Patent GB-2098108-A (GB)
Title: Sharpening method and apparatus for rotary cutting wheel
IPC: B26D7/12
Filed: 1982-04-26
Abstract: A sharpener for a rotary cutting wheel includes an abrasive wheel that rotates about an axis disposed in non- parallel relationship with the axis of rotation of the cutting wheel. The end face of the abrasive wheel rubs against one side of the cutting wheel and across the peripheral cutting edge with rotary motion so that a whetting motion is simulated. The abrasive wheel may be free wheeling and pressed into engagement with the cutting wheel so that driving forces on the sharpening wheel cause sharpening of the cutting edge to occur simultaneously with rotation of the cutting wheel in a cutting operation. Alternatively, the abrasive wheel is motor driven and moved in and out of contact with the cutting wheel for sharpening the cutting wheel independently of a cutting operation.

Title: A signal processing system
IPC: G06F17/40
Filed: 1982-05-04
Abstract: The invention relates to the  provision of an analogue signal processing arrangement for use with a micro-computer. The host microcomputer is provided with a signal  processing hardware board SPHB   which is connected to the address and data buses of the host microcomputer. The hardware board   consists of a signal processing program store SPPS, a board control  logic CL and a number of analogue  signal handling channels CH 1-4.  Each channel (see Fig. 3) includes a  programmable timer, a counter, a   random access memory, an input path including an analogue-to-digital converter and an output path including a digital-to-analogue converter. The hardware board SPHB is controlled by the host microcomputer so that the memory in a channel is used to store waveform samples generated by the host microcomputer or the input path for presentation to the host microcomputer or the output path as required. In addition the program store SPPS is adapted to hold machine- code signal processing programs executed by a call from the host micro-computer. <IMAGE>

Title: Activated sludge process
Inventor: CHAMBERS BRIAN
IPC: C02F3/12
Filed: 1984-01-30
Abstract: In the activated sludge treatment of aqueous effluent, the effluent is aerated first by one or more mechanical aerators introducing air into the surface of the effluent, and then by one or more submerged diffusers. In this way, biofouling of the submerged diffusers (eg. fine bubble diffusers) is avoided, and also a higher efficiency in terms of mass of oxygen absorbed per unit of energy input is achieved than with either a mechanical aerator system alone or a submerged diffuser system alone. Preferably 20% to 50% of the total oxygen demand is satisfied by the mechanical aerators. <IMAGE>

Title: Inverter circuit arrangement
Inventor: HOULDSWORTH JOHN AUSTIN
IPC: H02M3/337
Filed: 1984-06-29
Abstract: An inverter comprises a pair of circuits (suffixed A and B respectively) each comprising a transformer 3 a primary winding 17 of which is connected with alternating polarity across input terminals 1, 2 via a choke 7 by means of a pair of switches 8, 9 (such as FET's Fig. 5) for periods equal to one-half the period of the resonant frequency of the resonant circuit comprising the transformer primary winding 17 and a capacitor 16 connected across it. The resonant frequency is the same for both circuits. To control the voltage across output terminals 4, 5 in spite of the constant-current properties of the chokes the transformers have a common secondary winding 18 and the phase of the antiphase switching signals applied to the switches of one circuit is made variable with respect to the phase of the antiphase switching signals applied to the switches of the other circuit by varying a control signal 13 applied to a switching signal generator 12, thereby varying the relative phases of the signals (V1, V2 Figs. 2a, 2b, 2c) contributing to the voltage (44, 37, 40) across the secondary winding. The transformers may have completely separate magnetic circuits or their magnetic circuits may have a portion in common, on which portion the secondary winding is provided. <IMAGE>

Title: Magneto-optical device
Inventor: VOLZ HANS
IPC: G02F1/095
Filed: 1984-12-12
Abstract: An optical arrangement includes a light source (20, 21) emitting polarized light, an analyzer (22), a component (10) containing a thin layer of ferromagnet amorphous metal whose optical properties can be varied by a magnetic field located between the light source and the analyzer, and a preferred direction of magnetization impressed on the magnetic layer. The magnetic layer mates an oblique angle with the direction of light propagation. The magnetic field which is impressed on the magnetic layer and whose direction can be changed by an external magnetic field changes the plane of polarization of light passing through the layer. A coil (13a, 13b) surrounding the magnetic layer and deposited by thin-film techniques turns the optical component into a light switch, and the optical arrangement containing the optical component into a transmitter of amplitude-modulated light. <IMAGE>

Title: Security containers or enclosures
Inventor: TORLESSE ARTHUR TIMOTHY
IPC: B65D55/02
Filed: 1985-07-24
Abstract: A security system for detecting tampering with or entry into containers or enclosures comprises a container 1 in which a part of the surface of the container 1 is coated with a paint 3 having magnetic particles associated therewith. The paint 3 covers the boundary between the container 1 and a panel 2 of the container. If an attempt is made to gain access to the container 1 by removal of the panel 2, the magnetic particles, which due to the fact that the paint 3 has dried are fixed into a stable pattern, are disturbed and so the pattern is changed. By initially recording the pattern of magnetic particles immediately after the paint has set, and then subsequently inspecting and comparing the initially recorded pattern it is possible to determine whether or not the container 1 has been tampered with or entered into. <IMAGE>

Title: Fuel control system
Inventor: GRAVESTOCK ROBERT EDWIN
IPC: F02D41/36
Filed: 1985-09-30
Abstract: A fuel control system for the fuel supply system of a compression ignition engine is arranged so that above a predetermined engine speed and below a predetermined level of fuel supply, fuel supply to the combustion chambers of the engine in turn is prevented. The remaining combustion chambers are arranged to receive an increased fuel supply to maintain the engine power. An engine or pump speed signal from a transducer 21 is compared in comparator 20 with a reference signal from a source 22 and gives an output to AND-gate 23 when the speed is above the predetermined value. Similarly the AND-gate 23 is provided with a signal by a comparator 24 when a fuel demand level detected by a transducer 25 exceeds a level set by a reference source 26. The output of the AND- gate is used to actuate a switching circuit 27 to actuate electromagnetic valve(s) 19, Fig. 1, via circuitry 27-36 to control injection valves 10-13, Fig. 1. <IMAGE>
