Title: Friction wheel drive for torque converter - mushroom shaped rotating heads for opposing shafts with conical interconnecting drive
Inventor: MORI KIYOSHI
IPC: F16H13/04
Filed: 1975-08-27
Abstract: A torque converter drive which does not use spherical rotating members with high friction coefficient has two concentric shafts which fit in the housing, projecting at opposite ends and at the other end fitting into a rotating mushroom shaped head. These are in contact with a truncated cone shaped friction surface with the tapered end fitting inside the mushroom head of the other shaft. There are spheres between both the rotating heads and both friction surfaces are simultaneously in contact. The ratio of input to output speed is proportional to the ratio between the cross sections of the roating components. Alternatively one shaft rotates inside the other shaft, both fitting in the same direction in the housing.

Title: Step motor control system - has impulse generation and selection according to program for sewing machine
Inventor: SUGIYAMA AKIRA
IPC: G05B19/40
Filed: 1975-08-27
Abstract: An appts. is claimed for the control of a step motor, partic. for a sewing machine, with a drive circuit to generate activating signals to the step motor. A store holds the information on the number of impulses and the impulse sequences for the drive circuit to pass on successively. A reader extracts the stored information data, while a decoder establishes the number of impulses in a sequence. An impulse generator delivers a frequency, selected from an available number of frequencies, to match the decoded impulse information. The generated impulses are fed to the drive circuit where a digital unit stores the number of impulses through the decoded impulse sequence, with gates to end the impulse supply when the number of fed impulses matches the stored number of impulses. The system provides a simple method of activating the motor to operate at a given and determined number of rotations, at high speeds, with a positive stop action without requiring absorbers for vibration.

Title: Hot rolling operation for tubular steel rollers= - locates blanks between tapers and form rollers mounted on swivel arms
Inventor: FALCOZ GIOCONDO
IPC: B21H1/06
Filed: 1975-08-30
Abstract: To produce tubular steel rollers from cylindrical blanks, a roller press is used. The press has two tapered pins in axial alignment such that a heated blank can be clamped between them. Three coplanar driven rollers (12) on swivel arms (11) are then forced against the outside diameter of the blank during the rolling operation. The roller arms (11) are linked together by levers so that a single hydraulic cylinder produces synchronised motion. The form rollers (12) can have different shapes so that steel rollers of various profiles can be produced.

Title: Procedure for determining zones of tectonic forces - involves thermocouple measurements and plotting force magnitude and location
Inventor: EHRHARDT WILHELM DR ING
IPC: E21C41/16
Filed: 1975-10-03
Abstract: The procedure for determining zones in a strata has the reduction in tectonic forces influenced either naturally or by artificial obstructions. The size and the position of the still-remaining tectonic forces is determined by a construction or by measurements. In the strata being examined, boreholes are driven for insertion of thermocouples or resistance thermometers. The measured temperature or the energy values are recorded by a point writer with a very small paper advancing speed. The zones and border lines resulting from these values are entered on a card covering man-made obstructions and alterations, line of extractions and rest pillars. The boreholes are lined with pipes and connected to a vacuum. The extracted gas is measured and recorded. The corresponding border lines and zones are again entered on the card.

Title: Prodn. of low concn. emulsions - from viscous concentrates using double mixing to first prepare strong emulsion
Inventor: MUELLER HELMUT
IPC: B01F3/08
Filed: 1975-11-03
Abstract: Emulsions are prepd. from a viscous concentrate and a carrier liq. by feeding both liquids in metered proportions to a mixing chamber. The emulsion is first formed as a high concn. of concentrate in the carrier. This is then further dilated in a second stage to give the concn. needed The first emulsion is pref. created in a jet mixer device. This discharges into a mixing chamber to which more carrier liq. is added. Process is used in mfr. of cooling and lubricating emulsions for metal working. These are water suspensions of a viscous lubricant. Very dilate emulsions have the problem that if the lubricant is metered into a jet mixer at low rates, the metering device can cause periods where the jet pump is pulling a vacuum. The present method thus avoids the problem of clear water passing into the emulsion vessel, which can cause pivotable emulsion, damage to cutters and workpiece etc.

Abstract: The lathe has a rotating tool carrying turret arranged in front of the headstock spindle which carries the workpiece. The turret is held on the free end of a support projecting from the machine stand. The stability of the turret is improved independently of the stiffness of the overhanging support. The length of the moment arm of the tool carrier (6) from arm free end to the tool (W) cutting edge is related optimally to the length of the moment arm length. This ensures that the feed force and the cutting force.
Patent DE-2619323-A1 (DE)
Title: Stack wrapping machine in plastic strip - has iron welding blade for joining loop ends kept at constant temp. while working
IPC: B65B13/02
Filed: 1976-04-30
Abstract: The machine wraps stacks of rectangular packages in plastic strip passing through a gap in a table between rolls above and below the table and held taut. The strip forms a loop around the stack as it is thrust under a pressure finger, the bottom run of the loop passing over a further gap in the table accommodating a welding blade. The top run is pressed down by the finger onto this gap, so that the two ends can be welded together as a holder keeps the stack stationary. The weld seam is then divided and the loop around the stack parted off. The welding blade (15) is kept as nearly as possible at constant temp. while the machine is working. It can be of stress-relieved grey cast iron.
Patent DE-2620346-A1 (DE)
Title: Rapid braking of async. squirrel cage motors - is achieved by short circuiting of stator windings and by switching loading resistors into one or more phases (NL 9.11.77)
Inventor: HANSEN HERBERT
IPC: H02P3/22
Filed: 1976-05-07
Abstract: The object is to give reliable and rapid braking under conditions of low or extreme temperature which can adversely affect conventional magnetic brakes. The braking is accomplished by short circuiting the motor stator windings (1, 2, 3) immediately following disconnection from the supply. To give a measure of control loading resistors (13) may be incorporated either in one phase only or in all three. The stored magnetic energy is thus utilised for retardation. The switching of supply and short circuits can be accomplished by the use of triacs. This contactless form of control is especially useful where many operations are required, and it also gives fast switching times.

Title: Motor windage losses reduction system - operates by encapsulating end windings to give smooth contour and casing is filled with thermally conducting material
Inventor: MEHRMANN FRITZ
IPC: H02K3/38
Filed: 1977-03-22
Abstract: The system is used with slotted armatures, and is intended to reduce the windage losses, principally from the end windings. The ends of the coils (5) are covered with an encapsulating medium (8) which is given a smooth external contour to minimise windage losses when the motor is running. The encapsulation is normally loaded with thermally conducting material in order to maintain the cooling of the winding ends. The encapsulation can also, and with advantage, be extended to cover the armature core and slots (2, 4) thereby reducing the windage effects of the slot openings. The encapsulation may be applied by spraying or casting. The filling material is typically glass fibres, or glass balls with a diameter of hundredths of a millimeter in order to facilitate flow during application.
