Title: Improvements in wind instruments of the reed type and, in particular, in saxophones
IPC: G10D9/04
Filed: 1979-01-11
Abstract: Musical wind instruments, particularly those with a reed carried at a mouth-piece or holder (5), such as a saxophone, often have an upper hole (2), or so-called "second mouth-piece", capable of selective opening/closure to extend the range of the instrument beyond that available from its normal key mechanism (not shown). The invention provides at least one further hole (6) with a selective closure (7) operated via a suitable linkage (8, 9). This further extends the range of the musical instrument, usually by an octave. <IMAGE>

Title: Direct current multiple load control circuit
IPC: H02P5/68
Filed: 1979-07-20
Abstract: A direct current circuit for controlling two pairs of servo motors (M1, M2; M3, M4) controlling the flight of a flying body consists of two bridge circuits with power amplifiers (T11, T12, T13, T14; T21, T22, T23, T24) in the arms of the bridges, the servo motor pairs (M1, M2; M3, M4) being connected across respective bridge diagonals (C1, D1; C2, D2). The bridge circuits are connected in parallel by their other diagonals (A1, B1; A2, B2) across a direct current source and the central points (P1, P2) between the servo motors are connected to a centre tap on the direct current source. A control unit (KV) issues command signals (UI, UII, UIII, UIV) for the control of the power amplifiers (T11, T12, T13, T14; T21, T22, T23, T24) in accordance with input signals (UN, UR, UG) representative of pitch, roll and yaw. A further input signal (Jmp) representative of current flow into or out of the centre tap (O) on the direct current source is used to ensure that the current into or out of the centre tap (O) is substantially zero so that the weight of the current source may be minimised. <IMAGE>

Title: A shear plate for a dry-shaver
IPC: B26B19/42
Filed: 1979-09-14
Abstract: An improved shear plate is provided for a dry-shaver having a movable cutting unit which comprises a plurality of cutters (23) and a corresponding plurality of hair-pulling elements (25) each arranged in front of one of the cutters for movement therewith relative to the shear plate. To enhance the pulling action of each hair-pulling element, the wall (32) of each hair-entry aperture of the shear plate, at the part of the boundary of each aperture where the cutters cooperate with the shear plate to cut off the hairs, is formed with a portion (36) which slopes inwardly of the aperture from the inner side (34) of the shear plate towards the outer side (39). The effect of this sloping portion is to augment that component of the reaction force of the hairs on the hair-pulling elements which gives these elements their pulling action, and also to reduce the frictional resistance of the shear plate to the movement of the hairs by the hair- pulling elements. <IMAGE>

Title: A sprue bushing for an injection moulding apparatus
IPC: H05B3/42
Filed: 1979-10-10
Abstract: A sprue bushing 10 has a central runner passage for conveying melt from the molding machine or manifold to a mould cavity 13. The runner passage extends through an elongated inner core portion 14 having an undulating outer surface 24 in the form of a helical ridge 26 with a rounded cross section. A single element electrical heating element 16 with a helical configuration is located over the core portion 14 and an outer shell portion 18 is cast over them to form the sprue bushing as an integral unit. The inner core portion 14 is formed of a high strength material such as a beryllium nickel alloy and the outer shell portion 18 is formed of a highly conductive material such as a beryllium copper alloy. The coils of the heating element are separated from each other and threaded in the opposite direction to the helical ridge on the outer surface of the core portion. This allows the highly conductive material to surround the heating element with no insulative air gaps. <IMAGE>

Title: A device comprising two meshing gears to act as a pump and/or motor
IPC: F04C2/08
Filed: 1980-02-04
Abstract: Two meshing gears 8, 9 are mounted on shafts 6, 7 supported in a body 1 by means of separate bearing sleeves 11, 12, 13, 14, against which the faces of the gears 8, 9 abut. These sleeves can move in the axial directions of the shafts, and are sealed against the faces of the gears 8, 9 by the pressure prevailing in the gear chamber. The pressure is conducted through pressure- equalizing holes 32 into partial pressure zones isolated from axial equilibration zones by seal members 22, 26, 27, 28. The pressure- equalizing holes 32 are located in the bearing sleeves 11, 12, 13, 14, most suitably at the essentially central point of the pressure increase area corresponding to the approximately operating condition of the device so as to eliminate any undue tilting of the bearing sleeves 11, 12, 13, 14 in varying operating conditions. The plane sides of the bearing sleeves 11, 12, 13, 14, abutting on the faces of the gears 8, 9, have coatings 40 containing PTFE-plastics or other plastics material such that the coatings are at least partially elastic and have a low coefficient of friction against the gears 8 and 9. <IMAGE>

Title: Apparatus for subjecting a workpiece to a jet of liquid
IPC: B24C9/00
Filed: 1980-03-15
Abstract: Apparatus for removing solid matter from a workpiece by directing a jet of liquid from a nozzle 12 onto the workpiece supported on a platform 11 has a first tank (16) into which liquid drains from the workpiece and in which pieces of solid matter removed from the workpiece accumulate. Water containing suspended particles overflows from the first tank (16) into a conical tank (19) where the water is directed towards a narrow, lower part of the tank. The water flows upwardly through a wider part of the tank and overflows into a third tank from which it is pumped through a cyclone separator to a reservoir (21). Water projected at the workpiece is pumped from the reservoir. Suspended particles settle out of the water in the conical tank as the upward velocity of the water decreases in the wider part of that tank. Abrasive particles may be supplied through a conduit 14 to the nozzle which is supplied with liquid from the reservoir 21 by a pump 28. <IMAGE>

Patent GB-2100184-A (GB)
Title: Friction welding apparatus
IPC: B29C53/00
Filed: 1982-02-05
Abstract: A friction welding apparatus for joining thermoplastic materials, such as a reinforcing plate to the inner surfaces of oppositely disposed legs of a generally U-shaped workpiece, includes flexible force applying means for applying a force in a direction normal to the direction of relative motion between the parts but in the plane of the mating surfaces for urging the legs of the U-channel into intimate contact with the edges of the reinforcing plate. During a weld time interval the parts undergo relative linear reciprocating motion while being urged in intimate contact by the flexible force applying means which causes the mating surfaces to soften under the influence of friction. After the weld interval, the parts are returned to their original position and are held in forced contact for a time sufficient for the mating surfaces to solidify. Upon solidification the force ceases and the welded parts are removed from the apparatus.
