Abstract: 373,850. Luggage holders. SOC. ANON. DES USINES CHAUSSON, 35, Rue Malakoff, Asnieres, Seine, France. July 30, 1931, No. 21760. Convention date, Aug. 13, 1930. [Class 103 (ii).] A spare wheel support, which may be mounted on the door of a luggage receptacle, comprises a tilting wheel carrying part jointed at two spaced joints to links or guides so arranged that the spaced joints move in paths such that, near the normal vertical position of the wheel, the centre of gravity of the tiltable parts is so situated relatively to the instantaneous centre of oscillation that the moment due to gravity tends to bring the wheel &c. back into the vertical plane and maintain it there. The wheel support comprises a dummy hub 9 and a pair of spaced arms 5, which may be fixed to the door 7 of a luggage receptacle 8. Each arm 5 is pivoted at 3a, 4a to links 3, 4 pivoted to a plate 2 fixed to a cross member 1 on the car frame, the parts being so arranged that, as the wheels 10, 11 are tilted away from the vertical position, the centre of gravity G of the movable parts first moves upwards along the. locus G. H. J. so that the weight of the parts .tends to move them back to the vertical position. When the position H of unstable equilibrium is reached, the lower ends of curved levers 12, pivoted at 4a to the arms 5, engage a cross member 14, whereby tension springs 13 are progressively stretched as the wheels are lowered. The door 7 may move bodily with the wheel support, or may be hinged at its lower end to the receptacle 8 and be connected by links to the upper ends of the arms 5. In a modification the lower links 4 are replaced by pins mounted on the arms 5 and movable in arcuate slots in the plates 2.

Title: New thiol-sulphoxides, their preparation and use as intermediates
Inventor: AICHENEGG PAUL CONRAD JOSEF
IPC: C07F9/165
Filed: 1957-07-19
Abstract: The invention comprises beta-thiol sulphoxides of the general formula R.SO.CH2CH2SH, wherein R represents an alkyl or aryl group which may be substituted, e.g. by halogen or -CN, the hereinafter described methods of preparing the sulphoxides and a method for converting them into insecticidal thiolo phosphates of the general formula: R.SO.CH2CH2S.P(O)(OR1)(OR2) wherein R is as defined above and R1 and R2 represent alkyl groups. The thiol-sulphoxides are preferably prepared by reacting a mercaptan RSH with ethylene chlorhydrin, if desired in the presence of an alkali, halogenating the remelting hydroxy ethyl sulphide to the corresponding halo ethyl sulphide with, for example, thionyl chloride and thereafter, before or after oxidation to the corresponding sulphoxide, reacting with thiourea and hydrolysing.  Alternatively, the hydroxy ethyl sulphide made as above is converted into the corresponding vinyl sulphide by removal of the elements of water, for example with the aid of solid KOH, the vinyl sulphide is oxidised to the sulphoxide and the latter is then reacted with an alkali metal bisulphide yielding the alkali metal of the desired thiol sulphoxide which is acidified to liberate the free mercaptan.  Finally, the thiol sulphoxides may be prepared by synthesising the halo-ethyl sulphide as above, oxidising the sulphide to the sulphoxide and then reacting with an alkali hydro sulphide, for example alcoholic NaSH.  The oxidation may be effected with H2O2 in acetone or acetic acid.  Examples (1)-(4) describe the preparation by one or other of the above methods using thiourea of ethyl b -thiol ethyl sulphoxide, n-butyl b -thiol ethyl sulphoxide and b -naphthyl b -thiol ethyl sulphoxide and thiol sulphoxides wherein R represents methyl, n-propyl, iso propyl, iso butyl or phenyl may be obtained similarly.  In Example 5, ethyl-b -thiol ethyl sulphoxide is reacted with sodium metal and the resulting sodium mercaptide reacted in benzene with diethyl phosphorochloridate and the thiolo phosphate (R, R1 and R2=ethyl) so formed is isolated and purified by treatment with a mixture of charcoal and kieselguhr.  Reference has been directed by the Comptroller to Specifications 742,769 and 795,860.

Abstract: 951,293. Selsyn machines. BENDIX CORPORATION. June 14, 1962 [June 26, 1961], No. 22956/62. Heading H2A. [Also in Division G1] The transmitting and receiving machines in a Selsyn system are each wound for two poles and twenty-two poles, or separate machines of the different pole-numbers may be used, to provide coarse and fine control and a switching network is provided to switch from one to the other at a predetermined value of two-pole output. The machines (Fig. 1).-The rotor has twentytwo slots accommodating the twenty-two-pole windings 51-72 wound on each tooth and the two-pole windings 31-42 wound in the slots and graded as described in Specification 671,632. The stator has twenty-seven skewed slots carrying the two-pole windings (shown dashed) and the twenty-two-pole windings (shown solid). Both these windings are graded as above. The stator carries two other " phases," not shown. In a modification, Fig. 2 (not shown), the twenty-two-pole stator windings are not wound transversely of the machine but round individual teeth and groups of teeth. The switching network (Fig. 4), comprises pairs of diodes 242, 244 and 248, 250 which conduct above a certain critical voltage. For large errors, the two-pole voltage from rotor winding 218 makes both these sets of diodes conducting, thus energizing the servomotor amplifier 230 via conductor 245, and shunting the output from the twenty-two-pole rotor winding 220 to earth. At low error voltages these diodes block, thus allowing the amplifier to be energized over resistors 246, 252 and conductor 245 to give fine control.

Abstract: 830,028. Automatic character reading. STANDARD TELEPHONES & CABLES Ltd. July 18, 1958 [July 24, 1957], No. 23115/58. Class 106 (1). In character recognition apparatus two or more adjacent areas of the character are studied in succession and compared, an output signal being produced when a change in brightness is detected, such signals accordingly representing the outline of the character. The signals, therefore, depend only upon changes in brightness and not upon the absolute values of character areas and background areas. As shown in Fig. 4, the character image may be superimposed upon a mosaic 3 of photo-cells by an optical system 2. To sense a number of neighbouring areas successively there is provided a taper prism 5 which rotates to move the image of the character in such a way that the area studied by each photo-cell moves in a circle 6. The output from each photo-cell is amplified to produce a signal when a jump is detected from white to black. The signals derived therefore represent the contours of the character. This arrangement is accordingly capable of scanning characters which are black on a white background, white on black, black on grey or grey on white since it responds only to change of signal. Instead of a mosaic of photocells, a line or a single photo-cell may be moved in such a way as to sample the character image in a path having a circular movement. Alternatively the character may be sened with a cathode-ray tube beam which is caused to trace such a path (Fig. 6) by imposing on the staircase scanning voltages of the plates, high-frequency A.C. voltages in 90 degrees phase displacement. In another arrangement, where the character image is sensed by a mosaic of photo-cells, the outputs from adjacent cells are switched in turn to amplifiers which respond to changes of signal.
