Patent DE-2847038-A1 (DE)
Title: Flap valve with leakage protection - has drain holes connected to leakage space between two flap discs
IPC: F16K1/16
Filed: 1978-10-28
Abstract: A butterfly valve for use in the food and drink industry consists of two circular flaps in series which can be turned through 90 degrees in synchronism by a common drive. They enclose in the 'shut' position a space between themselves from which any leakage fluid is drained off. This has been achieved by a U-shaped passage in both flap valves, with the upper legs pointing to the leakage space and the lower legs registering with a common channel leading to a drainage hose. Any cleansing fluid or steam is thus kept safely away from fluid such as milk, without risk of contamination.

Title: Cylindrical grinder axially positioning device - has work held between centres by measuring deviation and using deviation signal for adjustment of workpiece table
Inventor: KEEFER HERMANN DIPL ING
IPC: B24B49/02
Filed: 1978-12-09
Abstract: The arrangement axially positions a workpiece (6) prior to grinding (7, 17) between centres (4, 5). The workpiece support table (1) carries a measuring instrument (14) which determines the deviation (A) of the actual position from the required position of a radial face (8) of the work. The deviation signal is used to control (3) the setting of the table (1) until the work is correctly positioned. The table may be first moved by a fixed amount (F) away from the tool (7) and then returned by an amount (V) which is the difference between the amounts (F, A). The tool feed (17) may be started during the return movement.

Title: Di:propyl:acetic acid prodn. for pharmaceuticals etc. - by thermal decarboxylation of di:propyl-malonic acid in suspension in toluene
Inventor: REISINGER KURT DR
IPC: C07C51/38
Filed: 1978-12-15
Abstract: In the prodn. of dipropylacetic acid (I), solid dipropylmalonic acid (II) is suspended in toluene and the suspension is freed by distillation under a reflux condenser from the toluene and from any water still adhering to (II), the temp. being slowly raised after the beginning of the evelution of CO2 and heating being continued until the evolution of gas is completed. (I) is valuable prod. for the pharmaceutical industry. Prepn. of (I) by decarboxylation of molten (II) is known, but this method is unsuitable for large scale use because of e.g. stirring problems. The new process avoids such problems, and gives (I) in almost quantitative yield and in a purity of >99%.

Title: Flame monitor for heating systems etc. - uses triac switch with differing switching delays obviating electromagnetic relay
Inventor: SCHWARZ SIEGFRIED
IPC: F23N5/20
Filed: 1979-02-20
Abstract: The flame monitor has a change-over switch for testing and normal operation. The flame alerting switch (1) switches two parallel aggregates in and out with different delay times. Such aggregates might be the ignition unit (3) and the thermal time switch. The flame alerting switch consists of a triac switching a.c. but controlled by d.c. The triac's turn-on current is different for the positive and negative halfwaves. The delay time is produced by an RC circuit connected to the triac's gate and gives different delay times depending on the polarity of the half-wave. The monitor detects 'flame', 'no flame' and 'external light'.

Title: Warning lamp with improved visibility - has fixed or rotating beam directed upwards instead of sideways within zone around axis
Inventor: ELLINGHAUSEN HERMANN
IPC: B60Q1/26
Filed: 1979-05-19
Abstract: The rotary beam signal lamp mounted on a maintenance vehicle, particularly a vehicle used for road repairs etc., has its beam directed upwardly instead of horizontally as in the more conventional manner.

Title: One-way road incorrect entry barrier - is sectioned assembled tilting plate depressed only from correct side
Inventor: GLAHN HANNS ING GRAD
IPC: E01F13/10
Filed: 1979-07-25
Abstract: The system provides visual and mechanical checks to entry into a one-way street or motorway lane in the wrong direction. A tilting sleeper, made up from individual elements, is easily pressed down under the road by vehicles travelling in the correct direction, which drive over it without damage; it then automatically rises to its original position. Vehicles approaching the other way cannot pass over it without damage, esp. to the tyres. The tilting elements (7) pref. have reflectors (8) fitted to their head pieces so as to be visible only from the wrong approach direction. Elements can be laid on a saddle piece (3) so as not to jam even when crossed at an angle. This effectively prevents incorrect entry.

Title: Enhanced NMR detection appts. for explosives - has transmitter and receiver connected to RF coil surrounding sample holder near magnet
Inventor: KING JAMES DERWIN
IPC: G01R33/44
Filed: 1979-08-29
Abstract: The apparatus comprises a magnet to produce a magnetic field acting on the comingled first and second atomic elements of the samples which magnetic field has a intensity. A RF coil acts at right angles to the magnetic field acting on the sample. A transmitter is connected to the RF coil to produce a transmitted pulse burst of specified frequency, amplitude and duration acting on the sample. A receiver connected to the RF coil forms an output voltage proportional to the nuclear magnetic resonance response of the nuclei of the first element. A device is for controlling the magnetic field intensity of the magnet to achieve a level selected such that the resonant frequency of the first element in the nuclear magnetic resonance mode is approximately equal to the second element nuclear quadrupole resonance so that the NMR signal at the receiver is enhanced.

Title: Air conditioning conduit system accessory - adjusts ratio between circulating and discharged air in accordance with blower output
IPC: F24F13/12
Filed: 1980-10-20
Abstract: The accessory is for a conduit system circulating and discharging air, the ratio between discharged and circulating air being adjustable, typically dependent on the output from a blower. The ratio can be controlled by parameters of the air in the room served, e.g. smell, temp. humidity etc., and control can be by a flap (8) or deflector set so as to vary the cross-sections of the passages for circulating and discharged air in inverse proportion. It is mounted in a T-piece in the conduit with separate outlets for circulating and discharge air.

Title: Preliminary removal of deposited harmful gases from regenerator - in purificn. and heat recovery from combustion fumes
Inventor: FUNK HARALD F
IPC: B01D53/00
Filed: 1980-12-08
Abstract: Fumes derived from combustion processes and contg. harmful gases have the dust removed in a standard unit, are cooled to an intermediate temp. and then taken over a heat exchanger in the form of a regenerator producing temps. low enough to condense the harmful gases. The remaining portion of the fumes is further cooled by expansion and then taken in reverse flow over the exchanger to cool the exchanger and be returned to the intermediate temp. During a first short stage (e.g. 3-20 secs.) of the reverse flow the deposited gas are regasified and taken with the fumes for further purificn. During the longer remainder (5-10 mins.) of this stage the rest of the charge is taken for utilisation of its heat content, e.g. for preheating combustion air or feedwater. For furnaces, cement kilns, etc. The regenerator surface is cleaned simply by controlling fume flow direction, with no additional appts. and hence with two regenerators in the sepn. stage it is possible to operate continuously.
