Patent GB-824097-A (GB)
Title: New yohimbene derivatives and their preparation
Filed: 1957-11-13
Abstract: The invention comprises D 17-16b -carbo-lower alkoxy-3-epialloyohimbenes, the alkoxy group containing from 1 to 5 carbon atoms, their salts and quaternary compounds, and a process for their preparation by treating the tosylate ester of a 16b -carbo-lower alkoxy-17-acyloxy - 18 - hydroxy - 3 - epialloyohimbane or a salt thereof with a lithium halide in the presence of an organic base, refluxing the resulting halo compound with zinc in acetic acid, and then isolating the product either as the free base or the desired salt.  The acid addition salts may be formed with inorganic or organic acids, e.g. hydrochloric, hydrobromic, hydriodic, sulphuric, phosphoric, nitric, thiocyanic, acetic, oxalic, citric, tartaric, hydroxy ethane sulphonic, or methane sulphonic acid; quaternary derivatives formed with dodecyl chloride are stated to be antiseptics. Treatment of the novel compounds with e.g. sodium methoxide yields the isomeric D 16-compounds, whilst reaction with a peracid, e.g. perbenzoic or monoperphthalic acid, and cleavage of the resulting 17 : 18-epoxide with e.g. sodium methoxide yields a lower alkyl deserpidate which can then be O-acylated giving e.g. deserpidine.  In an example: isoraunescine tosylate in pyridine is refluxed with lithium bromide, the mixture diluted and the resulting precipitated bromo compound crystallized from methanol, refluxed with zinc and acetic acid, giving D 17 - 16b  - carbomethoxy - 3 - epialloyohimbine.  16b  - Carbo - lower - alkoxy - 17 - acyloxy - 18 - tosyloxy - 3 - epialloyohimbanes or salts thereof, in which the acyl group is preferably derived from ethyl carbonic, acetic, acetoacetic, phenyl-acetic, propionic, cyclopentylpropionic, benzoic, 3,4 - methylenedioxybenzoic, carbethoxysyringoic, 3,4,5-trimethoxy-cinnamic, or particularly 3,4,5-trimethoxy-benzoic acid, are prepared by treating lower alkyl 17-O-acylraunescates, particularly isoraunescine, with p-toluene sulphonyl chloride in the presence of a base. Specification 824,098 is referred to.ALSO:Sun screen compositions comprise as active ingredients D 17 - 16b  - carboalkoxy - 3 - epialloyohimbenes, which are preferably incorporated into an hydrophilic ointment containing for example glycols, e.g. propylene glycol, higher aliphatic alcohols, e.g. stearyl alcohol, white petrolatum and distilled water.

Title: Improvements in or relating to variable potentiometers
IPC: H01C10/34
Filed: 1955-12-13
Abstract: 817,483. Variable resistances. METALLUX S.r.L. Dec. 13, 1955 [Dec. 13, 1954], No. 35810/55. Class 37. [Also in Group XL (c)] A variable potentiometer comprises two or more electrically conductive tracks and a movable resilient conductive bridging member which is associated with contacts, one of each of which presses against each track so that on rotation of the movable member the contacts slide along the tracks. Figs. 1 and 2 show a variable resistance element comprising a circular base 1 of insulating material for example steatite, ceramic or vitrous material on which has been deposited by evaporation in vacuum two layers of metal or of a compound of oxides and metals forming tracks 2 and 3. To the outer ends of the tracks are welded terminals 5, 51, 6. A shaft 10 extends through a bush 7 in the support and at one end has an arm 14 of insulating material which is riveted to a resilient conductive bridge element which presses brushes 15, 15<SP>1</SP> against the tracks 2, 3 respectively. The assembly is enclosed by an hermetically sealed cover 4 through which the terminals pass. The outer track 2 is of resistive material and the inner track serves as a collector being of negligible resistance. Alternatively, the inner track 3 may be also of resistance material either or both of the tracks having linear or non-linear resistance characteristics. Thus the potentiometer may serve as a combined volume and tone control in a radio receiver or one or both tracks may be interrupted along the length so as to switch in additional resistance elements as the shaft 10 is rotated to form either a discontinuous resistance or to give a desired law. In a modification, Fig. 3 (not shown), the track 3 is in the form of a closed annulus and acts only as a collector. In a further modification, Fig. 4 (not shown), the inner track 3 has a terminal welded at each end and may act either as a collector or resistive track. There may be one or more main resistive tracks associated with one or more auxiliary or collector tracks.

Abstract: 1,017,400. Windscreen wipers. FORD MOTOR CO. Ltd. Sept. 3, 1964 [Oct. 21, 1963], No. 36064/64. Heading A4F. [Also in Division H2] In a windscreen wiper system in which a wiper blade is operated intermittently for cleaning the windscreen in light rain without smearing, an electric wiper motor 22 is de-energized at the end of each wiping cycle, a capacitor 87 charges and then discharges at a certain voltage to re-energize the motor 22, and re-energization of the motor 22 prevents further charging of the capacitor. In the system illustrated the wiper 26 is operated continuously when conjointly movable switch contacts 43, 47 are engaged with contacts 45, 49 respectively, and intermittant operation is obtained when the switch arms 43, 47 are engaged with terminals 46, 51, respectively. When the terminals 46, 51 are so engaged the capacitor 87 is charged from a battery 10 through a resistor 68 and a variable resistor 85. At a certain voltage the capacitor 87 is discharged by a unijunction transistor 91, and a rectifier 72 is rendered conducting to energize the motor 22 through line 83, contacts 47, 51, and line 57. The motor 22 rotates a cam 32 acting upon a follower 33, which in the parked position of the wiper holds a contact arm 34 in engagement with a contact 38, but on rotation of the motor the cam 32 permits a spring 36 to move the arm 34 into engagement with a contact 37. The motor 22 is then energized through the contacts 34, 37, and the rectifier 72 is extinguished by the earthing of its cathode 73. When the wiper again reaches the parking position the cam 32 disengages the contacts 34, 37 to stop the motor and the capacitor 87 is again charged to repeat the motor starting and stopping sequence.
