Patent GB-2200317-A (GB)
Title: Isostatic moulding
Inventor: BUTLER EDWIN GRANVILLE
IPC: C04B35/593
Filed: 1988-01-14
Abstract: A method for the hot isostatic pressing of green bodies comprises the encapsulation of the green body with paste formed from a mixture of boron oxide powder, glass-forming powder and water. The paste is dried to form a hard, protective cement-like shell around the green body. The coated body is then hot isostatically pressed in the vessel of a hot isostatic press after raising the vessel interior to a temperature where the coating forms a viscous impermeable membrane. The coated green body may be further supported in a powder bed within a container within the pressure vessel. An example using a silicon nitride green body is given.

Title: Preparation of binary alkali/alkaline earth-metal non-metal complexes
Inventor: SNAITH RONALD
IPC: C07F9/68
Filed: 1989-05-19
Abstract: Complexes of an alkali or alkaline earth metal M, with a semi-metal or non-metal X, and an organic liquid L, and especially alkali metal sulphide complexes with Lewis bases such as tetramethyethylene diamine (TMEDA), are prepared by the reaction of a source of the metal M, e.g. the metal itself, a metal hydride, a metal alkyl or a Grignard reagent, with a suspension of the elemental semi-metal or non-metal component X in an organic solvent, e.g. toluene, in the presence of the liquid L. The complexes are of the general type (MxXz.nL)y and ([M<1>Hal]xXz.nL)y where M1 is an alkaline earth metal, Hal is halogen, x and z are numbers indicating the molar ratio of the metal to the semi- or non-metal, n is a number such that n:1 is the molar ratio of the liquid to alkali or alkaline earth metal/semi- or non-metal salt in the complex and y is an integer up to infinity. Especially important as a potential source of pure lithium and as organic solvent soluble lithium source are lithium sulphide complexes of the formula (LixSz.nL)y.

Title: Method and device for removing objects
Inventor: NILSSON LEIF
IPC: B65G47/84
Filed: 1990-10-05
Abstract: The invention relates to a method for transferring objects (1a, 1b) from a conveyor (2) to a receiving station (B) beside the conveyor by means of a rotor (10a) having a shaft (9, 10) extending substantially in the longitudinal direction of the conveyor and comprising at least three blades (11a-e) projecting from the rotor shaft and adapted to engage and transfer the object. The position of the object on the conveyor (2) is sensed. A first blade is adjusted in an initial position (I) at one longitudinal side edge of the conveyor. The moment for activating the rotor is calculated, and the rotor is actuated at said moment, such that the first blade during transfer of the object is moved from a position of rest (III) at the other longitudinal side edge of the conveyor, and that a second blade is simultaneously adjusted into said initial position (I). The invention also relates to a device for carrying the method into effect. The device has a means (502) for sensing the position of the object on the conveyor (2) and a control means (500, 501, 504, 505) adapted to receive a position sensing signal from said sensing means and to supply in response to said signal an activating signal to said drive means (3, 6) for activating the rotor (10a).

Title: Antenna selecting diversity receiving apparatus
Inventor: ANDOH AKIRA
IPC: H04B7/08
Filed: 1991-05-24
Abstract: The apparatus is used in a TDM system with a linear modulating wave (BPSK, QPSK or 16 QAM) and has an integrating circuit 15 which integrates the signals from antennas 11, 12 for respective predetermined time periods prior to the start point of each TDM time slot allotted to the receiver 14 in order to select which antenna should be used during that time slot. The selection may be effected by a comparator 17 which compares the integrated signal from one antenna with that from the other previously integrated and retained in a sample and hold circuit 16. A further comprator (19) may be provided operative during an allotted time slot for repeatedly comparing the integrated signal with a reference so that changeover between antennas is effected if the integrated value is below the reference, (Figs 10, 11). In an alternative embodiment, (Figs 12, 13), prior to an allotted time slot, the signal from each antenna 11, 12 is integrated for multiple respective predetermined time periods, and from the integrated values a prediction of the signal level during the time slot is made for each antenna. The antenna to be used during the time slot is selected in dependence on the predicted levels. <IMAGE>

Filed: 1992-02-26
Abstract: A drive mechanism for mechanically driven doors such as garage doors (D) comprises a motor (M) and guiderails (10) mounted to a frame defining a door opening, wherein the motor (M) drives a chain (14) which displaces vertically next to a side of the door. The drive mechanism includes a pick-up member (P) including an arm (16) connected to the chain (14) for vertical displacement therewith and a bracket (18) mounted to the door. The bracket (18) includes an inclined portion (30) extending upwards and away from the door. The arm includes a lost-motion opening (26) which is adapted to engage a shaft (22) connected to the door and forming a pivot therefor. The arm includes a drive member in the form of a cylindrical bar (28) abutting a lower part of the inclined portion of the bracket when the door is in its closed position and adapted to move upwards when the door is opened. Actuation of the motor (M) to open the door causes an upwards displacement of the chain (14) and thus of the arm and of the pick-up member (P) which moves upwards along the inclined portion for causing the door 10 pivot about its pivot shaft with the lost-motion opening (26) of the arm preventing the pivot shaft of the door from raising with the arm. After an initial upwards displacement of the arm corresponding to the lost-motion opening, the arm drives upwards the pivot shaft and thus the door which has an oblique orientation. <IMAGE>
