Title: Improvements in rheostats and other electric circuit controllers
IPC: H02P1/08
Filed: 1921-07-20
Abstract: 178,771. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). July 20, 1921. Controllers, actuating mechanism for, electromagnetic.-In power-operated resistance or other multiple contact switches, exact positioning of a travelling contact upon the stationary contacts is ensured, whenever it is brought to rest, by positive locks operated by electromagnets the circuits of which are controlled by auxiliary switches moving independently of the manual control. The apparatus is shown diagrammatically in Fig. 1. A contact 3 travelling over rows of resistance studs 1, 2 is carried up and down a screwed shaft rotated by a pilot motor 5 which is started by closing one of a pair of reversing switches 9, 10 by means of electromagnets 9<a>, 10<a>, and push buttons 11, 13. The act of closing either switch frees one of a pair of locking pawls 23, 24 from engagement with ratchet stops on a disc 20 and allows the vertical shaft to rotate. When the operator opens the push-button at any desired stage, current continues to reach the motor through one of a pair of revolving contact rings 32, 33 and corresponding brushes, until a gap in the ring comes on the brushes, whereupon the magnet of the reversing switch is cut out and the pawl drops into locking engagement. The parts are so dimensioned that the stoppage of the ver. tical shaft in a definite angular position leaves the travelling contact exactly on a stud. A slip ping-clutch drive 8 allows the motor to run on and come to rest under friction. Up and down limit switches and a push button 16 for determining one complete travel are provided. Additional vertical rows of contact studs and corresponding additional travelling contacts control a motor field circuit.

Title: Cathode ray tubes for colour television
Inventor: FAIRHURST HAROLD ALFRED
IPC: H04N9/24
Filed: 1960-06-03
Abstract: 992,626. Colour television receivers. RANKBUSH-MURPHY Ltd. July 10, 1961 [June 3, 1960], No. 19800/60. Heading H4F. [Also in Division H1] Colour television signals are reproduced by a cathode-ray tube 10, Fig. 1, having a screen formed of phosphor dots arranged as shown in Fig. 2 and of such a size that the cathode-ray spot can extend to each of three dots to produce white light, for example as shown at 28<SP>1</SP>, or can cover one dot alone to produce a pure hue, for example as shown at 28<SP>11</SP>. The cathode ray is made to traverse its horizontal scan in steps with intervening pauses by means of a sawtooth or sinusoidal arresting signal 18A applied to auxiliary plates or coils 18, 19 and during each period of dwell the ray is steered to a position in which it excites three phosphor dots in the correct proportions indicated by a chrominance signal. For this purpose the tube is provided with an auxiliary triangular assembly 20, 21, 22 of deflecting plates and three photo-electric cells 24, 25, 26 with associated filters 34, 35, 36 respectively transmissive of red, green and blue light. The photo-electric cell signals are compared with red, green and blue signals each in a separate comparator, for example 38, and the resulting signals applied through .amplifiers 40 to control plates 20, 21, 22. A luminance signal is applied to the tube intensity modulation electrode. The luminance and chrominance signals may be an N.T.S.C. signal. A blanking signal 30A may be employed to eliminate the horizontal trace between periods of dwell and to reduce the intensity during the period of steering to achieve the desired colour reproduction. The chrominance signal is cut off when the cathode ray is suppressed to avoid the production of spurious steering signals. The frequency of the arresting signal is determined by the desired horizontal resolution. With an N.T S C signal, a frequency twice that of the subcarrier frequency is suggested Photoelectric cells 24, 25, 26 are disposed at the junction of the neck and bulb of the tube 10; to permit light from the phosphors to reach them the usual aluminizing is made not very dense. A dense neutral filter is then included in front of the tube screen to prevent ambient light reaching the cells. Alternatively, the phosphors may be arranged to produce, in addition to red, green and blue light, each a different range of ultra-violet light to which the cells are made responsive. Specification 780,814 is referred to.

Title: Improvements in or relating to preparations containing benzoxathiol derivatives for the care of hair and skin
IPC: C07D411/12
Filed: 1956-07-02
Abstract: There are claimed as novel compounds benzoxathiols of the formula <FORM:0823251/IV (a)/1> in which R1 is an aryl or aralkyl group, an acyl group, an aryloxy or aralkoxy group, an -O-acyl or -S- acyl group, a hydrosulphide or sulphonyl group or salt thereof; R2 is a carboxyl or carboxylic ester group, an alkoxy group, an alkyl group with from 1 to 6 carbon atoms, an acyl group, a nitro- or amino-group or a sulphonyl group or a salt thereof; X is oxygen, sulphur or an imino group.  There are also mentioned compounds of the above formula in which R1 is additionally hydrogen, hydroxyl, C1-5 alkyl, C1-5 alkoxy or acyl and R2 is addi tionally hydrogen, hydroxyl or halogen. They may be prepared by the following methods.  The appropriate substituted hydroxy or thiohydroxy benzene is rhodanized by the action of an alkali rhodanide in methanol, saturated with sodium bromide and treatment with bromine or by the action of copper sulphate and ammonium rhodanide in aqueous solution.  The rhodanide first formed is rearranged in the course of the reaction to a 2-imino-benzoxathiol.  The latter when treated with dilute acid gives rise to the corresponding 2-oxo-benzoxathiol.  The benzoxathiols may also be obtained by the action of phosgene on the corresponding o-hydroxy thiophenols in the presence of pyridine and an inert solvent.  Alternatively, benzoxathiol compounds themselves may be converted to benzoxathiol compounds of the above formul  by standard methods of which examples are given.ALSO:Compositions useful for shedding dead skin lamell  from the scalp and in other skin infections comprise as the active ingredient a substance of the formula <FORM:0823251/VI/1> where R1 is hydrogen, a hydroxyl group, an alkyl or alkoxy group having 1 to 5 carbon atoms, an aryl or aryloxy group, an aralkyl or aralkyloxy group, an acyl, -O-acyl, or -S-acyl group, a hydrosulphide group or a sulphonyl group or salt thereof: R2 is hydrogen, a hydroxyl group, a halogen atom, a carboxyl or esterified carboxyl group, an alkyl group of 1 to 6 carbon atoms, an acyl or alkyloxy group, a nitro group, an amino group or a sulphonyl group or salt thereof: X is a divalent atom or group. These compounds are in admixture with a suitable carrier which may be liquid or solid, or gel or gel-like.  If liquid it may contain perfumes, wetting or dispersing agents, e.g. neutral alkylaryl sulphonate, preservatives, deodorants and solid insoluble carriers. The compositions which may be in the form of solutions, based on water, ethyl alcohol, oleyl alcohol, glycerol, cetyl alcohol, octadecyl alcohol or sorbital; emulsions; hair washing preparations, or powders contain the active ingredient in the range of 1-5% by weight.
