Title: Watertight knapsack esp. for use on boats - has hose-shaped mantle of average human leg length and base size equivalent to that of human foot
Inventor: SEIDL LUDWIG
IPC: A45C9/00
Filed: 1977-11-23
Abstract: The watertight knapsack is designed for alternative use as a watertight boot on boats.

Title: Tufting machine yarn feed - with row of pressure heads to give selective roller dye application to yarns for patterning
Inventor: WOODCOCK DOUGLAS GEORGE
IPC: D05C11/24
Filed: 1977-12-07
Abstract: Tufting machine has a feed mechanism to deliver yarns lengths of different colours to achieve the required patterning effects. A band of parallel yarn lengths, is drawn continuously and horizontally successively through a row of pressure heads, each with a vessel of fluid dyestuff with a rotating lower roller and an upper roller which rotates at the same speed as the yarns passing through. The pressure head rollers are each connected to a magnetic solenoid so that the rollers ca be clamped together while they are drawn through. A control unit gives selective operation of the roller solenoids. A steaming unit is located after the pressure heads to fix the applied dyestuff, the steaming unit outlet leading directly to the inlet of the tufter. System allows the length of yarn treated by dye to be variable, is required, so that the patterning range of the tufting is increased.

Title: Positive joining of thermoplastic shaped elements - involves local heating by focussed radiation beam and deformation by punch
Inventor: LANDES GEORG
IPC: H01H49/00
Filed: 1978-06-23

Title: Permanently increasing conductivity of graphite fibre prod. - by intercalation by electrochemical treatment, gives prod. useful in electric circuits and motors
Inventor: BESENHARD JUERGEN O
IPC: C25D5/00
Filed: 1978-06-30
Abstract: Permanently increasing the conductivity of graphite articles by intercalation is effected by treating fibrous articles and textiles of graphite with liquid electrolyte in an electrochemical cell by transporting them continuously as anode and/or cathode through the electrolyte, which contains dissolved intercalation substances or is intercalated, a direct current being passed between the electrodes. The transport rate in mass/unit time and the transported electric charge rate in coulomb/unit time are mutually adjusted so that a max. increase in conductivity is attained and the graphite fibres are continuously covered with an electrically insulating material immediately after that. The prod. is specified for use as conductor in electric circuits and/or motors or in equipment utilising its ohmic resistance. Intercalation does not reduce the (flexural and tensile) strength or chemical stability of the graphite fibres or lead to marked swelling.

Title: Colour matching procedure for painting metal panels - using magnetic foil painted on one surface with trial colour and attaching to original surface for judging
Inventor: RATH FRANZ-J
IPC: B44D3/00
Filed: 1978-10-18
Abstract: The colour tone comparison method is for correct colour matching when painting metal plates and is esp. useful when repairing damage to motor vehicles so that the finished work does not appear as a patch on the bodywork. A magnetic foil is painted with the colour presumed to match the original and is placed on the region to be treated. Pref. a round opening is provided in the foil and its circumference is laid on the given coloured surface so that false impressions arising from reflections, can be avoided. Time is saved since work does not begin until correct matching has been achieved and subsequent paint removal is not necessary. The foil can be a square with 90 mm side and about 0.5 mm in thickness.

Title: Domestic machine security circuit against damage by water - cuts off water and electricity on detecting floor moisture
Inventor: MUELLER ECKART DR ING
IPC: D06F33/47
Filed: 1979-05-04
Abstract: Below or close to a machine for domestic purposes using water, on the floor, a humidity detector is positioned. This is connected to an electronic or electrical circuit of a conventional type, which, when the floor is wet, closes the magnetic valve in the line connecting the fresh water supply to the inlet of the machine. Safety device comprising detector, leads and circuit is a separate unit, supplied from the mains, which, when there is water on the floor cuts off the supply to the machine. Response of the detector to moisture can be adjusted and if the detector is missing, the supply is switched off. Device prevents completely serious damage by water since, as soon as there is any leak whatever in the system, the feed of the mains water is interrupted.

Title: Extending ladder made entirely of plastics - has flanges on paired plastics sockets for rungs, engaging stringer side recesses
Inventor: SMITH F CHARLES
IPC: E06C7/08
Filed: 1979-07-05
Abstract: Rungs are held between plastics stringers, with no metal components involved, in esp. an extensible type of ladder made of glass-fibre-reinforced plastics. The rounded ends of the rungs (10) each engage two plastics sockets (11-14) in a row. The outer ends of these have polygonal flanges (11'-14'). The sockets firmly engage holes (21,22) passing transversely through the stringers (15,16). Their flanges firmly engage matching recesses along the inner and outer sides of the stringers. The outside faces of the flanges are aligned with these stringer sides. The sockets may be welded or glued to the stringers. This is simple and easily made, with smooth outsides for sliding, while rungs have full tread surfaces, and absence of metal makes it suitable for work involving high tension electricity.

Title: Variable output high intensity light source - uses reflectively coated fluorescent collectors connected to light guides terminating at concentration point
Inventor: PAPE HEINZ DIPL PHYS
IPC: F21V9/16
Filed: 1979-08-23
Abstract: The light source with a high output and which permits a wide variation of the spectral intensity distribution, uses a set of concentric fluorescent bodies (1,2,3) with a reflective coating (4) at one end. These bodies absorb light emitted from a set of light sources (5) between them, at that end, which can be moved inwards and outward. Between the two sets are reflectors (6) which can also be moved inwards and outwards. The whole is incorporated in a reflective housing (7) and connected to light guides (10) at the other end. The light is concentrated at a coupling point (8) of the light guides, which also carry a reflective coating. The various fluorescent bodies are doped with fluorescent material, with a different colour fo each body for each body. A cooling medium can be circulated through the device. The light source can be gas discharge lamps. At the junction between the fluorescent bodies and light guides are parabolic mirrors.
