Title: Bowl-shaped item pneumatic conveyor - has air jets inclined to cage structure forming passage
Inventor: MORINI RINO
IPC: B65G51/02
Filed: 1977-04-09
Abstract: The pneumatic conveyor transports bowl-shaped items from a dispensing to a receiving machine, being partic. for handling screw caps. The items are transported along a passage (1) of cage-type structure between the machines, and there are a number of jets (11) at points along the passage, supplied from a compressed-air source. These are inclined to the passage, so as to produce currents of air with a component in the travel direction of the items, driving them along the passage. The passage can be formed by parallel bars (2), joined together by external rings. The jets can be connected by hoses (10) to a plenum chamber, in turn connected to the outlet of a centrifugal fan.

Title: Wavelength measuring instrument for optical lasers - has reflector and rotatable mirror at focal points of elliptical mirror
Inventor: GRASSME WOLFGANG DIPL PHYS
IPC: G01J3/18
Filed: 1977-05-09
Abstract: The optical wavelength measuring instrument esp. for laser radiation, consists of a reflecting screen (4) placed at one focal point of an ellipse (2) onto which a laser beam (8) impinges. The emerging rays pass through an aperture (12) to a concave mirror (5) at the far end of the ellipse. The elliptical surface of the mirror causes the separate paths (13-15) to converge at the second focal point of the ellipse (3). At this point, a plane rotatable mirror (6) can be turned through an angle corresponding to a certain wavelength. The reflected ray is then detected by a photo-electric sensor (7) which can be moved around an arc on the focal line of the ellipse so that maximum signal intensity corresponds to the spectral centroid of the light under investigation. The angle of rotation of the plane mirror can be transformed into an electric signal to drive an analogue or digital display of the wavelength.

Patent DE-2741372-A1 (DE)
Inventor: BIZAJ ERNST
IPC: F16F1/36
Filed: 1977-09-14
Abstract: The device is mainly used for supporting machines and apparatuses. It permits both the shock absorption of large amplitudes in the vertical direction and also the support of a large weight. A carrier (8) for the object which is to be supported is arranged in a base (10) which is constructed as a frame and is provided with a base surface (7). Both the base (10) and the carrier (8) are provided with mutually parallel side walls (15, 16) on whose opposite surfaces (43, 44) rubber strips (17) are mounted, via which the carrier (8) is supported in an elastically flexible manner on the base (10). Each of the rubber strips (17) has two flat cross-sectional sections (21, 22), which are inclined with respect to one another and of which the lower section (21) engages under the carrier (8) while the upper section (22) is at right angles to the base surface (7). As a result of the inclined position of the lower cross-sectional section (21) with respect to the upper section (22), a combined material load, consisting of compression and shear stresses, is produced in the lower section (21) when the carrier (8) is loaded vertically. Movements of the carrier (8) in the horizontal direction caused by vibration movements of the object are absorbed by the upper cross-sectional sections (22). <IMAGE>

Title: Direct current electrical heat treatment of continuous metal band - in protective atmosphere contg. small amounts of reacting gases
Inventor: DOLAN JAMES J
IPC: H05B3/00
Filed: 1978-02-07
Abstract: Electrically heat-treating a continuously travelling band of sheet metal comprises conducting the band in zig-zag fashion over spaced guide rollers with d.c. potentials applied to some of the rollers to generate resistive heating. The length of successive passes from the inlet to the outlet end of the travelling band is reduced to compensate for the increase in the electrical resistivity of the band with the increase in temp. in the course of its travel. This equalises Joule effect in the successive passes. The walls of the housings along successive passes are disposed in close proximity to the faces and edges of the band to maximise the temp. and atmosphere within the housings. Used for the heat treatment of continuous lengths of ferrous metal prior to coating with Al, Zn, Sn. No inductive electric currents are generated in the housing walls as in the case when a.c. potential is applied to the rollers. The lack of any other form of heating other than the d.c. energy results in a low thermal inertia system. This results in fine and rapid control of heating to produce uniform physical and metallurgical properties across the entire width of the band. The reducing gas contains 10% H2 and eliminates the danger of explosions.

Title: Tufting machine - with pile heights varied by individual stepping motors for each pair of pile yarn feed rolls
Inventor: WOODCOCK DOUGLAS GEORGE
IPC: D05C15/32
Filed: 1978-08-08
Abstract: Pile height variations for patterning are effected by providing individual stepping motors for each pair of feed rolls which advance pile yarns to the needle bar of a tufting machine. Pulse trains of variable repetition rate are applied to the motors by an electrical system controled by a pattern control mechanism pref. transparent and opaque areas, and a light sensor controlling a speed selector for each stepping motor. Speed selector controls translator which applies pulse to its motor, and stop run logic renders translator operative under needle bar control. Simplification is achieved by having one feed roll on the stepping motor shaft, and other feed roll geared to the first roll.

Title: Protection cover for loudspeaker - depends on stray field from permanent magnet to hold itself in position
Inventor: KOBER WOLFGANG
IPC: H04R1/02
Filed: 1978-11-15
Abstract: To protect the delicate active parts of a loudspeaker, the practice has been widely adopted to provide robust grids or metal covers with holes. However, in outdoor use especially, these covers still permit foreign matter such as dust etc. to enter the membrane area; also, the cover holes may be filled up with dirt. The difficulty of removing the cover for cleaning or repair purposes tends to lead to unattended equipment with resulting worsening performance. By deliberately increasing the stray magnetic field derived from the loudspeaker permanent magnet (14), it is possible to hold the cover plate (48) in position without requiring any fixing other than the magnetic force exerted on the at least partially ferrous cover component (48) by the loudspeaker frame (38). This permits manual removal without any tools.
