Title: Equipment for changing test glasses for the optical measurement of the characteristics of layers in vacuum-coating equipments
IPC: G01N21/25
Filed: 1986-12-03
Abstract: Test-glass changer for measuring layer properties optically in vacuum coating installations. A holding device (10) that accommodates several test glasses (12) is rotatably supported on a substrate holder (4), which serves to transport substrates (5) through a stream (22) of coating material.

Patent EP-0201992-A3 (EP)
IPC: B05D3/06
Filed: 1986-03-13
Abstract: Method for the coating of a substrate under vacuum 
conditions firstly with non-oxidized plating material 
(108) which is deposited on the substrate (100) via ion 
vapour deposition; and secondly with a coating material 
(112, 114) is chemically bonded with the non-oxidized 
plating material. The coating material may comprise a 
primer (112), which chemically bonds with the 
non-oxidized plating material (108), and a polymer (114) 
which impregnates the primer-prepared plating material. 
Said polymer (114) may also chemically bond with the 
primer (112). Alternatively, the coating material may 
comprise an epoxy which forms an organo-metallic bond 
with the plating material. The coating material may also 
comprise boron trifluoride, which chemically bonds with 
the non-oxidized plating material, and a polymer, which 
impregnates the boron trifluoride-prepared plating 
material. Alternatively, the coating material may 
comprise calcium, silicon, and oxygen which chemically 
bonds with the plating material. The coating material 
may be bifunctional, in that it not only chemically 
bonds with the plating material but also bonds with a 
second coating material, yielding a chemically bonded 
uniform coating with desired results.

IPC: F24C7/00
Filed: 1986-05-15
Abstract: An electrical heating appliance, e.g. a radiant fire, has 
manual switches which can be by-passed to allow for remote 
control. A hand-held controller (27) produces a beam of 
infra-red energy which impinges on a sensor (26). Control 
box (24) receives command signals from sensor (26) and 
carries out an appropriate switching operation. The control­
ler (27) has slider switches (29, 30, 31) for selecting the 
desired heating appliance mode of operation, but these are 
ineffective until pressure switch (28) is pressed to produce 
the beam.  
     An alternative arrangement has the sensor distant from 
the heating appliance.

Title: Detonator actuator
IPC: F42D1/055
Filed: 1986-06-26
Abstract: An actuator for use in conjunction with a detonator for blasting comprises electronic circuitry which on receiving input signals generates an output arm signal to arm a detonator, and then after a predetermined delay an output actuate signal to fire the detonator and an associated explosive charge. The delay is capable of being remotely and precisely set. The actuator is preferably used in conjunction with a control device which has a microcomputer whose memory contains arm and actuate codes and which has both arm and actuate keys. This microcomputer is such that the actuate key must be operated within a predetermined period after operation of the arm key, otherwise an actuate signal is not transmitted to the actuator.

Patent EP-0265785-A3 (EP)
IPC: C07K19/00
Filed: 1987-10-15
Abstract: The baculovirus-insect cell vector system is used as a 
high efficiency eukaryotic cloning and expression method 
for the production of recombinant proteins. A major 
application of this system is also in the development of 
rDNA vaccines for a variety of important human and 
animal diseases. This system is used to express a 
variety of candidate vaccine immunogens derived from the 
envelope gene of Human Immunodeficiency Virus (HIV). 
The envelope protein of HIV is the most promising 
candidate in the development of vaccines and diagnostics 
for AIDS since it has been shown that the envelope 
glycoprotein represents the major target antigen of AIDS 
virus. Recombinant baculoviruses have been constructed 
which express a variety of domains of the envelope gene 
( env ), including gp 160 and gp 120. Expression of the 
recombinant HIV baculoviruses in insect cells results in 
the production of glycoproteins which are reactive with 
HIV-specific serum. HIV antigens produced from some of 
these recombinants have been successfully employed in a 
variety of immunodiagnostic assays including ELISA, 
Western Blotting and radioimmunoprecipitation.

Title: A method and an arrangement for the sterilization of a filter
IPC: B65B55/02
Filed: 1987-06-25
Abstract: Filters for the supply of inert gas to packing machines are sterilized by passing steam and sterile air through the filters via a number of ducts, valves and governors. A simpler method for achieving the sterilization is obtained by sterilizing the filter (11) jointing with the packing machine which may be done by connecting one side of the filter in series to the circulation system of the machine for sterilization by means of chemical sterilizing agent. In this way the abovementioned arrangement is simplified considerably in that a large number of valves and ducts becomes superfluous.

IPC: H01Q21/00
Filed: 1987-05-11
Abstract: A vehicle (1) includes a radar antenna (12) mounted 
in a nose portion (10) of it. The antenna (12) is shaped 
substantially to conform to the exterior contour of the 
nose portion (10) and has a surface angled with reference 
to the forward direction and hence to the expected 
direction of incident emission from a threat radar so 
that the emission is deflected away from and not returned 
to its source. This reduces the forward hemisphere radar 
signature of the vehicle which is the dominant signature 
as far as an enemy radar is concerned to a considerable 
degree.

(14) having a second rotatable spindle (18) carrying a 
respective workpiece gripping device (18 a ) the 
headstock (14) being presented towards the headstock 
(12), and being relatively movable towards and away

Title: Wire-rolling mill
IPC: B21C47/26
Filed: 1988-08-03
Abstract: A wire-rolling mill having a plurality of roughing stands, a cropping shear, a finishing block, a loop layer with a laying pipe and having a drive comprising a loop-layer motor and a loop-layer gearbox and having a discharge conveyor for the finished rolled wire laid out in loops, these parts of the installation being arranged in series in the running direction of the wire. The wire-rolling mill has a control device with a computer, the computer controlling the cropping shear in accordance with a predetermined rolling program by means of a computer cutting command. In accordance with the computer cutting command, the cropping shear cuts off a certain length from the beginning of a wire strand before it enters the finishing block. It thereby produces the head of the wire to be laid out in loops. The cropping length is matched to the position of the loop layer. The loop layer is provided with an angular position sensor, which operates with digital pulses and is connected to the control device and the annular positions of which correspond to the positions of the laying pipe. The control device combines the computer cutting command and digital pulses of a predeterminable laying-pipe position sector by means of an electronic AND circuit to form a position cutting command, the cropping shear thus responding only to the position cutting command.

Title: Backwash filter
IPC: B01D35/16
Filed: 1988-08-26
Abstract: In a backwash filter, a filter insert, with its outside adjoining a backwash channel (17) extending parallel to the axis thereof, is rotatably mounted in a housing which has a cylindrical inspection window (2). The surface of the filter insert can be moved past the backwash channel (17) by rotating the filter insert by means of a handwheel (10). The inspection window (2) is intended to allow the state of the filter insert to be observed. It is found, however, that such an inspection window very quickly loses its transparency due to condensation or solid growth. According to the invention, a screen wiper (21) is fixed to the rotatable filter insert and, on backwashing, is moved across the cylindrical inspection window (2) by rotating the filter insert and thus effects cleaning thereof during each backwash. By means of a recess (22) next to the screen wiper (21) in a flange (14), which bounds the chamber (28) containing the screen wiper, a connection can be made during backwashing to the backwash channel (20) which allows the extraneous bodies removed from the inspection window (2) by means of the screen wiper (21) also to be washed out. <IMAGE>
