Patent GB-2247484-A (GB)
Title: Road cutter
Inventor: LUPTON WILLIAM G
IPC: E01C23/09
Filed: 1991-08-07
Abstract: A cutter apparatus for cutting road surfaces (slitting or planing) is adapted to be carried by manipulating arms of a vehicle. The apparatus has a support wheel by which the apparatus can be loaded onto the road by the vehicle, and then can be rocked to bring the rotating cutter gradually into engagement with the ground. When the cutter has penetrated the ground the apparatus by the manipulating means is moved linearly to form a slit or channel. A linkage between the cutter and the manipulating means facilitates the manipulating operation. <IMAGE>

Title: Electrical connector assembly with self-cleaning action.
Inventor: THOMPSON RAY
IPC: H01R13/625
Filed: 1992-07-08
Abstract: An electrical connector assembly has a plug 1 and socket 2 which are engageable along axis 3 for a plug body 34 to be received within a socket body 4 as a tubular core 5 of the socket receives an optional core 35 of the plug. Spring terminals 13 are located within an annular cavity 7 and blade terminals 31 are located within an annular cavity 36 of the respective socket and plug bodies. Terminals 13 have cantilevered contact faces 18 inclined relative to the axis 3 and the terminals 31 have contact edges 52 which slide over the contact faces 18 to provide electrical contact and a cleaning/wiping action therebetween. Contact faces 18 are displaced inwardly against their resilient biasing by engagement with the contact edges 52 while the terminals 31 are restrained from outward displacement by seatings 42 in the wall 34. Alternatively, the spring terminals 13 are reversed to be displaced outwardly by blade terminals 31 restrained from inward displacement by core 35. The spring terminals 13 and blade terminals 31 are fitted axially to their respective bodies through slots 11 and 38 respectively. The terminals 13 and 31 terminate axially short of leading ends 8 and 37 and the annular cavities 7 and 36 may ensure that the terminals are inaccessible to a standard test finger. A bayonet lock ring 32 may be provided between the plug and socket, to provide increased torque at the completely locked and unlocked positions. <IMAGE>

Title: Apparatus for heating liquid
Inventor: LITTLE PETER JAMES
IPC: A47J27/21
Filed: 1992-08-13
Abstract: A vessel (1) contains liquid heated by a liquid heating portion (4) which is an electrically heated substrate constituting an integral part of the vessel. A heater element (7) formed on the substrate comprises a resistive track receiving power from a power control circuit. Temperature sensors (10,13) are provided on the substrate in the form of resistive tracks and a temperature sensing circuit is arranged to turn off the power in response to an increase in temperature of a part of the substrate. Overheating of the heater element is thereby avoided when the vessel is tilted such that part of the liquid heating portion is exposed above the liquid level. <IMAGE>

Title: Coding method for broadcast transmissions
Inventor: CHAMBERS JOHN PHILIP
IPC: H04L27/32
Filed: 1992-11-02
Abstract: A broadcast transmission using a frequency-division multiplex technique, such as the so-called DAB or DSB proposed radio system, uses a large number of carriers generated by coding digital information using a fast Fourier transform (12). Additional data is carried by relatively varying the amplitudes of the carriers in a modification circuit (26) by a slight amount in accordance with the additional data. The additional data may comprise transmitter identification. The additional data can be recovered by decision logic (46) in a receiver.

Title: Linear vibratory conveyors.
Inventor: PROBERT ALBERT RONALD
IPC: B65G27/32
Filed: 1992-11-23
Abstract: A system of two mechanisms working in concert on the conveying tray 1 of any type of linear vibratory conveyor however it is driven to improve its conveying action and achieve satisfactory operation of much longer conveying trays. The first mechanism is illustrated in Figure 1 and consists of an extension piece mass 3 to absorb whiplash and rotational forces which would otherwise set up undesirable directions of movement on parts of the conveying tray especially if it is long. The second mechanism is illustrated by way of example in Figure 4 and consists of springs or tension rods 7 which constrain the tray movement to that which provides efficient transportation of material and which springs may also be used to fine tune the vibrator to the required operating frequency. <IMAGE>

Title: Digital class receiver using most liklihood estimation
Inventor: TULAI ALEXANDER F
IPC: H04L27/156
Filed: 1993-05-07
Abstract: A class message receiver that in one embodiment can be implemented in a Digital Signal Processor. An FSK demodulator takes input linear samples (9) of the signal and filters them with a bandpass filter (11) which does an upsampling to increase the sampling rate from 8,000 Hz to 24,000 Hz, which results in 20 samples at the output of the bandpass filter for each incoming data bit. The amplitude of the signal/samples at the output of the bandpass filter is adjusted by an automatic gain control (AGC) circuit (12) and the resulting samples (for convenience referred as sample (t), where t is a discrete moment in time) are processed along two different paths designed to estimate the likelihood of the input signal encoding a mark (mark estimation path) or a space (space estimation path). <IMAGE>

Title: Cable guide for a terminal crimping apparatus
Inventor: NITTA YOSHIO
IPC: H01R43/052
Filed: 1994-02-08
Abstract: A cable guide for a terminal crimping apparatus includes a guide member 40 held between support plates 41a, 41b in a clamped state such that one end of the guide member 40 is turnably supported while the other end of the guide member is normally biased in the upward direction by the resilient force of a coil spring 44. A cable is inserted through a nozzle 32 and a slit 45b1 formed through the fore end part of a restricting piece 45. As an arm 31 is turned to assume a horizontal attitude, the nozzle and the restricting piece are displaced toward a cable guide 40 together with the arm. Thus, the cable is displaced to an optimum cable feeding position relative to an applicator while slidably moving along the upper surface of the guide member. Since the plate-shaped guide member serves to properly guide the displacement of the cable, the terminal is always securely crimped and the cable is prevented from being undesirably deformed. <IMAGE>
