[Also in Groups XXXVI and XL (b)] A tubular waveguide component 20, Fig. 3, is made by depositing a layer of metal on a mandrel 13, Fig. 2, having one or more projections 16, 17 which non-conductive surfaces which are so arranged that after removal of the mandrel and its projections from the deposited coating, the latter will have slots 11, 12 corresponding with the projections. The deposited metal is preferably copper to which a layer of reinforcing material 21 may be applied before or after removal of the mandrel. The reinforcing material may be a synthetic resin or a metallic substance; alternatively, a resin impregnated fabric may be wound around the deposited metal to provide a thin reinforcing cover. The mandrel 13 with its removable blocks 16, 17 forming the projections, may be made of stainless steel and the projecting parts of the blocks are made non-conductive by a coating of an acrylic resin. Alternatively, the mandrel and projections may be formed integrally of a fusible material such as wax which is subsequently melted out of the deposited coating, or the mandrel and/or its projections may be made of a synthetic resin, preferably a soluble type such as acrylic resin. In this case the mandrel surface to be coated is rendered conductive by applying ammoniacal silver. Specification 790,191 is referred to.

Patent GB-586903-A (GB)
Title: Improvements in the manufacture of ceramic bodies
IPC: C04B33/13
Filed: 1944-12-06
Abstract: A ceramic body, particularly for use in the manufacture of dielectrics for condensers, is made by mixing the powdered ceramic material with polyisobutylene, the mixture being then shaped and heated to drive off the binder and finally to cause the ceramic material to sinter.  The polyisobutylene may be of an average molecular weight of 50,000-200,000, and it may compose 50-60 per cent. by volume of the total mixture.  The ceramic material, e.g., rutile, may be incorporated by working on rolls heated to 100 DEG C., and then in a Banbury mixer, a vacuum being applied to remove entrapped gas.  The product may then be calendered or pressed in moulds.  Firing may be carried out in two stages in a single-chamber or two-chamber furnace, the first stage involving heating to 500 DEG C. to remove the binder, and the second requiring heating to 1400 DEG C. to sinter the ceramic material.

Abstract: 361,827. Fire, police, and like alarm systems. MAKHONINE, I., 11, Rue BrÚmontier, Paris. Aug. 31, 1931, No. 24477. Convention date, Aug. 29, 1930. [Class 40 (i).] The setting movements of a dial-type transmitter for certain multi-digit numbers are effected by the passage through a slot 10 of a disc 17, Fig. 2, appropriate to the desired number, the disc having apertures 21 adapted to engage a pinion 9 geared with the finger-plate 3 for successive periods in accordance with the spacing of a series of holes 23. The disc is held in engagement with the pinion 9 by a spring-pressed plate 16, and, as soon as the dial moves off-normal, a stop 18 controlled by its restoring spring is removed from a lever 11, allowing a second spring-pressed plate 13 to bear against the disc, so that it is moved laterally out of engagement with the pinion as soon as the first of the holes 23 comes opposite a projection 20 adapted to engage therein. The dial then transmits the first train of impulses, and on its return to normal, the stop 18 strikes the lever 11 and retracts the plate 13 to allow the next setting movement to take place. The operation continues until the complete number has been transmitted. By this arrangement; the dial may be operated automatically to call the fire station or police station. The appropriate disc is then provided with a driving weight and ia held suspended over the slot 10 by a catch which is removed to release the disc by the energization of a relay controlled by a thermostat or by a burglar alarm, means being provided to lift the telephone receiver at the same time. The subscriber may be warned by an alarm signal, and will find himself in Communication with the fire station or police station. If desired a phonograph may be started near the microphone to transmit the address of the building.

Abstract: 833,665. Washing machines. BAUKNECHT G.m.b.H., G. Aug. 10, 1956 [Aug. 16, 1955], No. 24600/56. Class 138 (2). An agitator 2 is mounted on a crank 4 or eccentric so as to be movable bodily in an orbital path whilst being maintained in the same general orientation, and means are provided to vary the eccentricity of the crank or eccentric to vary the orbital path of the agitator. As shown, the agitator 2 is mounted on a pin 3 on the crank 4 and is peripherally held by means of a rubber or like flexible sheet 7 which is attached at its circumference to the inside of the washing vessel. Alternatively the machine may be provided with one crank for imparting orbital motion to the agitator and another crank for maintaining the same general orientation of the agitator. The crank-pin 3 is carried by a toothed element 3<SP>1</SP> inserted into an eccentric and toothed recess in the crank 4, thereby permitting adjustment of the eccentricity of the pin 3 in relation to a driving shaft 5. Alternatively the crank-pin 3 may be carried by a block slidably disposed in a radial keyway in the crank, and connected with a control rod whereby the eccentricity of the crank-pin 3 can be varied from zero to a maximum by manual or automatic means. The arrangement may be such as to permit a gradual increase in the eccentricity of the crank-pin and therefore a gradual intensification of the washing effect. While the agitator 2 is executing its orbital motion the flexible sheet 7 is being flexed and thereby transmits a pulsating action to the wash liquid.

Where unwanted images 14, 15 are produced these are either blocked off or formed so angularly displaced from the desired images 12, 13 that they are not viewed from said direction. If desired a plurality of such holograms Fig. 4 (not shown) may be arranged side by side and illuminated with a single or a selected set of light sources common to all the holograms, one image being reconstructed from each hologram to set up a message. The light sources are obscured by an opaque member. Multiple holograms are recorded either by changing the angle between one beam and the recording medium together with a change of data mask between exposures; or they may be recorded simultaneously as shown in Fig. 6. In all cases the object beam(s) are reflected from concave mirrors to a focal point, 39, 40 Fig. 6, before impinging on the hologram plate 31. A data mask 42, 41 is incorporated in each beam before the focal point. The reconstruction beam sources (which may be tungsten or mercury are of small size) are located at the positions of the focal points e.g. 39, 40. The viewing direction is then normal to the hologram. The holograms may be transmissive, reflective, volume or "thin", or they may be bleached holograms or formed as variations in surface contours in photo-resist material.
