Title: Auxiliary drive motor for building material mixer drum - operates only when measured main motor output is inadequate
Inventor: BITTMANN PETER
IPC: B01F7/04
Filed: 1989-12-20
Abstract: A mixer drum (2) for building materials and additions such as water has generally equivalent sets of mixer tools (3,4) projecting drum end walls to engage journals (7,8) connected by transmision elements to a pair of electric motors (11,12). One motor (e.g. 1) is the main motor since it operates permanently while the second motor (12) operates as auxiliary drive during starting, after admission of fresh additives etc. The main motor (11) is coupled to a transducer (13) which measures its applied force. Should this drop below a set minimum no longer effective for sole drive of the mixer, a signal generator (14) emits a signal causing the auxiliary motor to share the drive. The shaft driven by the auxiliary motor incorporates a free-wheel unit (16). ADVANTAGE - Avoidance of unnecessary power consumption makes operation cheaper and quieter, with total mixer life prolonged.

Title: Electrode construction for use in gas discharge lamps - with cathode sepd. into front end with electron emission chip, and plated rear part to prevent glass adhesion
Inventor: ONISHI YASUO
IPC: H01J61/073
Filed: 1989-12-21
Abstract: The cathode consists of a front part (8a), a rear part (8b) made of a high m.pt. metal and separated by a ringshaped groove (9), and a connector lead (12). On the front part (8a) a chip has been mounted of a highly electron emissive material (10) at the leading edge. This material is made form a mixture of W-powder and an electron emitting substance, pref. an alkaline earth metal system, and given the right shape. The rear part (8b) is plated with Rh, Re or Nb. The electrode metal is pref.  W or Mo. The electronemitting material is pref. a double or mixed oxide of Ba-aluminate formed from Ba-oxide and Al-oxide. USE/ADVANTAGE - The choice of electorn emitting material allows the discharge to be run at a lower temp. which reduces the recrystallisation, melting and/or evaporation of the electrode metal and the chip. This results in much more stable discharge and a longer operating life. The separation into front and rear parts of the electrode using a groove makes plating and fitting the electrode much easier.

Patent DE-4030580-A1 (DE)
Inventor: MISCHKE PETER DR
IPC: C09B67/00
Filed: 1990-09-27
Abstract: When highly concentrated aqueous solutions of azo dyes are produced by the direct method of diazotation and coupling reactions, considerable difficulties usually arise because viscous phases occur in the course of the diazotation and coupling reactions which cause agitation problems in the reaction equipment used which in turn result in incomplete synthesis. This drawback was overcome with the novel process for making concentrated aqueous solutions of an anionic dye in an aqueous medium in that the diazotation of the aromatic amine used as the diazo component and/or the coupling reaction between the diazonium salt and the coupling component is performed in the presence of an auxiliary which has a viscosity lowering effect on pasty phases. Such auxiliaries may for example be alkyl-substituted naphthaline sulphonic acidformaldehyde condensation products, lignin sulphonates, polyacrylates and copolymers of maleic acid anhydride and methacrylic acid or acrylic acid.
