Title: Process for production of instant mashed potato products of varied bulk densities from a foamed slurry of cooked potato solids
IPC: A23L19/15
Filed: 1967-04-14
Abstract: A process for preparing a dry instant mashed potato product comprises preparing an aqueous damage-free, debris-free potato slurry and either (a) producing a stable wet foam from the slurry, drying (e.g. on a drum) a major portion of the west foam and mixing the dry foam portion with the wet foam portion to form a damp mix or (b) dividing the slurry into a major portion and a minor portion, adding milk to the minor portion, forming stable wet foams from each portion, drying the major foam portion and mixing the dry foam portion with the wet milk-containing foam portion to form a damp mix. The damp mix has a 60-65% by wt. moisture content. The damp mix may be predried to about 30% by wt. moisture content, granulated or mixed with or without retrogradation and finally dried to about 7% moisture content. The slurry may be formed by mashing precooked, cooled and cooked potatoes in water containing butylated hydroxytoluene sulphites, monoglycerides and chelating agents. The slurry is foamed in the presence of gas (e.g. air).

Title: Apparatus to control gravitational movement of a gem stone polishing tang towards a stone polishing surface
IPC: B24B9/16
Filed: 1967-12-19
Abstract: A dashpot 6 for controlling the gravitational movement of, for example, an arm 1 in a gem polishing machine is connected by a flexible tube 7 to an upstanding tube 8 which is movable vertically to adjust the position of balance of the dashpot plunger 5. The tube 8 is raised or lowered by a motor 9 controlled by movements of the arm. When the arm is lowered, a follower 4 on the arm engages the plunger 5 before the gem held by a dop or chuck 2 engages a polishing wheel 3. The weight of the arm gradually depresses the plunger as the gem is polished. If the arm is light or counter-weighted, its pressure on the plunger may be insufficient to move it sufficiently from its initial balanced position this difficulty is overcome by the automatic lowering of the tube 8 so that liquid (e.g. mercury) flows out of the dashpot. After polishing, the arm is lifted off the wheel and dashpot, the tube being quickly restored to its original position causing liquid to flow back into the dashpot. A restriction valve 12 in the tube permits the liquid to flow more rapidly into, than out of, the dashpot.

Title: Hybrid circuit breaker having means for detecting the leading edge of the arc voltage at the contacts thereof
IPC: H01H9/30
Filed: 1968-08-16
Abstract: A "hybrid contactor" comprises an electromagnetic contactor B, P, a shunt thyristor Th1 connected across the contacts P, a second thyristor Th2 to discharge a blocking capacitor C through the thyristor Th1, and an arrangement for controlling the thyristors so as to prevent or minimize arcing at the contacts, this arrangement including a differentiating circuit A1 to derive a signal for triggering the thyristor Th1 from the leading edge of the voltage pulse arising across the contacts P when opened. This signal is applied through a monostable vibrator A2 and amplifier A3 to the control electrode G1 of the thyristor Th1 to cause the thyristor Th1 to conduct. The signal from A3 is also applied to a second differentiating circuit A4 which differentiates the trailing edge of the signal to produce an output, which through an inverter A5, a gate A6, and an amplifier A7 triggers the thyristor Th2 after a delay imposed by a resistance capacity circuit C4, R13 in the inverter A5. The thyristor Th2 conducts to permit the capacitor C to discharge through and block thyristor Th1. If however the opening of the contacts P was due to contact bounce, the control switch I for the coil B being closed, then an inverter A10 applies a blocking signal to the gate A6 to prevent the operation of the blocking circuit Th2, C, the thyristor Th1 ceasing to conduct when the contacts reclose. A differentiating circuit All, an amplifier A12 and a pulse transformer A13 control a third thyristor Th3, through which the capacitor C is charged. The supply for the transistors in the various circuit elements is provided by a capacitor Cl which is charged from the contactor coil supply through switch I and discharged by a thrystor Th4 which is triggered on at the end of an opening operation by the signal from amplifier A7.

Title: Mud actuated drilling tool
IPC: E21B4/14
Filed: 1975-06-13
Abstract: A fluid operated impact drilling device wherein a hammer is mounted in a casing for axial reciprocating movement and drilling fluid flows through the hammer. The flow of drilling fluid is controlled by a valve element at the upper portion of the hammer. Differential pressure areas are provided in the flow path of the drilling fluid which coupled with the action of the valve element causes the hammer to be repeatedly lifted up into the valve element and then driven downward against an anvil by the force of the drilling mud. The valve element remains partly open, thereby preventing excessive backpressures from damaging the drill pipe or equipment. The drilling device is attached immediately above the drill bit with the drill bit being secured to the anvil. A catcher device is mounted to stop the reciprocating impact action of the hammer against the anvil upon picking the bit up off bottom.
