Figure 3A shows a section of the left hand synchronizing device, the synchronizing ring 21 having a land 34 formed on it and the hub 20 supporting the sleeve 23 by means of three axially extending parts such as 29a, in axial grooves of the sleeve 23. The ends 39 and 40 of the split ring 24 are spaced on either side (and shaped to conform to) the land 34 and the part 29a. When the sleeve is moved leftwardly the interaction of the conical surfaces of ring 21 and the gear 12 causes the spring to expand in opposition to the leftward force of the sleeve 23, tending to cause the spring to contract, the force on the spring from the ring 21 being from the band 34 abutting (due to it moving circumferentially on contacting surface 18) end 39 of the spring, the opposite end (at 40a) of the spring abutting the part 29a. On synchronization the force of the sleeve 23 is permitted to contract the spring, removing the free play shown in Fig.3A and allowing (due to the spring's decreased diameter) the sleeve to move further to the left to engage the teeth 16.

Abstract: 1391319 Lifting devices H F DALGLISH 15 Dec 1972 [6 Jan 1972] 58444/72 Heading B8H A device for lifting a roll of material C comprises a boom 20 which is mounted on mounting brackets 11, 12 which are vertically movable on the mast 10 of a truck B, the boom 20 being rotatable about a vertical axis defined by a shaft 19, there being a probe 21 having expansible jaws 25 mounted on the boom 20 for engagement within the core of the roll C while a flood light is mounted on the boom 20 which, in the position shown in Fig. 1, projects light on to the top of the roll C thus forming a pattern 31, the light which is reflected from the top of the roll being detected by a photo-cell 29 located in the tip of the probe 21. When the probe 21 is located over the hollow core of the roll the photo-cell 29, which is now unable to receive the reflected light, causes a horn 55 to be actuated through a relay 54. The truck operator then knows that the probe 21 is correctly placed for insertion into the roll core, and the probe 21 is then lowered into the core. A roll clamping plate 32 which is curved in its transverse cross-section is mounted by means of pivotally connected levers 35, 36 to a plate 15 depending from the rear of the boom 20. Initially the plate 32 is extended forwardly under the action of a ram 45 to engage with the periphery of the roll C thus causing the boom 20 to pivot and to extend directly towards the centre of the roll C. When the roll C is lifted it is clamped between the probe 21 and the plate 32.

Title: Use of unilluminated solar cells as shunt diodes for a solar array
IPC: H01L31/042
Filed: 1969-12-01
Abstract: 1,243,109. Solar batteries. NATIONAL AERONAUTICS & SPACE ADMINISTRATION. 1 Dec., 1969 [19 Dec., 1968], No. 58543/69. Heading H1K. A solar cell array comprises at least two batteries 10, 32 each having a plurality of series connected pn junction solar cells, 19, 21, 23, 25 and 34, 36, 38, 40, arranged so that one 10 of the batteries is illuminated whilst the other 32 is shaded, each solar cell of one battery being connected in parallel and opposite polarity with a cell in the other battery so that if a solar cell 21 in the illuminated battery 10 becomes disabled the solar cell 36 connected in parallel with it in the shaded battery 32 provides a shunt path around it. The polarity of the voltages developed by the illuminated solar cells is such as to reverse bias the equivalent diodes of the unilluminated solar cells and prevent shorting under normal operation, but if one of the solar cells in the illuminated battery is shaded and ceases to generate a voltage the equivalent diode of the shaded solar cell connected in parallel with it is forward biased and conducts, thus ensuring a continuous current path. The batteries may be mounted on a space craft.

Patent GB-2008554-A (GB)
Title: Stabilisation of supercooled fluids
IPC: C09K5/06
Filed: 1978-10-30
Abstract: Supercooled fluids such as hypo may be packaged and used as sources of heat at a predetermined temperature, recrystallization being triggered when release of heat is desired. In order to render the supercooled hypo stable, it is heated sufficiently to ensure that minute crystals of all phases, especially the dihydrate are melted. The specific gravity and optionally the pH are then adjusted to 1.595 and 8-8.5 respectively, for example by adding water and an alkali, thereby to stabilize the fluid when it is supercooled below the melting point of hypo. The water also ensures recrystallization as the  alpha -pentahydrate, thereby maximizing the release of heat.

Title: Method of processing the read signal from a data carrier and arrangement for putting the method into practice
IPC: G11B5/09
Filed: 1979-04-05
Abstract: The method operates to hold constant the mean level of the read signal from coded information contained in a data carrier, such as a magnetic disc, and to generate a signal which is slaved to the amplitude of the read signal which enables the detection thresholds for the read signal to be adjusted as a function of the actual level of the said read signal. The level of the read signal is memorised by a capacitor 4 which is connected to read amplifier 2 when the read signal represents the first six adjusting magnetic changes in a zone. The memorised signal is used to cause generation of two threshold levels by a generator 10 and a signal to control the amplification of read amplifier 2 by a comparator 9, filter 11 and field effect transistor 13. When the read signal is initially received a switch 8 is opened to alter the time constants of the circuit including capacitor 4. When a change of read head is made, e.g. a change between the read heads on opposite side of a disc, switch 12 is opened and switch 14 closed so that the gain of read amplifier 2 is a maximum. <IMAGE>
