Title: Patient sling attachment means
Inventor: DALE G
IPC: A61G7/10
Filed: 2008-11-20
Abstract: A patient sling attachment means comprising a body 2, spreader bar attachment opening and lock bolt retention means 9. A spreader bar pin 13 with a head 11 is loaded via loading opening 6 and moved to the operating position 3, through restriction 4. The pin head 11 and restriction 4 prevent movement of the pin 13 to any position other than the loading opening 6. The lock bolt retention means comprises a lock bolt 8 and a finger grip 10. When pushed down, the lock bolt 8 blocks the exit of the pin 13 along the spreader bar attachment opening. The body 2 may also comprise a lift tape 7 for attachment of a sling to the device. The lock bolt 8 may be able to move freely vertically, always returning to the locked position. Alternatively, the lock bolt 8 may be spring loaded into the locked position or may be moved against a restraining force.

Title: Backside reflection optical display
Inventor: OSTRAND DANIEL K VAN
IPC: G02B5/02
Filed: 2007-09-21
Abstract: The disclosure generally involves an optical (perhaps flat panel) display (100) utilizing backside reflection for time-multiplexed optical shuttering. One display comprises a side-illuminated light guide (200) associated with conditions for total internal reflection. A first surface (202) of the light guide (200) is elastomeric. Disposed against this elastomeric surface is an active layer (300) that selectively deforms the elastomeric surface (202) in locations that can correspond to display pixels (120). This resulting change in the geometry of the elastomeric surface can be sufficient to defeat the conditions for total internal reflection. When appropriate, light is reflected by the particular deformation and is ejected from another surface of the light guide (200). In this case, each location that allows light to exit could represent an activated display pixel (120). In certain situations, color flat panel displays of varying sizes may further implement field sequential color and time-multiplexed optical shuttering.

Title: Demodulator
IPC: H03K9/04
Filed: 1965-03-09
Abstract: 1,066,922. Data transmission; automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES Inc. March 9, 1965 [March 18, 1964; June 5, 1964], No. 10001/65. Headings H4P and H4K.  The receiver in a system in which data is transmitted by carrier phase shift, N.R.Z. invert coding being employed, comprises a lowpass filter, which smoothes the received signal at the phase reversal points; and differentiating means to derive transition pulses from the filter output. The pulses pass to an integrating circuit which gives an output only when adjacent pulses are separated by more than a half cycle of the carrier, thereby indicating 1 bits, and also to means fed by the integrator, which gives an output indicating a 0 bit whenever there is no 1 bit from the integrator. The binary data thus produced passes to a shift register under the control of clock pulses derived from the received signals. The receiver forms part of a transceiver, there being means for preventing transmission during reception, and vice versa. The shift register is used at the transmitter input and at the receiver output. A telephone switching control system as described in Specification 1,066,921 is described for use in association with such transceivers.

Abstract: 1507471 Counting apparatus F HOFFMANN-LA ROCHE & CO AG 11 March 1975 [21 March 1974] 10167/75 Heading G4D In order to count objects, such as tablets, formed in a die, means is provided which senses the objects formed in the die just before they are ejected from it, a counter counting the objects sensed and controlling a gated dispensing arrangement to determine the destination of the objects. The tablets may be sensed as they move out of the die by an optical device which receives light reflected by the tablets (Figs. 5A, 5B, not shown). Accuracy is ensured by an air purge which blows away excess dust from the sensing area. Alternatives suggested are a fluidic sensor in which a stream of air, replaces the light beam and is "reflected" by the tablet, or a strain gauge which senses the forces in the die. The count may be predetermined and the gate (Fig. 6A, not shown) will switch the flow of tablets from one outlet to the other each time the predetermined count is reached.

Title: Improvements in and relating to methods of hydrolyzing dimethyldihalogenosilanes
IPC: C08G77/00
Filed: 1945-04-25
Abstract: Dimethyldihalogenosilanes are hydrolysed by gently flowing them on the surface of a gently swirling hydrolysis medium consisting of an aqueous solution of a salt of metal from the first or second group of the periodic table.  The product is a dimethylsilicone containing a higher proportion of high molecular weight polymers than usual. Suitable salts are sodium chloride, sodium carbonate, sodium sulphate, calcium nitrate, zinc chloride, copper sulphate, potassium carbonate and magnesium sulphate.  The hydrolysis medium should have a specific gravity of at least 1.1.  The solution may be gently swirled by means of a propeller sunk deeply therein.  In the example, sodium carbonate is used for the hydrolysis and the addition of the dimethyldichlorosilane is stopped when the solution becomes acid. The products are particularly suitable for the preparation of elastomers by the methods described in Specifications 592,018 and 594,481.

Title: An improved grading and weighing machine
IPC: B07C5/22
Filed: 1929-04-05
Abstract: 335,951. Hiscock, E. J., and Woodroffe, A. E. April 5, 1929. Sorting by weighing.-In apparatus for sorting eggs, packages of butter or other articles by weight into a number of predetermined grades, reciprocating feeding devices are provided for traversing a number of the articles at spaced intervals apart, simultaneously across a series of weighing devices each responsive to a different weight and each, when operated, serving to discharge articles to separate conveying and collecting means. In Fig. 1 is shown a machine for sorting eggs into four grades. The eggs are fed by hand to inclined guide ways 1, 2 and are admitted singly to a pair of troughs 5, 6 by stops 3, 4 intermittently raised by a cam. In the bottom of each trough are four apertures three of which are filled by scale platforms 30 arranged to descend and tip under various loads. A movable carriage 15, Fig. 3, is supported on the sides of each trough and is reciprocated by an inclined plate 47, Fig. 1, driven from the motor 14. Pivoted to the carriage are four rakes 20 coupled by a system of links as shown so that as the carriage is reciprocated, a pawl 24 comes into contact with a stationary plate 27 and raises and lowers the rakes so as to advance the eggs intermittently from the feed guides 1, 2 to the weighing platforms. The heaviest eggs are tilted off the first weighing platform and fall on to a belt conveyer 11 delivering to the first collecting receptacle 12. Lighter eggs are advanced by the rakes 20 to the succeeding weighing platforms and if not selected thereby are finally deposited through the fourth aperture in the trough and carried by a corresponding conveyer to the last of the collecting receptacles 12. Devices 42 count the eggs as they pass vane wheels 43. In a modified machine more suitable for grading packages of butter or like substances into three grades, correct, over and under weight, the rake-carrying carriages are reciprocated by cranks, and the balance beams contain a rolling ball to assist tipping. To prevent premature tipping of the scale pan a cam on the reciprocating carriage depresses a rack and causes a support temporarily to engage the scale pan until the packet is about to be moved on to the scale pan by the next reciprocation of the carriage.
