Title: Environmentally friendly vegetable-based EP cutting oil
Inventor: SCHWINDLING JOACHIM
IPC: C10M169/04
Filed: 1987-08-22
Abstract: Cutting oils, hitherto, are either mineral oil products and can contain toxic solvents and a high halogen level, or are not suitable for permanent use since the vegetable products are insufficiently modified or occasionally also have highly toxic contents. The disposal of such residues has hitherto caused considerable difficulties. The novel cutting oil is therefore intended to be equivalent in quality but to be nontoxic to humans and the environment and to be considerably easier to dispose of. A cutting oil which comprises vegetable oil, glycerol, P,S additives, fatty alcohol sulphonates, ascorbic acid, gallic acid and indigo is suitable for prolonged application in machine tools and can be completely removed from swarf and workpieces by means of aqueous soda solution. This cutting fluid is suitable for all applications in machine tools in which very high cutting pressures occur.

Title: Method for identifying the occurrence of the same subscriber device address for a subscriber device in a ring-shaped communications network
Inventor: RICCATO ALDO DR
IPC: H04M9/02
Filed: 1988-03-04
Abstract: With the aid of this method, it is possible to identify whether the addresses (a) allocated to the subscriber devices (TLN) occur once or more often in a ring-shaped network. For this purpose, each subscriber device (TLN) transmits self-addressed address test packet information (ati). If the respective subscriber device (TLN) receives the address test packet information (ati) in unmodified form, its address (a) occurs once. If the respective subscriber device (TLN) receives address test reply packet information (tai), its address (a) occurs at least twice. The subscriber device (TLN) with identical addresses (a) which is switched by the ring-shaped network essentially depends on the ring activation duration. This presupposes that, in each subscriber device (TLN), self-addressed packet information can be received, evaluated and subsequently removed from the ring-shaped network. <IMAGE>
Patent DE-3809043-A1 (DE)
Title: Control device for electrical wheelchairs or the like
Inventor: WEEGE ROLF-D DR
IPC: G05G9/047
Filed: 1988-03-18
Abstract: The invention relates to a control device for electrical wheelchairs or the like, having a control lever to be actuated by hand, which is mounted by means of a universal joint so as to be pivotable in any desired direction and is sealed with respect to one housing part at a distance from the universal joint via sealing means. The sealing means have a sealing part which is connected to the housing part in a sealing manner and in which there is an opening through which the control lever extends in a freely movable manner. The sealing part has an outer surface shaped like a spherical cap whose centre lies at the point of rotation of the universal joint. On the control lever there is a cap connected to this in a sealing manner, which overlaps the spherical cap-shaped outer surface of the sealing part. The sealing means are thus rugged and virtually secure against mechanical and chemical damage, for example from hand-sweat. The cap can overlap the spherical cap-shaped outer surface with a small play, so that the actuation and reset forces of the control lever are uninfluenced. A sealing bellows additionally provided can be designed to be very thin and weak, because of the ruggedness of the sealing means, so that the reset and control forces are thereby virtually uninfluenced. The control device is therefore particularly suitable for persons with low muscular power (drawing). <IMAGE>

Title: Method for controlling an embroidering machine and machine controlled according to the method
Inventor: WALLIMANN HANS
IPC: D05C5/04
Filed: 1988-10-26
Abstract: In the embroidering machine, in which the function commands for controlling it can be picked up from punched-card means (1) and are fed via needle tappets (2) to an automatic embroidering unit (3) which triggers the machine-function cycles via mechanical switching members, some of the function commands which can be picked up from the punched-card means (1) take effect as electrical control signals for a triggering of some of the machine-function cycles, especially the embroidering-frame positioning, the said triggering being independent of the automatic embroidering unit (3). The electrical control signals are present at the output of an electromagnetic converter (4) converting the mechanical movements of the needle tappets (2) sensing the punched-card means (1). This makes it possible, whilst preserving the mechanical triggering of existing individual functions of the embroidering machine by the automatic embroidering unit, to trigger predetermined machine-function cycles, such as, for example, the embroidering-frame positioning, electrically, any delay being avoided. <IMAGE>

Patent DE-3909685-A1 (DE)
Title: Method for frequency conversion, especially for communal satellite receiver systems, and associated frequency converter
Inventor: ILSANKER ANTON
IPC: H03D9/06
Filed: 1989-03-23
Abstract: It is possible, as is known, to transmit a plurality of programmes simultaneously using differently polarised waves via a satellite. After separating the different polarities, frequency splitting is then carried out using a diplexer. The total arrangement is, however, extremely cost-intensive. In addition, disruptive mixing products dependent on the local oscillator which deteriorate the signal received can occur. In order, in contrast, to produce a cheaper and improved method and an associated frequency converter, provision is made for at least one of the two frequency band ranges which are shifted with respect to each other to be converted in common to a lower intermediate frequency, and for frequency-range separation then to be carried out, in such a way that the allowable intermediate-frequency band range is already present in one cable and double conversion to the allowable intermediate-frequency band range is carried out in the other cable. The method and the frequency converter are particularly suitable for communal satellite receiver systems. <IMAGE>
