Abstract: 1,082,594. Sterilized concentrated milk. NODAWAY VALLEY FOODS Inc. June 2, 1965 [June 22, 1964], No. 23598/65. Heading A2D. [Also in Division B8] Aseptically canned milk is prepared by a method comprising concentrating and sterilizing skim milk, mixing sterile butter oil with the sterilized milk and aseptically canning the mixture. Whole milk is centrifuged at about 45F. to produce cream and skim milk, and the cream is churned to form butter. The butter is melted and centrifuged, and the thus separated butter oil is passed through a sterilizing filter. The skim milk is preheated and passed to an evaporator to increase its solids content to 26 to 27%, cooled and stored. The concentrated skim milk is passed from storage through a sterilizer into a homogenizer where it is mixed with the sterile butter oil and homogenized first at 4,000 to 5,000 p.s.i.g., held for a few minutes, and then rehomogenized at 500 to 1,000 p.s.i.g. The homogenized milk is regeneratively cooled, and is both filled into sterile cans and sealed under a sterile nitrogen atmosphere. A sterilized antifoaming agent, such as butter oil or a silicone, is sprayed on to the surface of the milk as it is being filled into the cans. The separation of the butter oil from the cream reduces the phospholipid and cholesterol content of the final product, further reduction of which may be effected by subjecting the skim milk to a second centrifugal separation at about 90F.

Title: Logic system for print ball tilt control
IPC: G05B19/40
Filed: 1975-06-02
Abstract: 1463788 Automatic control BURROUGHS CORP 2 June 1975 [1 July 1974] 23803/75 Heading G3N [Also in Division G4 and H2] In an open-loop digital logic system for setting the tilt position of a print head, a portion of data storing means is addressed in response to desiredprint-head-tilt-position data to read-out predetermined print-head-tilt-position-changecommands data in response to which timed sequencing through the addressed portion occurs energizing sequentially the appropriate phases of a multi-phase stepper motor mechanically coupled to the print head to produce a smooth transition of the head to the desired tilt position. Tilt positioning of a print head, ball, is controlled by a four-phase variable reluctance stepper motor-controlled from a readonly memory. Two bits specifying the new desired position are loaded via a 2-bit latch into a "new position" part of a shift register and used in conjunction with an "old position" part of the register, loaded with the previous contents of the "new position" part, and a first binary counter, set at zero, to address the read-only memory to read out an 8-bit word. Four bits of this control respective phases, stator winding pairs, in the motor and the other 4 pre-set a second binary counter which is now counted to capacity by clock pulses to define a time period for which the windings are to remain energized under control of the current word. At capacity, the second counter increments the first counter to obtain another word from the memory to control the windings and pre-set the second counter again, and so on until the first counter reaches capacity. Thus the number of words used for a position change is always the same, so in some cases not all the words will be needed to reach the desired position: in these cases the last so many words involve energization of phase one only, this defining a detent position, and pre-set the capacity count into the second counter, except for the last word which pre-sets "zero" in order to prepare for the next position change. The pre-set values are chosen from experiment to substantially eliminate overshoot and oscillations. When power is first applied to the printer, the shift register is initialized to cause a maximum forward movement attempt by the print head, to a mechanical stop. Phase one of the motor is D.C. coupled, for detenting when not rotating, but the other phases are A.C. coupled, to prevent burn-out if, due to failure, too many phases are energized for too long.

Abstract: 360,857. Electric clocks. SCHLENKER, A. E., 19, Fabrikstrasse, Schwenningen-on- Neckar, Germany. Aug. 11, 1930, No. 23980. [Class 139.] A device for electromagnetically raising a weighted lever driving the clock in which current is controlled by a contact pin on a spring-controlled lever bearing on the edges of coaxially pivoted conducting and insulated segmental plates in such a manner that the movement of the currentcarrying plate during the operating stroke of the electromagnet raises the contact pin off a shoulder on the spring-controlled insulating plate so that the latter in turn when released rotates to raise the contact pin from the conducting plate and break the magnet circuit, is provided with an adjustably mounted guide on the insulating plate to vary the period of contact between the contact pin and the conducting element. As shown in Fig. 1, the weight lever 8 is mounted rigidly on the shaft carrying the electromagnet armature and is connected by an insulating pin 9 to a pivoted conducting segment 1 on the edge of which normally bears a contact pin 3 carried by a pivoted spring- controlled arm 2. The pin 3 also engages a shoulder on the edge of a co-axially pivoted insulating plate 4. During the operating stroke of the electromagnet to raise the weight lever 8 the contact pin 3 rides on the inclined face 11 of the plate 1 until it is raised sufficiently to clear the shouldered portion of the insulating plate 4, Fig. 2, when the insulating plate 4 snaps across under the action of a spring 5 by the amount permitted by a slot 10 therein over the connecting pin 9 so raising the contact pin 3 from the conducting plate 4, Fig. 3, and breaking the electromagnet circuit. To vary the period in which the pin 3 remains in contact with the surface 11 of the conducting plate 1 the insulating plate 4 carries a pivoted metal arm, Fig. 7, secured thereto by screws 4a, 4b and formed with a slot 7a, so that it may be adjusted to various angular positions to vary the amount of lift necessary to raise the pin 3 past the shoulder on plate 4. Current is led to the plate 1 through a blade spring 12 bearing on a pin 13 projecting laterally from the plate.

Abstract: 635,819. Dish-washing machines. STEENBERG, A. C. Jan. 8, 1946, No. 24302/48. Convention date, Dec. 29, 1943. Divided out of 635,755. [Class 138 (i)] [Also in Group XXX] Rigid-surfaced articles such as crockery are cleaned of fatty and sticky matter by subjecting the surfaces of the articles to jets of dry or superheated steam in a confined space, and simultaneously removing the steam by suction. The articles are put into a steam chamber 12, in a casing 10, along guides on a bracket 34 and then they are carried vertically between conveyers 26, 28. Steam under pressure is projected through a series of nozzles fitted to pipes 56. The steam is removed downwardly, by an exhauster 80, from the chamber 12 through a gap 14 into a lower chamber 16. This arrangement prevents dirty steam contacting cleaned or partly cleaned articles. The pressure in the chamber 12 is kept about atmospheric. The last nozzles of the series are situated near the point of removal of the articles to prevent steam condensing on them. The upper conveyer is vertically adjustable, through mechanism operated by a hand wheel 52, to accommodate various sizes of articles. The nozzles are also vertically adjustable by an associated mechanism which provides that the nozzles are situated half-way between the conveyers. The nozzles are oscillated, to project the steam from the upper to the lower edges of the articles, through mechanism connected to driving gear 22. This mechanism is so arranged that the amplitude of the oscillations is dependent on the distance between the conveyers. A sludge container 18 is provided. Specification 635,755 is referred to.
