Title: Structural element for custom built unit furniture - has profile altered to improve aesthetic appearance and for hiding of fasteners
Inventor: RENSCH EBERHARD GOTTHARD
IPC: F16B12/44
Filed: 1974-09-20
Abstract: The structural element is made with a standard profile formed by a flat elongated base (2) of rectangular cross section. Perpendicular to this is a central web (4) with its top terminating in another flat section (9), similar to the base, but smaller and parallel to it. Midway between these two is another similar section (3), forming a pair of flat bottomed grooves (5) each side of the central web. Below the flat base are two L shaped sections (7), each near the end with their free ends (17) pointing inwards. Each profile (1) forms one side of a square or triangular element, with its faces angled (8) at 45 deg. or 60 deg. respectively.

Title: Thermoplastic pre-form moulding - for subsequent blow moulding of hollow articles
Inventor: STAEHLE HERMANN DIPL ING
IPC: B29C49/02
Filed: 1975-01-31
Abstract: In the production of thermoplastic pre-forms for blow moulding hollow articles, e.g. bottles, by filling the hollow mould corresponding to the outer profile of the preform with thermoplastic resin and pressing it round a mould core, which can also be used as the blow mandrel, coaxially projecting into the mould cavity, (a) the mould core is initially moved, at least partly, out of the mould cavity into the free part of which the thermoplastic resin is then injected and (b) the mould core is then pressed back againt into the mould cavity, further thermoplastic resin being injected during or directly after this step. Avoids the difficulties which can arise both in the injection moulding of the pre-form e.g. premature cooling of the thermoplastic resin leading to non-uniform wall thickness, and in the press moulding e.g. the introduction of either too little or too much resin into the pre-form mould cavity.

Inventor: BECK LEE
IPC: A23L33/19
Filed: 1975-05-23
Abstract: Agent with anti-caries activity contains cows' milk immunoglobulin. The agent is produced by immunising cows with Streptococcus mutans and isolating the agent from the cows. The agent is a milk prod. contg. antibodies against the cariogenic bacterium Streptococcus mutans and can be applied to the teeth to inhibit dental caries. The fact that the antibodies are contained in a completely natural foodstuff makes the agent partic. easy to administer. The dried milk prod. can be diluted with water to form a mouthwash, or may be incorporated into sugar-free sweets (e.g. chewing gum, bonbons or ice-creams), or the immunoglobulin can be incorporated into conventional dentrifice prepns. The reconstituted milk can also be used as a simple drink which inhibits the formation of colonies of Streptococcus mutans.

Title: Gas compression or vacuum forming pump - creates compression or vacuum without aid of moving parts by gas repulsion effect at electrodes
Inventor: WEMHOENER WILHELM
IPC: H01J41/12
Filed: 1975-06-28
Abstract: A pump may be used either for compressing a gas or producing a vacuum.

Title: Automatic short-wave transmission - uses digital clock generator output to control transmission frequency to minimise effect of interference
Inventor: RIEWEL RUDOLF VON
IPC: H04B1/50
Filed: 1975-08-21
Abstract: A short wave radio communication system has an automatic facility for modification of bandwidth and transmitting frequency when interference is encountered. A card reader controls the generation of a range of digital clock frequencies controlling a synthesiser generating a range of short wave radio frequencies. The output of the clock generator is coupled to a computation unit, also connected to a dialling facility for selecting the station with which communication is required. The computer output is coupled over a memory and an encoder. A detector monitors operating frequencies together with a decoder. Any interfering frequency signals that are detected result in a narrowing of band width or a change to another transmission frequency.

Title: Press. measurement in corrosive and viscous medium - necessitates indirect measurement using compensation pressure generated by electrically heating fluid
Inventor: ROEVER MARTIN DR ING
IPC: G01L7/08
Filed: 1975-08-23
Abstract: A device for the measurement of press. in a corrosive or viscous medium necessitating separation of the press. sensitive element from the medium by a membrance is desgned to produce exact measurements independent of the stiffness of the membrane using compensation press. techniques. Such conditions require a small membrane of very stiff material. The effects of the membrance characteristics are nullified by maintaining its position constant. The press. exerted on the membrane (M) by the medium (V) is transmitted to the rod (St) connected to the lever (H). When the lever (H) is forced upwards it closes an electrical contact (5) causing current to be passed through the heating element (W) in the fluid (F1). The fluid expands or evaporates, exerting a downward force on the rod (St) until the contact (5) opens at the nominal membrane position. The fluid press. indicator (MP) displays a measure of press. in the medium (V).
