Patent GB-1160006-A (GB)
Title: Microwave Linear Beam Tubes
Inventor: LEIDIGH WILLIAM JARED
IPC: H01J23/36
Filed: 1967-12-04
Abstract: 1,160,006. Klystrons. VARIAN ASSOCIATES. 4 Dec., 1967 [5 Dec., 1966], No. 55117/67 Heading H1D. In a klystron amplifier including an interaction section for bunching the electron beam and for extracting energy from the bunched beam, the interaction section includes at least one resonant portion having a plurality of coupled periodic elements for providing a plurality of gaps that interact with the beam, the coupled elements being so dimensioned that the phase shift between R.F. electric fields across adjacent gaps is n # where n is an odd integer. In Fig. 1 the output section 34 comprises four resonant cavities defined by the end walls 35 and three discs 38, 40 and 42. The outer cavities are differently dimensioned from the inner cavities because they are differently loaded by the couplings between cavities when operated in the n # mode, and should be such as to produce equal electric fields across all the interaction gaps at the resonant frequency. The discs 38, 40 and 42 may be wheel-shaped with four radial spokes (Fig. 2A, not shown) or may include kidney shaped coupling slots which may be staggered in the three discs (Fig. 2B, not shown). An alternative construction comprises a flat substantially rectangular member with a central beam aperture (Figs. 7 and 8, not shown), and a further alternative comprises a disc with an internal annular cooling channel and a central beam aperture which also provides capacitive coupling between adjacent cavities (Figs. 9 and 10, not shown). In Fig. 3, the output waveguide 58 is coupled by an iris 57 to the penultimate cavity, and rib members 59 are provided in the walls of the cavity to compensate for the electrical distortion caused by the iris 57. An alternative construction uses three cavities with the output taken from the end cavity (Figs. 3 and 3A, not shown). The cavities are separated by drift tubes having bevelled edges and surrounded by annular members including kidney-shaped coupling apertures.

Abstract: 1,253,678. Testing and making perfumes. R. RANDEBROCK. 21 Nov., 1968 [21 Nov., 1967], No. 55355/68. Heading A5B. Perfumes are compounded by determining the characteristic "scent values" of the components (see below) and mixing together components so tested in quantities which for each category of scent in question, satisfy the equation: where n is the total number of components, i is any one component, W i  is the scent value of that component, M i  is the amount thereof, W is the predetermined scent value corresponding to the desired scent effect E of the perfume composition and M is the total amount of the scent component in the perfume composition. The scent value W of a component is determined by measuring its scent effect E in respect of each of a comprehensive series of categories of scents (28 are referred to), the effect being expressed on a scale of 0 to 9 in which 1 is the minimum and 9 is the maximum scent effect and applying the formula: wherein W is the scent value, E is the scent effect of the undiluted scent components and A is a constant appropriate to the scent category.

Patent GB-554746-A (GB)
Abstract: 554,746. Valves. HOPKINSON, Ltd., DALE, W. B., and BARKER, J. April 15, 1942, No. 4967. [Class 135] A valve device adapted to close automatically upon failure of the fluid supply and remain closed until reset manually comprises a main valve a connected to a leaky piston c of larger effective area than the valve. Normally leakage past the piston equalizes the pressures acting on it so permitting the inlet pressure acting on the valve member to move it to the open position. An auxiliary valve e normally held to its seat against the action of a spring f by pressure in the chamber above the piston, opens when this pressure falls, consequent on a fall of inlet pressure, to connect the chamber above the piston to atmosphere and so permit pressure acting on the lower surface of the piston to close the main valve. The valve e is lifted into engagement with its seat to initiate the reopening of the main valve by means of a cap g secured to the valve spindle h. Depression of the cap will cause the main valve to close at any time. The lift of the valve a is limited by a stop i on an adjustable screwed spindle provided with a hand wheel j.

IPC: G03B27/58
Filed: 1968-11-25
Abstract: 1,190,148. Film changing in photographic copying apparatus. K. SCHUMACHER and E. SCHUMACHER (trading as KLIMSCH & CO. ) Nov.25, 1968 [Nov.25, 1967], No.55901/68. Heading G2A. A copying camera comprises means for transporting exposed film from the camera to a processing unit. As shown, film 11 from a carrier 5 is held on a suction plate 10 by vacuum apparatus 13, 14. After exposure, linkage 8, 9, operated by a motor 7, tilts the plate 10; a lever 15 thereon striking a stop 16 to open a vacuum-release valve 12. A shaft 19 is journalled to the camera body at 17, 18 and supports a horizontally extending bar 21 on which a plurality of fixed and pivoted jaws 24, 25, respectively, are mounted. Operation of a switch 6 energizes solenoids 23 which attract armatures 27 attached to jaws 25 to grip the film. A motor 30, through linkage 27, 28, rotates the shaft 19, and thus the jaws and film, through ninety degrees. Solenoids 23 are de-energized allowing jaws 25 to open through springs 22 to release the film on to a table (32), Fig.2 (not shown) of a processing unit (31). The sequence of operations is preferably automatic. In an alternative embodiment Figs.4, 5 (not shown), the vacuum release valve (33) is opened through a solenoid (34) energized on operation of the switch 6. Pairs of solenoid-operated jaws (41, 42) are mounted on respective vertical rods (37) all mounted on a horizontal shaft (36) which is rotatable to displace the rods (37) and thus the film gripped by the jaws. The film is released on to a belt conveyer (46, 50), which may feed the film on to rollers (58, 64), Figs.6, 7 (not shown) and then on to further belts (73, 78), Figs.8, 8a (not shown). Alternatively, the belt conveyer (46, 50) feeds the film on to three similar belt conveyers (81, 84, 85), Figs.9, 10 (not shown). The conveyers transport the film to the processing unit. Conveyer drive means, means for tilting and raising the conveyers and means (51, 53), (Fig.6) for aligning the film on the conveyers are described. It is stated that the invention is suitable for use in a roll film camera as described in Specification 1,049,654.

Abstract: 1,249,379. Vacuum cleaner. MITSUBISHI DENKI K.K. 20 Nov., 1969, No. 56830/69. Heading B1T. [Also in Division A4] A vacuum cleaner comprises a two-part casing enclosing an electric blower unit 22, 24 and an air filter 52 which is periodically cleaned by shaking it by means of a cranked lever 66, rotatably mounted in the central hub of a support 60 and secured to the filter at its lower end. In Fig. 1, dirt-laden air is drawn through hose 48, past resilient, ,self-closing valve 50, into dirt collecting chamber 12, then inwards through filter 52, aperture 28, blower 24, out through apertures 32 in the upper cover 30 of the blower unit, and then out through annular passage 70 between the casing halves. The blower unit is mounted in its enclosing covers 26, 30 by ruhber blocks 34, 36, and the covers are secured by bracket 38 to upper casing part 14. When the filter 52 becomes clogged, casing part 14 is lifted together with the blower unit to expose the interior of filter 52 and support 60. Support 60 comprises a peripheral ring 62 and three radial arms 64 extending downwards to hub 72. The two arms 80 and 86 of lever 66 are connected by a shaft with a round section, axially connected to a lower rectangular section, the shaft extending through bore in hub 72 with a narrow opening on one side (Fig. 4, not shown). By lifting the lever and moving it sideways, the lever is disconnected from the support 60, enabling the support 60 to be. inverted, after which the lever is reconnected thereto (Fig. 3). The lever is now rotated manually, shaking the inverted filter 52, and the dirt falls into chamber 12, which may subsequently be emptied after lifting the filter 52 and support 60 out. Filter 52 is rotatably and releasably secured to lever arm 86 (Fig. 5, not shown) and comprises several laminations of cotton or alternate laminations of cotton and nylon fabrics. Fig. 7 (not shown) illustrates a horizontally oriented cleaner, wherein filter 52 is shaken by an electric motor 100 and located permanently above removable dust collecting chamber 12.
