Patent DE-2448106-A1 (DE)
Title: Closure and carrier for bags, packages etc - uses elongated U-shaped insert around which fits carrying handle
Inventor: POPP EUGEN
IPC: B65D33/06
Filed: 1974-10-09
Abstract: In one design the insert is an elongated U-shape (3) with two prongs (3.1, 3.2) whose length corresponds to the width of the pouch or sack when it has its two seamed halves pressed flat together. The spacing between the two prongs corresponds to the thickness of the pouch material when the two border halves (2, 1, 2.2) are closed together. In order to facilitate introduction of the insert into the bag, one prong is longer than the other. The insert may be in the form of a wire with a round or oval cross-section or made from sheet metal with semi-circular sections.

Title: Data transmission system with frequency keying - is for binary signal bits and spacings represented by half-periods of two frequencies
Inventor: YOUNG ROBERT ERIC
IPC: H04L27/10
Filed: 1975-01-24
Abstract: The first frequency is a control or keying frequency, and the other is a different keying frequency. The transmitted signal is approx. a sinusoidal signal, whose phase is not interrupted during keying; bits and symbol spacings are fitted into the half period of the corresponding control or keying frequency, and the wave form slope at cross-points is constant. Means are provided for storage of the coded pulse wave and for its conversion into a waveform whose periods corespond to the bits and symbol spacings, so that they can be inserted into half-periods of the corresponding control frequencies; filters convert the produced and so adjusted waveform into a nearly sinusoidal wave.
Patent DE-2508550-A1 (DE)
Title: Data transmission system for vehicle control - modulates pulse length and delayed pulses give carrier wave at receiver
Inventor: GENDROT ANDRE JEAN-CLAUDE
IPC: H04B1/40
Filed: 1975-02-27
Abstract: At the transmitter is generated a recurrence frequency varying as a function of data to be transmitted with pulses whose duration is rotably less than their recurrence period. These pulses modulate a short range very high frequency carrier wave. The receiver demodulates the carrier wave received and restores the pulses, then generates from these pulses a signal modulated as a function of their recurrence frequency and representative of transmitted data. The receiver generates from each of the restored pulses, a similar but delayed pulse which modulates with the aid of the delayed pulse a new short range carrier wave for relaying the wave received, whilst inhibiting the reception at least during the duration of each delayed pulse.

Title: Air-filled spring suspension for mattress - has inlet and outlet valve for adjusting pressure and comfort of padding
Inventor: HERBST ALBERT
IPC: A47C27/14
Filed: 1975-04-15
Abstract: The air-filled spring suspension for mattresses and the like has a system of air cells (3) connected together directly or by air pipes (4) to form the air suspension core which is incorporated in e.g. a standard mattress (1) which is made from foam (2) or is filled with a comparatively soft filler material. These air cells can be filled with more or less air as required and the cavities are designed so that the air permeability of the mattress is not reduced at all or only by an insignificant amount. An air pressure gauge can be built in to allow the user to accurately determine the pressure which he finds most comfortable and which he can then set as and when required by means of the air inlet and outlet valve (5).
Patent DE-2517184-A1 (DE)
Title: Production method for integrated circuit - involves ion implantation mask which is produced on surface of substrate
Inventor: MAI CHAO CHEN
IPC: H01L21/8234
Filed: 1975-04-18
Abstract: The mask consists of an oxide layer with first zones permeable for ions of a certain energy, and with second zones impermeable for these ions. The first zones lie over transistor channels whose conduction relative to the substrate must be changed. The substrate with the mask is exposed to an ion source with the specified energy for a specified time in order to produce a specified change in the substrate in the channel area. A diffusion mask consisting of an SC layer and of an oxide layer (12) is formed. It defines sources and drains of FET's, while the SC layer forms edges of the channels. Ions are diffused through the mask, and sources, drains and the SC layers are connected into an integrated circuit.

Title: Controlled dyeing of stainless steel articles - by measurement of potential of test sample in the bath
Inventor: RUHSTORFER FRIEDRICH
IPC: C23C22/77
Filed: 1975-10-24
Abstract: Controlled dyeing of stainless steel articles by immersion in a hot bath until the potential between the surface of the steel and reference electrode reaches a value corresp. to the required shade, in which the potential is measured on a special control sample in the bath. The contro sample, of the same compsn. and surface condition as the stell articles, is pref. suspended with the reference electrode in an insulating tube, e.g. of glass, open at the bottom and immersed in the bath. The suspension of the articles is simplified, since electrical contact to each is unnecessary, and they can be supported by insulating materials e.g. plastics, glass or enamelled metal. Colour achieved on the whole batch is not affected by presence of a few articles with different compsn. or surface condition, or by poor contacts.

Title: Thermoplastics tubular film prodn. - with pre-expansion in die and internal air cooling before cooling mandrel
Inventor: SIMS JUN ROBERT J
IPC: B29C48/10
Filed: 1976-02-28
Abstract: Prodn. of tubular film involves extruding molten thermoplastics (I), cooling with a directional gas stream so that it (partly) sets and passing downwards over a cooling mandrel. (I) is pre-expanded in the die before extrusion and the press. inside the tube is kept constant at 0.254-2.54 cm water column. Cooling is carried out continuously with a high speed air stream (II), from a slit in the cooling mandrel, the slit being at an angle of 25-35 degrees to the horizontal, in an amt. of 2.83-7.08 Nm3/min. (II) cools the inside of the tube and provides an air cushion between this and the mandrel, preventing sticking. High quality film can be produced in relatively high amts. (ca 181 kg/h of 178 cm wide lay-flat tube). Higher rates of prodn. (227-245 kg/h) are possible with plastics which are difficult to process (e.g. polypropylene).
