Title: Film magazine having film speed display
Inventor: NAKAYAMA YOSHIAKI
IPC: G03B7/24
Filed: 1981-12-18
Abstract: Electrically or optically detectable elements are provided as desired at predetermined first to fifth display positions on a photographic film magazine. The detectable elements provided in the first to fifth display positions represent multipliers of 2x, 4x, 16x, 2<1/3>x and 2<2/3>x. The speed of the film contained in the magazine is given by multiplying a predetermined standard speed value by the multiplier or multipliers which are represented by the elements present. If the speed of the film contained in the magazine is the same as the standard value, no detectable elements are provided at any of the positions. Speed sensing elements on a camera can either be capable of detecting the detectable elements at all first to fifth positions, or be capable of detecting the detectable elements only at the first to third position. In the latter case, the exposure is controlled on the basis of a speed one or two steps lower than the exact speed of the film contained in the magazine.

Title: Engine heater for water-cooled internal-combustion engines with pump-circulated cooling system
Inventor: MIENHARDT HEINZ
IPC: F02N19/10
Filed: 1982-04-01
Abstract: An embodiment of the abovementioned invention is shown in the drawing and is described with reference to this in the following abstract. The drawing shows: insulated tank, water pump electrically driven by the vehicle mains, time switch (adjustable electrical time-lag relay) with push-button operation and function pilot lamp, pressure valve with circulation bore, feed line from the engine, return line to the engine, non-return valve to the feed line, non-return valve to the return line, non-return valve to the connecting line, remote thermometer of the insulated tank. The operating principle of the invention shown lies in the fact that the quantity of cooling water in the insulated tank during operation is circulated  by way of the circulation bore of the pressure valve (4) and thereby gradually raised to operating temperature. The amount of heat which is thereby stored in the contents of the tank is available for the next starting for warming up the engine (approx 16 to 20 hours, depending on the type of insulation). By pressing the start button of the electrical timer switch (3) the circulating pump driven by the vehicle mains is put into operation until such time as the hot cooling water of the insulated tank has been replaced by the cold cooling water of the engine; a function display is provided by the pilot lamp at (3). The main purpose of the invention is thereby achieved: that is to preheat the engine without an external energy supply before the starter has been operated. <IMAGE>

Title: Display and evaluation device for measuring the track resistance in order to determine the permissible speed and widening of the gauge
Inventor: BINGMANN WALDEMAR DR ING DIPL
IPC: B61K9/08
Filed: 1982-10-06
Abstract: During measurement of the widening of the track using the track resistance measuring device, a gauge measuring rod which is moved by the pressure ram of the apparatus is used by said device to indicate directly on a diagram the speed which is still admissible in the event of excessive widening of the gauge. The diagram, covered by said rod, for the functions of gauge widening and speed which are decisive on a section of railway, is contained in a replaceable manner in a push-in frame attached to the instrument carrier and is subdivided by a load limit line into an admissible and inadmissible area. The push-in frame guides a moveable bolt which is moved by the pressure ram of the measuring device with the gauge measuring rod which indicates the widening of the gauge on the diagram. When the limit values are exceeded, the slow travelling speed which is still admissible with adequate reduction of the contact pressure is determined in optimised form by means of a beam line thread on the load limit line of the diagram.

Title: Glass feeder for molten glass for the production of hollow pressed glass
Inventor: BOETTGER DIETHER
IPC: C03B7/07
Filed: 1983-04-21
Abstract: The invention refers to a method and an apparatus for the production of hollow and/or pressed glass. The object of the invention is to propose a method and an apparatus by means of which the cooling of the glass can be carried out without temperature inhomogeneities. In accordance with the method of the invention, the molten glass is conducted from the glass furnace into a stirrer unit and led further into the glass feeder. The glass in this glass feeder is heated homogeneously by the passage of current. Furthermore, by means of purely thermal convection flow along the limiting walls, the desired removal of heat is imposed upon the glass. The corresponding apparatus is such that a glass feeder is provided between the stirrer unit and the glass outlet, the height of the glass feeder and thus the height of the column of glass being greater than its width.

Patent DE-3323281-A1 (DE)
Inventor: SCHMITT WALTER ING GRAD
IPC: G01B7/00
Filed: 1983-06-28
Abstract: A system for error monitoring in a photoelectric incremental length measuring device for the measurement of the relative position of two objects is described. The measuring device generates at least one measuring signal obtained during the scanning of a scale by means of a scanning unit. This signal is fed simultaneously to an evaluating unit and to an error monitoring unit. In the event of faulty signal parameters of the measuring signal, the error monitoring unit generates an error signal. The measuring signal is applied to an inverter and to a first AND gate. The output of the inverter is applied to a second AND gate. The two AND gates also receive the error signal as a second input. This error signal brings about an in-phase switching of the output signals of the two AND gates. The in-phase state of the signals generated by the AND gates is detected by a phase discriminator of an external evaluating unit, which generates an error signal on a respective line.
Patent DE-3330962-A1 (DE)
Title: Screw-limiting device
Inventor: BEYHL EBERHARD DIPL ING
IPC: B25B21/00
Filed: 1983-08-27
Abstract: The screw-limiting device is a screwdriving tool for electrical driving machines, in which the torque transmission between the machine spindle and the screwdriving insert is interrupted as soon as the screw head of the screw to be screwed in has reached a certain clamping length. There is a path-dependent torque uncoupling in which the maximum torque is available until uncoupling is effected. Constructionally, this is solved in that the coupling shaft as drive element is mounted in the coupling sleeve as output element and is either locked or unlocked by means of balls. A control sleeve with an annular groove ensures the appropriate position of the balls, performing this path-dependently. An adjusting and checking ring, which is screwed onto the control sleeve, serves for adjusting the travel with the various types of screw fastenings. <IMAGE>
