Title: Toner applicator for photocopier - has agitated gravity feed hopper and sensor controlled release onto substrate
Inventor: STRAUCH PETER
IPC: G03F7/28
Filed: 1979-12-20
Abstract: The toner powder applicator for a photocopier has a sensor (2) on the endless band feed to determine the length and position of the charged image and to operate an agitated hopper feed (4) to drop toner over the charge image. The surplus toner is removed by two brush rollers (11,10) with excess powder collected by a suction duct. The remaining image is fixed and excess toner removed by further brushes (16) and extracts (15) before the copy is dropped into the out tray (19). The band is cleaned by another brush (14) and suction duct (15) before the next image is applied. The machine is enclosed and has no danger of spilling toner outside.

Title: Punch
Inventor: MUENKEL ERICH
IPC: B26F1/36
Filed: 1981-04-03
Abstract: The invention relates to the domain of office technology, in this case to small office devices in particular. The predominant, discontinuous single-piece method used for producing these devices (punches) is replaced by methods which are more economical when the devices are produced in large numbers. Extrusion moulding and injection moulding are included in these methods. In order to be able to use these technologies, the punch mechanism is designed in accordance with the loose roll principle and the punch is divided up into supporting and non-supporting parts. The latter are finish-mounted without reworking as semifinished products which are cut to length and/or as plastic preforms. The exploded drawing shows the basic structure of the punch. The compact, modern shape means that this punch can be used for a wide range of applications, in the office, as a second device at home, or as a promotional gift. <IMAGE>

Title: Measuring arrangement for measuring and displaying the pro rata quantity of heat dissipated by the heaters (radiators) in a prescribed number of flats of a block of flats
Inventor: HENNEBERGER HEINZ DIPL ING
IPC: G01K17/08
Filed: 1981-08-01
Abstract: A measuring arrangement for measuring and displaying the pro rata quantities of heat dissipated by the heaters in a prescribed number of flats of a building or a block of flats has for each of a prescribed number of heaters of a flat at least one heater temperature sensor in the form of at least one temperature-dependent resistor. All the temperature-dependent resistors in a respective flat are connected in series in order to form an output signal which is dependent on the heater temperatures. At least two measuring circuits having a series connection of the temperature-dependent resistors are provided for each flat. The measuring device has, in addition, switching means which respectively connect a constant-current source, serving to supply power, onto the respectively associated measuring circuits of a flat in a sequential fashion. These switching means are actuated by a central measuring and control device, with the aid of which in addition the share of the quantity of heat which is actually consumed in each flat is calculated and is digitally displayed on a downstream central display device for each individual flat and overall for the entire block of flats. For the purpose of obtaining the display signals, use is made of a microprocessor which also processes the reference signals of a reference circuit. <IMAGE>

Title: Lever piston engine
IPC: F01C9/00
Filed: 1981-09-24
Abstract: The invention relates to an internal combustion engine with lever pistons for the transmission of combustion pressure in the working chamber of the lever piston engine to the connecting rod to the crankshaft, especially for motor vehicles and/or sporting aircraft. In internal combustion engines of this type it is necessary to increase the economic efficiency. The object of the invention is to transmit the combustion pressure in the cylinder through the piston more efficiently to the connecting rod or crankshaft. According to the invention this object is achieved in that the lever piston engine is assembled from a lever piston, which has one or up to four piston sides (drawings fig. 1, 2, 3) with a piston axis from which the lever function of the lever piston is derived, the connecting rod, which transmits the work of the lever piston to the crankshaft, and the respective working chamber. <IMAGE>

Filed: 1981-10-01
Abstract: The invention relates to a drive for the work rolls of a vertical rolling stand, especially for billet rolling mills, which is provided with a vertical transmission comprising pinions, output shafts and universally jointed spindles. The object of the invention is to utilise the internal spaces of the pinions and universally jointed spindles by inserting the output shafts of the pinions of the vertical transmission for driving the vertical rolling stand in a way which makes it possible to perform the vertical adjustment of the work-roll casing (cassette) for the setting of the desired pass size of the work rolls for the purpose of pushing the work-roll casing out of the vertical work stand horizontally, and to achieve this with a minimum overall height and mass of the rolling stand. The invention consists in that the output shafts of the vertical transmission are mounted in axially displaceable fashion by their upper slotted ends in hollow spaces of the pinions, the spaces being slotted from below, and are mounted in axially displaceable fashion by the lower slotted ends in slotted openings in the upper sleeves of the universally jointed spindles.
