Title: Arrangements for regulating the shifting actuators of automatic ally shifted step-gearing
IPC: F16H61/04
Filed: 1972-05-12
Abstract: 1377437 Change-speed gearing control DAIMLER-BENZ AG 12 May 1972 [14 May 1971] 22496/72 Heading F2D To reduce gear shift jerk in automatically shifted stepped gearing, the actuating force of shifting actuators acting on frictional elements is regulated in dependence upon the difference between the actual and prescribed values of the rate of change of engine speed. The prescribed value is varied in relation to operating parameters of the vehicle. As shown, voltages derived from the torque Md, the input rotational speed and the gear-box oil temperature are fed to an amplifier V 2  together with voltages corresponding to the particular gear change and to the vehicle loading, the output signal from the amplifier V 2  constituting the prescribed value for the rate of change of engine speed, and being fed, together with the actual value, into a regulator R. The actuating pressure of the shifting actuator, dependent on torque, temperature and rotational speed is represented by a voltage U 1  and is fed via a switch S 1  to an adding amplifier V 1  with which the control stage S for the pressure regulator is controlled. When an upwards gear shift is started, switches S 1 , S 2  change over, whereby a voltage U 1 /K and the output of the regulator R are connected to the amplifier V 1 . To obtain a gentle transition, nozzles may be fitted in the oil pipe or the control signal may be switched in through a low-pass R.C. unit TP. A rounding-off of the transition at the end of the shift operation can be obtained by reducing the prescribed value towards the end of the operation, Figs. 3-5 (not shown). For all shifting operations, the same switching time may be provided by a timing circuit, Fig. 6 (not shown).

Abstract: 1,091,662. Automatic brake adjuster. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. May 5, 1965 [June 1, 1964], No. 22583/64. Heading F2E. An automatic slack adjuster comprises an element movable in an endless path in steps and being so stepped during each brake operation when the brake slack is greater than a predetermined value, the element passing through a predetermined position in that path to actuate mechanism to effect reduction of slack. The adjuster comprises an arm 2 connected to brake operating linkage (not shown) and connected through a worm 5 and worm-wheel 3 to a splined brake-actuating cam-shaft. The worm-shaft 7 is rotatable, to take up brake clearance, through the clutch 9, 21 by a gear sector 27 pivoted by a cam (30, Fig. 2, not shown), deflected by the passage of an element (33) on a ratchet-wheel moved in steps when brake clearance is excessive by the relative motion between the housing 1 and a lever 42 connected with lost motion to the stationary structure. Motion of the gear sector causes clutch member 21 to rotate, riding over the teeth of member 9 and stressing spring 25, the latter returning the member 21 on brake release, as the worm and worm-wheel unlock, to rotate member 9 and the worm to take up slack. Members 9 and 21 may be separated by pulling on cover 17 to overcome spring 11. The worm-shaft 7 may then be rotated manually to adjust the clearance. In a second embodiment (Figs. 5-7, not shown) the element 33 on the ratchet wheel rocks a lever 50 which engages a further lever (53) connected directly to clutch member 21. In a third embodiment (Figs. 8, 9, not shown) the ratchet is operated on the application stroke of the brake by a lever having two pawls, the ratchet carrying a cam which lifts a rack member (127) engaging a sector on the clutch member 21.

Title: 1, 3-diazacycloalkane compounds
IPC: C07D233/42
Filed: 1956-07-23
Abstract: The invention comprises 1-(dialkylaminoalkyl) - 1,3 - diazacycloalkane - 2 - thiones corresponding to the general formula <FORM:0797714/IV (b)/1> wherein R stands for a straight or branched chain alkyl radical having from 1 to 8 carbon atoms, and n and m each stand for the integers 2 or 3, and their acid salts.  The novel compounds may be prepared by reacting a polyamine of the formula NH2(CH2)nNH(CH2)mNR2 with carbon disulphide in the presence of an inert solvent, preferably at 0-135 DEG  C., separating the reaction product formed, e.g. by filtration, and heating it to obtain the desired product. Suitable solvents for the first step are alcohols, e.g. ethanol, propanol, and butanol; hydrocarbons, e.g. petroleum ether, kerosine and benzene; or ethers such as ethyl ether and propyl ether.  The solid addition product, which is considered to be an internal salt of a dithiocarbamic acid, may be cyclized by heating in the dry state, or by refluxing in the presence of an inert solvent such as benzene or toluene, until hydrogen sulphide evolution ceases. The new compounds are useful as rodenticides and as intermediates for the synthesis of biologically active compounds.  In examples: (1) 1-dimethyl-amino-5-amino-3-azapentane in ethanol is added portionwise to an ethanol solution of carbon disulphide, the addition product separates as an oily layer and, after distilling off the ethanol, the residue is heated at 150 DEG  C. to give 1 - (b  - dimethylaminoethyl) - 1,3 - diazacyclopentane - 2 - thione; similarly 1-(a -dimethylaminopropyl)-1,3-diazacyclohexane-2-thione is obtained from 1-dimethylamino-7-amino-4-azaheptane; (2) 1 - (b  - diethylaminoethyl) - 1,3 - diazacyclopentane-2-thione is obtained from 1-diethylamino-5-amino-3-azapentane; the product is dissolved in methanol containing hydriodic acid and the hydriodide salt is precipitated by addition of ether; 1-(g -diethylaminopropyl)-1,3-diazacyclohexane-2-thione is obtained from 1 - diethylamino - 7 - amino - 4 - azaheptane; (3) 1 - (b  - di - n - propyl - aminoethyl) - 1,3 - diazacyclopentane-2-thione is obtained from 1-di-n-propylamino-5-amino-3-azapentane and is converted to the hydroiodide salt; similarly 1-di - n - propylamino - 7 - amino - 4 - azaheptane is converted to 1-(a -di-n-propylaminopropyl)-1,3-diazacyclohexane-2-thione; (4) 1-(b -di-n-butylaminoethyl) - 1,3 - diazacyclopentane - 2 - thione is obtained from 1-di-n-butylamino-5-amino-3-azapentane; similarly 1-(a -di-n-butylaminopropyl)-1,3-diazacyclohexane-2-thione is obtained from 1-di-n-butylamino-7-amino-4-azaheptane.  The products are converted into their picrates in conventional manner.

Abstract: 1512405 Beam scanning device BOFORS AB 23 May 1975 22950/75 Heading G2J [Also in Division F3] A device for scanning an optical beam through a sector in a substantially fixed plane (eg for missile tracking applications) comprises a source of a narrow beam 10, a disc 1 having planar but non- parallel sides 2, 3, and a reflector 12 having two reflecting surfaces 12a, 12b at right angles and intersecting at an edge (either notional or real) 12c. The disc rotates about axis 6 and as shown in the crosssection of Fig. 1 the emergent beam is always substantially parallel to the axis 6 (due to the retroflective properties of the reflector 12 in conjunction with the very small difference in optical thickness of the disc 1 for beams 11, 11'). When viewed in plan, however (Fig.2b) the reflector 12 behaves as a plane mirror and the beam 11' is deflected according to the rotational position of the disc 1. As shown in Fig.3 (not shown) two beams may be caused to scan in mutually perpendicular directions by suitable arrangement of the respective source and reflector for each beam relative to the disc. A single source may be beam-split to provide two scanning beams which are recombined on a common optic axis as shown in Fig.4 (not shown).
