Title: Plastics blow-moulding machine has cyclical drive - from cam driven by exactly timed drive shaft to minimise inertia forces
Inventor: FROHN WALTER DR ING
IPC: B29C49/32
Filed: 1980-01-22
Abstract: A machine for the prodn. of plastics blowmouldings, e.g. bottles, comprises a blow mould closure unit which receives a parison esp. from an extruder head at an upper transfer position and travels down with the parison to a lower blow moulding position. The up-and-down drive for the blow mould closure unit is provided as follows: a main drive shaft is intermittently driven during separate drive periods each comprising exactly equal angles of rotation, the stop periods between these drive periods being controlled by an adjustable timing element, the up-and-down drive is constructed as a closed cam directly driven by this main drive shaft and completing one complete cycle of the up-and-down drive during one drive period. The cam possesses portions of zero slope between those portions which define the raising and lowering movements. Preferably, the main drive shaft also drives cam discs for controlling subsidiary movements or initiating switching operations. Simplified construction of the drive and control system, reduced mass forces and reduced accelerations, and reduced energy consumption. These result also in reduction of wear on the components.

Title: Rotor for large hydroelectric machine - has non-circular rim for compensating deformation at high speed by evolving circular shape
Inventor: ANNEN HEINZ
IPC: F03B3/12
Filed: 1980-03-04
Abstract: The rotor (1) has a control hub (2) and radial rotor blades (3), with a rim (4) joining their outer ends. The rim (4) has a non-circular configuration when the rotor is at rest, to allow for the deformation caused during high speed rotation, such that it exhibits a circular configuration at the required rotation rate with a given rotor temp. distribution. Pref. the rotor blades are integral with the rim and the hub and are prestressed in the radial direction when the rotor is at rest. The deviation of the rim from a circular configuration may be obtained by forcing the rotor blades between the hub and a slightly undersized circular rim, or it may be formed initially in the required shape.

Title: Electronic alarm clock for blind person - includes speech generator with memory and comparator, protected against faulty operation or cancellation
Inventor: LIMMER LOTHAR
IPC: G04G13/00
Filed: 1980-09-19
Abstract: The electronically controlled alarm clock, with a digital display, also has a speech generator for operation by blind or poor sighted people. The alarm is acoustically controlled, and the memory and counting system is protected against a faulty input and against inadvertent cancellation of the contents. This system uses a time counting device and a walking time memory with a comparator. This initiates the entry of the acoustic signals from the speech generator when the two sets of data signals are equalised. The speech generator operates to give the actual time by means of a delay circuit when a button is pressed. The walking time is controlled by a set of push-buttons forming a binary coded decimal assembly. Alternatively, an alpha numerical button system can be used.

Filed: 1980-09-19
Abstract: A separation slide meter has a measurement chamber contg. a rotating piston (3,4) and a separation slider (12) with its free end (13) in contact with the piston so as to form a seal between the chamber inlet and outlet. It ensures a uniformly good seal between slider and piston and enables a high degree of measuremement accuracy to be achieved. The free end (13) of the slider (12) contains a magnetic element (14). The piston exerts a magnetic force on the element so as to pull the slider towards it, thus forming the seal. The piston consists of magnetically conducting material at least in a region which lies at an equal distance from the piston external surface (7) during rotation. The slider can move in a housing aperture without expensive mechanical ancillaries.
Patent DE-3035871-A1 (DE)
Title: Profile measurement using contactless sensor - having lower scanning speed for critical profile regions and designed esp. for tight curves
Inventor: KLEMENT EKKEHARD DR
IPC: G01B11/24
Filed: 1980-09-23
Abstract: A method of measuring a measurement object profile involves moving the object w.r.t. a contactless sensor. The measurement arrangement produces measurement values from each sensor value within a defined time. The method provides reliable elimination of unacceptably large measurement errors, esp. with profiles contg. tight curves. This is achieved by adjusting the continuous relative speed between the measurement object (1) and the sensor (2) according to the profile so that the incremental distances (AX) covered in the measurement periods are sufficiently under at critical points on the profile. The speed is reduced for critical profile points and raised to a permitted higher value for non-critical regions of the profile. The profile is monitored for critical regions by evaluating curvature from the last three measurement points.

Title: Safety shut-off device for domestic gas connections
Inventor: GERSTNER HANS-JOACHIM
IPC: F16K17/36
Filed: 1981-01-29
Abstract: The invention relates to a safety shut-off device for domestic gas connections, i.e. for the connection pipes by means of which each individual house is connected to the gas main, which generally runs underneath the road. The invention can also be used in a similar manner for feed lines for other media in gas, vapour or liquid form. In the case of domestic connection pipes, there is the risk that they and/or the onward-leading gas pipes within the building will be deformed and thereby damaged and become leaky, due to the settling of the soil, the settling of the foundations, by unintentionally being caught and pulled up by excavators and other construction apparatus. In the case of gas, this can give rise to the risk of explosions. The object of eliminating this source of danger is achieved according to the invention by providing in the house connection pipe leading from the gas main into the house or in the gas pipe within the house leading to the gas meter installed in the house a safety shut-off element which is loaded in the closing direction by spring force or a weight, can be moved into the open position by an operating element and is held in this open position by a release device which, reacting to the spacing between a point on the gas feed line and the nearest wall of the building and/or to the angular position of this gas line relative to the wall of the building, releases the holding device when a predetermined adjustable spacing and/or a predetermined change in the said angular position is exceeded and thereby brings about the immediate closure of the shut-off element. Fig. 1 shows the installation of a device according to the invention in the vertical gas pipe leading to the gas meter. <IMAGE>

Title: Device for conveying rigid, flat printing products
Inventor: KRAFT WOLFGANG
IPC: B41F21/00
Filed: 1981-02-14
Abstract: In a device for conveying rigid, flat printing products from an automatic screen printing plant for producing hybrid circuit boards by the thick-film technique, a positioning device is provided which guarantees a high degree of register accuracy. The positioning device comprises a front stop and two side stops for the printing product. The front stop is designed as a stop body which is arranged at the end of a ram which is displaceable back and forth in a vertical sliding guide, can be raised with the aid of the ram via a sliding track plane into a stop position and can be lowered into or below said position into a further conveying position. In the raised stop position, the ram is pressed against the sliding guide surface with a force directed counter to the direction of displacement at the time when the printing product strikes against the stop so that it is impossible for the stop body to yield within the bearing tolerances, and a precise stop position is thus defined. As soon as suction air is switched on below the printing product, the effect of force on the ram can be lifted and the front stop body can be lowered virtually without friction into or below the sliding track plane. As a result, wear of the front stop is reduced to a minimum. This also applies correspondingly for the side stops which are designed as rollers which can rotate about vertical axles. <IMAGE>

Title: Clutch device
Inventor: NAUMANN HERBERT KARL
IPC: F16D23/12
Filed: 1981-02-20
Abstract: The invention relates to clutch devices for motor vehicles with a mechanical and hydraulic operating device for the clutch. According to the invention the clutch devices in the case of mechanical operation of the clutch are arranged between clutch fork and engine housing or transmission housing and in the case of hydraulic operation of the clutch are designed as master or slave cylinders. The object of the clutch devices is to prevent jerky engagement caused by operating error. The clutch devices, by virtue of their internal arrangements, control the speed of the engagement process, it being possible to adjust this speed by manual or automatic control. In addition, the clutch devices can be combined with a lifting and retaining device with, for example, electrical operation, it being possible to control the lifting and retaining device by detecting the torque of the drive shaft by means of strain gauges fitted on the drive shaft. This makes automatic disengagement possible before a vehicle goes into overrun conditions, and engagement occurs smoothly when the accelerator pedal is operated. In addition the subject of the invention permits automatic control of a manual shift transmission.
