Title: Improvements in and relating to combination angle gauges
Filed: 1942-08-14
Abstract: 559,748. Angle gauges. HILGER, Ltd., A., DOWELL, J. H., and STERNBERG, R. S. Aug. 14, 1942, No. 11430. [Class 97 (iii)] An angle gauge combination suitable for building up of the desired angles in conjunction with an autocollimator or other optical instrument consists of one piece with three or more operative faces including three or more angles and three or more pieces with two operative faces including a single angle. Fig. 1 shows such a set consisting of one piece having three operative faces including angles of 30 degrees, 60 degrees and 90 degrees and four separate pieces each having two operative faces including angles of 1 degree, 3 degrees, 9 degrees and 14 degrees respectively. By bringing one or more of the smaller pieces on to one or other of the faces of the larger piece any angle from 1 degree to 90 degrees may be obtained. Fig. 4 shows the setting up of an autocollimator 4 to the angle determined by the angle pieces 1 and 2 on the support 3. A beam of light from a lamp 5 is directed on to the exposed face of the angle pieces and the collimator is adjusted angularly until the reflected ray passes through the zero of the eyepiece scale. Another set of angle pieces includes one large piece having four operative faces including angles of 60 degrees, 75 degrees, 90 degrees and 135 degrees together with small angle gauges of angles 1 degree, 3 degrees, 5 degrees and 10 degrees. If an angle is desired which produces a reflecting surface directed downwardly and so cannot be used with the autocollimator a small angle piece is wrung on to that face and positioned so as to be half lapped so producing a face directed upwardly and applicable for use in the autocollimator.

Title: Improvements in electric discharge apparatus
IPC: H02M7/51
Filed: 1940-07-29
Abstract: 542,393. Converting. BRITISH THOMSONHOUSTON CO., Ltd. July 29, 1940, No. 12294. Convention date, July 29, 1939. [Class 38 (ii)] [Also in Group XL] In high voltage gas or vapour filled arc discharge apparatus, in which the discharge is controlled by a grid 37, premature break-down between the control grid and the anode 19 is prevented by sub-dividing the voltage drop between them by an intermediate grid electrode 36 to which is imparted a fixed potential relationship to the anode and cathode, as by connecting it through a resistance 58 to the mid point of a potential divider 59 across the supply lines 48, 49. The functioning of the grid 36 is enhanced by the provision of a third grid 35 and means, such as the transformer 62, whereby the grid 35 is made negative relatively to the grid 36 when the control grid becomes negative with respect to the cathode. The functioning of the control grid is facilitated by an associated grid 38, energized from the same transformer 51, the resistances 54, 55 being such that the current flow in the discharge space tends to maintain the grid 37 negative with respect to the grid 38. The discharge device may have a solid cathode, or, as shown a mercury pool cathode 23 serving also as the source of ionizable vapour. A fixed gas, such as argon, may be used as an auxiliary ionizing medium. The cathode is carried in a metal container 12 insulated from the main body of the envelope 10 by an insulator 13, which is protected from the deposit of condensed mercury, by a drip baffle 25. The cathode lead is a heavy stud 27, the ignition electrode 28 is of the immersion type, and an auxiliary anode 31 has a lead 32 protected from the discharge by an insulating sleeve 33. The envelope 10 is surrounded by a cooling coil 16 and has an exhaust duct 17 for connection to an evacuating system. The anode 19 is substantially enclosed by the grids 35, 36, and the leads consist of concentric tubes 20, 40, 41, and metal lead-in rings 42, 43 having glass-tometal seals with the envelope. The seals are protected from the discharge by shields 44. Specification 488,209, [Group XL], is referred to.

Title: Improvements relating to remote control circuit breakers and the like
IPC: H01H13/20
Filed: 1920-05-04
Abstract: 167,543. Hall, J. May 4, 1920. Automatic circuit-breakers are closed electromagnetically from a distance by closing a handoperated push-button or equivalent switch which is electromagnetically pulled home, against yielding fixed contacts, thereby relieving the retractive pressure of the contact-member and causing an involuntary slight further depression of the push-button, this depression serving mechanically to de-clutch the push-button from its switch spindle so that the push-button switch cannot be held closed. As shown in Fig. 1, the push-button c is provided with retractive springs and carries pivoted clutch members d which engage with a driving stop e on the rectilinearly-moving spindle a provided with the bridging contactmember b for engagement with the plunger contacts k in the closing circuit of the main circuitbreaker located at a distance. The spindle carries also an armature j which, when the button is pressed so as to close the circuit at k, is drawn up to the electromagnet i energized by the closure of the circuit-breaker. This further movement of the contact spindle while the hand pressure is maintained on the button allows a further involuntary inwards movement thereof, and, in this movement, the clutch members d. engage the fixed stops f and are carried free of the driving connection with the switch spindle so that the switch cannot be maintained closed by hand if the electromagnet is de-energized by the opening of the main distant circuit-breaker or overload.
