Title: Improved efficiency incandescent lamp - has selective reflecting coating inside bulb to divert wasted rays
Inventor: PACE HENRI
IPC: H01K1/32
Filed: 1975-07-02
Abstract: An electric light bulb has its dome coated with a reflective material so that a beam of light is reflected backwards past the bulb socket. By reducing a certain amount of the reflected light which is directed onto the internal surface of the plug connection, the lamp efficiency is improved. The outer envelope (5) slightly pointed (6) so that any light produced by the filament (4) which lands on the inside of the connection (2) is reflected twice in a narrow beam. This contrasts with the broader beam and single reffection of the traditional bulb. Bulbs of 40W and upwards, supplied by 228V can be designed in this improved manner.

Title: Display lamp switching circuit for signalling console - with light monitring switch for selecting required display lamp
Inventor: WEISSHARDT GERHARD
IPC: G08B7/06
Filed: 1975-07-26
Abstract: The display lamp switching circuit is used to select a daytime or night display for a signalling consol, with a light monitoring switch (DS) for the ambient lighting conditions. An alarm clock (LW) is operated via two parallel current paths. One current path has a working contact (d1) connected in series with a relay (D), controlled by the light monitoring switch (DS), and a stationary contact (tn3) of the relay (TN) for switching between night and day operation. The other current path has a stationary contact (d2) of the first relay (D), connected in series with a working contact (tn4) of the second relay (TN). The relays (D, TN) cause a daytime display lamp (TL), or a nigh display lamp (NL) and a continuous source (UW1) or a pulse source (UW2) to be brought into operation.
Patent DE-2534601-A1 (DE)
Title: Camptothecin analogues prepn. - involving alkylation prior to reduction and lactonization of chloro-camptothecin precursors
Inventor: KROHN KARSTEN DR
IPC: C07D471/14
Filed: 1975-08-02
Abstract: A cpd. of formula (I) (where R2 is H2 R is an alkyl residue other than t-butyl or methyl) is alkylated to give a cpd. (I) (where R2 is opt. unsatd. 1-5C alkyl. Opt. (II) is reduced to a cpd. of partial formula (III), and opt. (III) is further converted into the lactone of partal formula (IV) with the aid of trifluroacetic acid. Cpds. (IV) are 20-deoxy-7-chlorocamptothecin analogues. Camptothecin and camptothecin-like cpds. have interesting effects on RNA synthesis. Alkylating at the stage of the camptothecin synthesis corresponding to the cpd. (I) rather than carrying out the alkylation on lactonized cpds. avoids side-reaction and improves yields. In an example (I;R=iPr) is used to prepare (II;R=i-Pr, R2=Et) in 75% yield.
Patent DE-2534632-A1 (DE)
Title: Electronic control circuit for hydraulic drive - includes FETs with capacitor and resistors producing rising control voltage
Inventor: FEHN NORBERT
IPC: B66C13/20
Filed: 1975-08-02
Abstract: The electronic circuit controls the device (9) which in turn controls the angle of operation of the swash plate of the pump which supplies fluid to the hydraulic motoros of the crane. When the current is switched on the transistor (T4) becomes conducting, allowing current to flow to the device (9). A signal in the line (13) makes the transistor (T1) conduct but blocks the transistor (T2). The capacitor (C1) is charged and the rate of charge controls the rate of voltage increase at the gate of the FET (T3) which is preferably a metallic oxide silicon. When this voltage exceeds the threshold voltage of the FET (T3) the resistance of the FET (T3) is reduced causing an increase in current to the deive (9) which increases the angle of the swash plate on the pump.

The rotating cable end is illuminated by at least one light source (13) with a receiving device (14) nearby and the rotation of the disc is abruptly stopped when the light has reached a certain response value. A pair of light sources and a pair of receivers can be positioned at the end of the cable.

Filed: 1975-10-06
Abstract: The Multi-part form set comprises several block-like individual sheets which are positioned over one another and exhibit transfer copying properties and at least a bound edge which holds the individual sheets together via a perforated connection. For the purposes of mechanical printing the set has its bound edge attached to an endless band. After the form set has been written on, the endless web (1) is folded or detached along the perforations in such a way that it forms an envelope with a cover sheet and a backing sheet. The endless band is multi-layered so that after the folding process extra sheets can be added between the cover and backing sheets.

Title: Leather dressing machine carrier beam roller guide - with sets of rollers contacting girder flanges in perpendicular planes
IPC: C14B17/06
Filed: 1975-12-15
Abstract: The roller guide steadies the hide on the work table of the carrier beam as it is carried across a dressing roll. The rollers are arranged in pairs in a roller block and guide the beam in two planes at right angles to each other. In an example, two upright channels are mounted on a foundation plate. The I-beam which carries the work table on top can be raised and lowered by a hydraulic power cylinder. It is reliably guided by two pairs of roller blocks with a certain difference in height between them. Each block includes two rollers which guide the beam on the outsides of the flanges, and two rollers which guide it in a plane at right angles to the first along the insides of the flanges. This provides a secure and reliable guide of simple design for these purposes.

Title: Profiled cam groove controller - for use with triangular needle-lifting cams of flatbed knitting machine
Inventor: GASSINO TERESIO
IPC: D04B15/36
Filed: 1976-05-19
Abstract: In a mechanism for controlling the triangular needle-lifting cams of a flat bed knitting machine, having a holding plate on which a series of such triangular cams is mounted, each of which can move in a direction perpendicular to the plane of motion of the knitting machine needles a series of discs is provided each associated with a needle-lifting cam and fixed to a control shaft which can rotate through a discrete angle round its own axis. A roller runs in a cam-shaped groove machined on >=1 face of each disc and is mounted rotatably on an attachment rigidly fixed to a corresponding needle-lifting cam, in such a way that the displacement of each of the needle-lifting cams is brought about by the rotation of the control shaft which is pref. driven by an inching motor. Provides a control mechanism which can be readily used on flat bed knitting machines with variable carriage stroke, requires no stroke end stops, and is highly adaptable so that a large number of useful knitting positions can be obtd. without exchanging machine components. The equipment is easily fabricated and simple to instal, partic. where a large number of triangular cams is involved.

IPC: B65H19/22
Filed: 1976-06-15
Abstract: The wider for length of material has dish-shaped jaws (10, 11) with semi-cylindrical recesses (12, 13) positioned behind a material cutting station (5), in a guide (14) with material inlet (6) and mandrel outlet (18). The jaws are moved between open and closed position by hydraulic, pneumatic or mechanical auxiliary units (15). In closed position, rotating winding - on mandrels (8, 9) with free-wheel mechanisms project into the space (7) formed by the recesses. The mandrels with attached material are moved at material speed after the opening of the jaws through the outlet to the winding station (17). The material roll is retained by guide rollers (19), and the w winding of the material length (1) is continued by the rollers and continuous belt (20). The mandrels return to their original position in the winding-on station, but the jaws only return, when the material is cut in the cutting station, and the material end has left the outlet. When the end has reached the winding station, the guide rollers swivel upwards, the completed roll is ejected via the belt (20), while the winding station returns to its original position.
