Patent CH-669340-A5 (CH)
Inventor: STIEFEL JAKOB
IPC: B02C18/14
Filed: 1985-07-17
Abstract: Two rolls which carry roll teeth rotate, as seen from their top side, in directions away from their common roll nip or gap towards adjacent hopper wall sections which carry hopper teeth. The refuse is thus loosened instead of being compacted in the common roll nip or gap, as in the prior art. The loosened material is more readily cut than the material which hitherto was compacted in the common roll gap. At a predetermined limiting load between the roll teeth and the hopper teeth, at least the hopper wall section which carries the affected hopper teeth, is retracted from the associated roll by a drive and from its operative position depicted on the right in FIG. 2 into an inoperative position depicted on the left in FIG. 2. The interfering material can fall through downwardly, whereupon the hopper wall section returns towards the associated roll into its operative position. No hopper blockage can occur.

Title: Vehicle saddle cover, designed for use with any type of vehicle fitted with a saddle
Inventor: STAUFFER ERIC
IPC: B62J1/20
Filed: 1993-12-02
Abstract: The saddle cover consists of a layer of an impermeable material (8) which fits inside a holder (2) and can be deployed over the saddle (1) to keep it clean and dry. The cover has a fastener (3) e.g. with a button, press stud, hook or hook and loop pile fabric to hold it in the deployed position, and cords or lines (7) which wind onto rollers inside the holder to retract the cover when the fastener is released. The cords or lines pass through holes in curved frame members (6) which hold the cover across the saddle.
Patent CH-659384-A5 (CH)
Title: Welding mask
Inventor: BARTOLINI PIERO
IPC: A61F9/06
Filed: 1984-08-29
Abstract: The mask comprises a member generating a jet of air in the direction of the location of the weld. This member consists of an electrical blower (3) similar to a hair dryer, fixed to the inner face of the protective screen (1) and acting as a handle for supporting the mask. The blower sucks air from the inside of the mask through suction orifices (6) and it ejects a jet of air through an orifice (8) made in the screen (1) below the observation window (2). The electrical supply may be provided by the 220 volts mains or with low voltage by an electrical welding unit. Such a mask makes it possible to improve the visibility for the welder by blowing away smoke and gases and keeping the glass mounted in the window clean. <IMAGE>
Patent CH-659434-A5 (CH)
Title: Tyre chain
Inventor: KLOPFER WALTER
IPC: B60C27/10
Filed: 1982-08-30
Abstract: The tyre chain has an inner part (2) with fastening links (9) which are provided on a respective end (7, 8) of two sections (5, 6) of a fitting bow (4). Provided on the other end (24) of one fitting-bow section (5) is a coupling link (30) to which one end (51) of a tensioning part (31) is connected. The other fitting-bow section (6) has, at the other end (25), a first deflection guide (32) for the tensioning part (31) which runs over the running part (1) up to the outer part and through a second deflection guide in the outer part. The fastening links (9) are provided on the ends of the fitting-bow sections (5, 6) which face away from each other, and form the joint of the two fitting-bow sections (5, 6). After opening the fastener (9), the tyre chain can be folded up very small. Due to the fastener (9) which can be opened, the tyre chain can be simply pulled onto the tyre and tensioned without moving the vehicle. The tensioning part (31) can be operated from the outer side of the wheel, with the result that the inner part (2) and the outer part (3) can be tensioned from the outer side of the tyre or wheel. <IMAGE>

Title: Drive gear suspension for vertical sand grinder - has resilient blocks incorporated in three-point suspension system
IPC: B02C17/18
Filed: 1975-04-23
Abstract: The sand grinding machine is for separating lumps of foreign matter from the fine grains of the sand. It has a vertical cylinder divided horizontally into compartments, with blades supported on a vertical spindle rotating inside each compartment, a feed chute at the top and a delivery chute at the bottom. The drive gear at the top is connected onto the top of the spindle. This drive gear has its base-plate mounted via a three-point support on the top of the cylinder. Each of the three supports is designed to reduce vibration, and has a resilient block secured between an upper and a lower angle bracket. Each bracket has a horizontal face and face at 45 deg. to it, with the block between. Thus the lower bracket is spaced further outwards than the upper bracket, and the arrangement tends to prevent the spindle from sloping from the vertical.
Patent CH-644907-A5 (CH)
Title: Textile machine for producing a textured yarn
Inventor: BAUER KARL DR
IPC: D02G1/16
Filed: 1981-08-31
Abstract: The texturing machine confers protruding rings, loops or the like on the individual filaments of a synthetic continuous multifilament yarn in a compressed-gas jet. The jet is located between feed rolls. The downstream feed roll is followed on its downstream side by a singeing means which opens the rings, loops or the like in such a way that there remain protruding individual fibres of a length to be predetermined. The singeing means can be located upstream or downstream a heat-setting heater. Upstream of the singeing means there can be located a special fibre finish applicator or a false-twisting device. The singeing means can also be located within a stabilising zone.

Title: Printing mechanism, preferably for a label printing device
Inventor: GSCHWIND MARIO
IPC: B41K3/08
Filed: 1978-06-07
Abstract: The printing mechanism (4) preferably intended for label printing devices has type-carrying wheels (18.1, 18.2) which bear printing types and are connected to one another via hollow shafts (24-26) inserted coaxially in one another with adjusting wheels (19.1, 19.2) to form individually adjustable units. A plurality of such units are combined to form an assembly. The hollow shaft located in the outermost position on such an assembly is mounted rotatably on a carrier (20) of the printing mechanism while the units located radially on the inside are mounted in each case on parts of the respectively adjacent unit with the hollow shaft located radially on the outside. The bores of the hollow shafts are spaced away from the surfaces of the adjacent hollow shafts, said surfaces being ground precisely over their entire length. The ends of the hollow shafts protrude in each case into central blind-bore hollows in the type-carrying and adjusting wheels and are anchored there fixedly against rotation. The bore of the central hole of the type-carrying and adjusting wheel is selected and treated in such a way that it is able to form a bearing point (31, 32; 33, 34) with the surface of the adjacent hollow shaft. <IMAGE>

Title: Gas pressure regulator with secondary seal - has coaxially mounted seals for orifice both moved by diaphragm linkage
IPC: F16K17/04
Filed: 1973-10-30
Abstract: The gas flows into the valve body through the vertical sealing passage, and out through the opposite exit. Mounted on top of the valve body is the hollow control chamber with, mounted centrally, a sealing membrane. Mounted below the membrane is a spring loaded multiplying linkage connected to a hollow push rod supporting a primary valve over the sealing passage. Mounted above the membrane is a latched spring loaded bar passing through the hollow push rod to a safety valve beneath the seal. If back pressure occurs, gas is fed through a control tube, under the membrane, operates the linkage, and seals the primary valve. Should this fail the using membrane trips the secondary valve stem and raises the secondary safety seal.
