Patent DE-2420307-A1 (DE)
Title: Non-jam roller guide for furniture drawers - has peripheral strip on cupboard rail engaging without lateral play over roller on drawer
Inventor: GRIGO HORST
IPC: A47B88/14
Filed: 1974-04-26
Abstract: The cupboard rail (4) is screwed onto the inside wall (2) of the cupboard and a drawer rail (6) is fastened to the drawer (1) and adapted to rest on the cupboard rail (4), both rails being provided at one end with rollers (5, 7). A peripheral strip (4''') is mounted at the upper horizontal guide arm (4"') of the cupboard rail (4) to engage over and round the roller (7) provided at the rear end of the drawer rail (6). The drawer roller (7) which when the drawer is extended rests against the underneath of the upper horizontal guide arm of the cupboard rail (4) thereby remains tightly enclosed on the sides by the peripheral strip which restricts the lateral play and thus increases the lateral stability. The roller (5) on the front end of the cupboard rail (4) preferably projects beyond the upper horizontal guide arm.

Title: Foamed plastic articles with compact skin - obtd. by accurately controlling temp. of foamable mixture during injection-expansion
Inventor: JOHANNABER FRIEDRICH DR ING
IPC: B29C44/04
Filed: 1974-04-30
Abstract: Structured, foamed plastic articles with a smooth, compact outer skin and foamed core are obtd. by closely controlling the temp. of the molten plastic matl. that contains a blowing agent, and enters the nould cavity, this temp. being initially low, then raised to at least the expansion temp. of the mixt., and finally lowered. Temp control is effected by either (a) controlling the mass temp. in the melt collection space of the plasticising cylinder, or (b)by changing the shear deformation of the melt during injection. Excellent control over the temp. of the mass during injection and expansion, ensures prodn. of high quality articles in a simple economical manner.

Title: Particle suspension analyser with capillary suspension feed - has variable suspension feed rate from capillary
Inventor: KACHEL VOLKER DR ING
IPC: G01N15/12
Filed: 1974-05-08
Abstract: The analyser has a compartment containing a first electrode and particle-free electrolyte which flows through a measuring orifice into a second electrode compartment at a lower pressure than the first, whilst the particle suspension enters the electrolyte from a capillary tube at a point before the orifice. The first compartment is sealed off from atmospheric pressure and the electrolyte enters this compartment through an inlet via a pipe from a variable-height pilot container. The electrolyte level in this container is controlled independently of the container height in such a way that the container height determines the pressure in the first compartment.

Title: Overheating protection arrangement for cine projector - has fast-ating relay in current circuit of cooling motor
IPC: G03B21/16
Filed: 1975-03-07
Abstract: The cine projector is fitted with an electrically driven blower, with the blower motor (2) is connected in parallel with a relay (1).

Title: Fault monitoring unit - for use with a large number of working positions on one or more textile machines
Inventor: GUSE ROLF DR ING
IPC: D01H13/32
Filed: 1975-06-26
Abstract: In the common continuous monitoring of the working positions of a number of textile machines, each working position is associated with >=1 measuring position, which delivers >=1 yes/no information concerning the operationally relative processes or conditions. The measuring positions of a group of working positions are incorporated as members of a digital circuit and are connected to a data circuit. The beginning and end of each data circuit are connected to a special central measuring value collecting unit, in which all the steps required for the storage, addressing and recall of the measuring values are carried out. The central measuring value collecting units of several groups are connected by conductors to a central computer in which the data transmitted from the central measured value collecting units are processed. The optimum prodn. speed of a given textile machine e.g. a ring spinning machine can be determined relative to the costs of production stoppages due e.g. to the number of defects such as yarn breaks. In general, such faults are detected at much reduced intervals so that a larger number, caused e.g. by higher spinning speeds, can be economically tolerated.

Title: Diversity aerial system for radio receivers - automatically scans and registers each signal level and switches appropriate antenna
Inventor: BERGANDER ARMIN DIPL ING
IPC: H04B7/08
Filed: 1975-08-05
Abstract: The diversity reception system can be used with aerials having widely different gains. Each aerial is terminated in a selector unit (7) by which the chosen antenna can be connected to a single receiver (8). The signal level from each receiver is taken from the intermediate-frequency stages of the receiver and both the average level (12) and actual value are passed to a comparator (14). The average level for each aerial is stored in a register (13). The comparator output which is related to a desired signal level consistent with a good signal/noise ratio, is connected to a control unit (10) which operates the antenna switching device. Each aerial has a signal level detector (4, 5, 6) and the automatic selector connects the most suitable aerial output to the receiver.

Title: Friction transmission for pneumatic tyred wheel - with pivotted friction roller linked to engine by reduction gearing
Inventor: SCHMITT KARL DIPL ING
IPC: B62M13/02
Filed: 1975-10-17
Abstract: The drive motor (3) is mounted on an arm (4) hinged on the support forks (1) of the driven wheel (2) and is linked to the friction drive roller (7) on top of the pneumatic tyre, by a reduction gearing. The friction roller is also mounted on the swing arm, and is pressed against the wheel by a spring (8). The reduction gearing can be altered, using a simple hub gearing (6) which is light and compact. This allows the transmission to negotiate steep hills. The point of contact between the friction roller and the tyre is in front of the line joining the pivot point (5) of the swing arm and the hub of the wheel. This provides increased roller pressure during braking and during increased torque.

Title: Mobile radio telephone communications system - selects fixed transceivers according to best reception between mobile station and central
Inventor: NEDTWIG JOACHIM DIPL ING
IPC: H04B7/022
Filed: 1975-11-29
Abstract: The radio voice communications system selects the fixed transceiver with the best signal level for making a radio link between a mobile transceiver and the fixed central station. This fixed transceiver is selected by using signal level detectors in each fixed transceiver to measure the S/N ratio or field strength of signals received from the mobile transceiver. Those signals with the lower field strength are delayed longer than stronger signals. The central station receive only the first signal to arrive, i.e. that having the highest level. The central station communicates with the mobile via the already-selected fixed transceiver.
