Patent DE-2608735-A1 (DE)
Title: Model electric locomotive with light carrier rods - have ends which are forked with one red end and one clear to provide interchangeable light colours on train ends
Inventor: BRATOVZ MATJAZ
IPC: A63H19/20
Filed: 1976-03-03
Abstract: This model electric locomotive has three lights at each end. The front lights in the travel direction of the locomotive are white while the rear lights are red. This is achieved by connecting the lights at each end to forked light carrier rods (3, 4). The end of one fork (6, 7) is coloured red while the other (5, 8) is colourless. In the gap between the rod end of one fork (3, 4) and white end of the other is light bulbs (11, 12). These bulbs are connected so that only one light is lit at a time, this being dependent on the direction of the current passing through the locomotive to determine its direction of travel. Consequently the lights change colour at each end, when the locomotive changes its direction.

Title: Sand entry prevention insert for borehole well - deflects sand flow and lowers water column when pump starts
Inventor: FINK LEONHARD
IPC: E03B3/15
Filed: 1976-07-14
Abstract: The well bore hole has inserted tube for preventing entry of sand with the water. This arrangement prevents entry of sand into water and rise of sand through the water pipe. The inserted tube separates the water entry and reduces the entraining force of the water. The water column within the well bore drops when the pump starts. The enclosed space between the well filter and outside wall of the inserted tube controls the movement of the water carrying sand without changing the flow rate until it reaches the well tube. The water entry from the well area is separated by the inserted tube from the dropping water column within the well when the pump is started.

Title: Separation of photographs in strip from printer - uses marks provided between frames which are stamped out in cutting leaving no mark on finished print
Inventor: BUEHLER RUDOLF
IPC: G03B27/52
Filed: 1976-09-08
Abstract: The device marks the positions at which strips of photographic copies are to be cut by the application of a reference mark during the photographic process. The object is to provide a simple marking and scanning system which neither leaves marks visible on the separate prints, nor involves the need to trim the edges to remove such marks. The marks are applied during the photographic process to the white frame between successive copies, or to the point of overlap of marginless prints which is illuminated by a stationary light source (5); the light source controls a stamping device rather than a knife which punches out a narrow strip of width corresponding to the thickness of the mark, so that the mark itself is removed in the process.
Patent DE-2640930-A1 (DE)
Inventor: SCHWARZ SIEGFRIED
IPC: F23N5/20
Filed: 1976-09-08
Abstract: The thermal relay for furnace systems has a bimetallic arrangement which is influenced by an electrical heating winding (5) and operates switching contacts. A control element (17) which is arranged in the circuit of the heating winding (5) is influenced by a control device (20), which is matched to the heat-loss characteristic of the bimetallic arrangement, in order to produce a shift which rises linearly per unit time. A switching contact, which is operated by the bimetallic arrangement and executes a switching command for the furnace system, at the same time bridges over a device (19) for changing the setting of a required-value transmitter (16) in a contact-free manner and without touching. Possible refinements: a temperature sensor (10) is thermally coupled to the heating winding (5). A first comparator (13) compares the measurements of two measurement stores (11 and 12) in synchronism with a clock transmitter (14). A second comparator (15) compares the output of the first comparator (13) with the required-value transmitter (16) and controls a thyristor (17). A line (18) is used for pulse feedback for self-testing. A monolithically integrated module, which contains two diodes as temperature sensors in a bridge circuit, is arranged on a heat conducting path of the bimetallic arrangement. <IMAGE>

Title: Coupled skis for learner skiers - has pivoted bar connecting pair of skis which prevents skis crossing over each other
Inventor: WIMMER SEPP
IPC: A63B69/18
Filed: 1976-11-26
Abstract: A pair of skis ar coupled together by a cross bar which is pivoted at each end to a vertical rod. The vertical rods are mounted in cylinders fixed to the skis at about 10 to 20 cm from the end. The rods are retained in the cylinders by cap nuts which allow the rods to rotate about their vertical axes. The coupled skis have thus a limited degree of movement relative to each other in the longitudinal and vertical directions and can also rotate to a limited degree relative to each other. But the skis are unable to cross over each other and so are very useful for people learning to ski and reduce the chance of accidents.

Title: Tachometer operating from standstill to high speeds - uses diodes and phase-locked loop controller and has pulse frequency increased in proportion to rotational speed
IPC: G01P3/486
Filed: 1977-03-17
Abstract: The tachometer is of a type that will operate from standstill to high speeds and consists of an optical pulse source made from two separate interrupt devices. Each device comprises a light source and photo diode together with a light barrier. The light barriers (4, 5) are mounted on the interrupt wheel (1) at 180 deg. angular (+-) 180 deg. signal phase apart. The separate output signals are combined to give a combined signal converted into frequency proportional to rotational speed. The ac portion of the current of the output signal is passed through a peak d.c. rectifier and this resulting figure is used to indicate movement or stillness of the wheel. The pulse frequency is increased using a phase-lock loop control and this decreases the measurement time.
