Title: Multiwalled tubes mfr. by cold drawing - using die to reduce outside dia., or mandrel to expand bore
Inventor: HUNGER WALTER
IPC: B21C37/15
Filed: 1979-05-16
Abstract: Multiwalled tube can be made from two co-axial tubes which are then subjected to cold drawing. The cold drawing is achieved in two ways. In the first method the assembled tubes (2, 3) are drawn through a die (4) which reduces the outside dia. and presses the outer tube (3) against the inner (2). The second method uses a mandrel which expands the bore of the inner tube. In both cases a firm bond is achieved between the two tubes more easily than by forcing one tube inside another with an interference fit.

Title: Sawing machine automatic timber aligning mechanism - has paired aligning unit stops permitting movement one way, but permitting alignment in opposite direction
IPC: B27B31/06
Filed: 1979-08-22
Abstract: Round logs, planks or other pieces of wood, successively conveyed to a sawing machine, are automatically aligned in relation to a reference line. One pair of aligning elements has a setting member with stops varying in position relative to its bearing surfaces. Each stop limits the track of the element concerned but so as to permit its free movement in the opposite direction. Elements in further pairs are so intercoupled and activated that the element on the stop side attains the limiting position when the pair is closed. This permits optimum exploitation of the timber body using fixed or only slightly laterally adjustable saws.

Title: Solid state answering circuit for telephone subscriber's appts. - has digital storage with input and output coders for short recorded announcement messages
Inventor: WEISE GUENTHER
IPC: H04M1/64
Filed: 1979-12-13
Abstract: Integrated circuit storage for short recorded announcement which can be incorporated in the subscriber's telephone apparatus. The storage is a read/write RAM unit with CODECs to interface with the analogue telephone circuitry. To record, an announcement is spoken into the telephone microphone (M), amplified (SV), fed through a CODEC (NP) to convert it to PCM for storage in the RAM read/write store (RAM). Control circuitry (AS) and an LED or liquid crystal display (AK,BL,ZK) indicates the capacity and fill of the store. To read out, the announcement is initiated by an opto coupler (OK) circuit coupled to the telephone bell circuit across the telephone A and B wires. The opto coupler output starts the control circuit (AS) so that the RAM reads out into a CODEC (PN), through an amplifier (WV) and transformer (U) to a line dependent upon relay closures (H,W).

Title: Addn. of surface-active solids to hydrocarbon coking feeds - increases yield and reduces fissuring tendency of coke
Inventor: LASK GERT-WILHELM DIPL CHEM DR
IPC: C10B55/02
Filed: 1980-03-14
Abstract: In the coking of hydrocarbons which also yield tars and gases, finely-divided mineral materials are intimately mixed with the feedstock before bringing to coking temp. in a coke oven. The minerals are surface active, e.g. dried gels, clays, dried red mud, kieselguhr, active carbon, expanded perlite or expanded vermiculite. Their internal surface is pref. greater than 100 sq.m/ g., 90% of the particles are pref. less than 0.1 mm in size, and they are pref. added as 0.1-10 wt.% of the mixt., the amt. depending on their internal surface area. The yield is increased and the fissuring tendency is reduced. The additive adsorbs the volatile hydrocarbons before they can escape and assists their cracking, to yield coke. The particles of additive and coke make the whole mixt. lean and thereby reduce the fissuring tendency of the total coke prod. By using small particles, the importance of premature blocking of pores is reduced.

Title: Multicolour random patterning of moving fabric - by application of thin film of two or more unmixed dyestuffs
IPC: D06B11/00
Filed: 1980-04-05
Abstract: In a patterning process for producing a random pattern of at least two colours on a continuous sheet of fabric, etc., a uniformly-thin film of dyestuff equal in width to the fabric width flowing onto the moving fabric is modified by the addition of irregular patches of at least one different liq. immediately before the application to the fabric. The second liq. may consist of a dyeing assistant, a thickener, or a thicker or thinner dyestuff. The first liq. flows onto the fabric down an inclined plate, above which is situated a distributor for the second liq., which drops the second liq. into the moving film just before it meets the fabric. This procedure gives a novel colouring effect intermediate between dyeing and printing, having large-scale non-repeating patterns in two or more colours which blend gradually together at boundaries.

Patent DE-3018167-A1 (DE)
Title: Telephone number card index attached to set - with friction brackets and hinges for adjustment of viewing angle
Inventor: BREU KARL-JAN
IPC: H04M1/21
Filed: 1980-05-12
Abstract: To enable a subscriber to have frequently used telephone numbers conveniently within reach at all times a card holder (2) contains several cards (13) with register lips (33) which cards are held in position by virtue of pressure pads (30) exerting a lateral card pressure. If a card has to be lifted out for readout, the remaining cards do not follow because they are retained by friction. Similarly, the selected card does not drop back. The card holder (2) is hinged on axle studs (19) which engage in holes (20) of a prolonged side portion (24) of the card holder frame (2). The side portion (24) is elastically movable by a slight outwards pressure because it is partly separated from the card frame by slots (25). The outward pressure is produced when the unit is inserted downwardly. The user may swing the card frame backwards to adjust the viewing angle. This movement is limited by a pin (26) integral with a side-bracket (23) of the axle stud support bracket (18) because of a recessed stopping portion (27) moulded into the extended frame body. The cards are made slightly wider at the bottom to prevent them from being drawn out completely against the pressure pads (30).
