Title: Plastics ski filled with expanded foam - has glass balls on inside of wall panels to increase shear strength between foam and wall panels
Inventor: SCHMITZ WIDO F
IPC: A63C5/12
Filed: 1976-10-22
Abstract: The ski that is made from plastics, has four high density plastic panels (1-4) which form the outer walls of the ski. The internal space which is enclosed by the wall panels, is filled with expanded plastic foam. In order to increase the shear strength of the boundary layer between the expanded plastic foam and the wall panels, tiny glass balls are bonded to the inside of all wall panels. A permanent elastic adhesive is used to attach the glass balls to the wall panels, thus the elasticity of the ski is maintained within an acceptable range of bending.

Title: Decorative panel for doors or table-tops - is made from metal foil cut into squares and coated with paint or lacquer
Inventor: O'REILLY EDGAR
IPC: B44C1/24
Filed: 1977-03-23
Abstract: The surfaces of door panels or table-tops can be decorated very cheaply by using a sheet of metal foil (3) which is bonded to the wooden undersurface (1) with a layer of adhesive (4). After the foil has been placed in position the sheet is cut into a number of small squares (2) with turned down edges (5) which are pressed into the wooden surface. If required, the squares can be pushed close together before the adhesive has hardened. The panels can then be painted with the paint filling the grooves formed between the edges of the panels by the turned down edges. The paint can then be covered with a coat of lacquer.

Title: Sequence controller for computer processing unit - has clock generator and serially connected instruction registers with associated decoders
Inventor: LYNCH JUN DAVID D
IPC: G06F9/28
Filed: 1977-04-20
Abstract: A sequence control for the processing unit of a synchronously operating computer housing a clock generator and several instruction and data processing paths is designed to enable simultaneous processing of several instructions. This permits the computer operating speed to be increased and enables large quantities of data to be processed in real time. An instruction path contains a chain of instruction registers each associated with a stage of the path and through which the instructions pass under clock pulse control. Each register is associated with a decoder which identifies the instruction from the operating code to produce control signals which control the associated stages of the data path. The data path input stages contain several independent data inputs.

Title: Two=way elastic, frictional, foundation garment fabric - is of tulle fabric produced on a Raschel loom and has an edge zone half the thickness of remainder
Inventor: WISCHER MARTIN
IPC: D04B21/18
Filed: 1977-06-01
Abstract: An elastic tulle fabric produced on a Raschel loom, esp. for foundation underwear e.g. panties, has intermeshed webs or warp threads. The first web or warp threads is basically of material without elasticity, whilst the second set of warp threads has a high degree of elasticity. There is also a web of weft threads of elastic material, and in at least one section there is laid in, an additional web of warp threads having a high cofftnt. of friction. At least in this latter section with the additional warp threads the second elastic warp threads are thinner than in the rest of the fabric. Whilst maintaining the advantages of frictional zones which prevent the rucking, creasing and sliding of the garment, it is possible to make a fabric surface of much improved appearance on the outside.
Patent DE-2729352-A1 (DE)
Title: Electronic strip detector adjusting equipment - has detector transmitting reflected light as voltage to switching circuit
Inventor: WAHL GUENTER ING GRAD
IPC: B65H23/02
Filed: 1977-06-29
Abstract: The equipment adjusts an optical electronic detector monitoring a travelling strip of material, partic. one with embroidered flowers, along a contrast line or a deeper guide line. It comprises a light emitter and a receiver measuring the light reflected from the strip and controlling the strip movement. A detector (10) reacts to the contrast line (4) in the travel direction between two areas (4, 5) having different degrees of reflection, and transmits the intensity of the reflected light as a voltage to a switching circuit. This converts (20) voltage variations from an adjustable desired value, resulting from sideways movement of the contrast line, into setting impulses for the adjusters. A hand control (30) for the latter adjusts the circuit, so that when starting the monitoring operation either the detector or the strip (2) is brought into the desired position, giving a desired voltage in the circuit.

Title: Throat gas cleaning plant for pressurised blast furnace - where turbine recovering energy is located upstream of gas washer
Inventor: HEGEMANN KARL-RUDOLF ING GRAD
IPC: C21B7/22
Filed: 1977-08-19

Patent DE-2746154-A1 (DE)
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/215
Filed: 1977-10-14
Abstract: A quartz crystal tuning fork vibrator comprises a monolithic quartz crystal vibrator having a tuning fork shape with a plurality of vibratable tines. A set of electrodes are adhered to opposite surfaces of the tuning fork vibrator and are arranged in such a manner that when suitable alternating voltage is applied thereto, the tines undergo flexural vibration in their fundamental or resonance mode. The electrodes on each tine surface are preferably arranged in groups of four with the center two being applied with voltage of one polarity when the outer two are applied with voltage of the other polarity thereby establishing electric fields within the tines at the outside portions thereof while no electric field is established at the center portion of the tines. All of the flexural strain is thus confined to the outside portions of the tines thereby lowering the amplitude of vibration of the tine ends to the order of 5 mu -10 mu .

Title: Seat valve for water or emulsions - has valve member with lower bulbous head for throttle opening at start of lift
Inventor: HAERTWIG MANFRED
IPC: F16K17/02
Filed: 1978-04-19
Abstract: The seat valve for water or oil and water emulsions has an upper chamber housing a spring between two flanges, the lower flange (13) resting against the stem (7a) of the valve member (7). The stem carries a disc portion with a face (7b) having a raised area (7c) which so lifted from the raised rim (3a) of a shaped ring (3) against the force of the spring to allow the liquid to pass upwards and sideways through the side outlet through a side part (6d). Below the disc portion is a bulbous head portion (7f) acting as a throttling member inside a chamber (20) in the lower part of the shaped ring (3). The cylindrical part forming the largest diameter of the bulbous head has a lower corner (7g) which is first lifted from a sharp corner (3g) of the ring forming the throttling opening.

Title: Mould for shaping an integral beaded sleeve and plastics pipe - incorporates aligned core, composite forming ring and bushing, to avoid re-softening and final deformation prod. after removal from tool
Inventor: NEUEDER LUDWIG
IPC: B29C45/26
Filed: 1978-04-19
Abstract: In a device for mfg. thermoplastics tubes or pipes with beaded sleeve, the shaping of the initial, plain pipe whose (intended) sleeve section near the end gradually passes into a cylindrical section of relatively greater dia., is effected by heating at least the leading section and radial constriction of the pipe. The injection-mould used incorporates a bushing upon the mould core, and a shaping ring which is divided into segments and has the outer contours of the constriction. Both the bushing and the ring are coaxial with the mould and radially movable w.r.t. the core. They are displaced after injection of the moulding cpd. by moving the bushing axially away from the moulding, the ring segments radially towards the core and shaping ring axially towards the moulding. Shaping of the constriction is effected inside the mould whilst the moulding is still hot, thus dispensing with reheating and re-shaping after removal from the mould.
