Title: Process for the preparation of quick-cooking legumes
IPC: A23L11/10
Filed: 1966-12-05
Abstract: A process for producing quick cooking dry legumes comprises optionally presteaming the legumes at atmospheric presure, treating the legumes with hot water to adjust their moisture content to 40-62% by weight, steaming at a pressure of 0.3 to 1.5 atmospheres above atmospheric pressure for 50-5 minutes while the legumes are in a less closely packed condition than they are in a static condition, releasing the excess pressure such that the structure of the legume is opened and pores and small fissures are formed without the legume being entirely split open and drying the product.  The total excess pressure may be released in 0.02-1.0 sec. or when the excess pressure is greater than 0.4 atmos., the excess pressure may be reduced to 0.4 atmos. in 0.02-1.0 sec. and the remainder of the excess pressure is then released.  The legume may be pressure steamed in a rotating cylinder or on a vibrating screen.  The legumes may be fluidized during pressure steaming. The pressure steaming may be carried out in a continuous manner. The release of pressure may be continuous or discontinuous.  The legumes may be air dried.  The hot water may contain salt, sodium bicarbonate, citrates, zinc, copper, manganese or sulphites. Glycerol, sugars, gums, starches, phosphates may be added to the hot water or added to the legumes after the release of pressure. The process can be applied to lentils, green and yellow peas, white, yellow, red, brown and black beans, soya beans, marrowfats and chick peas.

A device for longitudinally cutting webs of paper or the like comprises a cutter shaft 12 on which is keyed a hub 1 having an annular disc 2 rotatably mounted thereon, the hub rim being provided with a ball 6 engageable in a recess or bore 7 in the disc 2 which is biased towards the hub rim by means of a spring 3, the arrangement being such that when the disc 2 is rotated by a handle 24 to a clamping position, the ball 6 engages in the bore 7 and a razor blade 5 may be held between the hub rim and the disc 2, and when the disc is rotated to a position permitting changing of the razor blade, the ball 6 causes the hub rim and disc to be spaced apart a distance greater than the thickness of the blade 5. The bore 7 has straight or curved surfaces extending obliquely in relation to the surface of the disc 2. The position of the blade 5 is determined by means of projections 8 on the disc 2, the projections engaging a groove 10 in the hub 1. The hub is provided with a flat 9 (Fig. 3) on its outer periphery to permit the blade 5 to be changed. The bore for the cutter shaft 12 is disposed eccentrically in the hub 1.

Title: Improvements in or relating to Directional Antenna Systems for Very Short Radio Waves.
Inventor: BRUNNER ANTON
IPC: H01Q11/04
Filed: 1967-12-01
Abstract: 1,195,900. Aerials. SIEMENS A.G. 1 Dec., 1967, No. 54702/67. Heading H4A. In a directional aerial system comprising an end-fed strip conductor which follows a path having periodic transverse deviations and which is arranged above a reflector plate, effective individual radiator sections have differing path lengths and differing valves for the ratio of width of the strip conductor to height above the reflector plate. As described, a strip conductor 1, Figures 1, 2 (of which one-half only is shown in Figure 1), consists of a plurality of trapezoidal sections which are mounted on a reflector plate 2 by means of fibre-glass supports 3. The outer conductor of a coaxial feeder 5 is connected to the reflector plate 2 and its inner conductor 7 is connected to the centre of the strip conductor 1. Each interval J between the centres of adjacent trapezoidal sections of the strip conductor is approximately equal to #/2 (# = mean operating wavelength) and there is a systematic increase in the lengths of the intervals from the centre to the ends. Also, the width b of the strip conductor 1 decreases along the conductor from the centre, and by these variations, it is stated, a desired beam shape may be obtained. In order to compensate for reflections, the strip conductor 1 may be provided with projecting parts, either fixed, as at 4, or movable, as at 8. In a second embodiment, Figs. 5, 6 (not shown), the spacing h of the strip conductor from the reflector plate is varied in a predetermined manner in order to obtain a modified cosec<SP>2</SP> type beam shape, Fig. 3 (not shown). In a third embodiment, two separate strip conductors 11, 18, Figs. 7, 8, are mounted in line on a reflector plate 12 and are connected by coaxial lines 20a, 20b to two opposite ports of a strip-line hybrid ring junction 21, which is mounted at the back of the plate 12. Coaxial lines 22, 23 are connected respectively to the sum and difference ports of the hybrid ring junction 21, and the aerial may thus be used for monopulse operation. A fibre-glass radome 15 is provided which is fixed along the longitudinal edges of the plate 12 and which carries embedded wires 16 for suppressing any radiation which is polarized parallel to the longitudinal axis of the aerial. No wires 16 are positioned immediately in front of the strip conductors 11, 18 or in the marginal parts of the radome 15 adjacent the plate 12. In a fourth embodiment, Figs. 9, 10, 11 (not shown), a further metal plate is fixed behind the reflector plate by means of two longitudinally extending metal strips, which are inwardly disposed from the edges of the plates by a distance of #/4. By this construction, quarter-wave traps are provided which reduce back-lobes of radiation from the aerial. .

The tubes 9, 10 are linked by corrosion resistant members 13 having appropriate bores for receiving the tube ends, tubes 9 being preferably welded to members 13 before insertion into bores 15, and tubes 10 being pressurerolled into engagement, in situ. Moulded corrosion-resistant members 14 with recesses 21 for receiving sealing rings are provided at the engagement surfaces 12 between the rotor shaft 1 and an energizing shaft 2. The corrosionresistant material may be austenitic steel, or a steel having a thermal expansion coefficient similar to that of the shaft 1. The chamber 6 is also formed from corrosion-resistant material. Owing to the firm contact between the tubes and the bore walls, the arrangement prevents leakage of cooling liquid even if localized cracking occurs in the lining tubes. A central rotor bore 3 carries current supply lines (not shown).
