Title: Stain-removing paste - contg. silica encapsulated in gelatin hardened with formalin to improve heat resistance
Inventor: SCHMIDGALL HEINZ DR
IPC: C11D17/00
Filed: 1975-07-21
Abstract: Parent Patent describes a process for packing a pasty spot remover (I) in individual portion capsules. Gelatin is used as the raw material for the press.-mouldable capsules. The spot remover contains no water. Use of a lower alcohol is avoided as far as possible. The improvement comprises hardening the ready, filled capsules by soaking in a formalin bath. Pref. the compsn. of (I) is modified to incorporate SiO2 having defined chemical and physical properties, i.e. pref. paste contains 6-13%SiO2FK300DS. Hardened capsules have improved heat-resistance, e.g. up to 80-85 degrees C. Hardening increases brittleness of gelatin and facilitates opening of capsule.

Title: Clamp for securing conductor to support - uses spring clips or buttons with conductor retained by saddle clamp
IPC: F16L3/10
Filed: 1975-09-06
Abstract: The clamping arrangement is primarily intended for securing a lightning conductor to a support plate or stud fastened for example to a building wall. The conductor (4) is held by a saddle clamp (3), or other suitably formed device, which has projections (6) at each end and opposite each other. They are formed to have hooks and, being made of an elastically deformable material, can snap over the base plate (2) attached to the support stud (1). In addition, or alternatively, the clamp may also have projecting elastic buttons (10) which have a collar (12). When pressed through holes in the base plate (2) the collar holds the clamp in position. Use of this type of fastening makes for a quick and easy assembly as the need for making bolted joints is eliminated.

Title: Telephone monitor circuit system - has automatic on and off switch and uses metal-oxide silicon gate as control element
Inventor: LAU MANFRED
IPC: H04M1/215
Filed: 1975-09-05
Abstract: The telephone monitor with an automatic electronic on/off switch comprises an induction coil, low-frequency amplifier, loudspeaker and electronic switch. The operating current for the monitor is switched by a transistor. The transistor is controlled by a C-MOS gate which in the unenergised condition draws no supply current. Operation of the telephone apparatus, causes the gate to conduct and switch-on the transistor. This supplies the necessary current to the monitor circuit. When the telephone is replaced, the alternating current in the induction coil falls and the gate disconnects the transistor.

Filed: 1975-09-16
Abstract: Solidification of opt. toxic, finely divided or dissolved materials from waste waters. The waste waters or the dissolved and/or dispersed contaminants in waste waters and/or contaminants removed from waste waters are concentrated. The concentrate is mixed with fillers and/or binders and also with chemical aggregates which prevent re-dissolution of contaminants. Compsn. is subsequently heat-hardened, as a raw material. Contaminants are converted to non-toxic or permanently insoluble cpds. The raw materials can be pressed to blanks and used as building materials. Transport and deposition of blocks is facilitated.
Patent DE-2544420-A1 (DE)
Title: Electronic logic control for DC traction - with servo driven current regulator and modulated smooth adjustment for braking
Inventor: BISKUP KONRAD ING GRAD
IPC: H02P1/20
Filed: 1975-10-02
Abstract: The DC traction is controlled by a stepping switch over a series of resistances, with the stepping operated by a servo driven cam. A logic control compares the actual motor current with a reference value and adjusts the current accordingly. In order to provide a smooth control the braking effect is smoothed. If the reference current is greater than the actual current then the servo increases the current directly. If the reference current is lower than the servo action is modulated to smoothly change the motor current and prevent sudden torque changes.

Title: Protective cover for horseback - has soft perforated corrugated plastics layer giving ventilation when used under saddle
Inventor: HAMPICKE WILLI
IPC: B68C1/14
Filed: 1976-03-31
Abstract: The protective cover to be used to protect the back of a horse, especially for placing under the saddle is a mat (10) of soft plastics material with rows of holes (11) through it, and a corrugated surface, the holes being through the sunken parts (14) between the corrugations. In an alternative design, both sides are corrugated. When a rider is seated on the saddle, the rising and falling motion tends to circulate air through the cover, cooling the horse's back and dissipating sweat. Reinforcing fibres (23) can be incorporated, also straps to secure the cover. The material can be formed as a sleeve to form a saddle girth. A felt layer may be attached to one or both sides.

Title: Expanding multiple link wristband - has resiliently hinged links with right angled hinge arms connecting adjacent links
Inventor: MANDERLA GUENTER
IPC: A44C5/08
Filed: 1976-05-11
Abstract: The design concerns a wrist band for use on wrist watches. It consists of links hinged together under the action of leaf springs. The band is expanding and the links are replaceable. The links are box-shaped and held together by hinge arms (2). The box-shaped element narrows at one side of its cross section by a shoulder (3), so that on two adjacent elements a gap forms which accommodates the hinge (9) connecting the two adjacent boxes. Part of the length of the element, equivalent to the width of the wrist band, is nearly closed up by legs with a gap between the two opposing legs. The gap is sufficient to take up the thickness of the hinge arm with its angle part (16) resting against the press. of a leaf spring (13). The arm outside the box elements is fitted with fulcrum elements with a gap between, into which the corresp. shaped fulcrum part of the adjacent hinge arm fits.

Title: Heat-shrinkable plastics film package - comprises top and side portions, with additional protective film over top portion
Inventor: THIMON MICHEL
IPC: B65D71/00
Filed: 1976-06-16
Abstract: Wrapping of heat-shrinkable plastics film comprises a horizontal top portion arranged upon the contents to be wrapped, and a mantle surrounding the vertical sides of the contents. An additional piece of film for protecting the contents from outside agents is fastened at the top of the wrapping. Used for wrapping and protecting light- (esp. U.V.-) and dampness sensitive goods stored in the open air. Instead of using expensive U.V.-resistant film for the whole package it is sufficient that only the additional piece of film on top of the package is made of this relatively expensive material whilst the rest of the wrapping can be of cheaper standard e.g. polyethylene, film.
