Title: Measuring arrangement, more particularly applicable to distant measuring
IPC: G08C19/26
Filed: 1930-10-31
Abstract: 364,728. Electric signalling systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 31, 1930, No. 32780. Convention date, Dec. 13, 1929. [Class 40 (i).] In a remote metering system in which readings are transmitted by currents of various frequencies, the frequency of the impulses can be altered by constant terms to allow the receiver to measure consecutive ranges on a single instrument. As shown in Fig. 1 the readings of an instrument 1 are to be indicated at 8. The commutator 4 is driven by 1 through a gear chain and transmits impulses the frequency of which indicates at 8 the speed of rotation of 1. If the rate is such that 8 reaches its highest indication, the motor 10 is started and this drives 9, in the same direction as 4, at a predetermined fixed rate. The frequency of the impulses transmitted is thus reduced by a fixed amount and the pointer of indicator 8 again moves over the scale. The indicator 8 is provided with a multiple scale as shown in Fig. 3, the marker 8a indicating which scale should be used. A stop is provided to prevent false readings being transmitted due to 9 travelling at a faster rate than 4. The frequency of the impulses transmitted may be varied by providing a braking disc on the shaft of the instrument 1 or the indicator 8 may be provided with means which, when set in operation, reduce the frequency indicated by predetermined amounts.

Title: Improvements relating to electrical signalling systems
IPC: H04J1/12
Filed: 1933-11-23
Abstract: 426,664. Multiplex signalling. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and ROSEN, A., 163, Fordwych Road, Cricklewood, both in London. Nov. 23, 1933, No. 32813. [Class 40 (v)] In a two-way multiplex system, the available frequency spectrum is divided into two parts and each communication channel is allotted one frequency band above the line of division and one below, the bands above the dividing line being used for one direction of transmission and the bands below for the other direction, the two adjacent bands immediately on each side of the dividing line being used for one communication channel. If more than one metallic circuit is used, a similar allocation of bands is made for each circuit. By this means, the only effective cross talk is distant end as regards channels using different metallic circuits or different frequency bands, and near end cross talk between the two paths of the channel at the dividing line. This near end cross talk need only be reduced to a value giving stability and freedom from interaction between the amplifiers since communication only occurs in one direction at a time. With the exception of the central channel, paths in opposite directions are separated by at least one band and close spacing of the bands is permitted. As balancing for near-end cross talk is substantially avoided, the cross talk can be compensated by electromagnetic or capacitative coupling at the ends of the circuits, the electromagnetic couplings, e.g. coils being adjustable to facilitate compensation after cable repairs. The circuits may be phantommed, the bands on the phantoms being arranged similarly to the side circuits, balancing being, at least, effective for distant end cross talk between the central channels of the side and phantom circuits. Two-way single-band telephony and sub-audio telegraphic channels may be worked below the multiplex system described above.

Title: Improvements in or relating to the press-bordering of sheet metal

Abstract: 938,394. Seaming. FORD MOTOR CO. Ltd. (Ford-Werke A.G.). Aug. 27, 1962, No. 32823/62. Class 83 (4).  A process for press bordering sheetmetal parts, e.g. vehicle doors, in which a single bordering bar is moved for pre-bordering bodily along a circular arc and for end bordering is pressed against the workpiece in downward direction. The apparatus comprises a body 1 slidable on a guide 5, on which is mounted a bordering bar 2, the body is spring 6 loaded against a stop 12 mounted on the guide, and a base 3 provided with a work-holder surface 7 and abutment 14 on which is mounted a workpiece 13. The guide is connected to the base by a pair of parallel links 4 and a segment 10 hydraulically operated by a unit 9 to move the guide along a circular path. The amount of pre-bordering is limited by an adjustable stop 11. The upwardly bent edge of a workpiece 13 located against the abutment 14 is pre-bordered and subsequently end bordered by the bar 2 which is moved downwardly by an hydraulically operated unit 8 attached to the body which reacts against the underside of the surface 7 to overcome the spring 6. In a modification the apparatus comprises coupled inner and outer units. The outer unit is identical with that described above whilst the inner unit is substantially the same. The inner unit is raised into its working position by an hydraulic jack 15 between guides 16 and a stop 17 and a bar 54 acts as an arrester for a workpiece 53 supported on a part 47 when in the working position. In the rest position the upper surface of the inner guide means 45 is shaped as a support 27 for the outer unit for a workpiece 33. The guide 45 is provided with a cam 55 which meshes with an aperture of the outer bordering bar 22. Vehicle doors of the same shape but of a different width are bordered in this embodiment, wide doors being bordered using the outer unit with the inner unit at rest. For narrow doors the inner unit is raised to its working position, the workpiece 53 positioned on the surface 57 against the bar 54 and the outer unit actuated as before to drive the inner unit via the cam 55. An hydraulic unit 48 actuates the bar of the inner unit to end border the workpiece. A series of units may. be arranged to border metal parts in one operation.

Abstract: 1,087,157. Aerials; R.F. couplings. KAMAN AIRCRAFT CORPORATION. Oct. 10, 1964 [Oct. 11, 1963], No. 32967/64. Heading H4A. A radiating or receiving antenna comprises a conductor and a multi-turn coil (or coils) resonant at a particular frequency, the coil having portions lying parallel to the conductor, the portions being each so small compared with the wavelength at the operative frequency and the coupling between the coil and the conductor so great that an abrupt reversal of the current standing-wave in the conductor occurs in the vicinity of the coil. The coil or coils may be of toroidal form with the conductor arranged on the axis of the toroid and the inner portions of the turns of the coil running straight and parallel to the conductor. Two semi-circular toroidal coils may be wound on the same former and connected in parallel (Fig. 2, not shown). In the embodiment of Fig. 3 the conductor is a sheet 34 and the coil consists of a number of portions 36a-36d spaced along the axis of common insulative former and connected together in parallel. The coils may be self resonant or may (as shown) be tuned by a capacitor 16. The sheet 34 may e.g. be part of the surface of a missile and the coil may extend circumferentially around the missile, in which case the former 38 is annular. The coil (46, Fig. 4, not shown) may be accommodated in a circumferential groove (44) near the nose of the missile. The groove is covered with a conductive fairing (48) which is insulated from the rest of the missile along one edge of the groove. It is stated that the effect of the coil is to isolate one part of the structure from another at the resonant frequency whereby the structure may be used as an antenna without need for mechanical discontinuity. A similar use (Fig. 7, not shown) enables the legs of an aerial tower to be isolated from earth by coils surrounding the legs. The coils may be used in a passive or an active mode; when used in the latter mode they are connected to a high impedance input. The aerial of Fig. 6 (not shown) consists of an active coil (62) arranged near the central point of a straight conductor (66) and passive coils (62) spaced on either side of the central coil. The voltage standing-wave pattern (68) shows voltage nodes at the positions of the coils and single halfwave periods, all either positive or negative, between the coils. It is stated that an improved directional characteristic is obtained. A multi-frequency antenna (Fig. 8, not shown) is described in which a series of passive coils all tuned to different frequencies are spaced along a radiating conductor. The antenna is fed by a single active coil.
