Title: Measurement of intracardiac and intravascular pressure - with automatic control of reference pressure value for ease of operation
IPC: A61B5/0215
Filed: 1969-05-23
Abstract: Apparatus for measuring and/or recording intracardiac and intravascular pressure comprises a hollow catheter to one end of which is connected a mechanical-to-electrical pressure transducer, maintained in pressure contact with the measuring point by liquid filling of the catheter. Connected to the output of the transducer via an electroconductive connection is a carrier frequency amplifier with automatic zero balance means.

Title: Ultrasonic transducer array for weld fault finding - enables faults of different orientations to be detected by use of two pairs of transducers one pair facing common interface
IPC: G01N29/30
Filed: 1969-10-17
Abstract: The methods are for monitoring ultrasonic transmissions, and of receiver and transducer arrangements in simple arrays for detecting faults or irregularities in test pieces, particularly welded joints. The arrangements allow test piece faults to be detected largely independently of quality of coupling between the ultrasonic transducer mounts and the test piece and this represents an improvement on previous equipments. Two ultrasonic transducers (2a, 2b) are mounted on each prism shaped block (4, 4A) so that one (2a) faces the interface with the test piece directly and the other obliquely. Mounting blocks are of different alternative shapes. Two or four such devices can be placed in an array on either side of a welded seam or joint (3) in a test piece and ultrasonic signals transmitted and their reflections picked up by particular transducers according to the orientation of any faults (7a, 7b) in the welded seam.

IPC: G06G1/00
Filed: 1970-07-18
Abstract: A gray wedge (3) and test copying paper (7) is covered with a rectangular board (11) on the entire surface of the copying paper. An exposure slit (12) which has blue (13) and yellow (14) filters are placed diagonally to each other.

The test paper is fully exposed at one end with blue light and other end with yellow light such that it is exposed in between with gradually varying blue and yellow colour bands. Exposed copying paper is then developed and measured with a sensitometer such that points measuring 0.2D are marked and added together and similarly those measuring 1.7D are added, thus having two measurements of equal density. Values of exposure time for colour bands are printed on a slide rule which has five scales-contrasts in terms of densities, total exposure time, maximum thickness of copying paper, percentage values of density.

Title: Anastigmatic deflection system for electron beams - has stigmator, with electron lens system and curved magnet with eight poles
IPC: H01J37/147
Filed: 1972-04-28
Abstract: The anastigmatic magnetic electron-deflection system consists of an eight-pole stigmator (1) in line with a circular electron lens (2).

Filed: 1995-02-27
Granted: 2004-07-28
Abstract: A method and apparatus for a two speed strap take up usable in a strapping machine. The two speed strap take up apparatus generally comprises a high speed roller assembly (20) driven by a high speed drive shaft (28), a low speed roller assembly (40) driven by a low speed drive shaft (48), a shaft rotation reduction assembly (56) interconnecting the high speed drive shaft (28) and the low speed drive shaft (48), and a roller clutch assembly (220) inter-connecting the shaft rotation reduction assembly (56) and the low speed drive shaft (48). An input clutch assembly (250) may inter-connect the high speed drive shaft (28) and an input drive means. In operation, a strap (12) is disposed between and frictionally engaged by a high speed roller (22) of the high speed roller assembly (20) and a low speed roller (42) of the low speed roller assembly (40). The low speed roller (42) is then driven in rotation by the high speed roller (22). When a first tension is applied to the strap (12), the high speed roller (22) slips relative to the high speed drive shaft (28) until the roller clutch (220) inter-connecting the shaft rotation reduction assembly (56) and the low speed drive shaft (48) engages and rotates the low speed drive shaft (48) at a reduced rotation rate relative to the rotation rate of the high speed drive shaft (28). The strap (12) is now driven by both rollers (22, 42) at the reduced rotation rate as the high speed roller (22) slips relative to the high speed drive shaft (28). When a second tension, greater than the first tension, is applied to the strap (12), the low speed roller (42) slips relative to the low speed drive shaft (48) at which time the strapping machine may perform additional functions on the strap (12) such as securing it around a package. <IMAGE>

Abstract: The invention relates to a method for automatically controlling the crusher clearance, determining the granular size, of a crushing machine which has a first circulating crushing tool 2-4 and at least one further crushing tool 5,7 assigned to the latter. The invention relates in particular to a method for operating an impact mill in which, in order to avoid substantial changes to the granular size of the crushed material, the impact mechanism 5,7 is moved when the impact mill is idling by means of a drive 10,11 up to the first contact with the impact strips 4 on the rotor 2 and, after identifying the resulting noises by means of a microphone 18, the movement is reversed until the previously specified crusher clearance is reached. According to the invention, a filter circuit is provided which makes the noises resulting from the contact of the crushing tools 4,5,7 recognisable for a computer which permits the steps necessary for the control to proceed according to a predetermined programme.

Abstract: A encapsulated stent device for implantation within the vascular system includes a balloon of a balloon catheter formed around and adhered to a wire-like stent so that the outer surface of the device is more regular for delivery through the vascular system without an exterior sheath. The encapsulation securely anchors the stent to the balloon and maintains a low profile for negotiation of tortuous and narrowed vessels. Encapsulation requires placement of the stent over the balloon, placement of a sheath over the stent on the balloon, heating and preferably pressurization of the balloon to cause it to expand around the stent within the sheath, and cooling while preferably maintaining pressure to cause the balloon to adhere to the stent and to set the shape of the expanded balloon. Retainers may be placed at the distal and/or proximal ends of the stent during the encapsulation process, or the balloon material may expand to form retainers. The balloon defines at least three folded wings for symmetrical expansion of the stent, and one or more connected or non-connected stents may be encapsulated depending upon the area to be treated.
