Title: Resistance seam welding machine
Inventor: STIEGER OTHMAR
IPC: B23K11/06
Filed: 1990-08-22
Abstract: ELPATRONIC AG, Baarerstrasse 117, CH-6300 Zug, Switzerland Case 89-145/CH          Switzerland Resistance Seam Welding Machine Abstract What is described is a compact resistance seam welding machine wherein the upper electrode roller (14) is provided on a pivotally mounted arm (12) instead of on a pendulum roller head.  The lower electrode roller (16), which is disposed below the upper electrode roller (14), is provided on a rigid lower arm (8) as usual.  The pivotal mounting (10) of the arm (12) consists of a stack of copper foils (102) on the side adjacent to the lower arm (8) and of a steel strip (101) on the side remote from the lower arm (8).  The steel strip (101) and the copper foils (102) are each clamped, on the one side to the machine frame (4) and on the other side to the opposite end of the arm (12).  The arm (12) is therefore pivotally mounted on the principle of a parallelogram linkage, while the pivotal mounting (10) serves for the transmission of welding current to the upper electrode roller (14) at the same time.  The pivotal mounting (10) only permits the upper electrode roller (14) a vertical movement up and down.  The construction described renders it possible to avoid an expensive pendulum roller head and to make the resistance seam welding machine more compact in construction without losing satisfactory guidance of the upper electrode roller (14) vertically and in the welding direction.

Title: Surgical needle configuration with five-sided cross-section
Inventor: WONG JOHN
IPC: A61B17/06
Filed: 1990-09-13
Abstract: A needle having three fluted edges, all of the same angular size.  The needle presents a five sided cross-section at a tapered end.  This results in easier tissue penetration, reduced cross-sectional needle area, better wound opening area performance, and minimized tissue distortion.  In an alternate embodiment, the flat surface from which the taper is formed is on the inside of the needle so that the outer fluted edges are formed outside that configuration.

Title: Continuous extrusion apparatus
Inventor: HAWKES DANIEL J
IPC: B21C23/00
Filed: 1990-05-18
Abstract: Apparatus for the continuous extrusion of metals in which feed is in-troduced into two (or more) spaced mart circumferential grooves (4) in a ro-tating wheel (2) (or rotating wheels) to contact an arcuate shoe portion (8) and abutments extending into the grooves. The feed is constrained by the abutments to flow through frusto-conical exit apertures (10) in the shoe por-tion (8) to a chamber (6) and is extruded as relatively thin-walled, large cross-section, product. The exit apertures (10) have cone angles in the range 5°-45°. Mixer plates (14) are profiled to distribute flow evenly from the ap-ertures ( 10) to around the die opening (30). An extrusion die body (18) for cylindrical extrusions is located and axially centered by set screws (122).    Where an even number of grooves (4) are utilised, an extrusion mandrel (12) may be secured to the shoe portion (8) by a bolt (22) positioned centrally of the grooves. Lubricant or oxidation inhibiting fluids may be injected inter-nally of the extruded product through a passage (36, 38) extending through the shoe portion (8) and the bolt (22). In another embodiment, the chamber (6) is also of divergent frusto-conical form having a cone angle correspond-ing to that of the apertures (10), thereby enabling the extrusion of even larg-er cross-section products. The frusto-conical form may be of elliptical cross-section to achieve a requisite divergence or to accord with the configuration of the die orifice. By providing spaced apart grooves (4) and apertures (10) diverging frusto-comically it is possible to extrude products of relatively large cross-section since the volume feed rate is enhanced and the distance travelled by the material from the grooves (4) to the die orifice (30) is re-duced, thereby reducing friction losses and the likelihood of discontinuities in the extrudate arising.

Abstract: ABSTRACT OF THE DISCLOSURE        A dielectric filter having a dielectric block made of a uniform.  single dielectric material.  dielectric resonators each of which includes a central conductor formed in the dielectric block in an approximately parallel fashion, and one or more coupling amount adjusting patterns each of which is formed between the two adjacent dielectric resonators and is grounded so that the dielectric resonators are coupled through inductive impedance.  The coupling adjusting patterns are formed on the top surface of the dielectric block in thin patterns.  This makes the filter smaller in size and the trimming of the pattern more easily than those of the conventional filters in the manufacturing process.  Control of the characteristics of the filter can be carried out easily.

Title: Method of manufacturing silicone rubber moldings
Inventor: SHIMIZU KOJI
IPC: B29K19/00
Filed: 1991-06-21
Abstract: A method for the manufacture of silicone rubber moldings comprises the preparation of a silicone rubber composition by blending an organoperoxide having an activation energy of 25 to 41 kcal/mol into a semicurable organopolysiloxane composition whose main component is an organopolysiloxane having organoperoxide-crosslinkable functional groups.  The silicone rubber composition is made into a particulate form and heated at a temperature below 100 degrees Centigrade to produce a semicured, particulate molding material which retains the activity of the organoperoxide and which contains residual crosslinkable functional groups on the organopolysiloxane. Subsequently a mold is filled with the molding material and the mold material is completely cured at a temperature of at least 100 degrees Centigrade under the application of pressure.  The method is particularly useful for automatic molding methods.

Inventor: DENT PAUL W
IPC: H03G7/00
Filed: 1991-08-20
Abstract: An amplifier/detector chain logarithmically amplifies an input signal as well as compensates for delays generated by necessary bandwidth restrictions. A plurality of amplifiers are connected in series and grouped in amplifier stages with each stage having at least one amplifier. In between each amplifier stage is a filter which restricts the bandwidth of signals to frequencies in a desired signal range. When an amplifier stage includes more than one amplifier, a local summer sums the outputs detected by detectors associated with each amplifier in a particular stage. When an amplifier stage includes only a single amplifier associated detector, the local sum signal for the stage is simply the detector output. No local summer is required. Because of the time delay introduced by each interposed filter, each local sum is input to a corresponding compensating device which compensates for the associated time delay. Each compensating device stores its corresponding local sum until the local sum from the final stage is ready to be output. When all of the local summer outputs have been time-aligned or brought in phase, the local sums are connected from their corresponding compensating devices to a central summer stage. The output of the central summer represents the instantaneous output of the logarithmically amplified input signal.

Title: Plasma source arrangement for ion implantation
Inventor: MATOSSIAN JESSE N
IPC: H01J37/32
Filed: 1991-09-23
Abstract: An object (14) which is to be implanted with ions is enclosed in a container (12).  A plasma (44) is generated in a chamber (26) which is separate from, and opens into the container (12).  The plasma diffuses from the chamber (26) into the container (12) to surround the object (14) with uniform density.  High voltage negative pulses are applied to the object (14), causing the ions to be acceler-ated from the plasma (44) toward, and be implanted into, the object (14).   Line-of-sight communication between a plasma generation source (30) located in the chamber (26) and  the  object  (14)  is  blocked,  thereby  eliminating undesirable effects including heating of the object (14) by the  source  (30)  and  transfer  of thermally  discharged material from the source (30) to the object (14).  Two or more  chambers  (26,34)  may be provided  for  generating independent plasmas (44,46) of different ion species which diffuse into and uniformly mix in the container (12).  The attributes of the different plasmas (44,46) may be individ-ually selected and controlled in the respective chambers (26,34).
