Patent GB-2027578-A (GB)
Title: Fishing Bait
IPC: A23K1/18
Filed: 1978-12-21
Abstract: A ready to use fishing bait composition includes up to 30% glycerine. A preferred composition also includes spice, antiseptic, colouring material and distilled water. The composition is ready to use without the need to add water to the mixture, and the composition can be stored for up to three months without a noticeable deterioration. Because the composition has a greater specific gravity than previous mixtures requiring water addition, it has a quicker sinking speed in water than previously known compositions.

Abstract: A component resistant to abrasion, tearing and traction, in particular a track element shoe for a track-laying vehicle, includes a frame 1 surrounded by a body 4 composed of a moulded and vulcanised mixture of a urethane polymer and a vulcanising agent. The component is produced by introducing a urethane polymer at 90 DEG C +/- 2 DEG C and a diamine as the vulcanising agent at 118 DEG C +/- 2 DEG C into a container preheated to 100 DEG C +/- 5 DEG C in a weight ratio of 100 parts of the urethane polymer to 13 parts of the diamine. After de-gasification, the contents of the container are introduced into a mould which is preheated to an external temperature between 80 and 110 DEG C such that its internal temperature is between 70 and 95 DEG C, any inclusions to be present in the final component being present in the mould and preheated to 80 DEG C +/- 5 DEG C. The internal temperature of the mould is maintained at its preheated value for a time sufficient to vulcanise the urethane polymer, whereafter the moulded component is removed from the mould and cured. <IMAGE>

Title: Variable inductors or resistors
IPC: H01C10/40
Filed: 1980-05-28
Abstract: A variable resistor or a variable inductor e.g. for tuning a radio transmitter uses an insulated worm gear (12) arranged to cooperate with the turns of a fixed coil (1).

The spring contact (13) also engages the shaft (7), the output connection to which is via a wiper (7A). Each rotation of the knob (6) changes the effective resistance or inductance by a discrete step. <IMAGE>

Title: Improvements in synchronous linear motors
IPC: H02K41/03
Filed: 1980-08-15
Abstract: A synchronous linear motor for driving vehicles which are at least partially magnetically supported comprises a travelling-field stator (4) extending along the entire path of travel and magnet carrier (14) mounted on said vehicle. The stator has teeth of pitch a, a winding of n phases (n=3 as shown) and the pitch t indicated is n.a. the motor is characterised in that the spacings (b2, or b1-b2 or b1-b1) between the centres of the permanent magnets (16) are such that there is no direct correspondence with the pitch t of the travelling-field stator (4). Such an arrangement reduces or substantially eliminates the difficulties in starting experienced in known linear motors in which b=t, as shown at (a). The spacing b2 shown at (b) is uniformly greater than b; or as shown at (c) a reduced spacing b1 and an increased spacing b2 are used in different sections; or as shown at (d) sections including spacing b are themselves spaced by the reduced amount b1. The stator teeth may alternatively be relatively displaced. <IMAGE>
