Title: Determining and marking apparatus and method for use in optometry and ophthalmology
Inventor: MARSHALL FORREST A
IPC: A61B3/02
Filed: 1991-01-18
Granted: 1993-11-11
Abstract: An apparatus and method for subjectively determining the proper positioning of progressive power or other corrective lenses are disclosed. The apparatus includes a target such as a small fiber optic or other light source and one or more marking rods which may be activated by the patient. While wearing pre-fitted frames and fixating on a remote target, the patient places the light source against or immediately adjacent the exterior surface of the simulated or other lens within either of the frames and positions the light so that it is centered in his or her line of sight. Once the light is centered the patient activates the marking rod which contacts, and marks, the exterior surface of the lens. Because the light source and marking rod or rods are designed to obstruct very little of the patient's vision, his or her peripheral vision remains intact during the process, thereby allowing binocular fusion to occur and avoiding introduction of phoria errors into the positioning process.

Abstract: A fastener tool (20) has a housing (22) in which is mounted a universal motor (24) to be continuously operated during operation of the tool. A gear (72) driven by the motor (24) is a rotary driven member. A drive pin (80) is carried by the gear (72) to rotate therewith and is free to be shifted axially relative the gear (72). A drive bar (76) is mounted in the housing (22) to drive fasteners (46). The drive pin (80) is connectable to the drive bar (76) to produce a power stroke and a return stroke. An interrupt mechanism (78) is operative to prevent successive power strokes and includes the drive pin (80); it acts to disconnect the drive pin (80) from the drive bar (76). Also the interrupt mechanism (78) controls the connection of the drive pin (80) and drive bar (76). The maximum number of power strokes are one-half the number of rotary cycles of the rotary driven member.The interrupt mechanism (78) includes a linkage (90) for sensing workpiece engagement and operator actuation of the tool, each of which are required to produce a single power stroke.The interrupt mechanism (78) may also include a track (84) and shifter (86) to axially shift the drive pin (80).The drive bar (76) has a slot (120) which in a start position is aligned to receive or release the pin (80) during a predetermined 45° arc of gear rotation.

Title: A method in the manufacture of sulphuric acid from gases generated in discontinuous processes
Inventor: PETERSSON S A
IPC: C01B17/76
Filed: 1982-10-22
Granted: 1986-08-14
Abstract: Method of utilizing process gas containing sulphur dioxide obtained from discontinuous processes, in the manufacture of sulphuric acid in a contact plant. When practicing the method according to the invention, all of the process gas, or a predetermined amount thereof, is withdrawn from the process during process operational periods, in which gas containing sulphur dioxide is generated, and the sulphur dioxide contained by the withdrawn gas is at least partially separated therefrom to form a liquid phase containing the amount of sulphur dioxide separated. The gas partially freed from sulphur dioxide, together with any non-withdrawn process gas, is passed to the contact plant for manufacturing sulphuric acid. Stored absorption liquid is utilized during those periods in which no process gases are produced or passed to the contact plant or in which the process gases contain insufficient sulphur dioxide. Sulphur dioxide is stripped from the liquid phase with the aid of a carrier gas, and the carrier gas, together with the stripped sulphur dioxide, is passed to the contact plant. This enables a required amount of gas and sulphur dioxide to be constantly supplied to the contact plant, even during those periods when the discontinuous process does not produce a sulphur-dioxide-containing gas or produce a gas having an insufficiently high sulphur-dioxide amount.

Title: Frequency demodulator with two parallel paths - has paths supplied with modulated input frequency and reference frequency
IPC: H03D13/00
Filed: 1970-02-07
Abstract: The frequency demodulator hs two parallel paths for sawtooth waveforms conversion and comparison, each path being supplied with the modulated input frequency in similar phase and a reference frequency in opposed phase. Each parallel path is alternately connected to the output via a phase responsive switch controlled by the phase-shifted reference frequency. Preferably each path contains a multivibrator connected via a low-pass filter and a capacitor to a difference circuit. The demodulation circuit enables to use a phase meter, as the sawtooth output voltage is fed to the differentiating circuit whose series connected circuit suppresses the voltage peaks of the demodulation product.

Title: Movable multistrand cable circuit modules - has twisted insulated wires soldered at ends forming looms with los HF interference
IPC: H01R35/02
Filed: 1970-10-21
Abstract: The multistrand movable power supply lines are used to interconnect printed circuits, particularly in instruments with a large number of modules individually inter-changeable where it is necessary to reduce high frequency inter-frequency along the interconnecting lines. The individually insulated wires (1a, 2a, 3a, 4a, 5a) of each strand are connected in parallel. They are used to form looms (1, 2, 3, 4, 5) of closely knitted individual wires.

Title: Plastic sailing boat hull with rigid bottom board - providing structural strength enabling hull to be thin
IPC: B63B3/38
Filed: 1971-03-02
Abstract: A sailing boat of plastics comprises an outer, ribless hull and an inner bottom board, attached to the inner face of the hull by a surrounding stringer flange and with foam filling between bottom board and hull. The bottom board is a principal structural member, accepting the major loads acting on the hull. It is preferably located approx. at the water line. In one variant, it is formed as a sandwich board, comprising two outer plates, and a foam centre. This bottom board may be either flat or slope slightly downwards away from the centre line towards the sides, in particular with a central stiffening upstanding bulge and with gutters or scuppers along both sides. By making the bottom board the principal structural member for the hull, it is possible for the outer shell of the hull to be made as a simple laminated sheet; thus the simplest form of construction is utilised in the part of the structure requiring the greatest curvature and care in manufacture, while the stronger member is incorporated as the relatively flat bottom board.
