Abstract: 498,551. Windscreen-cleaners. TRICO PRODUCTS CORPORATION, and HORTON, E. C. Dec. 2, 1937, No. 33409. [Class 138 (i)] The blade of a windscreen-wiper is connected to the wiper arm by an attachment device so formed as to allow relative rocking between the device and blade as the wiper is oscillated, this rocking acting to press the blade against the screen. The resilient blade 9 is mounted in a metal carrier which has a cylindrical portion 6 to receive a head 11 on the blade and marginal portions 8 to limit flexing of the blade. The attaching device consists of a clip 14 with straps 15 which conform to the contour of, and embrace, the part 6 of the carrier, so that the latter is free to rotate in the straps. The free ends of the latter project through apertures 16 in the portions 8, so that they engage the blade 9 and press it against the windscreen as the carrier rotates in the straps during successive strokes of the wiper. The degree to which the ears project through the openings is limited by shoulders 18, and the openings 16 may be offset. The device 14 is adapted for connection to various forms of wiper arm 3. As shown, the arm has a slot to receive a fin 19 on the device. An opening 20 allows connection by means of a bolt, and for the hooked type of arm, the device has spaced walls 21 and abutments 22 which co-operate with a shoulder 23 of the fin to provide an opening 24 to receive the hook.

Title: Slip-preventing means for locomotives having individual axle drives
IPC: B61C15/12
Filed: 1938-11-22
Abstract: 521,608. Locomotives; engine controlling means. SCHMIDTSCHE HEISSDAMPFGES. Nov. 22, 1938, No. 33977. Convention date, Dec. 3, 1937. [Classes 79 (i) and 79 (v)] In slip-preventing means for locomotives having axles 1 driven by individual engines 2 controlled by hydraulic means, each driving axle and one non-driving axle 18 drives an oil pump 4 or 19, the oil pressure produced by the non-driving axle pumps 19 serving as a standard for the hydraulic control of the engines, this oil pressure acting on one side of the piston 8 of a control device 5 for each engine, and the oil pressure produced by 'the driving-axle pump acting on the other side of the piston, movement of any piston caused by racing.of its. axle causing the corresponding engine to be slowed down. In the construction shown the engines 2 are supplied with steam from a pipe 45 through pipes 3 and throttles 40 controlled by the pistons 8 of the control devices 5. Each pump 4 is connected by its suction pipe 12 to a common tank 10 and by a pressure pipe 6 to the upper part 7 of its device 5 above the piston 8. Oil can flow from the spaces 7 through adjustable valves 15 and pipes 9 back to the tank 10. The non-driving axle pump 19 is connected by its suction pipe 21 to the tank 10 and by its. delivery pipe 22 to a control box 20 having a pressure chamber 24 and a relief chamber 23 communicating through an overload-release valve 30 and an adjustable valve 27, the chamber 23 being connected by a pipe 21<SP>1</SP> to the tank 10. From the pressure chamber 24 a pipe 32 leads to the lower part 33 of each of the control devices 5. Springs 44 tend to move each throttle 40 to the open position as shown. When steam is admitted to the engines and the locomotive begins to move, the oil pressure from the non-driving axle pump acts on the underside of each piston 8 while the pressure from each driving-axle pump acts on the upper side. If one of the driving axles races, due to wheel slip, the resulting increase in the oil pressure in the corresponding space 7 forces the piston 8 down and closes that throttle until the racing axle rotates at the same speed as the non-driving axle. When the locomotive has reached a pre-determined speed, say, 30- 40 kms. per hour, the automatic throttle control is automatically put out of action. For this purpose the oil pipe 32 is connected by pipes 35 to valve chambers in the upper parts of the devices 5, the increased oil pressure at the higher locomotive speeds being arranged to force back spring-loaded valves and open bypasses connecting the cylinder spaces 7 to the return pipes 9 so that oil pressure cannot build up in the spaces 7 to close the throttles even if the engines race.

Title: Improved extractive distillation operation for preparation of catalytic cracking feed stocks
IPC: C10G21/00
Filed: 1955-11-29
Abstract: <PICT:0782791/III/1> Petroleum oils which contain metallic contaminants, particularly nickel compounds, are purified by subjecting the oil to distillation or coking and bringing the vapours into intimate contact with a counter-current flow of asphaltic oil having an initial boiling-point above 1050 DEG  F., whereby the metallic contaminants are extracted by the asphaltic oil, and a metal-free gas oil, suitable for catalytic cracking, is obtained as distillate.  Heavy virgin stocks obtained by solvent precipitation from petroleum having a low content of metallic contaminants may in some cases be used as refluxing agent; thermal tars separated from the products of a thermal cracking unit may also be used; but "synthetic asphalts" separated from the products of a cat. cracking process are the preferred agents.  A residual oil is introduced through line 46 into coker 45, which may contain a fluidized bed of coke particles at temperatures of 800 DEG  to 1000 DEG  F.  The vapours produced in the coker are introduced into tower 48 where they are scrubbed with heavy catalytic tar, introduced through line 57. The vapours withdrawn from the head of the scrubbing tower are subjected to catalytic cracking in reactor 50. The cracked products are fractionated in vacuum distillation tower 52; and light-boiling products are withdrawn through lines 53, 54, 55 and 56.  Heavy catalytic tar is withdrawn from the base of tower 52, and is conveyed to scrubbing tower 48 via line 57. The heavy liquid withdrawn from the base of tower 48 is passed to coker 45.

Title: A gear-shaping machine of the kind having a pinion as the cutting tool
Inventor: CARR HERBERT
IPC: B23F23/12
Filed: 1959-10-08
Abstract: 891,506. Gear-cutting. DRUMMOND BROS. Ltd. Nov. 8, 1960 [Oct. 8, 1959], No. 34148/59. Class 83 (3). A gear-shaping machine comprises a feed cam 1, Fig. 1A, for relatively feeding a workcarrier and a tool-carrier such that there is a dwell 6 at maximum feed depth for one revolution of the work, and means for sharply separating the carriers as soon as the said revolution has been completed. In conventional machines, the tool-carrying slide is fed by a weight under the constraint of the feed-cam engaging a roller 3 on the slide. To separate the carriers, the feed-cam is given a sudden acceleration when cutting is complete to allow the roller to drop into a recess 7 in the cam. To relieve the work on the up-stroke of the cutter, a shaft 14, Fig. 2, is oscillated by a cam 11 mounted on a main drive shaft 10 and acting through a rod 13 and a bell-crank 15, the cam and roller being held in contact by a spring 17 acting through a rod 16. In the machine of the invention, a disc 37, Fig. 3, having a recess 38 is mounted on the same shaft 2 as the feed-cam. A sharp projection 36 is held against the disc by a weight or a spring 39. At the instant when the gear is finished, the projection 36 drops into the recess 38 and linkage 33, 30, 29, 26 releases a clutch 23, thus causing the work relief mechanism 13, 15 to be ineffective. However, the block 26 is splined to the work-relief shaft 14 and a spring 17A acting on the block either holds the work-relief shaft in its work-withdrawn position or rotates it to that position if the cutter is on a down-stroke. In a modification, the mechanism 33, 36 is omitted and the block 26 is moved by a pneumatic piston operated by a switch actuated by the disc 37. Specification 891,507 is referred to.

Abstract: 1514918 Wired broadcasting systems COMMUNICATIONS PATENTS Ltd 25 July 1975 [6 Aug 1974] 34513/74 Heading H4R Programmes for which a charge is levied are transmitted to subscriber units accompanied by a pay signal, in response to which the subscriber may operate a selection device to accept the programme. Subsequently a signal indicative of the acceptance of a programme is transmitted to the exchange. At the end of a programme the subscriber units are interrogated using the arrangement disclosed in Specification 1,510,117 in which each subscriber unit is allotted a respective interrogation signal. Chargeable programmes are transmitted on wires 5 accompanied by a 12 MHz pay signal which causes circuit 19 to produce an ouput on wire 20 which is inverted by gate 21 to provide an "0" input to gate 7. When selector switch 2 is in the position shown in which it couples the television set via gate 4 to wires 5, a small 30 Hz potential, supplied from an exchange over wires 5 for power purposes, appears across resistor 11 and causes the potential on wire 16 via components 12-15 to go to logic 0 after a predetermined delay which allows a free sample viewing period of the pay programme. OR gate 7 will then apply a logic 0 to inhibit the gate 4 which prevents further viewing of the programme until button 18 is depressed, to cause AND gate 25 to provide a logic 1 signal to OR gate 7. If it is desired to inhibit a subscriber unit from selecting a pay programme, e.g. due to non- payment of bills, the particular subscribers interrogation signal is sent accompanied by both the 12 MHz pay signal and the reply tone, cf Specification 1,510,117, to enable AND gate 22 to disable gate 25. To prevent a subscriber from obtaining a repetitive sequence of free samples of a programme, the diode 14 is arranged to provide the input to amplifier 15 with a very long discharge time, e.g. 10-15 mins.
