Patent EP-0081097-A2 (EP)
Inventor: WOEHRSTEIN EDWIN
IPC: F41B11/62
Filed: 1982-11-12
Abstract: In a CO2 firearm, the connection for the CO2 capsule is connected directly to the barrel, and the non-return valve of the CO2 capsule is used directly as a valve for proportioning the gas quantity to be introduced into the barrel for firing. The striker of the firearm therefore acts directly on this valve, if appropriate via a tappet. A CO2 capsule designed for use in such a firearm has as a non- return valve a disc valve which is brought into the closing position and held therein solely by the gas pressure. An adaptor for connecting such a capsule to a supply bottle can contain a sealing body which essentially fills the connection piece of the supply bottle in order to keep the dead space between the valve of the supply bottle and the non-return valve of the CO2 capsule as small as possible. The striker acting directly on the non-return valve of the CO2 capsule can be arranged such that, before striking against the tappet for opening the non-return valve, it is released by the striker spring which previously comes to bear against a stop fixed to the housing. A detent member, preferably in the form of a slide, can then also be arranged in the path of the striker and catches the striker before it comes up against the tappet, in order to allow training as near to actual conditions as possible. Finally, such a CO2 firearm can be equipped with a vertically adjustable sight, in which a pivotably mounted sight carrier is supported on a wedge piece which is transversely adjustable by means of a setscrew and which is itself supported by means of an oblique surface on the obliquely cut-off end of the leg of a leaf spring which is bent in the form of a U and the other leg of which acts on the sight carrier and presses the sight carrier via the wedge piece against the supporting part formed by the leg of the leaf spring. <IMAGE>

IPC: G07F7/10

Abstract: A pay or credit card (A) is inductively coupled to a data transfer programming and processing and display unit (B) which in turn is coupled via inductive coupling links (2b-2c, 3b-3c) to a third unit (C) which comprises mostly miniaturized circuitry such as more particularly storage registers (31) for two «wrong» security check numbers and four «right» such numbers and auxiliary logic circuitry, as also a transaction list memory (63). The latter may be constituted as a fully sealed tape unit with built-in stepping motor and solid-state comparator circuitry. The said security check numbers are received and from time to time updated via inductive coupling links (2d-2e, 3d-3e) from a main transaction office (D) such as a bank, credit card office, etc, and, during a card transaction, responsive to a reference number emitted by the card, selects one or more of the «right» numbers and a «wrong" number. The automatic sequence changer circuit (32) presents to the card an unpredictable sequence of the selected numbers and then tests the card reaction to this input, in a response evaluator circuit (33). The test and transaction list unit (C) would be optional at a card terminal and required only at off-line stations (f.e. for smaller traders and vending machines where separate data lines to banks would not be economical).Where on-line operation is possible, the bank computer (D) would perform the check operations of unit C. Accordingly, the bank computer (D) would communicate during day time with cards (A) via processors (B) which belong to on-line terminals, while during night time and early morning hours the accummulated off-line transactions are received from test and transaction storage unit (C) via a modem (D'), when also the cyclically required modification of one of the registers (31) is performed. The Bank Computer (D) itself receives from time to time modification instructions for its security check number register via interbank data lines from Bank Head Office. The Head Offices of different banks receive similar data from a single random data generator or clearing bank director respectively. A card processor for unpredictable sequence of right and wrong test numbers has first been described in British patent application 79 31 208, and is here presented as a complete card data and regional transaction transfer security system.

Abstract: A continuous strip (30) of puncture sealing material is applied to an inside surface of a tire (10) by laying and adhering a plurality of side-by-side turns of the strip (30) with the different turns (32,42,54,70) connected by angular crossing portions (38,48,58) in the area of a first circumferential position (36) of the tire (10). The first crossing portion (38) overlaps a first end (34) of the first turn (32). The other end (74) of the strip (30) is tapered and overlaps the last crossing portion (58) and a portion of the last turn (70) of the strip (30). The first circumferential position (36) of the tire (10) may be at a light spot circumferentially of the tire (10) for improved balance of the tire (10). By overlapping the edge (44,46,62,64,76,78) of the strip (30) and pressing the material against the tire surface (28), the resulting puncture sealing layer (26) is continuous and completely covers the surface (28) of the tire (10) under the crown portion (18) for protection against punctures due to nails and other sharp objects.

Abstract: Odontological prostheses are produced from acrylic resin using cast plaster impressions confined in a closed, 3 plate metal mould by using a two stage press tool, for one stage of which the platens are heated to raise the mould temp. to between 100 and 135, pref. 110-115 deg.C, the other stage being chilled to 15-20 deg.C to subsequently cool a mould transferred from the hot stage while maintaining clamp contact. Process produces mouldings more quickly and to a higher level of hardness than processes in which the mould temperatures are limited to about 100 deg.C, e.g. by simply placing clipped moulds in a bain-marie.

Filed: 1983-03-30
Abstract: Die Entkopplungsvorrichtung wird zum Verbinden von zwei Stangen, insbesondere von den zwischen Getriebe und Schalthebel eines Kraftfahrzeuges angeordneten Schaltstangen, verwendet. Durch diese Vorrichtung wird nach dem Einschalten eines Ganges eine Hin- und Herbewegung der entkoppelten Schaltstange ermöglicht. Dadurch ist bei eingeschaltetem Gang die starre Verbindung zwischen Schalthebel und Schaltgetriebe unterbrochen. Eine formschlüssige Verbindung zwischen den beiden Schaltstangen wird nur dann hergestellt, wenn ein Anwählen des Ganges oder ein Aus- oder Einschalten des Ganges erfolgt. Die durch die Entkopplungsvorrichtung bewirkte Unterbrechung der Verbindung zwischen Schalthebel und Getriebe verhindert ein unerwünschtes Gangspringen. Bei der Entkopplungsvorrichtung ist zwischen den in Eingriff miteinander stehenden und in einem Rohrstück (4) gelagerten Enden der Schaltstangen (1, 2) ein den Entkopplungsvorgang steuerndes, verschiebbares Zwischenstück (3) angeordnet. Das Zwischenstück (3) ist auf einer Zunge (5) der einen Schaltstange (1) gelagert und besitzt ein Entkopplungselement (21, 41), das mit Vertiefungen (22, 23) in der Zunge (5) und/oder der Nut (6) der Schaltstangen (1, 2) zur Hertsellung einer formschlüssigen Verbindung zusammenwirkt. Weiterhin der Zwischenstück (3) mit einer Rasteinrichtung (11) versehen, die in Vertiefungen (17, 18, 19) des die Enden der Schaltstangen (1, 2) umgebenden Rohrstückes (4) einrastet. Auch eine kraftschlüssige Kopplung der beiden Schaltstangen ist möglich.

Abstract: 57 Under particular conditions, a cationic ring-opening polymerization of a first oxirane monomer selected from the group consisting of an acyclic glycidyl ether, a cyclic glycidyl ether, and a haloalkyl epoxide, in the presence of a hydroxyl-containing organic material ("HCM"), for example a polymer (referred to herein as a "hydroxyl-prepolymer"), and a particular catalyst, produces a polymerization having "living polymerization" characteristics. The result is that molecular weight (mol wt) of the resulting polymer is directly proportional to the conversion of the monomer to said resulting polymer. This HCM serves as a chain propagator which initially furnishes OH groups as propagation sites. Subsequently, a second oxirane monomer, different from said first, is sequentially polymerized to yield a block copolymer. Branched block copolymers, or linear block copolymers of a HCM and (a) one or more glycidyl ethers, or (b) a haloalkyl epoxide and at least one glycidyl ether, may be prepared. Halogen containing segments of the block copolymers of the invention may be aminated to produce amphophilic polymers.
