Title: Elevator counterweight assembly with air deflectors
Inventor: YOO YOUNG S
IPC: B66B11/02
Filed: 1991-04-02
Abstract: Air deflectors 46 are mounted on the top and bottom of the counterweight assembly 2 in an elevator system to deflect air in the elevator hoistway to the sides of the counterweight as the latter moves up and down in the hoistway. The deflectors ensure that air turbulence is not directed toward the car as the car and counterweight pass each other in the hoistway. A quieter and smoother passenger ride is thus accomplished. In an ultra-high-speed elevator system, the counterweight assembly may be completely enclosed in an aerodynamic jacket (50, Fig. 4). Cable connections and compensating rope connections to the counterweight are preferably all made inboard thereof to ensure that the counterweight is free of turbulence-inducing protruberances. <IMAGE>

Filed: 1991-09-26
Abstract: There is disclosed a road gritter device (10) which forms a unit which can be mounted onto a loading platform (11) of a truck for use during the winter months, and which comprises a hopper body (12) assembled from a number of separately formed plates of rigid plastics material which are releasably coupled together for replacement when required. An endless conveyor (15) is arranged to convey gritter material from the hopper body (12) to a spinner disc assembly (13) which comprises a spinner disc (14) rotatable in a substantially horizontal plane in order to distribute laterally gritter material supplied thereto. The endless conveyor (15) has an endless conveyor band (16) made of plastics or elastomeric material, and preferably also the spinner disc (14) also is made of plastics material. Therefore, the major components of the road gritter device are made of plastics material which is not adversely affected by usual road gritter material incorporating "salt", which otherwise can cause serious corrosion damage to existing designs of gritter devices fabricated from metal sheet and having metal spinner discs. By making the hopper body of an assembly of separate rigid sheets or plates of plastics material, damaged or worn sheets can readily be replaced.
Patent GB-2255261-A (GB)
Title: Receiving data in a paging receiver
Inventor: YUN YOUNG-HAN
IPC: H04L1/00
Filed: 1991-10-21
Abstract: In a method for receiving and processing predetermined signals in a paging receiver with a battery saver function, a first (preamble) to third predetermined codes of a batch are detected. Then, if an error occurs in a second predetermined code (word synchronisation code) of a succeeding batch, rather than search for a second predetermined code of the succeeding batch, a BCH-decoding is performed continuously with code words (third predetermined codes) in the succeeding batch, by a BCH decoding algorithm. Thus, if a non-error code word is detected in the code words, the second predetermined code in which an error occurs previously can be recognized as the normal second predetermined code and a subsequent address code word is searched for. Accordingly, even if the second predetermined code is missed, at the normal batch construction, the missed second predetermined code can be compensated by the subsequent code word. <IMAGE>

Patent GB-2263578-A (GB)
Title: Mass spectrometers
Inventor: FRANZEN JOCHEN
IPC: H01J49/16
Filed: 1993-01-27
Abstract: A method for the mass-spectrometric examination of molecular ions from an ion beam, is characterized in that the energy distribution of the ions is reduced to a size suitable for mass spectrometry by slowing the ions by the co-current contact of the ions with a stream of a gas before mass-spectrometric analysis. As described the arrangement is particularly useful in analysing heavy organic ions which are produced with large average velocities of 5,000 metres per second either from thin foils 4 by laser-produced hypersound, as shown, or by matrix-assisted laser desorption, Fig. 2 (not shown). A light collision or friction gas, eg hydrogen or helium, is introduced at 5, 7 to form a gas jet travelling in the same direction as the ions, eg. at 2,000 metres per second. Both after and during slowing down in the friction gas the ions can be focussed by electrical guide fields and fed to the inlet of a mass spectrometer, preferably of the storage ICR type 18, or the RF quadrupole ion trap type, which enhance the temporal focussing. <IMAGE>

Title: Overload protection for a photomultiplier tube
Inventor: BUTLER NEAL R
IPC: H01J43/30
Filed: 1994-04-19
Abstract: A photomultiplier tube (12) is protected against overload by adjusting the voltage applied to a focus electrode (32) when an overload is detected. As shown, light source (10) illuminates the photomultiplier tube (12) which produces an output signal which is sent for example to photon counting electrodes (16). The photon counting electronics (16) provides an output (20) to a frequency to voltage convertor (22) which is used to modulate a high voltage amplifier including transistor (52) which controls the voltage applied to the focus electrode. When the photon counting electronics (16) indicate that the photons (10) produced by the photomultiplier tube (12) exceeds a predetermined maximum the high voltage amplifier reduces the gain of the photomultiplier tube (12). The photomultiplier tube may be of the venetian blind or microchannel plate type. Control in response to anode, dynode or electron multiplier current are also mentioned, as are control in response to the photocathode bias voltage, internal electrode voltage or focus electrode voltage. <IMAGE>
