Patent NL-297060-A (NL)
IPC: G11C11/44
Abstract: 1,023,462. Circuits employing super-conductors. RADIO CORPORATION OF AMERICA. July 31, 1963 [Aug. 24, 1962], No. 30426/63. Heading H3B. [Also in Division H1] A super-conducting circuit for selecting the input to a three dimensional storage matrix comprises a large number of tree circuits, and one or two control elements for each set of corresponding tree branches so arranged that if the control elements are driven out of their super-conductive state all the corresponding branches are no longer magnetically shielded and therefore have a high inductance. As shown in Fig. 6, when control films such as 1-4 and n-4 are driven resistive by current applied at 114 they allow magnetic flux to pass through them and the tree branches 1c, 2c . . . nc have a high inductance. Thus by applying current to appropriate conductors 112,151, 153, 120 it also can be arranged for there to be only 1 low inductance path through each tree. To improve the switching rate of the control areas they may have a resistor connected in parallel of lower value than the resistive value of the film. In this way the film itself takes only sufficient current to drive it resistive (Fig. 4, not shown). The control areas may when super-conductive, shield the conductors from high permeability materials. The conductors and memory planes are preferably insulated with silicon monoxide. The high permeability materials should have little hysteresis at the operating temperatures but this is stated to include most ferrites and other normally square loop materials owing to the low operating temperatures. The use of only two control elements rather than one for each tree is stated to improve the switching speed. Lead and indium may be used as the super-conducting materials. The control elements may be changed from the super-conducting state by means of magnetic thermal, radiative or mechanical energy if desired.

Title: Mould with wall sections traversing in stages for
IPC: B27N5/02
Filed: 1968-07-30
Abstract: Moulding of articles where the end of the moulding is not the region of greatest cross-sectional area. The mould is constructed with mobile wall sections which can retract sufficiently to allow the moulding to be removed. The wall sections then advance to an intermediate position which leaves the appropriate volume for the necessary quantity of the resin feedstock for the moulding prior to compression. After filling the mould cavity, the wall sections advance to the distance from the opposite mould wall or the mould core which defines the final thickness of the moulding. The various mould wall movements may be achieved by a series of single action rams used in turn or by a double action ram subject to suitable traverse stops. Pref. the mould surface is defined by an interchangeable insert and the mould wall travel is adjustable to suit different moulding if necessary.

Title: Determining emission coefft. of radiant body - measuring IR radiation reflected from surface by parabolic mirrors and focussed via interference filter and diffusor
IPC: G01J5/00
Filed: 1987-06-25
Abstract: A beam of infra-red from a laser (1) is directed at the surface of the body under investigation (5), via an optical modulator or chopper (2) and a plano-convex lens (3). The chopper operates at a frequency of about 60 Hz. The radiation reflected from the surface is re-reflected twice by two off-axis parabolic mirrors (6,7). The resultant focussed beam passes through an interference filter (8) and a diffusion plate (9) and is detected by a pyro-sensitive transducer (1O) at the focal point. The transducer output is then fed via a bandpass filter (11) to the measuring signal processor (12). A second transducer (4) detects radiation reflected from the rear of the plano-convex lens (3). The output of the second transducer (4) provides a reference level against which the signal reflected from the body can be measured.

Abstract: The mechanism lifts, lowers and tilts the load platform, tapering in the lengthwise direction, of a goods vehicle, having ram-operated lifting arms, together with hydraulic closing arms. Each lifting ram (11) has a cylinder with oil chamber connected to the pressure pump and connected to a second cylinder in which a disc (18) with rod (18') moves axially under the effect of the oil pressure.

Abstract: A caulking gun and cartridge combination is provided with afterflow prevention. The cartridge has a tubular body (8), a forward dispensing opening (9) at a forward end of the tubular body, and a backwall (11, 12) movably disposed within the tubular body (8). The caulking gun has a trough (1) for receiving the cartridge, and a piston (4) movable parallel to the trough (1). A trigger handle (23) is used for pushing the backwall (11) forward within the tubular body and causing a reduction of volume within the chamber (13) in the cartridge. The backwall slides substantially in a contact-less manner within the tubular body, preferebly by way of a reduced diameter (OD) of the backwall (11) relative the inner diameter (ID) of the tubular body (8), so that it is pushed backwardly when the body retracts radially after actuation. Alternatively, the cartridge body may be prevented from expanding or may even be actively squeezed so that afterflow caused by the volume reduction of the relaxing tube body is safely prevented.
