Patent GB-2032037-A (GB)
Title: A frame and panel arrangement
IPC: B23Q11/08
Filed: 1979-07-12
Abstract: A frame and panel arrangement particularly for cabinets to contain machinery, wherein a panel (3) of resilient material has at least one of its edges folded over to form a flange (13) extending at an acute angle to the plane of the main portion (8) of the panel (3) and the frame has a member (4) spaced inwardly from an outer member (1) to form a gap of lesser width than the spacing of the free edge of the flange (13) from the main portion (8). When the edge of the panel is pushed, by sliding the panel (3), into the gap, the resilience of the flange (13) secures that edge of the panel (3) with respect to the frame. A further similar flange (11) may be provided on another, preferably opposite, edge of the panel (3) to co- operate with a further member (5) of the frame (1) and be retained by a spigot (7) and aperture (10) arrangement when the panel (3) is slid downwardly. <IMAGE>

Title: Varactor tuned oscillator circuits
IPC: H03B1/00
Filed: 1978-12-05
Abstract: An oscillator circuit (Figure 2) has a varactor diode 4 for setting its frequency of oscillation. A limiter 5 limits the amplitude of oscillations of the circuit so the diode never becomes conductive allowing a capacitor C to be used to integrate a tuning current so the oscillator can be tuned according to the charge on the capacitor. A control system (Figure 3) using the charge tuned oscillator has two loops Figures A and B. A coarse control loop Figure 3A changes the capacitor until the oscillator frequency is approximately equal to a reference frequency. The other loop Figure 3B uses an operational transconductance amplifier OTA to charge and discharge the capacitor to more finely adjust the oscillator frequency. <IMAGE>

Title: Command Buffer for Cache Memory
IPC: G06F12/08
Filed: 1978-12-14
Abstract: Apparatus and method for providing a buffer stage, or cache memory command circuit, between a cache memory unit and a main memory unit. The transfer of data between a main memory unit and a cache memory unit can be complicated because the circuits utilized in the cache memory unit and/or the main memory unit in effectuating the data transfer can be pre-empted. In addition, the data transfers must be executed in sequential order. According to the present invention, the transfer of data is divided into two portions, a portion involving cache memory unit and a portion involving the main memory unit along with associated interface units. The cache memory unit stores the data transfer commands and the associated data in sequential order (in 220, 230). The cache memory unit and the main memory and interface units can execute their respective portions of the data transfer independently permitting overlapped instruction execution. The cache command buffer insures that the operations involving the two units of the data processing unit are executed in sequence. When data transfer has been completed, the cache command circuit continues to the execution of the next data transfer in sequence. <IMAGE>

Title: Feeding extruders with hot continuous strip
IPC: B29C48/03
Filed: 1979-07-24
Abstract: The output of a screw extruder is maintained constant by automatically varying the feed rate of a hot continuous (rubber) strip (8) to the extruder, to maintain constant the location (c) at which the rubber is consolidated i.e. at which the screw flight is filled, by maintaining constant the minimum cyclic pressure (P1) sensed by an extruder barrel pressure sensor S1. Preferably, a sequential pair of pressure sensors (S1, S2) are linked to a control means (15) for the feed rate, which acts by comparing differences between the minimum cyclic pressures (P1 and P2) sensed by the sensors (S1 and S2), and extrapolates to determine the location of consolidation, thereby eliminating pressure changes due only to temperature or viscosity changes in the rubber. The sensor (S1) is preferably located at least one flight pitch from the end of the barrel. The control means (15) may vary the feed rate of mill which forms the strip, or preferably the rate at which feed rollers 12 feed the strip, with an intermediate loop (11) of the strip being automatically maintained between sensors (13, 14) by altering the strip thickness or width e.g. by knives (10). The extruder screw may be of constant or varying volume along its length. <IMAGE>
