Title: Improvements in or relating to apparatus for the production of wound coils for the stators of dynamo-electric machines
IPC: H02K15/04
Filed: 1969-12-11
Abstract: 1298828 Coil winding apparatus; winding formers BALZER & DROLL KG 11 Dec 1969 [17 April 1969] 60607/69 Headings B3A and B3E Apparatus for making stator coils comprises means for moving a group of formers to a winding station, means for moving the wound formers to a removing station, and swivelling means for arranging at least two wound formers parallel to each other whereby the coils are simultaneously removed from the parallel formers. Formers 4a, 4b are wound simultaneously in winding funnels 8a, 8b, while coils on parallel disposed formers 2a, 3a are removed. When these operations are completed, the two groups of formers will be rotated 90 degrees about an axis 9, so that the formers 3a, 3b are aligned with the winding funnels and the formers (1b), 2b are disposed parallel to each other, Figs. 5c, 5d (not shown). At the next cycle of operations, the formers 2a, 2b are wound while the coils are removed from the parallel disposed formers (1a), 2a. Each group may comprise six equi-angularly disposed formers, the groups being rotated through 60 degrees between each work cycle. Two formers are wound during each cycle, but in each half revolution of the coil groups the coils are removed during two cycles only. When two formers are disposed parallel in the upper group, one former in the lower group will be aligned with one of the upper pair, and three sets of coils will be removed simultaneously. At the next removal cycle, two formers in the lower group will be disposed parallel and one former in the upper group will be aligned with one of the latter, Fig. 6 (not shown).

Abstract: 736,061. Heating coolant; turning-gear. CHRISTIANSEN, H. Oct. 15, 1953 [Oct. 16, 1952], No. 28493/53. Classes 7(2) and 7(5). [Also in Group XIII] In means for starting a liquid-cooled engine 1, Fig. 1, comprising in combination an auxiliary motor 4, such as an I.C. engine, electric motor or a steam or an air vane-motor or turbine, which can be coupled to or disengaged from the engine, and a pump 5, used only during starting, for circulating the coolant, for example water, of the engine 1, the pump is driven by the motor 4 and has an internal arrangement which produces turbulence and friction and thereby heats the coolant. A pipe 9 connects the pump 5 to the water jacket 10 of the motor 4, which in the preferred form is an I.C. engine, the outlet from jacket 10 being connected to the input side of the main-engine cylinder-coolant jackets 3, a pipe 11 returning the coolant to the pump. In operation the motor 4 is run at high speed to heat and circulate the coolant through the jackets 3 and to store energy in a fly wheel 6 ; the coolant may also be circulated through a housing, not shown, surrounding the exhaust manifold and pipe. The pump 5 limits the speed of the motor and enables the governor, normally associated with the motor 4 to be dispensed with ; furthermore a clutch 15 may be provided between the motor 4 and the pump or multiway valves and cocks not shown, may be arranged to admit air to the pump and to empty the liquid therefrom prior to cranking the engine so that the pump does not additionally load the motor 4 during this operation. A second clutch 8 is then operated so that the engine 1 is cranked through a reduction gear 7 ; when the engine 1 is self-operative valves 19 and 20 are operated to enable the water to flow through a radiator 18, the valve 20 being designed to permit air to be admitted to the pump and the liquid emptied therefrom. The pump 5 comprises a rotor 12, Fig. 2, with pins 13 on its periphery which co-operate with pins 14 on the casing to create turbulence.

Patent GB-2028062-A (GB)
Title: Data transmission system
IPC: H04L12/437
Filed: 1979-08-17
Abstract: In a closed-loop data transmission system, the terminals 1-6 of the system each send round the loop a message formed by service data and a random bit stream. Each such message is sent in a time position in a time division cycle individual to that terminal. When such a message reaches a terminal with a data message to be sent to the originating terminal that data message is encoded into the random bit stream: the now-encoded message continues round the loop in the same direction until it reaches the originating terminal where it is received and decoded. To improve system security, in addition to the links which interconnect adjacent terminals in the loop there are so-called leap-frog links each of which extends from one terminal to the next but one terminal in the loop. The invention is described in its application to a system in which the links are optical fibre cables, but the invention is also applicable where the links are of the metallic wire type. <IMAGE>

Title: Apparatus for the evaluation of coins
IPC: G07D5/00
Filed: 1979-12-12
Abstract: A method and apparatus for evaluating coins on an objective basis. A support structure (10) displays facsimile coins (17, 18, 25-27, 29) representative of the obverse and reverse sides of a given class of coins. The facsimile coins (17, 18, 25-27, 29) within the obverse and reverse groups (12, 13) are further divided into sets (20-23). Each set (20- 23) contains facsimile coins representative of a particular type of coin defect or imperfection. The facsimile coins (17, 18, 25-27, 29) within a set (20-23) are arranged according to increasing or decreasing extents to which the coin defect is exhibited. Each of the facsimile coins has assigned to it a number representative of the relative value of the facsimile coin in regard to that particular coin defect. The obverse and reverse sides of a test coin are compared with the facsimile coins within each set. The numeric values of the facsimile coins which exhibit the coin defects to the same extent as the test coin are noted and summed to arrive at a total numeric value for the coin. The monetary value of the test coin is then determined by a table which correlates the total numeric value of the test coin with its monetary value. <IMAGE>
