Title: Improvements in and relating to dynamo-electric machines
Inventor: RICHARDSON PHILIP
IPC: H02K3/51
Filed: 1965-12-24
Abstract: 1,112,129. Securing coils for dynamo-electric machines. C. A. PARSONS & CO. Ltd. 6 Jan., 1967 [24 Dec., 1965], No. 54863/65. Heading H2A. The rotor end windings 3 of a dynamoelectric machine are retained against centrifugal forces by clamping members, such as bolts 8, extending radially from at least one sleeve 6 located within the windings. In an A.C. turbo-generator, high tensile steel bolts 8 with insulating sleeves 10 and load-spreading and insulating washers 11, 12 pass through the copper or aluminium conductors and are screwed into a sleeve 6 spaced from the rotor shaft 2b at its outer end 7 to permit deflection of the shaft and secured thereto by sliding it on to the shaft then rotating it so that projections 6a, 2b<SP>1</SP> engage. The bolts are preferably staggered (Fig. 2, not shown), and support coil interconnections 19. Balance weights may be attached to the sleeve 6 at 13. Axial movement of slot wedges is prevented by a ring 14 which may act with the wedges to provide a squirrel-cage damping winding. The winding leads 17 are retained in slots in the shaft 2b by wedges 18. It is stated that because end bells are absent, cooling is more effective and consequently the end winding conductors may be of smaller cross-section than the slot conductors, but may be larger to compensate for the passage of the bolts.

Abstract: 1,222,173. Metal fuel cells. SONY CORP. 20 Nov., 1968 [20 Nov., 1967], No. 55064/68. Heading HlB. A metal fuel cell comprises a gas diffusion cathode, an electrolyte with a metal fuel powder dispersed therein, an anode for collecting current from the metal powder and means for supplying metal fuel powder together with electrolyte. As shown in Fig. 2 a cell has two oxygen electrodes 1A, 1B and an anode current collector 2 of brass. Zinc powder (fuel) and electrolyte enter the cell at 7<SP>1</SP> and are directed by baffles 12 into the space 9 between two belts 4A, 4B of nylon felt which carry the zinc powder past and in contact with anode 2. Electrolyte and zinc oxide leave the cell at 8 1 . A battery of three such cells (Fig. 3, not shown) is supplied with electrolyte/ zinc powder mixture from a storage tank equipped with a stirrer, separated by a filter from a second stirrer-equipped storage tank to which the spent electrolyte/zinc oxide is returned. Power to drive the belts, the stirrer motors and the pump is supplied by the battery. In another embodiment (Fig. 4, not shown), a single belt is used with two anode current collectors disposed one on each side. In operation the movement of the belt is periodically reversed so that fuel powder is supplied to each anode alternately.

Title: System for determining the type and location of trouble during the transmission of data signals
IPC: H04L1/12
Filed: 1972-12-01
Abstract: 1370247 Digital transmission; testing INTERNATIONAL STANDARD ELECTRIC CORP 1 Dec 1972 [1 Dec 1971] 55471/72 Heading H4P In a method of testing a transmission system; on detection of incorrect reception at a remote terminal, a request for test signal is sent to a local terminal. If test signals are received correctly the error is considered to be due to a transient condition. If however the test signal is incorrectly received, a test signal generated by the remote terminal is directed through transmitting and receiving sections to indicate whether the fault is in the line or terminal apparatus. Test signals may be transmitted in intervals between messages. A further test may be made by interconnecting line amplitude automatic controllers to test these also. Unidirectional simplex channels (Ltg) are provided between an exchange VSt and concentrator K, oppositely transmitted signals preferably having differing parity arrangements P1, P2. On correct reception parity check P2 emits a 1 signal to OR and hence to AND U2 to reset terminal R³ of counter Z21 normally advanced by clock pulses of not greater periodicity than received characters. On incorrect reception P2# 0 which switches flip-flop FE2 starting a generator GSy2 of sync. signals which are transmitted to the exchange to request transmission of a test signal. This is recognized by CP1 which removes reset from counter Z1 and starts a test signal generator GSy1. On correct reception a counter Z22 is advanced one position and after say 4 advances it is assumed that an intermittent fault only has caused incorrect reception hence FF2 is reset and P2# 1 resetting Z21; test signal request is also inhibited and exchange equipment is reset hence transmission is resumed. At this instant Z21 has not reached position 6. If 4 correct sequences are not received Z21 reaches position 6 actuating relay UM2 which disconnects lines through contacts um21, um22, through contacts (not shown) shunt the concentrator's incoming and outgoing terminals, um23 maintains GSy2 operative and um24 actuates reversing switch US. Apparatus E2 now checks signals and if correct a "good" signal is emitted at M through a substitute channel (Ltg<SP>1</SP>) (not shown). At the exchange UM1 performs a similar operation. In an alternative arrangement exchange and remote equipments may be connected to a single channel via balanced modulators hence a line fault will cause transmitted signals to be immediately directed into the receiving portion; thus differing parity arrangements are necessary for the two directions otherwise a line fault will not be apparent.

In a circuit arrangement for thread-cutting on numerically controlled machine tools a pulse emitter 1 on a tool spindle feeds pulses, dependent on rotation of the spindle, to reversible counters Z1 Z2. The counter Z1 is pre-set by a programmed numerical command from an input unit 3 to the number of threads to be cut by the tool. The counters provide a 1-signal for any stored count and a 0-signal when empty. The contents signals of the counters are fed to a selector circuit 2 carrying out the following counter control functions:- when Z1 = 1 and Z2 = 0 then Z1 counts down and Z2 counts up. Z1 = 1 and Z2 = 1 then Z1 counts down and Z2 counts up. Z1 = 0 and Z2 = 1 then Z1 is blocked and Z2 counts down. Z1 = 0 and Z2 = 0 then Z1 is blocked and Z2 is blocked. During a thread-cutting operation, the selector circuit 2 initially causes counts Z1 to count down, Z2 to count up and emits a signal to the machine tool, not shown, for switching on feed and rotation of the tool. When counter Z1 is empty and Z2 contains the pre-set count, the selector circuit 2 emits a signal for the reversal of the rotation and feed of the tool and causes counter 2 to be counted down. When both counters are empty the tool has been withdrawn from the workpiece and the machine drive is shut off. In a numerically controlled drill, or milling machine, having a co-ordinate table the positioning counters for the unused areas are employed for the thread-cutting operation.
