Title: Improvements relating to coupling devices for electromagnetic waveguides
IPC: H01P1/04
Filed: 1945-12-14
Abstract: 605,348. Couplings for wave-guide sections. ASHDOWN, G. L. Dec. 14, 1945, No. 33947. [ Class 40 (v)] [Also in Groups XXV and XXVIII] A coupling device for two tubular waveguide sections 1, 2, comprises a frame or sleeve 7 adapted to receive the tube ends, and a pair of parallel apertured plates 9 positioned on opposite sides of the frame, with their apertures each adapted to engage pins 6 on the respective tube ends and formed with oppositely inclined cam edges 27 so that as the plates are forced to move in their own planes the cam edges and pins coact to draw the members into abutting contact inside the frame. The lower parts 10 of the apertured plates pass through slots 12 in a guide member 13 and are then joined by a tension spring 18, while the upper parts 11 pass through notches in a member 16, being then fixed to a bridge-piece 19 by means of split pins. A screw 23 passes through the bridge piece, and has a groove near its end which engages a raised part of the member 16 so that the latter will not move on turning the screw. To effect a coupling, the tube ends are inserted in the frame so that the pins project through the apertures in the plates 9 and the screw is then tightened so that these plates are moved upwards and the co-operation of the edges 27 with the pins causes the tube ends to be drawn into intimate contact. To release the coupling the parts 28 of corresponding sides of each plate are pressed between finger and thumb; this causes the other sides of the plates to move apart so that the tube can be removed from that end. A similar device may be used for coupling circular section tubes.

Title: Improvements in or relating to the recording and reproduction of impulses such as those of audio frequency
Filed: 1934-11-29
Abstract: 447,205. Diaphragms. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Nov. 29, 1934, No. 34342. Convention date, Dec. 28, 1933. [Class 40 iv] Sound reproducing or recording devices are provided with means for producing " turbulence damping," i.e. the damping produced by causing a turbulent motion in a fluid such as air. Such damping is proportional to the cube of the air velocity and so, in the neighbourhood of the resonance frequency of the instrument concerned, reduces the response to high level vibrations to a much greater extent than that to low level vibrations. The Figure shows an instrument in which a mirror is controlled by a diaphragm 20 for making an optical record. The space behind the diaphragm is, in order to produce " turbulence damping," closed by a thin perforated sheet 25. A similar instrument not forming part of the invention has a comparatively thick porous back instead of the sheet 25. This arrangement gives an approximation to viscous damping. Reference is made to a cutter in which the response at the upper and lower ends of the spectrum depends primarily on mass and stiffness respectively and in the region 2000 ... 4000 depends on turbulence damping. No constructional details are given.

Abstract: 433,450. Prospecting for minerals &c. MACHTS, L., 90, Weidenhauserstrasse, and REHDER, B., 2, Universitatstrasse, both in Marburg-on-Lahn, Germany. Dec. 11, 1933, No. 34877. Convention date, Nov. 20. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 11, 1934.] [Class 37] In a method of investigating geological structure a detection apparatus having an antenna is moved over a chosen path and is adapted to give substantially continuous indications in the form of oscillograph diagrams and means are provided for recording such indications automatically when desired and for indicating simultaneously the position of the apparatus on the chosen path when such records are being made. In the arrangement shown, a small frame aerial or antenna 4, arranged to be swingable about its axis 5, is connected to a receiving and amplifying apparatus 1. The received signals are led to the control electrodes 10 of a cathode ray tube, the beam 9 from which is directed on a recording band 7 of sensitive material. A record is obtained of the local electric fields produced either by a normal broadcasting station or by a station radiating a given wave-length for the purposes of the investigation, the aerial of the station preferably having a substantially vertical portion. The frame aerial 4 is preferably oscillated during the investigation, giving rise to maxima and minima 12, 12a in the oscillogram 13, Fig. 1a. The angular changes in position of the aerial are preferably recorded on the band 7 by a curve 13b, which may be marked on the band before the latter is actually used if the cyclic displacement of the aerial is predetermined. Marks are also made on the band along a line 13c, to indicate the distance of the receiver from a known starting point in the region under investigation. This may be effected by mechanical interconnection between the transporting means for the apparatus and the drive of the recording band. When the receiving apparatus moves over a fault 18, Fig. 2, or other irregularity in the geological structure, a change in the oscillogram, such as a displacement 13a is produced. In a modification, Fig. 3 (not shown), an open antenna is used. The Specification as open to inspection under Sect. 91 is not restricted to a method using oscillograph apparatus, but claims generally a process and apparatus for the indirect determination of ground and air electrical conditions in which the geology, morphology, stratigraphy and tectonics of the ground are determined by means of any desired geophysical process. The results are stated to be applicable in determining the most suitable sites for grounding lightning conductors or for erecting laboratories, plantations, stables and the like. This subjectmatter does not appear in the Specification as accepted.
Patent GB-411534-A (GB)
Title: A cellular clay body and method of producing the same
IPC: C04B38/02
Filed: 1932-12-09
Abstract: A light porous clay product having a large number of non-interconnected cells which is suitable for the preparation of building blocks is produced by generating a gas in a fluid clay slip containing plaster of Paris which contains added carbonate, by the incorporation of an acid, preferably a dilute acid, while the slip is in a fluid condition.  The mass is allowed to expand in a mould, dried, and fired.  The viscosity of the cell walls and consequently the amount of the expansion is regulated by the amount of plaster of Paris present.  The preferred carbonaceous material is dolomite.  The product has a density of about one half that of the argillaceous material used in its preparation, and may be cut, or otherwise mechanically worked.  The surface may be glazed in known manner before the product is fired.  In an example, 100 lbs. clay (passing a 20 mesh sieve), 10 lbs. plaster of Paris and 3 lbs. dolomite (60 mesh) are treated in a blunger containing 65 lbs. of 3 per cent sulphuric acid for 1 to 2 minutes.  The mass is then poured into moulds.
