Title: Electrophotographic registration material - with chlorinated polyvinyl carbazole layer on a selenium-contg. photoconductor layer
Inventor: BAUMANN GUENTER
IPC: G03G5/043
Filed: 1979-09-20
Abstract: Electrophotographic registration material is made by dissolving polyvinylcarbazole (I) in CHCl3 and chlorinating the (I) in soln. until the desired degree of chlorination is achieved. Chlorination is then stopped by adding an inhibitor and the soln. is immediately applied to a preformed Se-contg. photoconductor layer on an electrically conductive carrier. Pref. the (I) is dissolved in CHCl3 at 20-50 deg. C to give a soln. concn. of 1-20 wt.%, esp. 8-12 wt.%. Chlorination is pref. continued to a Cl content of 0.2-20 wt.%, esp. 5-15 wt.%, pref. under an inert gas atmos. such as Ar or N2 and with simultaneous irradiation with light in a range from UV to middle I.R. The inhibitor added to stop chlorination is e.g. o-terphenyl, nitrobenzene or quinone, esp. up to 30 wt.% O-terphenyl and opt. with the addn. of 1-30% of a volatile oxime such as ascinine. Pref. after the resulting soln. has been applied to the photoconductor layer, the CHCl3 is removed by forced drying in the dark. The chlorinated (I) forms a radical sensitised charge transport layer on the material and gives registration materials with high sensitivity, low residual potential and good flexibility. 5 g (I) was dissolved in 45.5 g CHCl3 under N2. At the end of dissolution, the Cl content of the (I) was 7%. The soln. was irradiated with a high press. Hg lamp for 120 mins. to increase the Cl content to 12%, than 1 g o-terphenyl was added as inhibitor. The resulting soln. was suitable for application to photoconductors comprising vapour-deposited Se on an aluminium substrate.

Title: Fan for pressure jet oil burner - has motor axially adjustable to vary fan inlet opening and air flow
Inventor: SCHMITZ GEORG
IPC: F04D29/56
Filed: 1980-01-18
Abstract: The fan has an impeller (2) mounted on the shaft extension (3) of an electric motor (4).

Title: Rolling door drop prevention safety mechanism - has swivelling off-centre cage housing meeting damping element
Inventor: HAAKE WERNER
IPC: E06B9/84
Filed: 1980-05-02
Abstract: A blocking wheel, non-rotatably connected to the horizontal spindle, acts in conjunction via blocking units, with a cage fixed inside a housing on a fixed post, to prevent undesirable unrolling of a large rolling door, or other sheet wound up in an opening. In the bottom area, in the unrolling direction, the housing (6) is borne by the post (1) off-centre, so as to be able to swivel. At the opposite bottom edge it is in contact with a modulating element (10) which becomes effective in the direction of swivel.

Title: Plug connection for printed circuit - has two insulated parts with solder tags which snap together forming closed housing with internal spring connectors
Inventor: KOENNEMANN ALFRED ING GRAD
IPC: H01R13/20
Filed: 1980-05-09
Abstract: The plug connection is made up of two halves, a plastic housing (1) and a plastic cover, both of which contain contact springs (3), similarly shaped. Each contact (3) is made from a sheet metal stamping and bent, so that it has a vertical side (8), a base (5,6) and a 'V' shaped tongue, with the apex of the 'V' extending past the centre line (10) of the two solder tags (11), which protrude below the housing. The arrangement ensures, that when the two halves of the plug connector are placed together, the inclined 'V' shaped parts of the contact (3) slide over one another until they pass, and the upper edges of the walls (20) of the cover stop at the base of the housing. This forms a snap connection, which can easily be separated, and guarantees an excellent contact between the two halves.

Title: Wind energy machine - uses two adjacent piezoelectric slabs and interconnected to generate electrical energy by contraction and expansion forces during vibration
Inventor: WAGNER GUENTER DIPL ING DR
IPC: H02N2/18
Filed: 1980-05-10
Abstract: The machine uses a flowing medium, e.g. air to convert energy directly into electrical energy by the piezoelectric effect via two piezoelectric slabs. These are made of polyvinylfluoride and laid one on the other and are connected together. As the arrangement, so formed, bends, one slab stretches and generates a voltage in one direction, and a slab that contracts and generates a voltage of opposite polarity, such that when the arrangement is exposed to the flowing medium and is made to vibrate, electrical energy can be obtained.

Title: Electric coffee or tea making machine - has power supplied to heating element in riser pipe controlled by initial water temp.
Inventor: SCHOENBERNER SEN HANS-GUENTHER
IPC: A47J31/54
Filed: 1980-06-06
Abstract: The machine has a riser pipe extending between the outlet of a water container (1) and a filter unit (6) and incorporating an electric heating element (4). The water container (1) is filled with hot water and a temp.-dependent resistance (R1) is located at its outlet associated with the control circuit (8) for the heating element (4) so that the pulsed ON-OFF switching of the latter is dependent on the detected water temp. The higher the latter the less the power supplied to the heating element (4). Pref. the water temp. is detected using a negative temp. coefficient resistance. The control circuit (S) for the heating element (4) has a sawtooth generator and a comparator comparing the output of the latter with the characteristic of the temp.-dependent resistance (R1) to control firing pulses for a triac. The system ensures that the heated water is fed to the filter unit at a constant rate independent of the initial water temp.

Title: Internal combustion engine, especially for a motor vehicle
Inventor: DANCKERT HERMANN DR ING
IPC: F02F7/00
Filed: 1981-03-14
Abstract: A crankshaft bearing block (2) comprising a bearing saddle (4) and a bearing cover (5), both of which are composed of a material, especially grey cast iron, the coefficient of thermal expansion of which is as close as possible to that of the crankshaft material, is bolted onto the engine block (1) of the internal combustion engine, composed of light alloy. Machining of the bearing surface (8) is thereby made easier, since in contrast to known designs, the appropriate tool needs to machine only one single material, viz. that of the bearing block (2), and, in operation of the internal combustion engine, disadvantageous effects on the bearing play due to the differing coefficients of thermal expansion of the light alloy of the engine block (1) and the crankshaft are excluded. <IMAGE>
