Title: Directional wave antenna for marine radar use
IPC: H01Q21/00
Filed: 1952-01-04
Abstract: 715,399. Aerials. KATCHKY, N., and BYERS, H. G. Jan. 4, 1952 [April 18, 1951], No. 370/52. Class 40 (7) A directive antenna assembly comprises a sectoral horn having upper and lower walls diverging from a throat to a mouth portion and a waveguide situated at the throat with its longitudinal axis parallel to the respective planes of the walls and having an array of slots cut in the side of the guide facing the mouth of the horn. In one embodiment intended for use as a radar scanner the radiator is a horizontally mounted slotted waveguide 10 in the throat of a flared horn 20. The waveguide is mounted by bolts and nuts 25 on the back wall of a casing 60 and spring clips 24 secure together the throat end of the horn walls and the guide between which spacing pieces 23 are interposed to provide a quarterwavelength choke section. The front edges of the horn sides are located in channel pieces 63 running along the top and bottom of the rectangular front aperture of the casing. Also located between the channel pieces is a vertical grating consisting of thin plates 71 extending in parallel planes perpendicular to the plane of the aperture and threaded on to rods along which they are regularly spaced by spacing elements 64. The plates 71 are spaced less than #/2 apart and the grating serves to attenuate the component of vertical polarization where substantially vertical but inclined slots are provided in the waveguide. A window 63a of radiation permeable material may be provided to seal the horn structure. The assembly is mounted for rotation and fed through wave-guide joint 50 and guides 40 and 81 leading to one end of the radiating guide 10. The arrangement may be resonant or non-resonant but it is preferred to make it non-resonant to achieve a greater bandwidth and to provide a power absorbing termination 30, Fig. 5 (not shown) on the opposite end of guide 10 to the feeder input. The slots in the front narrow face of the guide are approximately half a wavelength apart (200 degrees) and inclined alternately to right and left Fig. 4 (not shown). The ratio of field intensity at the waveguide ends is made an eighth of that at the centre to reduce side lobes and the specification contains theoretical discussions and graphs re'ating to the choice of amplitude taper, slot spacing, and slot inclination.

Title: Lubricating systems for engines
Inventor: LOVE PHIL PRINCE
IPC: F16N23/00
Filed: 1965-01-06
Abstract: 1,098,391. Lubricating; valves. GLACIER METAL CO. Ltd. Jan. 5, 1966 [Jan. 6, 1965], No. 615/65. Headings F2A and F2V. A lubricating system comprises an enginedriven pump supplying oil via a delivery passage to bearings whose operating conditions vary with those of the engine, and a relief valve allowing escape of oil from the delivery passage, flow through the valve being decreased under increased engine speed and/or increased engine load. In Fig. 1 upper and lower ends of piston 12 are connected via springs to a casing 13 and a valve head 10 respectively, the induction passage 11 being connected to the space above piston 12. Increased engine load produces increased pressure in passage 11 which through piston 12 increases the force urging the valve head 10 on to its seating thus restricting the flow of oil through the valve and increasing the pressure in gallery 4 supplying the bearings. Increased engine speed produces increased rate of flow of oil from pump 1 and thus increased oil pressure in gallery 4. In Fig. 2 (not shown) a check valve 6 is connected in series with a restrictor 16. The restrictor has a spring supported piston (21) carrying tapered member (20) which passes through orifice (16), the induction passage being connected to a space above piston (21). Alternatively the restricted orifice may have a constant cross-sectional area. The restrictor and/or relief valve may be controlled by engine speed, engine exhaust pressure, induction pipe pressure, temperature of part of the engine, or throttle or fuel injection pump setting.

Abstract: 822,323. Softening hard vegetable fibres. TURNBULL; R. H. Jan. 9, 1956 [Jan. 10, 1955; Oct. 27, 1955], Nos. 764/55 and 30808/55. Classes 120(1) and 120(3) Sisal and other hard fibres previously extracted from plants are softened by treating them with a liquor containing a cytase followed by repeated rolling. The fibres may be treated in succession with the cytase containing liquor and a liquor containing a softening chemical. The process may be applied to fibres of the agave, furcraea and yucca families, phormium tenax, abaca, hesperalie funifera, musa textilis, sansavieria, ramie and palm and palm like fibres. The cytases employed may be obtained from the plants from which the fibres have been extracted, or from the fibres, or from other plants or fibres, such as raw jute, as described in Specification 721,878. According to the Provisional Specification moulds and bacteria mentioned in prior Specification 721,878 may also be used A wetting agent may be added to the cytase liquor. Chemicals which may be used include ammonium phosphate, di-hydro ammonium phosphate, ammonium sulphate, ammonium carbonate, sodium sulphate, sodium phosphate, sodium orthophosphate and sodium carbonate; these may be employed in 20% solutions. Either spraying or steeping with the softening liquor may be effected; the steeping may be carried out under pressure. In an example of treatment, cytase liquor was first extracted from raw sisal fibre by soaking the fibre in water at 20-30‹C, or up to 60‹C. for 36 hours or more. Sisal fibres to be treated were then wetted with cytase liquor at 20-60‹C., rolled, soaked in cytase liquor for more than 24 hours at 20-60‹C., then rolled whilst wet and soaked in a 20% solution of di-hydro ammonium phosphate at a pressure of 15-75 lb./sq. inch. The fibres were rolled wet, dried and rolled again. The softened fibres may be mixed with other softer fibres when spinning. Rolling may be carried out in a machine as described in Specification 811,991.

Title: Charging switch device for stroboscope
Inventor: MURAYAMA TAKASHI
IPC: G03B15/05
Filed: 1993-01-04
Abstract: PURPOSE:To provide the charging switch device for a stroboscope which can surely charge a main capacitor with a simple operation, reduces the consumption of a battery and is low in the cost. CONSTITUTION:SWs 1 to 2 turn on and SW 3 switches the connection of a terminal E from a terminal D to a terminal C when a charging knob is pressed. As a result, the battery 35 starts charging capacitors 40, 41 and turns on a MOS type FET 42. The SWs 1, 2 turn off and the SW 3 switches the connection of the terminal E from the terminal C to the terminal d when the pressing of the charging knob is thereafter released. As a result, the capacitors 40, 41 are connected in series in the state of interrupting the conduction from the battery 35 and a synthesized voltage is impressed to a gate G and, therefore, the MOS type FET 42 is kept turned on, thereby the current from the battery 35 is kept supplied to a boosting circuit 43. The MOS type FET 42 turns off automatically to stop the supply of the current from the battery 35 to the boosting circuit 43 when the charges of the capacitors 40, 41 are discharged after the lapse of a prescribed time.

Title: Impedance bridge
Inventor: SATOU HIDEO
IPC: G01R17/12
Filed: 1978-01-06
Abstract: PURPOSE: To accurately subject the bridge output to level conversion by using one high gain voltage amplifier, i.e., an amplifier of low input impedance.  
     CONSTITUTION: The impedances of converting elements 2 to 5 are denoted at R 2  to R 5 , respectively, and in case an exciting source 1 is a current source the voltage E 0  between a common potential point e and the output terminal of an amplifier 10 is expressed by another Equation. Here, I s  designates the current of the source 1. In this instance, the converting elements 2 and 5 have their impedances reduced for a physical quantity X, whereas the elements 3 and 4 have their impedances increased. Then, the output E 0  becomes an output proportional to the physical quantity X. As a result, for the output of the impedance bridge, it is possible to effect the level conversion, by which the output on the basis of a potential point e can be obtained. Since, moreover, the middle point of the two sides of the bridge is used directly as the input of the amplifier 10, the amplifier may have a low input impedance when it is intended to obtain the same accuracy. And, the number of the amplifier may be only one.
