Patent DE-3545350-A1 (DE)
Title: Method and arrangement for suppressing the charging of a sample which is scanned by a corpuscular beam consisting of charged particles
Inventor: BRUNNER MATTHIAS DR
IPC: H01J37/02
Filed: 1985-12-20
Abstract: In order to improve the imaging properties of a scanning microscope attempts are always being made to prevent, or at least largely to suppress, the sample becoming charged. A solution of this problem is frequently additionally exacerbated if the secondary corpuscles released from the sample are sucked off the sample surface in a powerful external electrical field, in order to improve the signal-to-noise ratio. In order to suppress the positive charges induced by high suction fields, these fields are screened, according to the invention, with the aid of an electrode arrangement (AG) which is at earth potential, preferably a grid or mesh electrode, so that a space which is free of fields is produced immediately above the sample (PR). The secondary electrodes (SE) which pass through the plane of the grid are then additionally accelerated in the direction of the detector system (DT) but are no longer sucked off the sample (PR). In consequence, high positive charges are avoided. <IMAGE>

Title: Locking system for a vehicle door
Inventor: SONNEK GERD
IPC: E05B65/20
Filed: 1986-07-16
Abstract: The invention relates to a locking system with a lock cylinder (7) and a door lock which, in the locking position, can be secured against opening via a linkage arrangement (4, 5) by means of a door key or a door-securing knob. To improve break-in safety, it is proposed to assign to the locking system a blocking position, from which it can be freed again only by means of the door key. This can be achieved by means of a housing (1), in which, in one of a plurality of operating positions, a slide (2) connected to the linkage arrangement (4, 5) blocks the door-securing knob by means of a moulding (17) by pressing two bosses (27, 28), formed on a securing element (3) assigned to the door-securing knob, against a stop face (14). <IMAGE>

Title: Process and apparatus for producing ready-to-use adhesive
Inventor: STEIN OTTO A
IPC: B01F13/00
Filed: 1986-09-24
Abstract: For producing solvent or dispersion adhesives directly for use as and when required, the fluid used as the solvent or dispersing agent is pressed at elevated pressure and/or elevated temperature through a supply of basic material (5'), in solid or pasty form, whereupon the solution or dispersion is concentrated, homogenised and subsequently applied to the surface to be bonded. Serving for this purpose is, for example, an apparatus designed as a hand-held gun, the pressure vessel of which comprises two parts (11, 12) which can be screwed together. In front of the supply of basic material (5') there is a labyrinthal zone (17) and an application nozzle (9) with valve (10). Provided in the rear pressure vessel housing (12) is a connection nipple (13) for the fluid serving as the solvent or dispersing agent and also a pressure pump (16). The pressure pump (16) is actuated by means of a pivotable hand-operated lever (15). A fixed grip (14) serves as a steadying support. <IMAGE>

Patent DE-3703175-A1 (DE)
Title: Shield-type support
Inventor: NIEBUHR HERBERT
IPC: E21D23/04
Filed: 1987-02-03
Abstract: According to the present invention, existing stope supports are pressed against larger seam thicknesses by means of an intermediate box having loosely inserted prop stays. This configuration of intermediate box guarantees that the skid is not subjected to appreciably different load from that occurring in the basic construction of the shield without an intermediate box. Since the pull-back forces arising from the props are introduced directly into the intermediate box by the pull-back holders, the prop stays are fixed in the intermediate box without additional connecting elements.
Patent DE-3717760-A1 (DE)
Title: Device for coupling energy connections in the exchange and clamping of moulds
Inventor: ZACHARIAS FREDO DIPL ING
IPC: B29C45/17
Filed: 1987-05-26
Abstract: The invention relates to a device for coupling energy connections in the exchange and clamping of moulds in the mould space of an injection moulding machine, which energy connections can be produced between the clamping plate and the mould. The aim and object is to provide a functionally reliable and economical and universally applicable coupling connection which can be retrofitted and can be arranged laterally and at the end of the slide-in path of the mould. The object is achieved by using separate lifting cylinders which are flange-mounted, laterally of the slide-in path of the mould, on an intermediate plate, so as to be axially parallel to the clamping cylinder in their direction of action. For additional energy connections, further lifting cylinders on intermediate plates are attached to stop strips at the end of the slide-in path. Coupling strips are screwed onto the piston rods of the lifting cylinders and are guided in shaped parts. The coupling strips with the energy strips, which are attached to the adaptor plates of the mould via a connection part, are connected by a lifting movement of the piston rod. Fields of application are the production of energy connections in conjunction with the exchange of moulds, for example in the case of injection moulding machines. <IMAGE>

Patent DE-3728197-A1 (DE)
Inventor: LASSAL SAID
IPC: H02H1/00
Filed: 1987-08-24
Abstract: In an electronic protective relay, the feedback path of a comparator 22 with a feedback resistor 27 can be disconnected by opening switch 28 which resets the output of the comparator. On a release by an operational amplifier 20 coupled to a fault detector, a capacitor 23 is charged and the comparator 22 switches over. When the operational amplifier 20 switches back, self- holding is ensured by the resistors 27, 21. As a result of actuation of the switch 28, the self-holding is released and the capacitor 23 is discharged through a Zener diode 25. In the event of failure of the supply voltage, the capacitor 23 remains charged and prevents immediate reconnection. <IMAGE>

Title: Tong trolley belt conveyor
Inventor: RAPPEN ALBERT DIPL ING
IPC: B65G15/08
Filed: 1987-11-14
Abstract: In belt conveyors having a conveyor belt which, on a part of the conveying section, has a closed tube shape and is supported and held together by stationary belt support rollers, large forces are to be transmitted in the belt as a result of high prestress and flexing resistances. As a result of high belt tensile stresses, the curve-going ability is limited and high drive powers are required. Using the novel belt conveyor, a more gentle treatment of the conveyor belt and thus a longer service life are to be achieved and a significantly smaller drive power is to be required without the transport capacity decreasing. The novel belt conveyor is characterised in that one or both tong arms (22, 23) of every tong trolley (2, 2') can be swivelled about axes extending in the conveying direction outside a vertical central plane and that, in their closed position, they enclose the tubular conveyor belt (10) while partially overlapping each other. As a result of this configuration of the tong trolley, the tubular conveyor belt is grasped, held and released again both gently and securely. The belt conveyor is suitable for the transport of any desired bulk materials, in particular in mining. <IMAGE>

Title: Vacuum switching tube
Inventor: PECHE GERHARD DR
IPC: H01H33/666
Filed: 1988-01-29
Abstract: Previously known vacuum switching tubes having two stationary contact elements and one moving contact element located between them and bridging them are not suitable for heavy currents and high voltages as a result of the geometric arrangement of their contact system, it also being necessary to exert a high contact force continuously on the moving contact element in the connected state, by means of an externally arranged drive, in order to avoid said contact element lifting off in the event of short-circuit currents, in the case of which event there is a risk of the contacts welding. In the case of a vacuum switching tube having a contact system (3) which is located in a housing (1) and consists of two stationary contact elements (6), which are opposite one another, and a moving contact element (8) which is located between them and bridges them, an electrical power supply in the form of a loop is formed by the V-shaped arrangement of the stationary contact elements (6), which are combined with high-voltage bushings (7) to form coaxial, vacuum-tight structural units (23), in the case of which power supply the current forces counteract the stationary contact element (8) lifting off, even in the case of heavy short-circuit currents, so that, overall, high voltages and heavy currents can be switched and, at the same time, the cost for mounting and driving the vacuum switching tube is only low.
