Title: Improvements relating to electric converting apparatus
IPC: H01T11/00
Filed: 1932-01-22
Abstract: 400,634. Converting. MARX, E., 3, Rankestrasse, Brunswick, Germany. Jan. 22, 1932, No. 2070. Convention date, Jan. 22, 1931. [Class 38 (ii).] Spark-gap apparatus for converting polyphase A.C. to D.C. or vice versa comprises asymmetric spark-gaps FR, FS, FT in each connection between the phases R, S, T of the A.C. system and the D.C. system B, there being associated with each gap provision for initiating a discharge at a predetermined point in the A.C. voltage wave. Such provision comprises a condenser Cz connected between phases through a resistance Rz. Each condenser is associated with an auxiliary discharge gap which includes a rotary electrode A driven synchronously with the A.C. network. Thus at a predetermined point in the cycle of A.C. voltage determined by the setting of the rotary electrode, the condenser may be caused to set up an oscillatory discharge in an inductive winding DR which produces a voltage impulse sufficient to break down the main gap. This impulse is diverted from the transformer by the condenser CR, and the resistance Rz prevents an interphase short circuit.

Title: Improvements in and relating to metal cutting machine tools
IPC: B23Q5/40
Filed: 1946-01-22
Abstract: 608,639. Drilling-machines; planing. SOC. GENEVOISE D'lNSTRUMENTS DE PHYSIQUE. Jan. 22, 1946, No. 2134. Convention date, Oct. 30, 1945. [Class 83 (iii)] [Also in Group XXIV] In a metal-cutting machine tool having two tool holders separately traversable on a common screw, one by rotation of the screw and the other by rotation of its feed nut on the screw, the feed nut is coupled to a counter-nut and a spring is fitted between the two nuts to ensure that they rotate together with the screw unless separately driven. A drilling or planing machine has a crossbeam 7, Fig. 1, with a slide carrying a vertical tool holder 8 and the beam is traversed on uprights 3, 4 by screws 10, 11 rotated by irreversible worm gears 17, 18 and engaging nuts 22, 23 fixed in the cross-beam. A saddle 21 having a horizontal tool holder 20 is also traversed on the screw 11, when the latter is not rotating, by engaging the drive from a motor 40, Fig. 3, or hand wheel 41, with a feed nut 24 rotatably mounted in the saddle. The nut normally rotates with the screw 11 because of friction created in the threads by a counter-nut 26 engaging the feed nut by a tongue and slot 27 and by a spring 29 between the two nuts. The handle 34 for engaging the drive may also control the operation of the motor.

Catches, spring; fastenings for sliding windows. -A pivoted catch-member on the upper rail of the lower sash adapted to be swung into a notch in the side rail of the upper sash, is secured against release by a spring - pressed sliding- bolt which mav be mounted on the catch to engage a recess in the notch in the side rail, or in the notch to engage a recess in the end of the catch. The catch 3 is pivoted at 2 on a plate 1 with a recess 17 for the foot of the catch, and engages a recess or housing 6. In the form shown, a spring-pressed bolt 9 operated by the finger-piece 11, is mounted on the catch and engages a recess in the housing 6. A spring may be mounted in the recess 17 to actuate the catch. A flap 14 may be pivoted to the catch below a projection 16 so that as the catch engages, the flap slides along the flanges of the plate 1 and engages a recess in the housing 6 to prevent the entry of a knife between the sash rails to force the catch out of its engaging position.

Title: Fluid pressure brake apparatus for railways
IPC: B60T15/30
Filed: 1956-01-26
Abstract: 780,469. Fluid pressure railway brakes. WESTINGHOUSE AIR BRAKE CO. Jan. 26, 1956 [Feb. 8, 1955], No. 2586/56. Class 103 (1). A fluid pressure brake apparatus of the type comprising a brake pipe 1, a brake cylinder 5 and means 7 defining a quick service communication including passages 91, 128, 132, 134, 34, 35 and 36 through which fluid under pressure may be withdrawn from the brake pipe is characterized by the provision of valve means 126 having a cut-off position for closing said quick service communication, and fluid pressure motor means 123, 143 for controlling operation of said valve means, said motor means being responsive to an increase in brake pipe pressure assisted by a spring bias 129, 144 acting in opposition to brake cylinder pressure and a constant pressure 124 during a brake releasing operation to shift said valve means from cut-off position towards a normal position for permitting fluid flow through said quick service communication. It has been found that with distributer valves having a quick service reduction insuring valve device 18 of the kind described in Specification 766,406 there is a tendency on freight trains composed of a large number of unbraked cars for the auxiliary reservoir pressure and hence the pressure in chamber 85 of the corresponding quick service valve device 11 to be somewhat higher than the brake pipe pressure acting in chamber 86, this condition being particularly likely in France where it has been proposed to use a Continental size auxiliary reservoir to shorten the travel of a brake cylinder piston. If the auxiliary reservoir pressure should be slightly higher than brake pipe pressure at the time the reduction insuring slide valve 126 is shifted to its intermediate position, instead of the quick service volume' 92 being vented, as intended, fluid under pressure may be locally released from the brake pipe into the substantially vented brake cylinder device 5 until brake pipe pressure has been reduced the assumed 6 p.s.i. below control reservoir pressure. To avoid this condition when the slide valve 126 is in its normal position, the cavity 134 is adapted to be in register with two paralle arranged ports 135, 136 constantly open to the passage 34.

Title: Method of refining oil-wax mixtures
IPC: C10G73/42
Filed: 1932-01-29
Abstract: Oil-wax mixtures containing 5 per cent or more of paraffin wax are refined, prior to separation by known processes into wax and oils, by treating the melted mixture at 180 DEG  C. or lower with anhydrous chloride of aluminium iron, zinc, tin, antimony, or chromium, or mixtures thereof, and separating the sludge as by settling, then filtering through an absorbent e.g. fuller's earth or bauxite or by settling, centrifuging, and then filtering.  The pressure is preferably slightly below atmospheric but may be atmospheric or slightly above.  The sludge may be treated to recover the chloride or to make asphaltic bitumen.  Mixtures specified for treatment are reduced or topped crude oil, wax-containing distillates, scale wax and sweated scale wax. Specified processes of separating the wax from the oil are distillation, sweating, centrifuging and pressing with or without blending with naphtha and with or without the use of a filter aid. In examples: (1) Crude oil topped to 300 DEG  C. is agitated for 10 min. at 135 DEG  C., first with 1 per cent and then twice with 2 per cent of aluminium chloride; the sludge is allowed to settle out, and the oil is separated, filtered through fuller's earth and distilled under reduced pressure to obtain gas oil, a distillate from which wax scale and lubricating oil are obtained by pressing, and a residue from which viscous oil and crude petroleum are obtained by cold settling with naphtha.  (2) Sweated scale wax M.P. 135.7 DEG  F. is violently agitated at 100 DEG  C. with 0.25 per cent of aluminium chloride for 75 min., and allowed to settle; the wax is separated and filtered through fuller's earth.
