchet wheel on the shaft 49 of the worm. The pawls are actuated by fluid pressure means controlled by a relayoperated electrical circuit. As the grinding wheel wears or after a truing operation, the actuating mechanism is operated to adjust the grinding wheel about the pivot P so that, despite the smaller size of the grinding wheel, the valves are ground at the predetermined angle.
