Title: Snap acting switches
Inventor: BURCH LYNDON W
IPC: H01H5/04
Filed: 1990-01-24
Abstract: A snap acting switch comprising an elongate cantilever mounted spring member 208 (also Figs. 10, 12) having a contact portion, electrically conductive resiliently deflectable elements 182, 184 upon which the contact portion bears, and an actuator 190 having surfaces intersecting at an angle, one of the surfaces bearing on the spring member. The switch is actuated by causing the spring member to approach and pass over the intersection of the surfaces, which causes the bearing pressure of the contact portion to increase before the snap action occurs, and provides a wiping action. A thermostatically operated or current overload embodiment is detailed (Figs. 14-16) including fixed but adjustable actuator (270) spring wire contact member (260) and bimetal electrically conductive strip (262). <IMAGE>

Title: Method and apparatus for generating energy
Inventor: LO SHUI-YIN
IPC: G21B3/00
Filed: 1990-04-12
Abstract: A method of generating energy by decay of coherent boson ions wherein the boson ions are present in a solution can be carried out by directing coherent infra-red light from a laser 15 into a solution 14 containing deuterium ions. The solution is retained as the core of an otherwise hollow glass fibre 12. The effective refractive index of the glass of the fibre 12 is preferably equal to that of the solution 14. Alternatively microwave radiation may be utilised, or an electric field may be produced by electrodes to render the deuterium ions coherent. Other boson ions may be used instead of deuterium. <IMAGE>

Patent GB-2238619-A (GB)
Title: Dielectrophoretic characterisation of micro-organisms and other particles
Inventor: BETTS WALTER BERNARD
IPC: C12Q1/06
Filed: 1990-11-27
Abstract: Dielectrophoretic collection rates of microorganisms or other animate or inanimate dielectrically polarisable particles in suspension in a fluid are established by flowing the suspension past electrodes (17, 18) energised to produce a non-uniform alternating electric field in the suspension, terminating the energisation of the electrodes after a predetermined time to release particles collected from the suspension, and, downstream of the electrodes, measuring the pulse of released particles as a measure of the rate of particle collection during energisation of the electrodes. Repeated measurements at different field frequencies enable a collection-rate spectrum to be established and the particles under examination to be characterised or identified by reference to known spectra of known particles.
Patent GB-909973-A (GB)
IPC: C10K1/34
Abstract: 909,973. Purifying gas. GAS COUNCIL. Nov. 16, 1960 [Nov. 18, 1959], No. 39084/59. Class 55 (2). In a process for removing organic-sulphur compounds from hydrogen-containing gases the gases are passed at 300‹-450 C., preferably 320‹-450‹ C., over a contact material containing an active oxide of iron or a sulphided active oxide of iron, the hydrogen-containing gases having an oxygen content sufficient to make the process thermally self-supporting. The oxygen content of the hydrogen content may be from 0.5-1.0% and the untreated gas is heated by heat exchange with the hot treated gas. The process is preferably carried out in an apparatus of the type shown in Fig. 2 in which the gas being treated flows countercurrently to a descending mass of contact material in a chamber 20. Fresh contact material is added continuously from a hopper 30 and spent contact material is withdrawn through a hopper 27. Specifications 567,231 and 583,809 are referred to.

Title: An electromagnetic brake for a motor
Inventor: MELINAND JEAN ALEXI
IPC: F16D65/18
Filed: 1991-03-26
Abstract: An electromagnetic brake for an electric motor (1) having a shaft (2) projecting from the motor casing (3), comprises a coil (4) coaxial with the shaft, and friction pads (5) mounted on a support (6) which is fixed on the shaft. The brake is mounted on the outside of the casing (3), and includes a cap (10) having bayonet-type or other fixing means (11 or 11') removably attachable on the casing. The cap encloses the coil and the support (6), together with a braking member (17) which is slidably mounted in the cap and biassed by a spring (18) which, through the braking member (17), when the coil is de-energised, forces the friction pads to be clamped between a braking surface on the base (16) of the cap and another braking surface formed on the braking member itself to arrest rotation of the shaft. Energisation of the electrical coil (4) moves the braking member against bias of spring (18) to release the brake. The invention is particularly applicable to lawn mower motors. <IMAGE>

Title: A method of mounting a mould system in a block stone moulding machine,and a correspondingly adapted moulding machine and mould system
Inventor: HANSEN HANS SPANGENBERG
IPC: B30B15/02
Filed: 1992-05-29
Abstract: In machines for moulding block stones a cellular mould (8) is used underneath a compacting head (12) having press plates (16) that can be pressed down for compressing the concrete mass in the moulding cells (10) and for pressing out the moulded stone members when the mould is raised. The mould (18) is fixed to lower carrier means (24) and the compacting head (12) to an overlying carrier head (6) in a mutually accurately centered manner, which requires high accuracies in the making of holes for the spanner bolts, while also the mounting of the compacting head is difficult to carry out. According to the invention the compacting head is directly precentered in the mould (12) by means of distance pieces (52), and the entire mould unit (8, 12) thus preassembled, is moved into the space between the carrier head (6) and the carrier means (24) for the mould (8), whereafter the mould (8) is secured to the carrier means. By the insertion of the mould unit into the said space a 'floating' engagement is established between co-acting holding portions (44, 46) at the lower side of the carrier head (6), and upon fixation of the mould (2) working cylinders (48) are actuated to pull up the holding portions (46) of the carrier head for clamping the compacting head in its centered position. Thereafter the distance pieces are removed and the machine is ready for operation. Thus, the compacting head will be very easy to mount, and generally very coarse tolerances can be used.

Title: Half wave resonator dielectric filter construction having self-shielding top and bottom surfaces
Inventor: AGAHI-KESHEH DARIOUSH
IPC: H01P11/00
Filed: 1992-03-24
Abstract: A dielectric block filter (100) construction having resonating cavities (126,134) formed therein to form one half wave-wavelength resonators thereby. The resonating cavities span opposing side surfaces (104, 106) of the dielectric block forming the dielectric block filter to define openings (142, 150) at the opposing side surfaces. Outer surfaces of the dielectric block, including the opposing side surfaces having the openings defined thereat, are coated with an electrically-conductive material except for portions of one side surface of the dielectric block about peripheral surfaces of input and output couplers (176, 182) formed on the one surface. Because the opposing outer surfaces are coated with the electrically-conductive material, the opposing outer surfaces of the dielectric block are self-shielding to prevent propagation of electromagnetic radiation through openings defined by the resonating cavities of the dielectric block. <IMAGE>
