Title: Circuit breaker and safety trip combination
IPC: H02B1/056
Filed: 1972-05-01
Abstract: 1382311 Switchboards: automatic circuit breakers SQUARE D CO I May 1972 [7 May 1971] 20072/72 Heading H1N On removal of a circuit breaker 10 from the mounting pan 1 of a switchboard of the type disclosed in Specification 1,181,893, a push rod 50, which projects from the base of the circuit breaker and co-operates with a stationary cam surface 60 on the mounting pan, moves downwardly to actuate a push-to test pin 36, which is accessible to a suitable tool via a passage 38, to trip a trip bar 28 so that the circuit breaker is opened before plug-on contact jaws 20, 21, and 22 are disconnected from the stack of parallel insulated bus-bars 4,5,6,7. The circuit breaker 10 is a modification of the circuit breaker described in U.K. Specification 1,094,377 except that it has the manual push-to-test tripping feature and the trip interlocking rod 50. Each terminal strap 18 is connected to a respective pair of contact jaws 20, 21 and 22 by way of the circuit breaker contacts. A U-shape cone 24 surrounds each strap 18 and co-operates with an armature 30 biased upwardly by a spring 31. On overload the armature 30 is attracted causing a cap 34 on a rod 33 carrying the armature 30 to rock the trip bar anticlockwise against B spring bias to trip the circuit breaker. The push-to-test pin 36 is biased upwardly and rests on the lower end of the armature rod 33. Thus depression of pin 36 by a suitable tool trips the circuit breaker. The push rod 50 has a pair of arms 51 projecting laterally which co-operate with a locking washer 53 on the pin 36. A spring 55 biases the rod 50 downwards and is of such strength that when the push rod 50 is unrestrained by the cam surface 60 it overcomes the spring biases of the test pin 36 and armature 30 to trip the circuit breaker. In an alternative embodiment (Fig. 5, not shown), the cam surface is provided on a load terminal housing mounted on the pan 1. Each strap 18 is provided with a knife contact which enters a slot in the terminal housing and co-operates with fixed contact jaws in the terminal housing when the circuit breaker is connected to the bus-bars.

Abstract: 1337826 Rear view mirrors I H CATHCARTJAMES 19 April 1971 [13 Feb 1970] 20145/71 Heading B7J To ensure that drops of water or other objects do not collect on the reflecting surface of a motor vehicle rear view mirror 26, the mirror is fixed to a mounting plate 24 and a shaft 22 rotatably mounted in a bearing 20 supported in a housing 12 by plates 16, 17, 18, rotation being caused by the movement of air, as shown by the arrows 42, through the annular space defined by a tubular guide member 36, which rotates with the mirror, and past vanes 34 radially disposed around the periphery of the mirror. To assist rotation, an electric motor 70 may be attached to the shaft 22. Due to the narrowing of the space defined by the guide member 36 air is accelerated past the vanes so that the mirror is rotated sufficiently quickly to remove water when the vehicle is moving slowly. The housing 12 and the support plates 16, 17, 18 may be formed integrally, and the housing may be aerodynamically shaped to assist in directing air towards the vanes. The mirror may be mounted adjustably in a cup 46 and locked in position by a nut 54, or alternatively the housing may be fixed directly to the vehicle.

Abstract: 1304460 Electro-medical apparatus AMERICAN OPTICAL CORP 30 April 1970 [30 April 1969] 20947/70 Heading G1N In an ECG monitoring system, in one embodiment, Fig.7 (not shown), the ECG signal is differentiated and signals A, B, C, D respectively equal to the products shown in Fig. 1 are produced. The '+' and '-' signs represent the positive and negative components of the signals shown. The sequence of pulses occurring in these signals characterizes the ECG waveform, e.g. waveform W9 has the sequence A and D occurring simultaneously followed by C. In an alternative, Fig.14 (not shown), the signals A, B, C and D may be respectively equal to +e, -e, -<SP>de</SP>/ dt , and +<SP>de</SP>/  dt . Since A never occurs without D and B never occurs without C. The sequence of signals A, B, C, D are applied to a recognition logic circuit, Figs.11A and 11B (not shown), which determines the sequence, and when a -STROBE pulse is produced at the end of each ECG waveform, the final state of the sequence characterizes the waveform. In operation, during an initial fifteen second learn process a morphology detectron circuit, Figs.12A and 12B (not shown) stores the end states provided by the recognition logic circuit for the types of ECG waveforms occurring during the learn period. These ECG signals are regarded as "normal" for the patient concerned. In subsequent monitoring any ECG waveform which provides an end state not stored is regarded as "abnormal" and a three-second timer is triggered. The ECG signal is applied to a two-second tape loop connected to a recorder which is triggered by the timer.  There is also provided an interval detector circuit, Fig. 9 (not shown), which compares the interval between ECG waveforms with a running average of past ECG waveform intervals, and early or late waveforms which deviate a preset percentage from the average are detected to trigger the three-second timer. An area detector circuit, Fig.10 (not shown) is provided to compare the width (i.e. area of rectified ECG signal) of each ECG waveform with a running average of the widths of past ECG waveforms. A count of the number of premature ventricular beats may be provided. For a VPB to be detected there are two requirements (a) an indication that a true compensatory pause exists, and (b) either an excessive ECG waveform area is detected or a waveform shape other than one of those learned exists. A timing circuit, Fig. 8 (not shown), is provided to provide all the timing pulses for the circuits shown in Figs.7 and 9-12B (not shown), e. g. by detecting the R wave of each incoming ECG waveform. Circuitary is provided to inhibit operation of the circuitary in case of excessive noise.
