Patent DE-3205450-A1 (DE)
Title: Automatic positively controlled yarn-feed device for use in a knitting machine
Inventor: SAWAZAKI MASATOSHI
IPC: D04B15/48
Filed: 1982-02-16
Abstract: In a yarn-feed device of a knitting machine, the yarn (38 and 38A) fed into the machine is guided respectively round rotating wheels (15 and 16) which each have a circumference divided into two vertically separated regions (18 and 19), each containing a surface of relatively low friction and a surface of relatively high friction. When no yarn is needed, fixed eyes (21 and 22) and moveable eyes (30 and 31) guide the yarn round the region (18) of low friction, so that no feed takes place; when there is a need for yarn, the tensile stress of the yarn ensures that the eyes (30 and 31) lift the yarn into contact with the region (19) of high friction, so that the yarn is fed as a result of the rotation of the wheels (15 and 18). <IMAGE>
Patent DE-3207689-A1 (DE)
Title: Moving staircase (escalator)
Inventor: WAGON HORST PROF DR ING
IPC: B66B23/02
Filed: 1982-03-01
Abstract: Compared with the frequent stoppage of the moving staircases of the previous type, the moving staircases according to the proposed principle are to bring an improvement. This consists essentially in the fact that the step formation is obtained merely by retention as a result of different revolving speeds inside an endless, hinge-like slat conveyor. Fig. 1 shows an escalator which only works in the ascending direction. The step formation by retention is initiated via a driver chain (Fig. 4), and in fact in such a way that at most an angle can occur between two adjacent slats. Every second slat is equipped with two rubber-tyred rollers (Fig. 6) which are supported on tracks (Fig. 7) to the left and right of the actual stair. In the slow-speed, step-forming section, the movement of the escalator is effected via chain-drawn driver carriages (Fig. 10), while in the faster section the slats are driven via driver discs (Fig. 2). The foot drive can either be designed in such a way that the moving staircase conveys only in the ascending direction (Fig. 1) or in such a way that ascending as well as descending conveying is also possible. <IMAGE>

Title: Mini skittle alley
Inventor: GERENT WALTER
IPC: A63D3/00
Filed: 1982-06-23
Abstract: The invention relates to a table-top mini skittle alley which can be erected in enclosed premises. Embodiments known hitherto are too inconvenient to handle and fail to meet the high standards required of a modern game. Mini skittle alleys of automatic design are thus not to be found. The invention has provided an automatic and robust game, in the manner of a coin-operated machine, which also meets the requirements of reliability and availability. As a result of a special design of individual structural elements, shown in Fig. 4, a combination of features of shooting and skittles is provided. The device is an indoor game which is also suitable for use in licensed premises or in arcades. Because of the largely mechanical design, it can also be set up in the open air. <IMAGE>
Patent DE-3226750-A1 (DE)
Title: Conical piston operating in a cylinder having the shape of a hollow cone
Inventor: BENDT EWALD
IPC: F02F3/00
Filed: 1982-07-15
Abstract: Piston and cylinders with horizontal tops are known for internal combustion engines. Deviations from this horizontal configuration of the tops are used to improve combustion and scavenging in the cylinders. If the piston top is designed as a cone, the pressure in the cylinder acts on the chords of the cone. A higher force is achieved than with a horizontal piston top of the same diameter. In order to maintain the volume, it is necessary to give the cylinder the same shape as the piston. The sliding surfaces remain cylindrical as before. Tests have shown that the conical piston is superior to the horizontal piston by about 48 %. The gain in force can be demonstrated on a balance and using the parallelogram of forces. In internal combustion engines, the gain in force has a favourable effect since the volume of the cylinder can be reduced by the gain in force and pollution of the air is lower.

Patent DE-3242919-A1 (DE)
Title: Image output system
Inventor: MANIWA YOSHIO
IPC: G06F17/21
Filed: 1982-11-20
Abstract: An image output system with raster scanning for outputting an image in the form of a dot pattern corresponding to a character code and an output control code is created which are transmitted from a computer or a similar main device. The character code from the main device is stored in a common page memory both in longitudinal and in transverse printing mode but in different orders with respect to the addresses. The width of a character is represented by an integral of a predetermined basic unit so that the unit can be adapted to various character widths. The position on a sheet on which a character is to be output is represented by a predetermined note and is stored in the page memory together with a corresponding character code. The character code read out of the page memory is transformed into a dot matrix pattern by means of the basic unit by the character pattern memory. It is not necessary to change the type of data reading either with longitudinal or transverse printing since the output positions, sizes and other factors are taken into consideration as long as character codes are entered into the page memory.
