Title: Mobile grooved roof sealing sprayer auxiliary device - with flat-bottomed skid and top detachable holders keeping interval from wheels
Inventor: GERSTER XAVER
IPC: E04D15/07
Filed: 1974-04-24
Abstract: The object is to adapt a spraying assembly, mounted on a mobile carriage and used for spraying sealing and covering materials onto roof surfaces, with the aid of an auxiliary device, so that its application to grooved surfaces, such as roofs covered with trapezoid sheeting, is simplified. This incorporates a skid, with flat smooth lower surface and with holding devices fitted at the top, permitting detachable fitment to the carriage in such a way that the carriage wheels are retained at a vertical interval from the underside of the skid. The latter may have a yoke pole at one end, which is a rigid bar, attached to it by means of an all-round adjustable hinge. This is easily produced, serviced and handled, without any need for the wheels to plunge into the grooves.

Title: Hydraulic buffer with membrane for shuttle of loom - with increased durability providing reduced malfunctioning of loom
Inventor: HAAG WALTER
IPC: D03D49/38
Filed: 1975-04-18
Abstract: Hydraulic buffer for cushioning shuttle entering loom comprises between an oil housing and an air housing a membrane in the form of a folded bellows member which is closed on side and which has >=2 fold points. The bottom of the membrane, which is pref. made of a polyurethane elastomer, may be thicker towards the centre, which is easily arranged by injection moulding and which allows deformation with increased durability. The reinforced edge of the membrane is clamped between the oil and air housings. After a given loss of oil, the membrane is slightly curved towards the oil side in its neutral position, which reduces max. deformation and therefore stress on the membrane when the piston is displaced into the oil housing.

Title: Safety casing for nuclear steam generator - has conical base carrying vessel with outer ring and vertical ties
Inventor: MUTZL JOSEF DIPL ING
IPC: G21C9/00
Filed: 1975-10-13
Abstract: A burst steam generator sagety device consists of a casing surrounding the steam generator and comprising series of cylindrical wall sections or strakes placed one above another, a top closure and a bottom closure. The entire assembly is longitudinally (vertically) connected together by elements which accept axial tension. The bottom closure is constituted of a conical shell, its narrow end upwards and towards the heat exchanger, while its outer, lower wide end terminates as a support ring connected to the vertical ties or cables. The weight of the pressure vessel rests upon the narrow end and is transmitted through the conical portion to the ring. The device is esp. used for the steam generating units of a pressurised water reactor power plant. The arrangement enables a considerably lighter bottom closure for the burst protection device to be constructed than a conventional solid bottom closure.

Title: Ice skate blade assembly - has side wall elements running upwards from blade mount and screw studs which fit into top flange holes
Inventor: VAIKIE HUGH E
IPC: A63C1/32
Filed: 1976-03-29
Abstract: The ice skate has a blade assembly (10) consisting of a pair of side wall elements (11, 12) which run upwards from a runner mount (13) and having an outward flange (14) at the top. The shoe is provided with set in screw studs which correspond with holes in the top flange (14) by which the runner assembly (10) is fixed, by nuts (28) to the shoe. The blade (15) is welded or soldered into a mounting (13) at the base of the walls and the running edge (15a) of the blade is curved to improve stability. The ends (20) of the runner are rounded as are the ends (22, 23) of the walls thus avoiding the formation of sharp corners which can be dangerous to the user and/or other skaters. This provides a skate whose blade can be easily replaced when it is worn out or broken. In another variation the boot and blade assembly can be made in one piece of plastic material.
Patent DE-2619802-A1 (DE)
Title: Flexless ultrasonic soldering of capillary joints - with simultaneous solder bath cavitation and vibration of part to be soldered
Inventor: ANTONEVICH JOHN N
IPC: B23K1/08
Filed: 1976-05-05
Abstract: Capillary joints are soldered by immersing the part to be soldered in a molten bath of solder and causing the solder bath to cavitate while simultaneously subjecting the part to vibratory or impact energy separate from the solder bath cavitation. After a period of time the energy causing cavitation is terminated and the part is withdrawn from the bath while subjecting it to continuing impact or vibratory energy. Used for fluidless ultrasonic soldering of return bends to bells of Al air conditioning coils. The combination of cavitation with vibration or impact of the parts to be soldered reduces the energy requirements for soldering, eg. air conditioning coils can be made in about half the time conventionally used using 50 and 90% less power in conventional plane standing wave and focused field solder pots resp. There is a redn. in the incidence of aggregation of resonant vaporous or gaseous cavities on surfaces thus reducing localised pitting of solder surfaces.

The arm has two twine guides at the end which are spaced in the arm swivel plane by an amount as large as the pitch of the turns of twine round the bale. The arm has a guide stay at the end which lies in the swivel plane of the arm and carries the guides. After passing round the bale, the two twine strands are severed by a common cutter. The guides may be adjustable sideways on the arm.

Title: Magnetron having cylindrical housing with radial segments - is made from continuous tape folded back on itself at regular intervals
Inventor: FRITZ KARL DR
IPC: H01J23/16
Filed: 1976-10-18
Abstract: The magnetron can be manufactured simply in any size using solely punch, draw and bending processes and with a reduced overall length of welding seams. It consists of a cylindrical housing closed at both ends to form a vacuum chamber. Inside segments extend radially and are connected together alternately by circular conductors and by the housing. The cathode is in the centre. The segments (4) are made of a continuous conducting tape folded through (180 deg. at the radially innermost end (to form the segments) and through 90 deg. at the radially outermost ends (to join with housing). The tape thereby travels over the curved inside surface of the housing between those parts of it forming the radial segments.
