Title: Baler auxiliary drives
IPC: A01F15/08
Filed: 1978-09-07
Abstract: In an agricultural pickup baler, the twine-tying or wire-twisting mechanism is driven by a shaft whose input end meshes directly with a gear carried on the end of the shaft which drives the ram crank arm, and whose output end meshes directly with the rotating twine-tying or wire-twisting mechanism itself. Said mechanism is thus drivingly connected to the ram crank arm through only two pairs of meshing gears. Said gear carried by the output shaft is itself located on the outside of the main gearbox housing. <IMAGE>

Title: Improvements in or relating to electronic damping systems
IPC: H01P1/12
Filed: 1978-09-09
Abstract: The invention provides a waveguide switch arrangement in which an electric motor 8 is arranged to drive the switch 1 from one position to another and means are provided for utilising the electric motor to provide a braking effect as the switch approaches the other position. The motor is driven in a chosen direction from a power supply 11 via a differential amplifier 10 governed by a bridge 10 and a bistable 18 which determines the direction of unbalance of the bridge. After a given period of acceleration determined by a relay 22 the power to the motor is interrupted and the motor is short-circuited by a switch 25 for a short period determined by pulse generator 23 followed by a period determined by pulse generator 26, in which the drive to the motor is reversed. The motor is subjected to a short circuit when in the rest position. <IMAGE>

Title: Automatic welding system
IPC: B23K9/095
Filed: 1978-09-18
Abstract: An automatic welding system comprises a sensor carriage Kg which follows a seam L to be welded by means of a seam scanning sensor F1 and also a height (Y direction) sensor F. The positions of X and Y slides of the carriage are sensed at Sx, Sy as the carriage proceeds along the seam and provides inputs to the welding head carriage Ke after a delay at X1, X2. This delay compensates for the lag of the welding head behind the sensor. The width of the weld seam is also measured and similarly delayed at X3 to provide an input for weld speed, wire feed and weld voltage control BGD. <IMAGE>

IPC: A01C7/04
Filed: 1979-04-23
Abstract: In apparatus for dispensing seeds a capture element 12 is driven in a cycle of movement in which it dips into a reservoir 13 of seeds suspended in water, captures a seed on a capture orifice 15 of the capture element 12 by means of suction applied to a conduit 14 leading to the capture orifice 15, moves from the seed reservoir 13 to release location 23, and releases the seed by application of a pulse of water to the said conduit 14. The suction is applied continuously to the conduit 14 leading to the capture orifice 15, and release of the seed is achieved by applying a pulse of water sufficient to overcome the applied suction. In a preferred form the seed reservoir includes flow means for supplying an upwardly directed flow of water in the seed reservoir 13 carrying a stream of seeds upwardly towards the surface of the water for capture by the capture orifice 15. The method and apparatus may be used for dispensing discrete objects other than seeds, may be used for dispensing objects in a dry state, and may be used to dispense more than a single object at a time. <IMAGE>

Title: Charging Apparatus
IPC: H02J7/00
Filed: 1980-06-30
Abstract: A charging current (P,N,T) from an external electrical source (V) is supplied to charging control means (R1, R2). A first and second control means for providing charging current at first and second charge rates are connected to terminal adapting means (P1,P2,N1,N2).

Title: Method of making games racket frames
IPC: A63B49/10
Filed: 1980-08-19
Abstract: A method of making a games racket frame by injecting thermoplastics material into the space (13) between a fusible core (14) and a mould at a temperature above the melting point of the core. The core (14) is shaped to have locating lugs (15) to abut against the internal walls of the mould and hold the core in the desired position. The moulding is allowed to set and the core then melted out by raising the temperature sufficiently for that purpose but insufficiently to deform the moulding. The lugs (15) enable the core (14) to be located in the desired position in the mould and to resist displacement from that location during injection. The holes formed in the wall of the frame because of the abutment of lugs and mould wall can conveniently be utilized as stringing holes.

Patent GB-2091238-A (GB)
Title: Neutralising alkaline residues
IPC: C04B22/06
Filed: 1981-01-16
Abstract: Alkaline residues in a hydraulic cement are neutralised by releasing into the cement after setting an acid material. This may be achieved by dispersing in the cementitious composition a powdered or granular water soluble composition which on dissolution releases an acid substance whose dissolution rate is such that the neutralising process takes place primarily after setting of the cement. Typically the neutralising agent comprises an alkali metal/ phosphorus pentoxide glass which is incorporated in the cement prior to or after mixing with water. The pH of the glass is adjusted by controlling its phosphorus pentoxide content, and the dissolution rate is determined by including e.g. calcium oxide and/or alumina to the glass composition.
