Title: Car retarder speed control apparatus
IPC: B61K7/12
Filed: 1956-06-27
Abstract: 799,249. Railway retarders. WESTING- HOUSE AIR BRAKE CO. June 27, 1956 [July 11, 1955], No..19890/56. Class 103 (1). In retarder systems for railway hump classification yards, it is usual for a predetermined initial pressure to be applied to the retarder bars before a, car enters the retarder, and then to reduce the initial pressure to a partial pressure as the speed of the car unit within the retarder is lowered to near the correct or desired leaving speed, the retarder bar pressure being completely released should the car's speed be reduced to the correct speed. The retarder bars, therefore, have to be moved from a closed to an open position, if a car should enter them, which is already moving at less than the required leaving speed and the invention aims at avoiding the pressure expended and the unnecessary wear of the retarder shoes in this operation. If a car should enter the retarder CR at less than the desired leaving speed of, for example 5 miles per hour, shunting of track relay 1T will set in operation, the relay counting chains, the time measuring means being permitted to operate to its limit so that the relays 4U and 6M are energized. The control relays 2PPR and 2SPR will be energized through the network since the increased speed of the car unit in section 1S is less than the selected leaving speed. The normal contact 140 for relay 2PPR will be closed to connect wire 160 to the terminal 138 of the network SP. The control circuits are thus conditioned to apply a positive voltage to the car retarder terminal XP should the control relay A be energized. When the leading wheels of the slow-moving car unit enter section 2S of the car retarder, the energization of control relay A merely transfers the positive energy supply to terminal XP from its back contact 168 and wire 169 to its front contact 159 and wire 160 to terminal XP so that the car retarder remains open as the car unit proceeds through the retarder. The operation of the control system as a whole is generally similar to that described in Specification 724,844 but an occupancy relay RR1 is provided which is energized only so long as a car is in the retarder and which through control relay A makes the retarder inoperative if no car is passing through.

Title: Process for the production of unsaturated fatty alcohols
Inventor: STICKDORN KURT
IPC: C07C33/025
Filed: 1964-05-13
Abstract: Unsaturated fatty alcohols are obtained by the continuous hydrogenation of esters of unsaturated fatty acids in the presence of a catalyst consisting of the carbonates, hydroxides and/or oxides in amounts corresponding to 2-6 parts by weight of cadmium and 1.5-8 parts by weight of zinc, manganese or a combination thereof, to one part by weight of copper, the catalyst being reduced, e.g. with hydrogen, before the alcohol production.  An example reduces sunflower oil fatty acid butyl ester.

Copolymers of 1-olefines, optionally including multiolefines, are made by polymerizing the monomers in the presence of a catalyst comprising (a) organometallic compounds or metal hydride of elements of Groups I A , IIB or III B  of the Periodic System according to Mendeleeff, and (b) compounds of Groups IV A , V A , VI A  or VIII of the Periodic System, and in the presence of activating compounds of the formula R-SO 2 X, R-SO-X, R-S-X or S n X 2  (in which R denotes an unchlorinated or chlorinated alkyl, cycloalkyl, or aryl or halogen, X denotes halogen and n is 1 or 2), or esters of halogenated carboxylic acids, unsaturated halogenated cycloaliphatics, and also azo compounds wherein the activating compounds are added in one or more batches after the catalyst has been at least partly used up. The polymerizing solution may be cooled prior to each addition of activating compound. The 1-olefm may be ethylene, propylene, butene-(1), pentene-(1), hexene-(1), decene-(1) and 4-methylpentene- (1). The multiolefine may be selected from non- conjugated dienes, trivinyl cyclohexane, dicyclopentadiene, alkenylnorbornenes, norbornenedienes, cyclodienes, cyclotrienes, mono- and disubstituted alkylcyclooctadienes-1,5, and cyclododecatrienes.

Abstract: 1392366 Cinematography EASTMAN KODAK CO 1 May 1972 [3 May 1971] 20038/72 Addition to 1300976 Heading G2E An improvement to the projector of Specification 1300976 is the provision of means to hold operating lever 57 in its operative position until the latching device (tabs 100a, 102a) is engaged to hold the stripping mechanism in its active position. This means comprises cam 104a contacting a surface of cam 61'. The cam shaft 34 starts to rotate on depression of lever 57 and thus the lever 57 is kept depressed by the cam 104a. However the cam 104a is shaped so that after tabs 100a, 102a engage, Fig.4, the cam 104a no longer depresses cam 61'. This facilitates subsequent de-activation of the stripping mechanism by a tension sensor.

The propeller is arranged at a distance approximately equal to its diameter below the cone, and is carried on a shaft mounted in ball bearings and driven at variable speed either electrically or through a gearbox. In conjunction with the agitator are provided a gauge vessel y, and tanks b<1>, d<1> in which milk of lime is kept in constant agitation. Raw juice, controlled by a valve a, and a quantity of lime from the tank bl for initial defecation are mixed by an ejector z and fed into the gauge vessel until the latter is full, when the mixture is admitted by the valve b into the gauge vessel until the latter is full, when the mixture is admitted by the valve b into the vessel a. The propeller is rotated first at low speed and then, simultaneously, its speed is increased and the pump d is started to inject further lime into the vessel a from tank d<1>, and sulphur dioxide or like ingredient is admitted under pressure through a valve e. After treatment, emptying is effected through a valve c with the propeller rotating at low speed. The tanks bl, d<1> have adjustable overflows and conjugated control means for feeding the ingredients.

To enter the operating position a release arm 34 pivoted at 36 is swung towards shaft 21, a pin 37 on the arm 34 engaging a ramp 41 on spring 40 to remove the latter from the arm 23, spring 31 then urging the latter towards the drive wheel 3. When the bobbin is wound the rising level of thread thereon abuts a sensing member 32 pivoted to arm 34 to swing the latter back, the released spring 40 engaging arm 23 to overcome spring 31 and move the winder to its release position. The pivoted arms 23, 34 may be replaced by rectilinearly moving slides.

[Class 60] In a centreless grinder the backing wheel 1 and a motor 5 driving it are both mounted on a plate or like member 2 which is angularly adjustable about an axis 11 at rightangles to the axis of the wheel 1 so that the latter may be set at the desired angle to effect the axial feed of the work. The arrangement avoids the use of wheel and chain transmissions between the motor and regulating wheel, which result in back-lash and irregular grinding. In the construction shown, the regulating wheel and motor are carried on reverse sides of the member 2, the drive being effected through worm and spur gearing, and the axis 11 about which the plate member 2 is angularly adjustable passes centrally through the regulating wheel. The adjustment is effected by a screw 13 bearing on a pin 14 secured in the member 2.
