IPC: G02F1/017
Filed: 1989-02-04
Abstract: A method of modulating an optical beam (1) and apparatus for use in such a method are described. An etalon structure (2) is provided which has an absorption edge in the vicinity of the wavelength of the optical beam (1) and which comprises material of a smaller band gap, for example gallium arsenide, sandwiched between layers of material of a larger band gap, for example aluminium gallium arsenide, so that the smaller band gap material forms a quantum size effect confinement region for electrons and holes. The smaller band gap material may consist of layers (4) separated by barrier layers (3) of the larger band gap material so that the layers (4) form quantum wells. The optical beam (1) is directed through quantum size effect confinement region of the etalon structure (2) and a polarised control optical beam (5) is directed at the etalon structure (2) perpendicular to a direction of quantum size effect confinement of the etalon structure (2), thereby causing the optical beam (1) to be modulated by the control optical beam (5).

Abstract: A bulk material container (10) in which is disposed an inflatable vessel (35). Also disposed in the container (10) above the inflatable vessel (35) is a compressible vessel (40) containing the product to be disposed. Between the inflatable vessel (35) and the compressible vessel (40) is disposed a generally rigid disc (36). A source of air under pressure disposed exteriorly of the container (10) communicates with the inflatable vessel (35). As air under pressure is discharged into the inflatable vessel (35), the inflatable vessel (35) expands to lift the disc (36) vertically within the container (10). This action causes the compressible vessel (40) to be compressed for dispensing the product from the compressible vessel (40).

Abstract: An operable syringe assembly (20) includes a barrel (21) having an inside surface (22) describing a chamber (23) for retaining fluid, an open barrel end (25), and a distal barrel end (27) having a passageway (28) therethrough in fluid communication with the chamber (23). A plunger rod (33) includes an elongate body portion (34), a proximal end (37) and a distal end (38) with a stopper (39) positioned at the distal end (38). The stopper (39) slidably positioned in fluid-tight engagement in the barrel (21). A locking element (42) is positioned in the barrel (21) between the plunger rod (33) and the inside surface (22) of the barrel (21). Locking element (42) includes a proximally and outwardly facing locking barb (46), a distally and inwardly facing resisting edge (50) and an inwardly facing driving edge (52). Driving edge (52) interacts with the plunger rod (33) to move the locking element (42) along the barrel (21) as the stopper (39) is advanced distally along the barrel (21). The resisting edge (50) and the barb (46) prevent proximal motion of the plunger rod (33) with respect to the barrel (21) after the initial motion of the stopper (39) to expel fluid through the passageway (28) wherein proximal motion of the plunger rod (33) with respect to the barrel (21) causes the resisting edge (50) to engage the plunger rod (33) causing the locking element (42) to move in a proximal direction wherein the locking barb (46) engages the inside surface (22) of the barrel (21) to prevent further proximal movement of the plunger rod (33) with respect to the barrel (21). A barrier element (65) is provided on the plunger rod (33) for limiting the delivery volume of the syringe assembly (20) by establishing the maximum proximal position of the locking element (42) with respect to the plunger rod (33).

Abstract: The invention relates to a digital transmission system for the simultaneous transmission of a plurality of binary digital signals via separate conductor pairs. In addition to a threshold detector (SD) known per se, a noise value predictor (1) is used. Its sampling values are derived from the differential signal (ri) obtained from the Nyquist-equalised signal (ki-1) and the detected signal (vi). This considerably increases immunity to cross-talk interference.

Abstract: A process 10 for producing calcium carbide includes operating a furnace 12 of the kind described by continuously feeding calcium oxide and carbon and/or carbon containing material as feed materials into the furnace chamber, subjecting the feed materials or solid burden in the chamber to a plasma torch generated between the plasma burner and the counter electrode, withdrawing calcium carbide intermittently or continuously by means of the calcium carbide withdrawal means, and withdrawing off gas continuously through the gas withdrawal means. Lime hydrate (Ca(OH) 2 ) material in agglomerated form passes through an elongate dryer 50, while the off gas passes through the dryer countercurrently to the lime hydrate material. The velocity of the gas is sufficient to entrain therein solid particles below a predetermined size and which are present in the lime hydrate material, thereby to pretreat the lime hydrate material by classifying it, and drying and calcining it to form calcium oxide (CaO) material.

Abstract: In an arrangement for coding multi-element signals such as used in speech or image processing, a plurality of N element reference signals representable in a prescribed vector space are stored (101). An N element input signal representable in the prescribed vector space is received (103) and one of the reference signals is selected to represent the input signal. A set of signals each representative of the projection of one of the reference signals on a predetermined orientation in the prescribed vector space and a signal representative of the projection of the input signal on the predetermined orientation are formed. The reference signals are arranged according to their projections on the predetermined orientation. Candidates for the best matching reference signal are selected (135,140) according to the differences between their projections on the prescribed orientation and the projection of the input signal on the prescribed orientation an projection difference signals are utilized to determine the reference signal closest to the input signal in the prescribed vector space.

Heel end centralising means (390) and toe end centralising means (822′) are also provided. More particularly toe centralising fingers (822′) are provided with collars (882) mounted for equidistant heightwise movement to engage the lasting marginal portions of the shoe in the forepart region and thus level the shoe bottom about the heel-to-toe line determined by the holddown and toe abutment. In addition the last pin can rock about a lengthwise axis and is locked in "rocked" position by a wedging system (862, 866). When the shoe has been properly located the last pin is urged to pivot toewardly thus to cause the last pin to "bind" on the last pin hole formed in the last and, by the counter-force supplied by the toe support (792), the shoe is thus securely clamped on the last pin and toe support.
