IPC: H01S3/0975
Abstract: 1,031,224. Masers. WESTERN ELECTRIC CO. Inc. Feb. 7, 1963 [Feb. 23, 1962], No. 4971/63. Heading H3B. In an optical or microwave maser amplifier, a quartz piezo-electric element 13 transmits a mechanical wave, frequency fac, along a ruby rod 10 and a signal wave 17, frequency f 1 , is reflected to and fro between a wave peak of the mechanical wave and the interface between the ruby rod 10 and the element 13. There is a Doppler shift of frequency on reflection and there results a series of wave trains of frequencies f 1 , f 2 , f 3 , f 4  &c. where f 2 , = f 1  - fac, f 3  = f 1  -f 2  fac, f 4  = f 1  -f 3  fac &c- A pumping wave 19 is applied to the ruby either laterally in known manner or endwise as described in Specification 1,012,835. The change of frequency on reflection permits amplification without self-oscillation. The piezo-electric element is driven by electromagnetic wave energy from a source 12, the cavity 11 being resonant at the same frequency. The opposite end of the rod 10 is terminated optically and acoustically by a first portion 14 of optically absorptive material such as black sapphire and a second portion 15 of acoustically absorptive material such as ruby with rough surfaces. The mechanical wave and the signal may be transmitted in opposite directions as shown in Fig. 4. The transducer 43 is coupled to the rod by light-absorbing material 42. The cavity 41 in which the transducer 43 is mounted is placed on a Dewar flask 44 maintained at the temperature of liquid nitrogen (77‹K). The signal wave may be transmitted at an angle to the mechanical wave, Fig. 5 (not shown) . The end of the rod through which the signal wave is introduced has a totally reflecting portion 50 which may be perpendicular to the rod axis, as shown, or may be tilted. The input and output channels for signals 17, 18 may be coupled to the rod by a circulator comprising optical polarizers and polarization separators.

Title: Semiconductor device - e.g. containing an insulated gate - or field-electrode
IPC: H01L23/29
Filed: 1974-04-05
Abstract: Mfr. of a semiconductor device by applying a first electrically insulating layer on a surface of a part of a semiconductor body of a first conducting type; applying a layer of a second conducting type converting the first and second layers into a desired pattern by etching, whereby a part of the first insulating layer situated below the edge of the remaining part of the second conducting layer is removed at least locally, and then chemically converting a surface layer of the semiconductor body into an electrically insulating material, so that the space formed by under-etching between the edge of the second layer and the semiconductor body is at least partly filled. The break-down potential across the space produced by under etching in the usual technique is significantly lowered and may fall further due to a accumulation of impurities which are difficult if not impossible to remove. The electrical and mechanical props. are markedly improved by partial and pref. the complete filling of such spaced by the insulating layer.

Title: Determining system for angular position of spinning projectile - uses low frequency carrier wave horizontally polarised w.r.t. each surface independently on transmitting aerial orientation
IPC: F41G7/30
Filed: 1988-05-09
Abstract: The trajectory of a spinning projectile (1) is tracked by radar (4) located on a ship and its course is corrected by firing gas discharge units (6) to reach a target (2) tracked by a second radar (3). To ensure that the gas discharge units are fired at the instant when the spinning projectile assumes the correct position, transmitter (8) sends the information about the desired projectile angular spin position 'phi g' calculated by a computer (5). To enable the projectile to determine its instantaneous angular position w.r.t. the earth surface, transmitter (7) with its associated vertical antenna transmits a low frequency carrier wave whose electric field component is vertically polarised and the magnetic field component is horizontally polarised w.r.t. the earth surface. This polarisation is independent of the antenna orientation. A comparator (12) on the projectile compares the instantaneous angular position from the signal received by system (13) with the value 'phi g' received from the ship by the receiver (9) and activates the gas discharge unit at the moment when both values are equal.

Title: Kitchen cabinet
IPC: A47B77/04
Filed: 1992-03-19
Abstract: Existing (kitchen) cabinets which are positioned beneath a draining board or work surface have the drawback that the objects which are placed on the shelves of such a cabinet are not readily accessible and that it is difficult to gain an overview of the contents of the cabinet. A further drawback is that it is not easy to sit on a chair or stool at various positions at such a work surface with cupboards below. The invention solves this problem by providing a cabinet in which each of the shelves is in the form of a semicircle, the straight front side of which is fixedly connected to an associated door section, which door sections together form the door of the cabinet. The shelves of the cabinet can be rotated with the associated door sections through at least 90 degree on either side, about a vertical axis which lies behind the centre of the door sections. <IMAGE>

Title: Reclosable dispenser package reclosable outlet forming structure and method and apparatus for makingsame
Inventor: REDMOND SANFORD
IPC: B65D75/32
Filed: 1998-07-23
Abstract: An aperture forming structure, which when attached to or integrally formed in dispenser packages for flowable substances allows reclosure and single or multiple uses. The aperture forming structure includes a break away tip member of thermoformable plastic. The break away tip includes a hollow protrusion from a surface. The intersection of the hollow protrusion and the surface is a fault line. Rupturing of the fault line creates an aperture from which the contents of the dispenser package may exit. A cap may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture created when the fault line is ruptured. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and a second hollow protrusion in a tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions. The sheet may be attached to a pouch or containment member formed from a flexible sheet which contains any flowable substance.

Title: Process for the preparation of a reforming catalyst composition
IPC: A01N/
Filed: 1980-02-15
Abstract: New reforming catalysts comprise a mixt. of 2 types of particles (A and B). Particles A comprise a minor amt. of Pt and Re on a refractory support and particles B comprise a minor amt. of Ir on a refractory support. The catalysts offer a high degree of flexibility in that the (Pt+Re):Ir ratio can be adjusted to suit the feed compsn. by varying the proportions of A and B and/or their compsn. They have better stability than conventional catalysts (including mixts. of Pt/support and Ir/support particles), esp. under high-severity reforming conditions.
