Title: Improvements in or relating to electric oscillation generators
IPC: H03B5/10
Filed: 1937-07-27
Abstract: 501,448. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 27, 1937, No.20738. Convention date, July 27, 1936. [Class 40 (v)] A reciprooally-coupled valve circuit of the multi-vibrator type for generating electric impulses, has an oscillatory circuit associated with one or both grids coupled to an inductance coil in an anode circuit of the opposite valve of the pair. In the form shown in Fig. 1, a coil 12 in the anode circuit of one valve 10 of the multi-vibrator pair 10, 11 is coupled to a tuned circuit 19, 20 connected to the grid of the other valve 11. When current starts to flow in the valve 10, the grid of valve 11 is driven negative by the voltage pulse applied through the coupling-condenser 21, and a negative halfcycle of the oscillation set up in the circuit 19, 20 also renders the grid negative. The joint effect is to render the time during which the valve 11 is blocked independent of variations in the supply voltage. A resistance-capacity unit 15 may be connected to the grid of the valve 10 with the object of rendering the impulses of rectangular form, as described in Specification 501,046. The grid of the valve 11 is given a positive bias by connection to a point P on the battery 24. In a modification, Fig. 5 (not shown), tuned circuits such as 19, 20 are associated with each grid, and are coupled to coils such as 12 in the anode circuits of the opposite valves. The inter-valve coupling connection may be made to the anodes of both valves, as indicated by the dotted line 25, Fig. 1. Specification 456,840 is referred to. In the Specification as open to inspection under Sect. 91, a modification is referred to in which screen-grid valves are used with the normal reciprocal coupling by resistanoes and capacities, the period of the oscillation being thereby rendered independent of supply voltage variations. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to optical oscillographs
IPC: G01D15/14
Filed: 1952-08-20
Abstract: 712,573. Recording-apparatus. NATIONAL RESEARCH COUNCIL. Aug. 20, 1952 [Sept. 4, 1951], No. 20898/52. Class 106 (4) An optical oscillograph comprises a light source, a light-reflective mirror-motor positioned to receive light rays directly from the source along a given axis and to reflect an image of the source on a record surface and means positioned on the opposite side of the light source from the mirror-motor forming a second source of light projecting light rays onto the mirror-motor along an axis displaced with respect to the given axis, whereby spaced images of the sources are reflected from the mirror-motor onto the surface ; where a mirror-motor is defined as a mirror and a motor (e.g. a galvanometer, a pressure capsule, an electric motor, a pendulum or a bimetallic strip) for rotating the mirror in response to a variable. As applied to a multi-channel optical oscillograph which may record several variables simultaneously on a moving photographic film, each variable is transformed into a light trace by a mirror-motor, while a fixed mirror, after reflection losses, reflects an image of the light source on each mirror-motor which thus produces a second but fainter light trace, character istically displaced from the main trace to form a means of identification. As shown, Figs. 1, 2, the optical system of the apparatus comprises a lamp 10 with a linear filament 22 mounted within a non-reflecting light shield 11 having front and rear apertures 23. 24 the latter having a plane mirror 12 held against it by a spring clip 26, a series of mirror-motors shown as reflecting galvanometers 13<SP>1</SP>-13<SP>6</SP> mounted in a straight line in a magnet block 21 and a light mask 14 having a slit 15 parallel to the line of galvanometers and perpendicular to the lamp filament 22. Photographic film 16 passes from a supply roller 17 to a take up roller 19 between a drive roller 18 and pressure rollers 20 and light rays passing through the slit 15 cause main traces 13<SP>1</SP> 3  to 13<SP>6</SP> 3  and "ghost" traces 13<SP>1</SP> 4  to 13<SP>6</SP> 4  respectively to be recorded according to whether the rays pass direct from the lamp to the galvanometer mirrors or indirectly after reflection from the mirrors 12 with consequent loss of light intensity. According to the disposition of the galvanometer on one side or the other of the optical axis of the system the ghost trace will be one side or the other of the main trace and its distance therefrom will depend upon the distance of the galvanometer from the axis so that each trace may be identified from the relative position of its ghost trace. The mirror-motors need not be disposed in a straight line and there may be more than one light source 10 each with a corresponding mirror 12 so long as each ghost trace is uniquely disposed with respect to its main trace which may be facilitated in the case of more than one light source by varying the distances of the mirrors therefrom. A filter may be used in front of the mirrors to provide a desired amount of reflection losses.

Title: Optically active 3-mercapto-phenthiazine derivatives
IPC: C07D417/06
Filed: 1958-06-30
Abstract: The invention comprises optically active forms of compounds of the general formula <FORM:0873316/IV (b)/1> (wherein R1 represents a hydrogen atom or a C1-C5 alkyl group and R2 a hydrogen atom or a C1-C4 alkyl group, and wherein the asymmetric carbon atom is marked +) and certain of their acid addition salts, and the preparation thereof by resolving the corresponding racemic compounds with the aid of optically active acids, or (when neither R1 nor R2 represents a hydrogen atom) by reacting a phenthiazine of the general formula <FORM:0873316/IV (b)/2> (wherein R11 represents a C1-C5 alky group) with an optically active piperidine derivative of the general formula <FORM:0873316/IV (b)/3> (wherein R12 represents a C1-C4 alky group). The products are useful as spasmolytic, histaminolytic, sympathicolytic, adrenolytic and sedative agents and as potentiators of anaesthetics, the (+)-isomers being stronger but the (-)-isomers more specific in their action.  Optically active piperidine halides of the third general formula above are prepared by the action of halogenating agents on the corresponding optically active piperidine alcohols obtained by resolution of the racemic forms thereof. Specifications 863,547 and 863,551 also are referred to.
Patent GB-600853-A (GB)
Title: Improvements in and relating to transducers for radiating and/or receiving vibrational energy
IPC: G10K11/34
Filed: 1945-08-14
Abstract: 600,853. Diaphragms. BRUSH DEVELOPMENT CO. Aug. 14, 1945, No. 20952. Convention date, June 2, 1944. [Class 40 (iv)] [Also in Group XL (c)] In an electro-acoustic transmitter or receiver for use in air or a liquid medium, different regions of the radiating or receiving surface have different amplitudes and areas, so that the maximum effect may be along the axis. Thus, a circular diaphragm 13, Fig. 2, may be surrounded by an annular diaphragm 14, their amplitudes being in the ratio 2.4 : 1 and their radii in the ratio 0.607: 1, so as to minimize the side lobes of the polar response pattern. Alternatively, Fig. 4 (not shown), there may be three circular zones, and the Specification shows how to calculate the requisite areas and amplitudes. In a loud-speaker which approximates to these conditions, Fig. 7, the radiating surface is formed by piezoelectric crystals of the expander type, made of Rochelle salt, primary ammonium phosphate, or the like and energized along the electric axis (which is transverse in Fig. 7 so that the crystals expand in a direction normal to the plane of the Figure). The difference of amplitude may be obtained by applying the same voltage to all the crystals, but making the crystals in the inner zone 45 thinner between the electrodes than those in the outer ?,one 46, so that they have a larger voltage - gradient. Alternatively, different voltages may be applied to crystals of equal size, Fig. 5 (not shown), the difference being produced by series-parallel grouping, Fig. 12 (not shown), or by the use of different amplifiers, or the crystals may differ in length, Fig. 6 (not shown). The crystals are mounted on a heavy glass base 41, Fig. 8, so that wide margins around the electrodes are unnecessary, and sound-proof pads 40, 39, of rubber-impregnated cork, corprene or the like, are provided inside and outside the housing 35. The crystals are separated by corprene or the like, as described in Specifications 600,248 and 600,300, and may be mounted in strips, adjacent crystals having opposite polarities ; they are ground flat as an assembly. A rubber cover 38 is provided, and the housing is filled with glycerine through the opening 49. In another embodiment, Figs. 9, 10, 11 (not shown), the vibrating surface and its zones are rectangular instead of approximately circular. The directional radiation pattern may be varied by variously connecting eight such zones, and the housing may contain an amplifier.

Title: Improvements in photoelectric meters
IPC: G01J5/60
Filed: 1949-08-12
Abstract: 665,942. Photo-electric photometers. THOMSON, C. L. Aug. 14, 1950 [Aug. 12, 1949], No. 21005/49. Class 40 (iii). A combined meter for determining quality and intensity of visible or non-visible radiation comprises at least two filters of substantially differing wavelengths, a photo-cell or cell area associated with each and a switch for switching the output of either or both said cells to a galvanometer. As shown, radiation is received on a sloping light diffusing screen 5, behind which are situated a pair of filters 6, 7, one responsive to red or red-orange light and the other to blue or blue-green. These filters may be of dyed gelatine and a proportion of white light may be allowed to pass by perforating them. Each filter has associated with it an area 8, 9 of a divided photo-cell 10, the positive pole of which is connected direct to a galvanometer. In the first position of the switch (as shown) cell-area 8 only feeds the galvanometer via potentiometer 15, in the second position cell-area 9 only. In the third and fourth positions the cell outputs are paralleled to the galvanometer but a different one of shunting resistances 17, 18 is connected across the cell in each case. In measuring colour temperature the switch 14 is set to the first position and potentiometer 15 adjusted to bring the instrument pointer 3 to a fixed mark; the switch is then set to the second position when colour temperature may be read directly. To investigate discontinuous spectra more filters and switch positions may be provided. The filters themselves may be light-diffusing eliminating screen 5. Thus red and blue etched glass elements may be cemented edge-to-edge, or dyed opalescent plastic members such as polymethyl methacrylate filters may be employed.

Title: Improvements in or relating to attachments for sewing machines
IPC: D05B29/06
Filed: 1961-06-12
Abstract: 937,680. Sewing-machines. NECCHI S.p.A. June 12, 1961 [July 22, 1960], No. 21114/61. Class 112. A buttonhole-foot for a sewing-machine comprises a support carrying a soleplate and a blade pivotally carried by the support for movement to a fabric penetrating position for cutting the fabric, within the sewn outline of a buttonhole, in response to movement of the fabric in the general direction of the buttonhole. A support 1 (see Fig. 4), secured to the presser bar has pivoted to it at 4 a sole plate 5. Pivoted to the support at 6 is a support 8 provided with a cutting blade 9, the support 8 being spring-biased into a raised position where the blade lies within the general confines of the support 1 and does not constitute a hazard to the operator. A handle 16 on one side of the support 8 allows the support and blade to be rotated down, the blade 9 penetrating the fabric inside a completed buttonhole and entering the needle slot 19 in the stitch plate 20. As the fabric is moved in the direction X pressure of the fabric maintains the knife in the lowered position. To control the length of the cut formed by the blade the foot is provided with a slider 22 having grooves 23, 24 (see Fig. 2), slidably engaged with the edges of the sole plate 5. The underside of the slider 22 has teeth 25 engaging the fabric 17, the slider moving with the work as the buttonhole is sewn. Fixed stops 27 and an adjustable stop 28 disposed at opposite ends of the slider engage ends 32 and 32 respectively, of the sole plate to limit the movement of the slider relative to the plate. After the buttonhole has been stitched the feed dog (not shown) is lowered, the blade 9 moved to penetrate the work and the slider moved, together with the work, to cut the buttonhole. At the end of the cut an inclined surface 41 on a second adjustable block 40 engages an appendage 42 (Fig. 2), to raise the blade before the bar tack is cut. To return the slider to its starting position when the foot is raised to move the fabric before commencing a new buttonhole, the slider has a spring- biased pulley 46 around which is wound a cable 48 having one end connected to the support 1. To permit the buttonhole to be sewn automatically, a lever may be pivoted to the support in such a manner that its lower end is engageable with inclined surfaces 57, 58 on the slider, the upper end engaging parts of the sewing machine described in Specification 902,346 to cause the automatic production of the buttonhole.
