Patent GB-859038-A (GB)
Title: A.c. to d.c. power supply variable as to polarity and magnitude
IPC: H02P7/292
Filed: 1959-03-23
Abstract: 859,038. Control of D.C. motors. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION]. March 23, 1959 [April 14, 1958], No. 9999/59. Class 38 (3). [Also in Group XXXIX] A reversible D.C. motor RM is energized from an A.C. supply 9 through a magnetic amplifier comprising two saturable cores 3, 4 each provided with a power output winding 3g, 4g, a reset winding 3r, 4r and a D.C. control winding 3c, 4c, the power output windings being connected in separate parallel paths which include respective rectifiers 5, 6 and voltage bias means 7, 8. Each rectifier is connected so that its conductive direction is opposed to the associated voltage bias means, and the respective conductive directions in the two paths are related to opposite half-cycles of the A.C. supply. In the absence of a control signal from a source 10, both power output windings are equally conductive and a symmetrical alternating current is applied without effect to the motor. As both reset windings 3r, 4r are connected to the A.C. source, an alternating reset current is established which resets the flux of the saturable core not operative in a given half-cycle and assists the change of flux to saturation in the saturable core operative at that time. When a control signal is applied to the control windings, however, one core is saturated earlier in a respective half-cycle than the other core, and an asymmetric alternating-current output is applied to the motor, the D.C. component of which determines the direction of rotation, according to the control signal polarity. The voltage bias means 7 and 8 are provided to neutralize the effect of the back E.M.F. developed across the motor, since this voltage would otherwise tend to maintain one rectifier conductive during the inoperative half-cycle of its respective parallel path and so adversely effect the flux resetting action. The voltage bias means may be either batteries, Fig. 2 (not shown), or Zener diodes, Fig. 3 (not shown). A modification is described, Fig. 4, in which a further saturable reactor 20 has its power output winding 20a connected between the magnetic amplifier and the motor, and has a control winding 20b connected across the motor terminals. In the absence of a control signal at the magnetic amplifier, the winding 20a presents a high impedance which limits the output of symmetrical alternating current. If, on the other hand, the motor is driven by an asymmetric current, the back E.M.F. across the motor acts through winding 206 and saturates the reactor.

Title: High-strength sandwich-structure carbon respectively kevlar fibre reinforced plastic structural element particularly for medical use for radiography diagnostic respectively ray therapy purposes
Inventor: LENGYEL LASZLO
IPC: B32B5/18
Filed: 1986-10-07
Abstract: A high strength structural component of sandwich type construction is proposed. Based on carbon or kevlar fibre reinforced plastic, mainly for medical use (X-ray diagnostics or radiation therapy). - The structural component is in sheet form and has low resistance to high energy radiation. Cross section of the sheet is formed by large radius arcs at the top and small radius arcs at the bottom radiation absorption of this cross section is within acceptable limits. Also, absorption changes gradually with changing direction of incident radiation. - The materials used for the sheet are in line with up-to-date practice, except for the epoxy resin used as a matrix for the matrix an unsatd. polyester resin mix is used, with low viscosity, so that it wets the foam used as the core material and hence takes more of the load, so that the number of covering layers may be reduced. - To prepare the sheet a) the core is formed by cutting from a sheet of hard foam or forming the foam directly in the tool, b) the reinforcement is woven material of carbon or kevlar fibre which is fixed to the core by burning its own material c) the core is then put in a tool of suitable dimensions d) a vacuum is formed within the tool and the resin impregnates the core, and e) surface coating can be carried out during manufacture by adding the covering layer to the tool before the operation, or afterwards.

Title: Method for producing high-strength, dimensionally stable structural material
Inventor: MAYER LASZLO
IPC: D04H3/12
Filed: 1988-08-31
Abstract: The proposed material is produced using natural and/or man-made fibres and thermoplastic threads formed into a mat by carding and consolidated by the application of pressure and heat. The mat with the low melting point, thermoplastic, pref. poly-ethylene or poly-propylene, threads is worked by two or more carding machines to form a non-homogenous structure, with the highest concentration of low melting point threads in the top layer. The mat is then moved to a drying cabinet and the polymer threads are cut up by a hot air jet. The mat is then pressed and cut to size, or in some cases heated using infra-red radiation at approx. 140 deg. C. A decorative layer is added using a binder material and pressure. Alternatively the correctly sized mat is shaped in a press-tool
