Patent DE-3120935-A1 (DE)
Title: Control device for a pump with adjustable delivery
Inventor: KIRKHAM STEVEN C
IPC: F16H61/433
Filed: 1981-05-26
Abstract: A control device for a pump (12) with delivery adjustable for a given pump speed of rotation and driven by a drive motor (10), the adjustable pump (12) having a servo cylinder (78) for regulating the stroke or other adjustment of the delivery. A charging pump (14) is also driven by the drive motor (10) and delivers charging pressure to the adjustable pump (12) via a throttle (40). On either side of the throttle (40), control lines (42, 44) are connected by means of which the pressure drop at the throttle (40) can be detected and relayed to a control element (52) of a regulating valve (46), which controls the pressure in the servo cylinder (78). On the lower pressure side the control element (52) of the regulating valve (46) is also loaded by a compression spring (72) so that in the case of a pressure drop over the throttle (40) and hence a decreasing speed of the drive motor (10) the control element (52) of the regulating valve (46) is gradually shifted towards the side of the higher but more sharply declining pressure on the inflow side of the throttle (40). The servo cylinder (78) is spring loaded towards adjustment of the adjustable pump (12) to maximum delivery and due to the gradually increasing pressure metered by the control element (52) of the regulating valve (46) is shifted towards a zero delivery setting, resulting in a gentle transition of the adjustable pump (12) between maximum and minimum delivery. <IMAGE>

Title: Safety device for projectile fuzes
Inventor: WEIDNER PETER ING GRAD
IPC: F42C15/295
Filed: 1981-07-03
Abstract: A safety device (15) for projectile fuzes (3) having a wind-driven impeller (35) for evaluating the air flow which surrounds a relatively slowly flying projectile (1), for obtaining an environmental unlocking criterion which acts after firing, is intended to be constructed in such a manner that functionally reliable and unambiguous unlocking of the final safety element (46) is ensured, for arming the fuze (3), at a low design cost. For this purpose, a brake lining (42), which is connected in a rotationally rigid manner to the wind-driven impeller (35), is supported against a fixed-position heat conductor (43) in order to obtain friction heat for heating an unlocking design element consisting of material with a so-called shape memory capability ("memory" metal), whose defined shape change (which occurs with a considerable amount of force being developed virtually instantaneously when a crystal-network conversion temperature is exceeded) is used to unlock the safety element (46) and possibly, furthermore, for arming the fuze (3) and/or, after a further heating time interval, for initiating self-destruction. A preferred application for such a safety device (15) is in the fuze (3) of a mortar or grenade-launcher munition, in the case of which, for ballistic reasons, the detection of a second environmental criterion (which does not occur until after it has been fired from the barrel) for the final arming of the fuze (3) is problematic and has not yet been implemented in practice. <IMAGE>
Patent DE-3139399-A1 (DE)
Title: Drive for a system which is capable of oscillation
Inventor: STEIGER ANTON
IPC: F01L9/10
Filed: 1981-10-03
Abstract: The known principle that a resiliently suspended mass (M) moves from one stable limit position into the other on the basis of half an intrinsic oscillation and is locked at the points of the reversal of movement is to be applied in systems with relatively large oscillating masses; therefore, the blocking device for the reversal of movement consists of dead-centre points of the oscillation made up of passive locking elements (21, 22); "passive" locking elements are to be understood as being blocking devices in which no accelerating force effect is exerted when the mass (M) oscillates into the limit position. <IMAGE>

Title: Labelling machine for bottles or the like
IPC: B65C3/22
Filed: 1981-10-12
Abstract: The invention relates to a labelling machine for bottles or the like, comprising a turntable which feeds the bottles received by an inlet starwheel past at least one labelling station for foil blanks and/or labels to an outlet starwheel. On the transport path of the bottles between the inlet and the outlet starwheel, there is a driven brush roller as the folding tool for the foil blank. Also provided in the region of the inlet starwheel or a preceding starwheel is a foiling station for a head foil blank. The brush roller can be displaced from a working position on the outlet starwheel into a working position on the inlet starwheel and can be changed over from right-hand to left-hand running. This labelling machine can thus be changed over to different foiling operations without a large outlay on apparatus, it being possible for one and the same brush roller to be used both for the tip foiling and for the simpler foiling with strip foil. For both foiling operations, the same brush roller is used during the final brushing-on of the foil.

Title: Self-propelled agricultural machine, especially for soil-working
Inventor: BAUR HELMUT DIPL ING
IPC: A01B3/50
Filed: 1982-06-08
Abstract: The invention relates to an agricultural machine, if appropriate for soil-working. The machine consists of a two-part machine body which is carried by vertically adjustable steerable driving wheels and, via an implement carrier, by an especially vertically adjustable supporting wheel. The driving wheels and the implement carrier are mounted pivotably on the top part of the two-part machine body which is rotatable about a vertical axis in relation to the lower part serving as a base. Such a machine can easily be manoeuvred because it can be rotated on the spot. It is therefore suitable for automatic operation. At the same time, energy necessary for driving the machine can be provided by solar cells. In view of the possibility that the machine can be operated as an automatic plough, there is no need for an attendant to look after the machine constantly, and therefore the machine can work in dependence on the available energy.

Patent DE-3329216-A1 (DE)
Title: Device for remote adjustment of the welding current in a D.C. welding current source
Inventor: WALTHER HELGE
IPC: B23K9/10
Filed: 1983-08-12
Abstract: It is customary when the welding place is remote from the welding apparatus to adjust the welding current via a remote adjuster connected via a cable to the welding apparatus. The disadvantage of this arrangement is that in rough construction site operation the danger of a cable fracture or cable breakage is very large, which can lead to defective weld seams. The object of the present invention is to provide a cable-less remote adjuster. The essence of the invention is that a handy, cable-less remote adjuster always carried by the welder is provided with two conducting surfaces, on which is superimposed a corresponding frequency of the welding voltage by contact of the conducting surfaces of a workpiece and a welding electrode. An evaluating circuit is provided in the welding current source, which appropriately increases or decreases the frequency of the welding current.

Inventor: SCHWARZ SIEGFRIED
IPC: A23L17/00
Filed: 1984-03-08
Abstract: A process for the production of a sild appetiser from sprats flavoured with herbs. In the process the manual or mechanical filleting of the fresh sprats is carried out directly after catching. The fillets freed from all waste are frozen in moulding chambers to form a fillet block and stored in a deep freeze. The fillet blocks, to produce individual fillets prior to introduction into a curing vat, are thawed by a heat generator during transport to the curing vat. The defrosted and thawed sprat fillets are stored with addition of a curing bath liquid enriched with 3-9% salt for a biological/enzymatic curing. The curing of the sprat fillets, depending on quality, storage conditions and storage temperature, is carried out over a period of approximately 4-14 days. The sprat fillets are brought from the vats to preparation benches or to skinning machines and either skinned mechanically or manually. The sprat fillets are placed in containers with addition of seasoning infusions composed of water, sugar and aroma substances, salt, sorbitol, syrup, spices and sodium benzoate and are then automatically sequentially sealed and are fed via collecting sections to an automatic collective packager.
