Title: Shade for light fittings - consists of crossed strips whose crossings are masked by decorative star shaped connectors
Inventor: DEATON CHARLESUTTER
IPC: F21V11/06
Filed: 1974-04-19
Abstract: The shade is used for covering ceiling mounted lighting fittings from direct view. Its special purpose is to form a shade for these lighting fittings of the type known as the egg box type shade consisting of crossed, interwoven strips or plates. This shade is built up from a pattern of modular plates which are fastened on supports providing ready access to lighting fittings. The edgeways crossing transverse and longitudinal ribs of the lighting fitting shade are masked at their crossings, on the lower edges by star shaped connectors. These four armed stars hide blemishes at crossings and contribute to a better appearance of these crossings. The stars have on their upper faces four pairs of ribs which form four channels for gripping the edges of these ribs and these star connectors act also as stiffeners at crossings.

Title: Involute gear teeth with varying form correction - produces teeth with longer arc of contact to reduce shock loading
Inventor: EHRLICH WILLIBALD
IPC: F16H55/08
Filed: 1974-09-27
Abstract: The invention is an extension of the method of correcting the tooth form of a pair of mating gears by increasing the dedendum of one gear with a corresponding reduction in the dedendum of the other gear. With the involute tooth form this can be done by feeding the gear cutter in more deeply in the one gear and less deeply in the other gear. The invention proposes a variable amount of correction across the width of the gear so that the gear wheel (1) has a conical periphery. The mating gear (2) is corrected in the opposite direction. If both wheels are corrected in the same direction, they can be used as bevel gears (2) and (3).

Title: Combined N path and bandpass filter - changes mode by operation of switches by N path filter output processed by timing signal generator
Inventor: LANGECKER KARL
IPC: H03H19/00
Filed: 1975-11-26
Abstract: The filter has n paths whose characteristic is changed by sequential switches within one switching cycle into a bandpass characteristic for the whole filter. The control signals for the switches are derived from the N-path filter (1) output signal through a timing signal generator (6) between the filter output (5) and the control inputs of the switches. If an input signal for the filter is missing makes the rest position of the switches leads to non transforming filter operation. The frequency of the timing signal generator's control signals is equal to that of the highest amplitude signal in the n path filter output.

Title: Cuprous test paper prodn. by impregnation with cupric salt - followed by reduction, allows prodn. in aq. medium
Inventor: HARDT HORST DIETRICH PROF DR
IPC: G01N31/22
Filed: 1976-01-24
Abstract: Prodn. of Cu(I) test paper involves producing the active component, esp. Cu2I2 or Cu(I) pseudohalide, in or on the paper fibre by consecutive chemical treatment. This is achieved by (a) impregnation with a Cu (II) salt then (b) converting this to a Cu (I) cpd and preventing the formation of free I2. In an example paper was impregnated with conc. aq CuSO4 soln. and then with a soln. of KI and ascorbic acid in water so that Cu2I2 was deposited on the fibres. The test paper forms fluorescent cpds. with free organic N bases and NH3, the fluorescent colour often changing on changing the temp. e.g. cooling in liquid N2. It can be used in qualitative spot analysis and also in electrophoresis and paper and thin layer chromatography. Impregnation is carried out entirely in an aq. system avoiding the use of organic solvents, e.g. MeCN used in the parent patent, and a much higher Cu2I2 concn. can be obtd. than is the case when MeCN is used. The process is simple, safe and cheap.

Title: Tube production by helical winding of corrugated strip - has tube transported longitudinally and bent into coils overlapping in width
Inventor: SIEGWART EMIL
IPC: B21C37/12
Filed: 1976-01-27
Abstract: The tubes are produced by helical winding of a corrugated sheet strip. The strip is transported in the longitudinal direction, and is bent to strip coils which overlap partly in width. Each coil up termination of its winding during support on the still-uncoiled strip is exposed in part of its width to a drive force. This drive force is different from the drive force acting on the uncoiled strip at the beginning of bending. The coiling device which performs this process has free rotating guiding support rollers as well as connecting rollers which connect adjacent coils. The connecting roller (5), on the side of the forming coil (10), is part of its axial length, rotates at a peripheral speed different from the opposite connecting roller (6).
