Title: Cable guides
IPC: B63B21/04
Filed: 1972-12-29
Abstract: 1410678 Guiding cables A BRUSSELLE 29 Dec 1972 [29 Dec 1971] 60111/72 Heading B8B A carriage 15 for guiding a cable 30 to and from a winch drum 3, is suspended from a single cross bar 20 by rollers on the carriage, engaging upper and lower tracks on the bar 20. A longitudinally grooved shaft 12 chain driven from the drum 3, rotatably drives a screw 13 slidable along the shaft 12, the screw driving a wheel secured to a shaft 17 transverse of the shaft 12 and terminating in a pinion 18. The latter drives itself along a toothed rack 19 and moves the carriage 15 therewith. The rack 19 transmits loading directly to the bar 20 and is roller link mounted thereto to be movable between upper and lower positions such that as the pinion 18 arrives at the end of the rack 19, it rides around the end to return and in so doing vertically displaces the rack. The lower portion of the carriage 15 comprises vertical rollers between which the cable passes to the drum.

Title: Cathodic protection
IPC: C23F13/02
Filed: 1978-07-18
Abstract: A cathodic protection system, for use on the hull 4 of a ship, is capable of providing a variable distribution of current to protection anodes 5, 6, 7, 8, 9, 10, 13, 14 on the hull 4. Sensing electrodes 11, 12 supply a signal indicative of the potential of the hull 4 to a controller 3 which controls the different currents supplied to various anodes or groups of anodes. The anodes are so placed on the hull that, when each is passing a given maximum current, the distribution of current flowing to the anodes is suitable for protection of the hull 4 when the ship is moving at relatively high speeds. The system is also such that at low speeds, when the total current required for protection is less than at high speeds, the controller adjusts the distribution of currents so that it is suitable for protection at low speeds. <IMAGE>

Title: Reducing compression- induced shear strain in elastomeric stacks
IPC: F16F1/40
Filed: 1978-07-31
Abstract: A laminated resilient element comprising a plurality of annular layers of elastomeric material (96b) and non-extensible material (98b) which alternate with each other and which are bonded together. The layers alternate along a common axis (92) extending lengthwise of the bearing so that the bearing can support substantial compressive loads applied generally normal to the layers. The layers include at least one elastomeric layer (Fig. 6A) which, if it were formed to have a constant modulus of elasticity throughout and were subjected to a compressive load, would experience a shear strain adjacent one of its inner and outer circumferences greater than the shear strain adjacent the other circumference. Such a difference in compression-induced shear strains would tend to cause uneven wearing of and a reduced service life for the elastomeric layer in question and for the element as a whole. To avoid or minimize uneven wear, the elastomeric layer is formed to have at least two different moduli of elasticity. The modulus of the layer is made higher or highest adjacent the circumference of the layer which tends to experience the higher compression-induced shear strain. As a result, the ratio between the shear strains adjacent the two circumferences of the layer is less than it would be if the layer had a constant modulus of elasticity throughout. The modulus of elasticity is varied by using elastomeric rings 118, 120, 122 of decreasing hardness. <IMAGE>

Title: Drive transmission device
IPC: F16H63/38
Filed: 1979-01-11
Abstract: A torque transmission device is provided in which reversal of the direction of rotation of a intermediate driving wheel 13, 13a alters which of two output wheels (11, 12) is driven. An element 15 is pivotable about the axis of the intermediate wheel 13a and supports a rotatable driven wheel 14. The element 15 is in frictional contact with the intermediate wheel 13a and rotates with it until the driven wheel 14 engages on output wheel (11 or 12). The driven wheel 14 meshes with the intermediate wheel 13a and transmits torque to one of the output wheels (11 or 12) when engaged. Reversal of the direction of rotation of the intermediate wheel 13a causes the element 15 to pivot and move the driven wheel 14 into engagement with the other output wheel (12 or 11). <IMAGE>

Title: Pole-amplitude modulation, pole- changing electric motors and generators
IPC: H02K17/14
Filed: 1979-05-03
Abstract: Each phase winding of a three phase stator winding for pole- amplitude modulation (P.A.M.), pole- changing electric motors and generators comprises two winding parts connectible in series or parallel for the different pole numbers and each winding part comprises several groups of coils, a group at or near the middle of the part having fewer coil turns than groups near the ends of the winding part. As shown each winding part has three groups with coil turn ratio 7:5:8. This arrangement adds third harmonic content to the air gap m.m.f. waveform in order to counteract low order harmonics rotating in the direction opposite to the main field, which low order harmonics would otherwise cause low frequency vibration of the machine frame, especially in large machines of high pole number. <IMAGE>

Title: Electrochromic displays
IPC: G04G9/00
Filed: 1980-02-13
Abstract: An electrochromic display cell has several electrode segments 1 spaced from a common counter-electrode 3 by an electrolyte 2 and disposed to represent different symbols according to those segments on which a coloured or effaced state is conferred by application of a current in one direction or in the other between the segments and the counter-electrode. To achieve one of the current directions a bias voltage provided by a generator 16 is applied for a fixed time by a switching circuit T1, T2 to a field-effect transistor T6 which completes a circuit through the cell 4, electrode 3, electrolyte 2 and segment 1. The transistors 6 have channel widths proportional to the segment areas so that all segments receive the same charge per unit area. The segments whose state is to change in the other direction are short-circuited with the counter-electrode by transistors T7. The display is particularly useful for the display of time data on watches.

Title: Dispensing Foamed Compositions
IPC: B05B7/16
Filed: 1980-02-20
Abstract: Foamable compositions have hitherto been dispensed from pressure vessels which contain a foamable mixture of liquid and a blowing agent, however during dispensing the foam- volume ratio drops causing process control problems. In accordance with the invention the vessel has means for maintaining, during use, a substantially constant composition of blowing agent in the vapour space in the vessel above the liquid level under a vapour pressure at least equal to the vapour pressure of the mixture, so that a foam of substantially constant foam- volume ratio is dispensed. Liquid compositions having coating or polymeric solids are capable of being foamed and dispensed with the apparatus. Foam compositions are disclosed with a synergistic blowing agent system of propane and butane for use as coatings and adhesives. <IMAGE>

Title: A Capacitive Coin Detector
IPC: G07F/
Filed: 1980-10-17
Abstract: In a capacitive coin detector capacitor electrodes (3, 4) connected to an electric circuit for detecting capacitance variation during the passage of a coin (5), are arranged on a rearwardly inclined wall (1) of a sloping coin chute having a coin support rail (2). One or more first electrodes (4) are located on the wall (1) in such a manner that the edge of a coin (5) in the chute overlaps said electrode a little or not at all, dependent on its size. A further electrode (3) is located to be closer to the centre of the coin path and has a considerable area. In this manner the capacitive coupling between the electrodes (3 and 4) via the coin (5) is substantially determined by the coin overlap of the first electrode(s) (4). With the first electrodes (4) located at the upper edge of the coin, the coin diameter can be directly checked. When they are located at the lower edge of the coin in a coin chute, where the coin support rail forms an angle of less than 90 DEG  with the wall, it is possible to check the coin thickness. <IMAGE>
