Patent DE-3633682-A1 (DE)
Title: Heating block for heating valve blocks and measuring instruments
Inventor: HESS JOACHIM DR ING
IPC: F16K49/00
Filed: 1986-10-03
Abstract: The invention relates to a heating block for heating valve blocks and measuring instruments. The heating block (1) consists of a block-shaped elongated heating element (2) with at least one flat longitudinal surface as contact surface (4, 10) for heat transfer contact to a countersurface (5), for example a valve block (6). In the heating element (2) a longitudinal hole (12) is provided in the immediate vicinity of the contact surface (4, 10) so that only a thin crosspiece of material (13, 14) remains between the hole (12) and the contact surface (4, 10). An elongated heating element (15) is inserted in the hole (12). In an opening (17), which extends to the hole (12), at least one miniature thermostat (20, 21) or temperature sensor is placed. Because of the block-shaped formation of the heating element (2) and the position of the heating element (15) as well as the thermostats (20, 21) a good regulation behaviour for the purpose of the application is achieved with a compact, space-saving shape. By attaching heater fins (3), which in an additional embodiment can be built as separate attachable fin elements, the heating block (1) can also be equipped for exclusive or additional convection heating. <IMAGE>
Patent DE-3643994-A1 (DE)
Title: Voltage multiplier circuit
Inventor: ISHIKAWA MASAHIRO
IPC: H01L29/788
Filed: 1986-12-22
Abstract: In order to facilitate the construction of a semiconductor circuit containing a voltage multiplier circuit, the last-mentioned circuit is so designed that one of the components, which forms a part of each capacitor in a plurality of parallel-connected capacitors, also forms part of each diode in a plurality of series-connected diodes which are associated with the capacitors. The layout of the components facilitates a reduction in the number of the components and the steps needed to fabricate the ICs as a whole and prevents the formation of stray capacitance and reverse voltages which reduce the multiplier efficiency, as a result of which the number of capacitors and the surface area needed for them on the chip are reduced.
Patent DE-3644978-A1 (DE)
Title: Cap for writing instruments and applicators
Inventor: PFEFFER MICHAEL
IPC: B43K23/12
Filed: 1986-11-27
Abstract: In order to be able to remove the instrument tip in a writing instrument and applicator, the cap has a hexagonal recess which, after removal of the cap, can be fitted onto a hexagon of the tip of the instrument. This entails the risk of contamination. The cap is to be so designed that, in the assembly operation, the cap covers the tip of the instrument without being refitted. The tip (2) of the instrument and the cap (3) each have teeth (8, 18). In the normal position of the cap (3), a latching upward projection (5) of the cap (3) engages into a latching recess (6) on the tip (2) of the instrument and the teeth (8, 18) are at a distance from each other. If the cap (3) is pushed further onto the tip (2) of the instrument, the teeth (8, 18) come into engagement with each other, so that the tip (2) of the instrument can now be unscrewed from the shaft (1). The cap is particularly suitable for writing instruments and applicators which have exchangeable ink cartridges. <IMAGE>

IPC: H02G3/08
Filed: 1987-03-28
Abstract: An explosion-proof and/or firedamp-proof insertion lead-through has a sleeve body (10), guide elements (13, 14 and 18) for a plurality of electrical cable strands (19, 20), which have a stripped region (21, 22) within the region of the sleeve body extent, and a casting resin lining, which is inside the sleeve body (10) and covers the stripped regions (21, 22) of the cable strands (19, 20). Provided inside the sleeve body (10) is a drum-like basic body (14), which has at both its ends axially running grooves (18) which are distributed uniformly around the circumference, are in each case in line with one another and into which the cable strands (19) can be fitted with their insulation in a clipping-in manner. At one end of the sleeve body (10) there are likewise axially running inner grooves (13), which correspond to the number of grooves (18) and taper conically towards the free end of the sleeve body (10). Consequently, the cable strands (19, 20) are securely clamped. The lead-through is for use in explosion-proof and/or firedamp-proof equipment. <IMAGE>

Title: Method and circuit arrangement for cancelling induced noise voltages
Inventor: FORM ERNST
IPC: H04B3/11
Filed: 1987-04-25
Abstract: To cancel induced noise voltages in telecommunications cables, a cancellation voltage is formed from the noise voltage by means of an amplifier (V) and is induced via a reduction transformer (RT) into the telecommunications wires. A residual voltage is used in normal operation to re-adjust this amplifier (V). If the amplifier (V) is overloaded, it is switched over to re-adjustment dependent on the voltage drop on a series resistor (R1) between the pilot wire (P) and one amplifier input (E1). This switchover is initiated by means of a voltage sensor (SS) to which a measuring sensor (Z1) which records the current (J) in a secondary path of the pilot wire (P) is assigned. <IMAGE>

Filed: 1987-12-09
Abstract: In a method and apparatus for separating solid granular material of different densities, e.g. a mixture of coal and run of the mine dirt, material to be separated together with a control medium is fed through an inlet 4 to a first vessel 1 where it is divided by a vortex created by dense medium fed through an inlet 6 into relatively heavy and light fractions and discharged through separate axial and tangential outlets 7, 8. The heavier fraction discharged through the outlet 8 is fed directly to the inlet 14 of a second vessel 2, such as a cyclone separator, and further separated into two fractions of different densities. Supplementary dense medium may be added to the vessel 2 through an inlet 16 or 17. <IMAGE>

Title: Process for the preparation of saturated, odd-numbered carboxylic acids by oxidative degradation of saturated even-numbered fatty alcohols with nitric acid
Inventor: CLAUS HARALD DR
IPC: C07C51/27
Filed: 1988-01-14
Abstract: In the oxidation of saturated fatty alcohols with nitric acid, according to the prior art the carboxylic acid having the same number of C atoms is obtained as the main product and the carboxylic acid which is shorter by one C atom only in a small amount. At higher temperatures of 65 to 100@C, the carboxylic acids which are shorter by one C atom are obtained with concentrated aqueous nitric acid in an amount of at least 15 mole per mole of alcohol in high selectivity. By the addition of paraffin before the distillation, the yield can be increased and the formation of strongly exothermically reacting distillation residues can be prevented.

Patent DE-3802494-A1 (DE)
Title: Firework rocket
Inventor: GARMS GUENTHER
IPC: F42B4/14
Filed: 1988-01-28
Abstract: Firework rockets are used for visual and audible entertainment. In consequence, there are ongoing efforts to construct them in such a manner that they provide effects with a large number of changes. Previous firework rockets could do this only to a limited extent, since they normally rise vertically and then produce a visual and audible effect. The invention is now based on creating a firework rocket which makes it possible to produce an effect which differs from the normal. In the case of a firework rocket according to the invention, an effect which is different from the normal is created by providing a plurality of rocket sections (14, 15), of which the upper rocket section (15) has a functional charge (31) which makes possible a movement trajectory differing from the normal. This movement trajectory is expediently indicated to the observer by continuous illumination (illuminated tail, trail of light). The invention is particularly suitable for firework rockets as well as for signalling rockets or flares. <IMAGE>
