Patent DE-3212647-A1 (DE)
Title: Bed having a bed frame with a two-part mattress body
Inventor: KAISER KARL
IPC: A47C31/12
Filed: 1982-04-05
Abstract: The invention relates to a bed or the like with a variable support firmness, the mattress of which is formed by two foam pieces of different length lying one above the other, the underside of the upper and longer mattress body and the upper side of the lower, shorter mattress body which can be displaced on a support having essentially mutually corresponding profiles, for example of sawtooth-type construction, which can be engaged completely or partially depending on the preset position of the two pieces relative to each other. The lower part of the mattress is in two parts and is arranged on a flat carrier of corresponding two-part construction so as to be displaceable on the support frame. Provided on the support frame between the two lower parts of the mattress and at their lateral borders are padded longitudinal supports which each have a foam strip and which correspond in their height, when the mattress is not loaded, to the height of the lower part of the mattress or exceed the latter by a small amount. The purpose of this foam strip is to lift the upper part of the mattress out of the lower part of the mattress when the mattress is not loaded so that the lower part of the mattress can be displaced relative to the upper part of the mattress without substantial friction. A reinforcement of the central support region and the lateral border of the mattress is likewise provided by these strips. <IMAGE>

Patent DE-3225656-A1 (DE)
Title: Device and method for producing a mechanical, permanent spliced joint between two optical waveguides (LWL) made from transparent quartz
Inventor: LE-HIEP TUYEN
IPC: G02B6/38
Filed: 1982-07-09
Abstract: The subject matter of the invention is a device (1) which consists of a transparent rod (2) and consists of two LWL receptor parts (2a, 2b) due to a plane division in the middle. The transparent rod has a continuous capillary in the centre for receiving the LWLs. In order to produce a spliced joint between two LWL (6a, 6b) made from transparent quartz in conjunction with a slight attenuation of the conducted light power, the two receptor parts (2a, 2b) are introduced in each case at the end face into a tube (4). <IMAGE>
Patent DE-3230081-A1 (DE)
Title: Transvenous, implantable pacemaker electrode
Inventor: SAUBERT HANS
IPC: A61N1/05
Filed: 1982-08-13
Abstract: In order to avoid dislocation, of pacemaker electrodes transvenously introduced into the heart, said electrodes are frequently provided with a corkscrew tip to be screwed into the wall of the heart. The screwing-in process is effected for example, by turning a mandrin. If this mandrin is already appropriately bent during insertion for the purpose of achieving arches, turning it results in a lateral shearing force on the head. In order to counter this undesirable effect the invention provides an electrode and the screwing-in process thus takes place by turning the electrode itself about a preferably bent mandrin, so that the mandrin determining the site of placement does not have to be moved during the screwing-in process.

Title: Paper-intake device for folding machines
Inventor: WOESSNER FRITZ
IPC: B65H5/06
Filed: 1982-09-15
Abstract: The invention relates to a paper-intake device for paper-converting or paper-processing machines. The paper, which is frequently supplied in corrugated form, is pressed down and smoothed by a special roller arrangement in the intake region. The roller arrangement consists of a number of narrow rollers which are arranged on a driving axle and whose peripheral surfaces are provided with integrally attached ridges. These rotating rollers press the pushed-in paper down by their ridges and cause it to vibrate, which favours paper intake by the following intake rollers. <IMAGE>

The compression spring (14) is arranged in such a way as to afford a good grip. Special fittings (17) are provided on the frame (15) for the guidance of the seat part (24) during its longitudinal displacement. For this purpose, the fittings (17) are provided with an elongated hole which is not visible from outside. In addition, a locking device is provided so that the seat part can be locked in various positions. <IMAGE>

Title: Voltage on-off controller
Inventor: MAHECHA-ORDONEZ HECTOR DIPL IN
IPC: H02M3/155
Filed: 1983-11-18
Abstract: In a voltage on-off controller (SSR), an input DC voltage (UE) is switched as a function of clock signals from a controller (R). In this case, the potential at the output of the switch (S1) alternates between the positive potential of the input DC voltage (UE) and a potential which is slightly negative with respect to a reference potential. The alternating potentials are converted by a voltage invertor (SI) into an output DC voltage (UA2), which is inverse with respect to the input DC voltage (UE). There is no need for a separate clock stage for the voltage invertor (SI) in this circuit. <IMAGE>

Title: A device which can be connected to a telephone set for separate recording of the time spent by different users operating the device
Inventor: BEHR KARL-GUENTHER DIPL ING
IPC: G07F7/00
Filed: 1983-11-19
Abstract: A device is described which can preferably be connected to a telephone set and which allows the telephone device to be used only by means of a data medium, a magnetic card or the like, which is issued to a group of authorised users and which also contains user identification data. The data medium serves to record the time spent by an individual user operating the device. Two solutions are proposed for this purpose. According to one solution, the device contains counting, summing and marking units, by means of which the elapsed operating time is recorded and marked on the user-specific data medium, if necessary as a complement or addition to times already marked on the data medium which are initially read into the device via a similarly provided read unit at the start of operation. According to the other solution, the data medium itself is designed at least partially as a chip with enough storage locations to allow the summation of the operating units to be carried out directly on the data medium, and to remove the need for special counting and summing units in the device.
