Title: Neutralisation process for treatment of waste water - produced in bottle-cleaning machine using carbon dioxide
Inventor: MNILK REINHOLD
IPC: B01F15/02
Filed: 1973-11-13
Abstract: Neutralisation process is intended for the treatment of water used in a plant for cleaning recipients, such as bottles, for re-use. Detergent is entrained from the different spraying operations. A neutraliser is therefore included in the machine to keep the pH to the reqd. level by the addition of an excess of CO2. The cleaning machine has several treatment posts and the water which is no longer usable passes to a neutraliser where it receives an addn. of CO2. The water is compressed into a tube which acts as a mixing zone for the CO2 which comes from the inlet through a compressor; some of the water is diverted to a detergent measuring vessel which is connected to a pH meter. When the pH exceeds e.g. 8.9 valves are operated and pure CO2 is admitted to the neutraliser. The process is partic. economical and assures a perfect treatment of the cleaning liqs. and of the effluent before the build-up of any excess of the neutralising agent.

Title: Crank connecting rod split bearing - has bush half with greater radius set on the side with greater loading
Inventor: ROEMER ERICH DR RER NAT
IPC: F16C27/02
Filed: 1973-11-30
Abstract: The assembled conrod with cover has a base bore for the two halves of the bearing. Instead of the normal bore for the bearing surface, the two bush halves exhibit different thicknesses since the half-bush in the conrod end features a clearance of 0.02 mm for the crank pin. This makes the half-bush thicker than the bearing whose inside radius exceeds the radius of bush 1 by 0.04 mm. As a result, the big end of the conrod will be subject to a lesser deformation during the compressive loading. The arrangement is preferably used for the crank of a reciprocating piston motor or compressor.

Title: Brine concn. detector for water softeners - pressure pad in base of brine vessel used to detect gravity fall
Inventor: GEYER HERMANN DIPL ING
IPC: B01J49/75
Filed: 1974-01-25
Abstract: The concn. of brine for regenerating water softeners of ion exchange type is detected by using a pressure pad at the base of the brine vessel. The pad produces an electrical signal when the specific gravity of the soln. above it drops below a predetermined level. The pad consists of a flexible membrane attached to a rigid disc which is supported on a spring and which opens or closes contacts. The pressure disc is supported after a predetermined stroke on a rigid support. If the gravity of the soln falls, the spring lifts the disc and membrane, eventually opening contacts due to the reduction in the static pressure head on the membrane. Esp. for use with water softners associated with washing machines and similar devices. Provides a simple but precise determination of when the brine is spent and can be coupled to a light or similar device to indicate when more salt is required. The membrane protects the device from corrosive attack and it is much cheaper than methods involving measurement of the brine conductivity. It is also more reliable than switches relying on a mechanical action outside the vessel.

Title: Appts. for imitating crazy paving - tools impressed into wet concrete provide pattern representing joints between slabs
Inventor: BOWMAN BRADSHAW
IPC: E04F21/24
Filed: 1974-04-13
Abstract: A method of treating the surface of recently laid concrete paving so as to reproduce crazy paving, uses a tool with three arms extending from it, each arm having a pointed underside so that when forced into the concrete a set of three radial grooves is formed, representing the junction of three irregular slabs. A set of such markings may be made and interconnected by grooves to form a required pattern. To achieve this, the tools may be used in pairs, passing through slotted holes in a support plate which rests on the concrete so that a workman can use a set of such plates and tools, standing on the plates to support his weight. The slots enable the tols to be spaced different distances apart.
