Title: Floor mop with replaceable cleaning head - has telescopic transverse support arms for head displaced by rotating handle
IPC: A47L13/253
Filed: 1977-02-03
Abstract: The floor mop has a detachable cleaning head with pockets each end to fit over the ends of the transverse support. This, which is fixed to the handle (19) has two telescopic parts, (2, 3) which can be displaced relative to each other by rotating the handle (19). These two parts (2, 3) can be locked in their position of use by a locking member (14) coupled by a joint (21, 23) to one of the transverse support members (3). Most of the stresses which occur during use are taken up by the guide members (7, 10) for the arms (5, 6, 11, 12) of the U-shaped support parts (2, 3). The mop head can be easily replaced by rotating the handle which moves the parts of the transverse support towards each other.

Title: Automatic phase control circuit - has switching stage and filter which compares mean phase differences with limits and controls oscillator
Inventor: LUEDER RAINER DR ING
IPC: H03L7/107
Filed: 1977-08-03
Abstract: A circuit provides automatic adjustment of control time constants. A phase detector generates first signal representing a control deviation allocated to the phase difference between input and output signals generated in an oscillator. A filter determines the phase control time constants. The first signal is applied to the filter which delivers to the oscillator second signals representing the control variable. The circuit has a switching stage (SS) to which the first signals (RE) are applied, and which determines the mean phase differences during a specified period and compares them with at least one limit. It delivers control signals (ST) to the filter (FA), by which greater or smaller control time constants are set when the mean phase differences do not reach or exceed the limits.

Title: Cpds. contg. pig brain hydrolysate and adenosine phosphate derivs. - medicaments for intramuscular treatment of arteriosclerosis, lupus parkinsonism and psoriasis
IPC: A61K38/01
Filed: 1978-03-17
Abstract: New intramuscular medicaments consist of (a) 108 mg. pig brain hydrolysate, (b) 7.5 mg. adenosine phosphate, (c) 7.5 mg. adenosin-phosphoric acid, (d) 7.5 mg. adenosine triphosphoric acid, and (e) 60 mg. rutin. Used to treat arteriosclerosis, lupus erythematodes, parkinsonism and psoriasis. The pig brain hydrolysate is protein-free, i.e. hydrolysis is to the free amino acid level. The therapeutic effect of the prepn. is attributed to supply of substances absent from the body of the patient, thus compensating for genetically-induced metabolic disorders. The adenosine phosphate components of the new medicaments are sufficient to stimulate adenylate cyclase activity. The pig brain hydrolysate provided the amino acid building blocks for the formation of enzymes.

Title: Glutaraldehyde sterilisation of fermentation media - with greatly reduced energy use compared with steam sterilisation
Inventor: CREAMER CHARLES EDWARD
IPC: C12P19/06
Filed: 1978-04-27
Abstract: Sterilisation of microbiological media for fermentation by: (a) treating the medium with glutaraldehyde; (b) adjusting the pH of the sterilized medium from (a) to >6.5; and (c) treating the medium from (b) with >=1 nitrogenous cpds. e.g. ammonia, prim. amines, sec. amines, heterocyclic amines, ureas and amides to inactivate the glutaraldehyde. Large savings in energy are achieved c.f. conventional steam-sterilising process, and equipment is less costly. There is a lower loss in nutrients than in steam sterilising. A typical medium for benzylpenicillin fermentation was sterilized with glutaraldehyde (0.1%) at 24 degrees C and pH 5.5, NaOH was added to pH 7 and formed NH3 from (NH4) in the medium which neutralised the glutaraldehyde.
