Title: Forming fabric by pressing between table and positioning platform - and locating pressure element between table and platform
IPC: B29C51/00
Filed: 1974-05-13
Abstract: A fabric panel to be formed into a given shape is pressed between a work table having pref. apertures and a positioning platform which pref. also has apertures aligned with the apertures in two work tables and which is pref. fixed so that the table can be moved quickly to clamp the panel against the positioning platform. A pressure equalising element is located between the work table and positioning platform to ensure a uniform pressure is exerted on the fabric panel during forming. Pref. forming is effected by using mould elements to force the fabric panel through the apertures. The device is used partic. for moulding the cups of brassieres. Creases around the formed regions of the panel are eliminated.

Title: Combined thermostat and temperature fuse - is for deep-fryers when rapid interruption is needed on breakdown
IPC: H01H37/76
Filed: 1974-08-02
Abstract: The combined thermostat and temperature fuse consists of a bimetal strip for sensing temperature. There is a rapid detent spring with electric switch contacts and a temperature fuse, comprising a cartridge of fusible metal, a plunger with one end embedded in the fusible metal and the other end pressing a spring with electric switch contacts. All the metal parts are in direct thermal contact with a rivet and collar which can be mounted onto the surface whose temperature is to be controlled. The thermostat and the temperature fuse operate independently of each other. The thermostat regulates the temperature by switching a heating current passing through the switch contacts and the temperature fuse over-rides these switch contacts, in case of breakdown, by fusion of the metal, ejection of the plunger and separation of the fuse switch contacts.

Title: Floating oil storage bladder - made of stiff polyethylene strips of low specific gravity without reinforcement
IPC: B65D88/34
Filed: 1975-03-19
Abstract: A storage reservoir for oil is assembled from plastic strips to float on the surface of a water basin within a dam made waterlight by a lining of plastic sheeting.
