Filed: 1966-06-07
Abstract: 1,193,964. Fluid pressure actuators for disc brakes. GIRLING Ltd. 6 June, 1967 [7 June, 1966], No. 25222/66. Headings F2E and F2F. [Also in Division F1] In a metal-walled capsule actuator for disc brakes (Division F2), the actuator is formed from two shells having peripheral flanges which are mounted back to back with the flanges in contact and a plate 27 (Fig. 3) is provided in the capsule actuator which contacts both walls of the actuator in the inoperative state. At least one face of the plate 27 is provided with grooves to ensure satisfactory distribution of fluid and the plate prevents inward collapse of the capsule actuator beyond the amount determined by the thickness of the plate. The flanges of the shells of the capsule actuator are joined by welding or brazing around the edges of the two flanges. Fig. 1 shows a disc brake comprising a torque carrier 10 in which two capsule actuators 20 and 22 are sandwiched between the backing plates 16 and 18 of friction pads 12 and 14 and two pressure plates 24 and 26, respectively, such that pressurization of the capsule actuators moves the friction pad assemblies 12 and 14 into frictional engagement with the brake disc 82. The pressure plates 24 and 26 are connected together via shafts 32 and 34, respectively, each screwed at one end and which pass through lugs in the torque carrier 10. The two shafts 32 and 34 are connected for rotation together by sprockets 52 and 54 and a chain 56. The shaft 32 is intended to be driven by an automatic adjuster mechanism 58. The chain sprockets 52 and 54 and the chain 56 could be replaced by reciprocating linkage with a pawl and ratchet mechanism between the linkage and each shaft. Alternative constructions of the capsule actuator are disclosed in Fig. 4 (not shown) in which, for instance, the capsule actuator shells have bulbous margins adjacent the flanges to ensure minimum resistance to expansion of the capsule or the shells may have inwardly-directed flanges welded or brazed together.

Abstract: 371,742. Brake shafts. FORD MOTOR CO., Ltd., 88, Regent Street, London.- (Assignees of Sheldrick, L. S. ; 1424, River Lane, Dearborn, Michigan, U.S.A.) Sept. 8, 1931, No. 25243. Convention date, Sept. 8, 1930. [Class 103 (i).] A brake-operating cross-shaft particularly for vehicles is formed from a tube of relatively large diameter to reduce torsion and bending in the operation of the brakes, the ends being reduced to provide the bearings. In making the shaft, the section 11 at one end is first slightly reduced by forcing through a die to permit ready assembly of the operating-arm 17 on the main unreduced part of the shaft. The end parts 12 are then further reduced as by a drawing operation to provide the bearings of the shaft, this operation resulting in thickening of the metal at these parts. For application to an automobile, the shaft may then be bent as shown at the central part to clear the torque tube 16. Arms 18 connected to the brakes are secured to the ends of the shaft.

Title: Manufacture of petroleum coke
Inventor: FAUCHIER PAUL WARREN
IPC: C10B55/00
Filed: 1963-06-25
Abstract: In the production of petroleum coke by subjecting a heavy petroleum residuum to delayed coking and removing the raw coke by jets of high pressure water, coke fines are first separated and then homogeneously redistributed with the coke particles to facilitate subsequent treatment, by treating the raw coke/water mixture in the following manner: the coarser particles of raw coke are removed from the coke/water mixture, preferably by dragging coarse particles up an inclined apron as the slurry descends, the slurry of coke fines is separated by decanting and filtration, the water so removed is re-circulated to provide the source of high pressure water for removing coke from the coker and the recovered coke fines are uniformly re-combined with the coarser coke particles.  The coke may be prepared from a heavy petroleum residuum charged at 850 DEG  to 950 DEG  F. to coking drums operating at 20 to 80 p.s.i.  The coke removed from the coker is subjected to the filtration procedure above described and the combined mixture of coarse and uniformly distributed fines may then be passed to a rotary calciner operating at 2500 DEG  F. counter-current to hot gases.ALSO:A slurry of coke fines is gravitationally settled from the coke washed from a coking drum.  The slurry is settled, the water decanted and the fines filtered.

Title: Capacitor charging circuit
IPC: H03K17/60
Filed: 1968-05-29
Abstract: 1,216,877. Switching circuits; light modulators. INTERNATIONAL BUSINESS MACHINES CORP. 29 May, 1968 [14 July, 1967], No. 25634/68. Headings H3T and H4F. In a capacitor charging circuit comprising a positive charging circuit 42, a negative charging circuit 44 and the capacitor, such as a crystal 46 connected in parallel, the positive and negative charging circuits 42, 44 each include a diode 64, 36, a Zener diode 40, 38, and a respective voltage pulse generator 47, 48, the pulse generators are operated alternately and the diode and Zener diode in each charging circuit are poled such that discharge of the capacitor is blocked by the diode in one charging circuit and by the Zener diode in the other charging circuit in accordance with the polarity of the capacitor voltage. To positively charge the crystal, which may be used to change the state of polarization of linearly polarized light, a switching pulse 86 (Fig. 4) is applied at 50 to turn on switching transistor 54. This generates a pulse in secondary 62 which is passed by diode 64 to charge the crystal 46. The Zener diode 40 conducts and maintains the voltage across it, e.g. at 2000 volts. The diode 64 blocks discharge of the capacitor and the Zener voltage across the Zener diode 38 blocks discharge via the negative charging curcuit 44. Leakage of charge is compensated by applying sustaining pulses 88 at 58 which produce an output Fig. 4e, having a slight sawtooth superimposed on the load voltage. Similarly the negative charging circuit is operated by switching transistor 74 when a switching pulse 90 and sustaining pulses 92 are applied at 70, 78. The transformer 48 is wound so that the upper end connected to diode 36 is negative. The capacitors 68, 84 act as filters. The Zener diodes 40, 38 may consist of a plurality of series connected Zener diodes. The amplitude and duration of the pulses induced in the charging loops may be controlled by controlling the amplitude and duration of the current through the primary of each transformer.

Abstract: 832,901. Forming and transporting dough pieces. DCA FOOD INDUSTRIES Inc. Aug. 11, 1958, No. 25739/58. Class 87(2). [Also in Group VI] Dough for the production of fried cakes is formed and cut into pieces of predetermined shape in a mechanism 74 which has a discharge opening above a conveyer 18, 19 which moves through a cooking device 10 and the mechanism is reciprocated across the direction of movement of the conveyer in a path which has a longitudinal component in that direction, the speed of such component being equal to the speed of the conveyer. The mechanism 74 is fed from a hopper 73 and may be of any known construction. The cooking device 10 is also of known construction, including a trough 11 which contains hot oil through which the parallel chains 18 of the conveyer move, blades 19 being carried between the chains, spaced to form frying cells. The hopper 73 and mechanism 74 are carried on a carriage 56 which is slidable along a frame 28. The frame 28 can be set obliquely to give the required path of movement to the carriage, for which purpose it is pivoted at one end about a pin 37 in a bracket 24 and has at the other end a pin 39 which extends into a bracket 26 whereby it may be held fast by a lock nut. The frame 28 may be swung round the pivot to a degree controlled by a shaft with one end engaging a screw threaded opening in the .pin 39 and the other having a hand wheel 47. As the conveyer chains 18 move along the trough 11 a timing cam 20 rotates in synchronism with a shaft of the driving sprocket 16 and, when a flight 19 reaches the required position relative to the discharge opening of the mechanism 74, a raised portion 21 on the cam 20 actuates the plunger 22 of a switch Sl 1 which operates to cau s e a motor M2 to rotate a sprocket 83. A chain 94, passing round the sprocket, has mounted on it a roller 96 which projects into a slot 58 in a wall 57 of the carriage 56, resulting in its reciprocation along the length of the support frame 28 until the head of a bolt 99 engages the plunger 97 of a switch S2, causing the motor M2 to stop and bring the carriage 56 to rest. During the forward stroke of the carriage 56 a finger 108 on the bracket of the roller 96 on the chain 94 closes a switch S3 which causes a clutch to engage and transmit drive which actuates the mechanism 74 which forms and cuts the dough and drops it into the cooking cells between the flights 19, this operation being terminated at the right time by the closing of a switch S4 by the finger 107. U.S.A. Specification 2,709,955 is referred to.

Abstract: A lubricating composition comprises an animal, vegetable or synthetic ester lubricating oil and an antioxidant which consists of a minor proportion of both an aromatic amine and a phenol. Animal and vegetable oils mentioned are neatsfoot, sperm, cod liver, menhaden, castor and olive oils.  The synthetic ester lubricating oil may be chosen from diesters of dicarboxylic acids and complex esters such as are produced, for example, by reacting one mol. of a glycol with two mols. of a dicarboxylic acid and two mols. of a monohydric alcohol. The various types of complex esters are discussed, including those containing ether or thioether groups.  Blends of lubricating oils may be employed, such as blends of animal or vegetable oils with synthetic ester oils (e.g. a blend of castor oil with an alkyl ester of an aliphatic monocarboxylic acid) or blends of diesters of dicarboxylic acids with complex esters, but the use of mineral oil is disclaimed.  Examples of suitable amines are p-amino-phenol and its N-lauryl and N-stearyl derivatives, o-phenylene diamine, beta-naphthylamine, N-amyl - p - toluidine, diethyl - alpha - naphthylamine, p - amino - dimethyl aniline, aniline, p-diisopropyl - o - amino - methyl - phenol, phenyl - beta - naphthylamine and phenothiazine.  Aromatic amines having an amide group are also mentioned but the use of anthranilic acid is disclaimed.  The phenol may be chosen from mono-, di- or tri-hydric phenols, substituted phenols (in particular alkyl- and alkoxy-substituted phenols), bis-phenols, n-dodecyl gallate, rufigallol and eugenol.  In examples, lubricating compositions are described consisting of (a) castor oil, isopropyl oleate, 2,6-dibutyl-p-cresol and either phenyl-beta-naphthylamine or phenothiazine; and (b) dinonyl sebacate, a complex ester (derived from polyglycol 300, sebacic acid and 2-ethyl hexanol)), 2,6-di-tert. butyl p-cresol and phenyl-beta-naphthylamine.  For comparison purposes, similar lubricating compositions are described from which either the amine or the phenol has been omitted.  According to the Provisional Specification the lubricating oil may be a mineral oil, a polymerized olefin, a FriedelCrafts adduct or an ether (e.g. a glycol ether or a polyether) while the amine may be aliphatic, alicyclic or heterocyclic.
