Title: Loom shuttle - with a seat for retaining a support spindle of a weft yarn package
Inventor: MEYERING OTTO
IPC: D03J5/00
Filed: 1973-03-05
Abstract: A loom shuttle is formed in two parts and includes a cavity in which a weft yarn package is carried and a seat at the end of the cavity in which a foot of the support spindle of the package is retained. A slot connects with the seat to allow the two parts of the shuttle to be separated whereby the spindle foot can be located in the seat, and a resilient fixing plate is located in a transverse aperture in the shuttle in the region of the slot to prevent subsequent relative movement between the two parts. The fixing plate lies in the median plane of the shuttle, and one end has a thickened flange which locates in a recess in the aperture whilst the other end is apertured to receive a retaining pin which passes through the shuttle. The arrangement is simple and allows rapid replacement of the weft yarn package.

Title: Formation of pipe with helical seam from metal band - involves use of edge trimmers parallel to band axis to ensure fixed width of band entering welding machine
Inventor: BLUME HELMUT DR
IPC: B21C37/12
Filed: 1973-06-18
Abstract: The band is fed to the welding machine by means of rollers and its edges are trimmed by shears and milling or planning machine cutters are located on both sides of the strip. The angle of lay of the band for pipe welding is controlled by the fixed position of guide rollers in relation to the axis of the formed pipe. Elimination of the bow information during trimming is achieved by providing a greater allowance in machining the rough edges, the loss of metal compensated by fixed angular setting.

Title: Bobbin doffing device for a yarn winding mechanism - is driven by piston of double acting pneumatic ram
Inventor: OPEL DETLEF
IPC: B65H54/52
Filed: 1973-10-12
Abstract: A bobbin daffing mechanism of a winding mechanism is driven by pref. longitudinal movement of a drive shaft connected to pref. an independent piston located within a cylinder of a ram, the cylinder also pref. incorporating an auxiliary piston mounted on a lay shaft whereby when the cylinder air is introduced through an inlet between the auxiliary piston and a wall within the cylinder the cylinder is moved such that pref. a rubber stop on the lay shaft abuts against a seat in one end of the cylinder, and the independent piston moves until pref. an abutment on the drive shaft engages a stop at the opposite end of the cylinder. In this position the drive shaft maintains the bobbin in the winding position to doft the bobbin air is introduced through an inlet between a second auxiliary piston and the wall to move the cylinder such that the rubber stop disengages from the seat, and this air is then transferred through a vent and an inlet to the space between the end of the cylinder and the independent piston thereby causing longitudinal movement of the drive shaft to doff the bobbin. In certain cases springs may be used to effect movement of the drive shaft or cylinder.
Patent DE-2356734-A1 (DE)
Title: Furniture hinge type connector - is moulded from plastics by using inserts for direct forming of pivoted joints
Inventor: SCHNELLE MANFRED
IPC: E05D3/06
Filed: 1973-11-14
Abstract: The plastics components of the hinge which are used to reduce wear in the pivoted joint are made integrally. The inserted pivoting pins are used to ensure good rotating characteristics and positive fastening of the plastics components themselves. The manufacture of the components on using integral design of a number of individual components is made cheaper. The components can be produced by injection moulding because no complicated sliding components are used in the moulding die for forming pivot seats. This simplifies the design of the injection moulding dies. The plastics hinge pins are made separately. The wide angle hinge has housing with two bearing pivoting pins and two levers are pivoted on these pins. The hinges can also be made from metal in which case plastics material bearing elements with sockets and pins are used.
Patent DE-2357652-A1 (DE)
Title: Travel time of control elements monitoring circuit - is operated by control commands and feed-back signals giving final position of element
Inventor: MEIER WERNER
IPC: G08C25/02
Filed: 1973-11-19
Abstract: There is a delay line generating direction signals and a travel time starting signal for a delay stage. Direction oriented travel time starting signals are applied to the delay line inputs; two gates form direction oriented travel time signals by conjunctive linking of the delay stage output signal with a direction signal. Two gates form the above direction oriented travel time starting signals by conjuctive linking of a directional control command with the corresponding feed-back signal; and the delay line has two delay elements started by the direction oriented travel time starting signals; they deliver directional signals whose delay times correspond to the delay stage recovery time. An OR gate links the directional signals into a travel time starting signal for the delay stage.

Title: Mechanical hay-rake fixed to front of tractor - has finger-wheels positioned obliquely to direction of travel, and can be lifted for transporting
Inventor: KRAFT WOLFGANG
IPC: A01D78/00
Filed: 1973-11-28
Abstract: The hay-rake consists of a support arm at each side supported at each end by a wheel. The inside ends of the two support arms hinge on roughly vertical axes onto a mounting which is pivoted on a vertical bearing pin at the front end of the tractor. Two finger-wheels pivot freely on approximately horizontal axes on each support arm. They are driven by the tractor engine and convey the hay towards the middle. Both support-arms are joined by an elbow lever expanding rod which is connected to the implement arm by means of a connecting rod. The support arms can be closed together for transporting, and are splayed out when in operation. The implement arm supporting the rake can be raised and lowered.

Title: Sheathing concrete wall wood-fibre panel formwork - withspacers incorporating two wire loops each embracing panel and edge timber
Inventor: WILDENAUER RICHARD
IPC: E04G17/14
Filed: 1974-02-01
Abstract: Closed spacers are fitted, at an interval from the main ceiling, with two wire loops pointing upwards determining the spacing of the form panels, and extending far enough outwards for each to fit closely round a panel and an edge timber. Spacers with wire loops pointing upwards and downwards are then laid on top of the panels, and a longer edge timber is inserted in the superimposed spacer ends from above. After the bottom form unit has been filled with concrete and this has set in the spaces between the edge timbers and the upward pointing loops, the process is repeated with a second row of form panels inserted, and concrete is cast into the intervening space formed by the panels. The process is continued up to ceiling height. Very smooth concrete walls can be erected.

Title: Compressor valve with spring leaf closure member - has bending strength reducing from fixing point to free end
Inventor: MUELLER WOLFGANG DIPL ING
IPC: F04B39/10
Filed: 1974-02-27
Abstract: The valve intended as a suction or pressure valve for a compressor and has a resilient leaf secured at one end, the other end of the leaf serving to cover or uncover the gas ports. The resistance to bending of the lead reduces from the secured end in the direction of the free end and a space is provided which permits un-impeded opening movement of the free end. The bending strength pref. reduces progressively, which may be achieved by a gradual reduction of the thickness of the leaf or by a combination of reducing thickness and changing width.
