Title: Stuffed meat olives prodn. - mechanised by extrusion of core of stuffing in sleeve of compressed meat scraps
IPC: A23L13/60
Filed: 1973-03-16
Abstract: The stuffing and the meat are extruded simultaneously and at the same speed from a single nozzle having an axial passage for the stuffing and a surrounding, coaxial, annular passage for the meat. Both passages are convergent to compress the extruded materials, and this action also tends to orientate the scraps of meat in planes at right angles to the axis of extrusion. As extruded, the product is sleeved in a tube of food quality skin to hold it together whilst cut into lengths which are then frozen, stripped of the skin and cut into finished pieces, i.e. meat-olives, ready for cold storage. Suitable meat scraps include beef, pork, veal, chicken, etc. Constant cross-section of the olives facilitates wt. control, makes cooking easier and ensures consumer satisfaction.

Title: Adenine derivs for stimulating root-formation in trees - comprise the 9-substd. adenines, prepd. from adenine and corresp. halide
IPC: A01G23/04
Filed: 1974-06-25
Abstract: Root-formation of trees (e.g. side-rooting in transplanted trees) is stimulated by applying 9-substd. adenines of formula (I): (where R is lower or medium alkyl, alkenyl or phenylalkyl), e.g. 9-benzyladenine, to bark-free areas or cuts on the stem, branches or roots of the trees. The method of root stimulation can be used in the air-layering method of progating trees, to stimulate side-root formation in trees transplanted with only a few roots intact, or to improve water-uptake in specimens where for aesthetic reasons it is undesirable to reduce transpiration by the usual method of removing foliage. (I) can be prepd. by treating a soln. of adenine in e.g. DMSO with R-X (X = halogen), adding anhydrous K2CO3, reacting 3 hrs. at 50-60 degrees C, removing solvent, and recrystallizing the resulting crude prod.

Title: Wrapping large articles in plastics film - by winding film strip around them and sealing the over-lapping edges
IPC: B65B27/10
Filed: 1974-06-27
Abstract: One or more plastic film webs are spirally wound about an object to be wrapped, in overlapping relationship and the overlapping edges of the film(s) are sealed together.

Title: Constant speed control of motor - speed transducer output compared with reference to control current to coupling coil
IPC: H02P29/00
Filed: 1974-09-20
Abstract: The current supply to a magnetic particle coupling between a motor and output shaft is regulated by a control circuit and output shaft is regulated by a control circuit to provide a constant speed. A second arrangement enable two constant speeds to be achieved within one operating cycle. The output shaft of the drive carries a speed sensor in the form of a disc (22) that has apertures sensed by a detector (23). The pulsed output of the detector is transmitted to an amplifier (30) over a pulse rate doubling circuit (29). The amplifier output is integrated and is compared (26) with the output of a reference input potentiometer (25). The difference signal may be used to provide control of the current to the magnetic particle coupling (7) coil to maintain constant speed.
