Title: Apparatus for loading packaging containers with articles of varying sizes
IPC: B65B59/00
Filed: 1980-07-23
Abstract: An article conveyor 6 of a bag loader comprises two side-by-side conveyor belts 9 and 10 having a plurality of pockets 7a ... 7e defining between separator strips 15a ... 15d (carried by conveyor belt 9 and defining the trailing side of the respective pocket) and a plurality of associated separator strips 12b ... 12e (carried by the other conveyor belt 10 and defining the leading side of each pocket). Adjustment of the width of the pocket is achieved by shifting the angular orientation of one of the conveyor belts 10 on its circulating path relative to the other conveyor belt such that, even though the two conveyor belts 9 and 10 are normally driven synchronously from the same drive source, mere shifting of the orientation of the drive pulley for one (9) of the conveyor belts on a drive shah carrying the pulley of the other conveyor belt 10 will effect the necessary change in pocket width. The articles are ejected from the pockets by means of a single reciprocating article pusher (5) moving transversely of the direction of belt circulation. <IMAGE>

Title: Barrel for detonation coating apparatus
Inventor: KLIMENKO VALERY STEPANOVICH
IPC: C23C4/12
Filed: 1981-06-23
Abstract: A barrel for apparatus for applying a coating by a high-temperature detonation coating material spraying technique. The barrel is made in the form of a tube 1 having a closed end 2 and an open outlet end 3. Inside the bore 6 of the tube 1 at its outlet end 3 is secured at least one insert 8 having a wedge- shape section. The insert 8 is of harder material than the tube 1, and may be cooled.

In the apparatus disclosed herein, a matrix of lenses 4 or, alternatively, "flats" on a lens surface or areas of intersection between crossed prisms or cylindrical lenses, define an array aperture portions, radiation received through which is directed to form respective source images superimposed upon one another on the sensor array 5. <IMAGE>
Patent GB-2087100-A (GB)
Title: Continuous strip casting
IPC: B22D11/16
Filed: 1981-08-26
Abstract: The invention relates to a method for the monitoring and control of operating parameters of a machine for the continuous casting of strips between rolls, including the torque exerted on at least one of the rolls to cause the strip to advance and/or the stress exerted by the strip on at least one of the journals and/or the temperature of the strip as it leaves the rolls and permanently measuring the deviation between the instantaneous value of one of these parameters and the mean value of this parameter over a period of time immediately beforehand. If this deviation exceeds a reference deviation, the casting speed of the machine is reduced until the deviation again becomes less than the reference deviation. The speed of the casting machine is then increased for as long as this deviation remains lower than the reference deviation.

Title: Motor control circuit for a brushless DC electric motor
Inventor: LANGLEY LAWRENCE W
IPC: H02P6/06
Filed: 1982-07-13
Abstract: The motor has plural sets of windings 45,46 and plural drive sections 27,28 each operative to commutate one of the sets of windings. The drive sections are coupled to a power source 32 by a switching circuit 30,35,36 which, in response to the speed of the motor, places the drive sections and thus the winding sets either in a series or in a parallel configuration across the terminals of the power source. As a result, the winding impedance and the back electromotive force reflected back to the power source is varied in accordance with the motor speed, thus enabling high torque at low speed and low torque at high speed. <IMAGE>

Title: Apparatus and method for avoiding bursting of conduits
Inventor: DOUGHTY COLIN DAVID
IPC: F24S10/75
Filed: 1983-03-24
Abstract: A solar energy collector, particularly one which uses water as a working fluid, has top and bottom header tubes 14, 16 provided with flanges 22, 24 of tapering width along the lengths of the tubes. This allows for differential dissipation of heat from the header tubes so that at night water in the header tubes freezes in a controlled manner out of the ends of the header tubes. If the header tubes have an increasing internal cross- sectional area of flow corresponding to the wide end to the narrow end of the flange the control of the direction of freezing may be enhanced. The invention may be applied to other heat exchangers in which the working fluid may freeze, such as car radiators. <IMAGE>
