Title: (2)-Phosphonio and (2)-arsonio ethoxy-carbonyl cpds. - for introducing protecting groups into amino and hydroxy cpds. e.g. amino acids or peptides
Inventor: KUNZ HORST DIPL CHEM DR
IPC: C07F9/72
Filed: 1975-09-06
Abstract: New acyloxyethyl-phosphonium and -arsonium salts are cpds. of the formula: R1R2R3Y+-CH2-CH2-O-CO-X X- (I). In this formula, Y is P or As. R1, R2 and R3 are aryl or alkyl. Z is an anion. X is a group displaceable by a hydroxyl or amino function (pref. Cl) or is the acylated hydroxyl or amino function of an organic substance. The gp. -CO-O-CH2CH2Y+R1R2R3 Z- acts as a protecting gp. for hydroxy and amino functions. (I; X = group displaceable by OH or amino function) are thus useful as agents for introducing this protecting group, while the remaining cpds. (I) are the protected organic amino or hydroxy cpds. The protecting group is particularly suitable for amino acids, peptides, and their derivs. The protecting groups can readily be removed under basic conditions. Examples describe prepn. of (I; Y = P, R1 = R2 = R3 = Ph, X = Z = Cl) and the reaction of this cpd. with L-leucine methyl ester and phenylalanine to give the corresp. N-protected amino acid derivs.

Title: FM digital transmission of analogue measurement signals - allows many different transmitters and receivers to be attached to same transmission line
Inventor: FROEHLICH RANDOLF ING GRAD
IPC: G08C15/04
Filed: 1975-11-06
Abstract: A method of transmitting and receiving essentially analogue measurement signals in a digital pulse coded modulated form, in which many different transmitters and receivers can use the same transmission line simultaneously, is presented. The method is more efficient than similar existing methods but maintains high accuracy. Each transmitting unit consists of an amplifier (1), an A/D converter (2), logic network (3), carrier frequency signal generator (5), modulator (4) and transformer (6). A frequency divider (5a) is used in a feedback arrangement of these units to present a pulse code modulated signal representing the input analogue signal to the isolating transformer (6), which feeds it to the transmission line. Each transmitting unit supplies its own characteristic carrier frequency. The receiving units each consist of a band post filter suited to one particular carrier frequency, a demodulator a digital storage unit and a display.

Title: Coke oven door cleaning unit - providing a system of movable cleaning tools on a chassis suspended from a carriage on e.g. the coke pusher rails
Inventor: NEUMANN HANS
IPC: C10B43/02
Filed: 1975-11-27
Abstract: In the cleaning of the door of a coke oven chamber or of its frame, by bringing up to this a chassis equipped with cleaning tools and mounted on the coke pusher machine or a coke cake guide carriage and after co-ordinating the relative positions of this chassis and the oven door or its frame, by treating the surfaces to be cleaned, the improvement comprises that: (a) the approach movement between the chassis and the door or frame is carried out by >=1 drive unit acting on the door or its frame and on the chasis; (b) the chassis is brought up independently with respect to the door or its frame, with all the degrees of freedom of one direction of displacement in the course of a first phase of the approach movement; (c) centering and abutment (thrust) elements are effective between the door or its frame and the chassis during a second phase of the approach movement; (d) the chassis is fixed to the door or its frame at the end of the approach movement by means of these centering and abutment elements, as well as the drive unit. The process ensures without any uncertainty that the chassis equipped with the cleaning tools, can-independently of each position of the door - be brought up to the door by correct co-ordination of the position and can keep this position unaltered during cleaning.

Title: Continuous compositing of organic waste and/or sludge - and passing the exhaust gas to a sedimentation tank to aid and accelerate clarification
Inventor: KNEER FRANZ XAVER
IPC: C05F17/00
Filed: 1975-12-23
Abstract: The Parent Patent describes continuous composting of organic waste and/or sludge which is passed downwards through a closed aerator. Air, as fine bubbles, is passed uniformly and counter-currently upwards in an amt. determined by comparing pre-set and actual CO2 or O2 content of the exhaust air using separate suction and pressure fans. The air quantity is also regulated by comparing humidity levels in, pref., the upper and lower thirds of the reactor with pre-set values and then opt. adding a water spray to the air entering at the base of the aerator which is pref. heated to 40 degrees C. In this addn. the exhaust from the aerator is passed, as fine bubbles, into the activated zone of a sedimentation tank. The exhausted air, previously unused, simultaneously aerates and heated the sedimentation tank. As ic contains spores and fungi from the composting stage, clarification of the water is improved and accelerated (due to the heat supplied).

Title: Reactor for polymerising and treating cpd. for dental prostheses - is heatable, multi-chamber, container with narrowly spaced cuvettes
Inventor: SCHMIDT ALBERT
IPC: A61C13/14
Filed: 1976-08-21
Abstract: Device for treating polymerisable plastics which are charged to a mould that fits into a cuvette, is a multi-chamber receptacle, the chambers being adapted to receive cuvettes so hat there is as little space as possible between cuvettes and chambers. The chambers are heatable and in contact with a heating medium so as to facilitate formation of an atmos of satd. steam in the spaces during polymerisation. Used for mfr. of dental prostheses, esp. from acrylic cpds. The device operates without application of pressure. Polymerisation time is usually 30 mins., with the prods. being perfectly homogeneous. The polymerisation rate achieved approximates to the theoretical optimum. Owing to the absence of super-pressure during polymerisation there is no risk of the water present in the plaster mould being driven into the resulting plastics matrix.
