Title: Solar collector - Has several porous layers of different spectral transmissivity arranged in hollow absorber, through which energy-carrying medium flows
Inventor: SCHMIDT MANFRED PROF DR ING
IPC: F24S10/80
Filed: 1992-10-16
Abstract: A solar collector consists of a hollow radiation absorber through which an energy-carrying medium (1) flows. The absorber is made from several porous layers of material (2) of different spectral transmissivity. The layers are arranged so that the outside one admits preferentially the longer wavelength infra-red radiation, and each succeeding one admits a shorter wavelength. The flow of the medium is in the direction of increasing temperature gradient. Apart from the entry and outlet spaces (3, 4) for the medium, the multi-layer absorber occupies the full volume of the collector almost completely. The ability of the layers to be pigmented can be adjusted according to the required absorption properties. Suitable materials for the layers are glass granulates and sedimented glass sand. ADVANTAGE - Increased solar energy transmission to fluid medium.

Abstract: The invention relates to a glass vessel (1) for containing hot beverages, the glass container (2) of which having, at its upper end (23), an opening (28) bounded by a rim (34). Fixed to the rim (34) is a plastic ring (30) which is equipped with a pouring spout (39) and is composed of a first (31), second (32) and third (33) ring. The third ring (33) bounds the opening (28) from outside. The second ring (32) is supported from above against the rim (34) of the glass container (2). The first ring (31) engages with the aid of resilient fastening elements (35) into the opening (28) of the glass container (2) from above. A constriction (26), running around annularly, is formed on the glass container (2) below the rim (34). The fastening elements (35) engage resiliently behind the constriction (26) from above and lie flush against the inner wall (27) in the region of the constriction (26). Both the third ring (33) and the first ring (31) run at a distance from the opening (28). As a result, even in the case of frequent temperature action over a long time a firm seat of the plastic ring (30) on the glass container (2) is achieved. <IMAGE>

Title: C frame for tool closure units of injection moulding machine - has single cast main frame comprising two side frames, upper forward projecting front frames, front frame between side frames and tensioning pillars
Inventor: MIYAHARA MASAAKI
IPC: B29C45/17
Filed: 1993-01-30
Abstract: C-frame comprises a coast main frame. The frame has two opposing side frames each with an upper, forward projecting frame and also a front frame extending between the side frames. Tool closure cylinder is located in both upper frames. Both side frames, upper frame and the front frame form a single casting. Cast or steel plate forms a base plate connected by bolts to the lower end of the main frame and completes the C-shape. Two steel pillars extend through the transition area between the two side frames and the front frame. Pillars are tightened against the C-frame at the top and bottom by the threaded lengths and nuts. A hole (6) in each of the transition areas between the side frames (2) and front frame (4) accepts the pillars (10). The transition areas are therefore very thick. Pre-tensioning of the main frame (1) is achieved by tightening the nuts (13) on both pillars (10. Pillars (10) may be designed with an internal recess to accept a cartridge heater which extend the pillars (10) by expansion prior to pre-tensioning. The C-frame (1) may be vertically or horizontally aligned on the machine bed of an injection machine.

Title: Process for the preparation of ketones by transesterification with trifluoroacetic acid
Inventor: BRAUN MAX DR
IPC: C07C49/167
Filed: 1993-06-24
Abstract: There is described a novel process for the preparation of ketones, for example CF3C(O)CH3, CF3C(O)CH2C(O)CF3 and CF3C(O)CF2H, in which beta -keto esters are transesterified with trifluoroacetic acid and decarboxylated. The process is carried out under anhydrous conditions, which is why no acetals or hydrates are formed, thus dispensing with the necessity of a dehydrating step. A further advantage of the process is its simplicity.
