Title: New firm white cheese - mfg process
IPC: A23C19/032
Filed: 1970-11-06
Abstract: The milk, after being heated to 80-90 degrees C, is allowed to cool to 45-55 degrees C. a ferment of the type usually used for the mfr. of yogurt is added and the batch is incubated for 12 hrs. at 22-24 degrees C. The ferments will by then have produced their effect and a curdled milk is obtd. having a taste and a consistency different from those of yogurt. This curdled milk is drained by placing it on a fine-meshed fabric where it is left for 12 hrs. to remove the whey. Drying is completed by maintaining the paste under press. in a press or under a wt. for 12 hrs. salt, spices and possibly aromatic materials may then be added. They are stronger than the usual white cheeses and the risk of crushing during handling is thus reduced.

Title: Bonded foundry sand moulds - by pressing a pattern into an incompletely hardened moulding material mass
IPC: B22C11/08
Filed: 1972-12-29
Abstract: The moulding material is formed into a bed of constant thickness on the upper surface of a conveyor and preferably passes between breadth confining plates. At a stamping station the conveyor is intermittently stopped and a pattern is brought down into the moulding material bed to punch an impression. Blades at the front and rear of the pattern may separate the punched - out moulding from the bed. The binder which is preferably less than 10% by weight of sand may comprise an isocyanate resin or a hydroxyl containing core - oil such as an oil - modified alkyd resin. These may be used with a primary polymer binder. A alkali - metal silicate binder may be employed e.g. with a hardening catalyst. The binder may be heat or gas - hardened but should harden progressively so that the moulding mixture can be brought to a condition in which it may be deformed by pressing but is hard enough to maintain the pressed shape on standing.

Title: Pulse generator for machining metals by spark erosion - switchable oscillating charge and discharge circuits control pulse parameters
IPC: B23H1/02
Filed: 1973-06-12
Abstract: The charging circuit consists of a battery from which current travels via a choke (3), a control valve (6), a second choke (4) to the storage capacitor (1) and back to the battery (2). The positive pole of an electrolytic capacitor (5) is connected between (3,6), and its negative pole between (1,2). A switchable oscillating circuit is thus formed by (1,5,6,4). On the discharge side, one lead goes to two valves (12,13) connected in antiparallel and then to one input terminal (a) of a full-wave rectifier (11); the other lead on the discharge side goes via a choke (8) with a shunt capacitor and resistance to terminal (b) of (11). The output terminals (c,d) of (11) go to the electrode and part being machined (7). A second, switchable oscillating circuit is thus formed on the discharge side by (1,8,7,12,13). The circuit parameters are chosen so that the period of resonant oscillation in the discharge circuit is 3-20 times that in the charging circuit. By this means, a substantially independent control of the pulse parameters (current and voltage amplitude, repetition frequency) can be obtd.

By using pair of half moulds for the body and several different pairs of half moulds for the neck (or vice versa) a varsity of different shaped bottles can be produced. The cost of providing moulds to provide a variety of different shaped bottles is reduced.

Title: Lace with cable patterns whose sinuous edges have loop fringes - loops of adjacent cables being traversed by chain stitching
IPC: D04B21/10
Filed: 1974-03-29

Title: Laminated film plates - from films of varying dimensional stiffness
IPC: B32B7/022
Filed: 1974-08-30
Abstract: Mfr. of laminated film plates from films of differing dimensional stiffness, by spreading a less rigid film e.g. a smooth film on a first table on which it is bonded to at least one film of greater dimensional stiffness e.g. a corrugated film, accurately ffitted to form a unit, which is then advanced to a second table where a series of such units are accurately superimposed and bonded to form the laminated plate. More especially, the film of lower dimensional stiffness is drawn from a stock roll, from which it is cut off after bonding to the stiffer film. The method provides a rational process for laminating films of differing stiffness at improved production rate and with minimum handling difficulties.

Title: Model for process control - for prediction of future values of inaccessible control magnitudes in e.g. distillation
Inventor: LANDAU IOAN-DORE
IPC: G09B25/02
Filed: 1975-05-22
Abstract: Model comprises in series a generator of a function (G), receiving the output vector (X) of the model and/or of the process, with an integrator. A parameter vector (P) defines the parameters of the model and if required, an input vector (U) for the process and the model. The model produces a vector G (X, U, P) equal to the derivative with respect to time of the vector, (X) while the output of the integrator is connected to the output of the model. The parameter vector (P) is generated in a computer block comprising at least (a) a multiplier which multiplies a generalised error vector (E) equal to the difference between the output vectors of the model and the process, by the matrix of the partial derivs. of the components of the vector (G) with respect to components of the parameter vector (P). It further comprises (b) an integral chain following the multiplier and formed by putting in series, a matrix of adaptation and an integrator the output of which is connected to the output from the computer block which gives (P). The model can be adapted at every instant so that it reflects the actual characteristics of the process. The unmeasured fundamental magnitudes can therefore be evaluated very much more precisely and an estimate-free from background noise - of the variation of these magnitudes can be integrated t provide their predicted future values.
