Patent GB-653387-A (GB)
Abstract: 653,387. Guillotine cutting-machines. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD, V. W. May 5, 1947, No. 12093. [Class 31 (i)] In a guillotine cutter comprising a fixed and a movable blade the movable blade is mounted in a carrier having bearing pockets in which opposite ends of a holder for the movable blade are supported, the opposite ends of the carrier being mounted to enable the blade to give a combined downward and transverse sliding movement during the cutting stroke, and the movable blade being supported on the carrier by adjustable spring means urging the blade toward the fixed blade. The movable blade may be operated either by hand with a return spring or mechanically. As shown, the movable blade 6 is secured by screws to the holder 6a of square cross-section. The ends of the holder 6a are mounted in the bearing pockets 8 in the carrier 7. Alternatively the blade and holder may be replaced by a one-piece blade having squared ends engaging the pockets. Longitudinal movement of the blade and holder is prevented by abutment of the blade on the pockets. Forward movement of the holder 6a is limited at one end by a plate having an adjusting screw 13a. The blade 6 and holder 6a is engaged by a number of spring-loaded plungers 9, each spring 12 abutting a cap 11 in screw-threaded engagement with a casing 10. One end of the carrier 7 has a depending lug 16 having a slot 17 engaging a pin 15 on a base 5 on which is mounted the fixed blade 4, which is always overlapped adjacent the pin 15 by the blade 6 and at the other end of the carrier is a lug 18 having a slot 19 at an angle to the horizontal in which runs a pin 20 secured to the base 5 so as to give the movable blade a slicing and scissor action in co-operation with the fixed blade.

Title: Treating filter materials
IPC: B01D39/16
Filed: 1978-07-18
Abstract: The invention provides apparatus for treatment of filter materials for use in dust proof masks or the like. With such filter material it is important that the dust collecting efficiency is enhanced and that its resistance to its gas/air penetration is reduced as much as possible to make breathing easier by the wearer. The invention is characterized by the apparatus comprising at least one pair of carding rolls, each roll having cone or pyramid like protrusions 7 formed regularly over its surface and the said rolls providing a gap which is adjustable in relation to the thickness of a filter material web 8 passed therethrough, whereby the tips of said protrusions act on the material to make it fluffy for improved dust collecting efficiency and to reduce resistance to gas penetration. <IMAGE>

Title: Magneto-Optical Phase- Modulating Devices
IPC: G01C19/68
Filed: 1978-09-23
Abstract: The reflectivity at the surface of a magneto-optic layer of garnet (bismuth doped, or praseodymium) or orthoferrite material intended to provide phase modulation in a ring laser gyroscope system is modified by an adjacent dielectric layer or stack of dielectric layers, e.g. alternately ZnS & MgF2. For use as a transverse Ker magneto-optic effect mirror forming part of the laser ring the layer(s) provide increased reflection; for use as a Faraday effect element between two mirrors of the laser ring the layer(s) act as anti-reflection components. In either case the magneto-optic layer may lie directly on a transparent substrate provided on its opposite surface with anti-reflection layer(s), or preferably the substrate may have deposited therein in turn the reflectivity modifying layer(s), the magneto-optic layer, and further anti- reflection layer(s). In the Faraday effect device shown, anti-reflection stacks 5, 7 and 8 are provided on either side of, and between, substrate 2 and magneto-optic layer 1. <IMAGE>

Title: Apparatus for collecting a surface layer of liquid
IPC: B01D17/02
Filed: 1978-11-13
Abstract: Apparatus for collecting a surface layer on a body of liquid, e.g. a layer of oil on water, comprises a member (1) defining a central passage (2) which is upwardly open and is arranged in use with the opening at the level of the interface between the surface layer of liquid and the underlying layer, and a member (3) which defines an annular passage with member (1) provided with vanes (8) which form the rotor of an axial pump when the members (1, 3) are rotated about the axis of the passage (2). This rotation causes the layer of liquid underlying the surface layer to be drawn towards the apparatus and downwardly around the passage (2) to draw the surface layer of liquid into the passage (2). Pump 15 conveys liquid from passage (2) to a reservoir. Members (1, 3) may be rotated by pneumatic turbine (9). <IMAGE>

Title: Determination of radiation absorption in a cross section of a body
IPC: G01N23/083
Filed: 1979-01-08
Abstract: A computed tomography arrangement using a polychromatic source can give rise to errors in image reconstruction due to the effect of beam hardening. In the improved method, the normalised spectral intensity Ti and the energy Ei relating to the spectral distribution of the source, are determined and stored 4. The length L of each measurement path lying within the body, and the corresponding detector measurement value I are also stored 2, 1. To compute a sectional image in 12, the usual measurement value I is replaced by a computed value A1 representing the absorbed part of the radiation, or by a value   <IMAGE>  which also accounts for radiation lost by Compton scattering. For each value I, successive test values A1 are applied from a data store 3 to a computing stage 5 which evaluates   <IMAGE> where A2 =a2L (a2 is a constant value for example in the range 0.15cm<-1></=a2</=0.18cm<-1>), n  APPROX  3, and f(E1) is a factor dependent on Compton scattering. A comparator 7 senses either I=Î and feeds the value A1 directly to a store (9), or determines the adjacent values Îa> I(for A1a) and Îb <I (for A1b) which are stored 6 and provide the final value for A1 by interpolation in computing stage 8. The corresponding value P is computed by 10 and stored 11 with values relating to other measurement paths prior to image computation in 12. <IMAGE>

Title: Recording apparatus
IPC: G11B20/08
Filed: 1979-05-29
Abstract: Tape recording device in which a voltage level (Vx) at 15 is compared at 16 with a saw tooth time base signal to produce a square wave signal (C) for recording. The reading derives an output which is proportional to the ratio of the mark length (T1) to the wavelength (T2) of the square wave (C) which is thus independent of slow variations in tape drive speed, enabling use of a single tape drive. <IMAGE>

Title: Slow motion or still picture video reproduction system
IPC: G11B5/53
Filed: 1979-07-27
Abstract: The system comprises a tape 18 on which are recorded a video signal along oblique contiguous bands and a control signal longitudinally along the tape. Rotating heads 13a, 13b for reproducing from the video tracks have mutually different azimuth angles respectively equal to those of the recording heads and are at different heights above the plane of rotation of the centres of the tracks in the width direction thereof. Means 27 supply the control signal to units 47, 49 for delaying the reproduced control signal for controlling stopping of the tape 18. The tape 18 is thus stopped in relation to the video heads 16a, 16b at a position such that the minimum level of the reproduced video signal occurs within or in the vicinity of the vertical blanking period. <IMAGE>

Patent GB-2031622-A (GB)
Title: Voltage regulators
IPC: G05F1/38
Filed: 1979-09-13
Abstract: A voltage regulator, applicable to A.C. rectifiers in which each diode 7 in the rectifier is connected in series with a choke coil 3 which is saturated by the load current, includes on each of the choke coil cores a second coil 5 fed by a direct control current 6 magnetising the cores. The value of the back-emf in the load coil on the passage of each half wave is a function of the value of the permanent control magnetisation, and thus the output voltage is a function of the direct control current. There may be only a single diode, but preferably there are four or six as in a full-wave single or three phase rectifier, the control coils then being connected in series to the control current source in order to correct any imbalance in the phases. <IMAGE>
