Title: Chitin and egg-shell prepns for cicatrising wounds
IPC: A61L15/28
Filed: 1969-03-11
Abstract: Compositions for facilitating the healing of wound: (i) Finely divided chitin, partially depolymerized chitin, a deriv. of chitin, or a mixture of these. (ii) Finely divided egg-shells free of membrane, or a mixture of finely divided egg-shells and finely divided egg-shell membranes.

IPC: G01S7/481
Filed: 1972-01-18
Abstract: 1374295 Optical ranging HEWLETTPACKARD CO 23 Dec 1971 [18 Jan 1971] 59953/71 Heading H4D In an optical range detecting arrangement, Fig. 1, in which a light emitting diode (LED) 10 is driven to emit a modulated light beam or a pulse, the phase of the beam or timing of the pulse will vary across the radiating surface 28 of the diode such that a phase comparison at 26 between the modulations of the driver 12 and that of the received reflected beams gives a range indication varying in dependance on where the reflector 22 is in the cross-section of the beam, One way of overcoming this source of range uncertainty is to spread the light emitted from any point of surface 28 over the whole crosssection of the beam. This is done by a light beam homogenizer 34, Fig. 2, e.g., consisting of a glass light prism Fig. 3, exactly covering the diode 10 and internally reflecting and dispersing the light emitted by the diode surface 28. The light emitting surface 40 of the prism may be frosted. A highly polished hole in a metal sheet may be used for the homogenizer.

Title: Steam reforming of hydrocarbons - using surfaces of reactor heating tubes as catalyst
IPC: C01B3/38
Filed: 1973-01-26
Abstract: In the catalyst reforming of hydrocarbons with steam and CO2 mixts., with the necessary heat for the endothermic reaction being supplied from outside through a sepg. wall, the heat is transmitted to the catalyst entirely by conduction through solids. Pref. the side of the wall facing the reaction space is composed of catalytic material, the wall consisting of a layer of pressure-resisting material with a thin adherent layer of catalyst. The temp. gradient between wall and catalyst which exists in the usual process, where heat is transmitted by the reaction gases, is eliminated.

Title: Measurement of circumference of spectacle lenses - involves rotating lens while roller tracks edge
IPC: G01B3/12
Filed: 1973-07-23
Abstract: The circumference of a spectacle lens is measured by placing the lens between two spring loaded soft pads (34), contacting its edge with graduated dru m (58) and rotating the lens through exactly 360 deg. The revolution is defined by the driving handle (37) which is arranged to closely lock into a groove (44) on the frame. The drum is spring-loaded to lie either against a lens or against the collar (23). A spectacle frame is mounted between pillars with grooves, two pillars underneath (3, 4) and one above (11) each pillar being adjustable in height above the base. A button on the cranked end of an axle (21) is rotated around inside the frame and the drum is said to indicate the perimeter. The axle (21) is slidable axially to allow for a non-planar frame.

Title: Mechanical torque detector - torsion bar and pressure sensor to measure applied torque, no rotating joint
IPC: G01L3/04
Filed: 1974-02-20
Abstract: A torque detector has a case (1) which is rigid in torsion. One end (1a) of the case (1) may be connected to a machine drive. It has a torsion bar (5). The drive end (1a) of the case (1) is fixed to one end of the torsion bar (5). The detector also has two other elements (8, 15), one (8) of these elements is fixed to the other end of the torsion bar (5) and the other element (15) is fixed to the other end of the case (1). Each of these elements (8, 15) has ramps (17, 18) and these ramps are separated by balls (19). When a torque is applied to the detector and is transmitted by the torsion bar (5), the bar is subjected to a torsional deflection proportional to the applied torque. The element (15) attached to one end of the bar (5) rotates with respect to the element (8) attached to one end of the case (1). Because of the ramps (17, 18) and the balls (19) one element (15) moves axially and this movement is detected by a pressure sensor.

Title: Capacitive proximity alarm - has plug varying resonant frequency of oscillator reference and control coils
IPC: H03K17/16
Filed: 1974-03-05
Abstract: The proximity alarm, particularly designed to operate when approached by a person or by a hand, is based on the principle of change in capacity of an oscillatory circuit normally not oscillating but producing an oscillatory output and energising a relay when the capacitance changes. Protection against parasitic effects is obtained by offsetting the resonant frequencies of the tuned circuits making up the base to collector feedback transformer. The base winding is connected to the proximity detector plate and wound side by side with the collector winding on the same transformer, tuning beng affected by an adjustable ferrite slug extending entirely through one winding and partly into the other.

Title: Membrane filtration plant - in which press energy is recovered by hydraulic motor in outflow pipework for retentate
Inventor: HALD THERKEL
IPC: B01D37/04
Filed: 1975-08-13
Abstract: In a membrane filtration plant a membrane filter is connected into a piping system whose upstream side delivers the medium to be filtered to the filter and whose downstream side removes from the filter partly "retentate" (medium which does not pass through the filter) and partly "permeate" (which has passed through the filter). According to the claim the upstream pipework incorporates a feed pump for the medium to be filtered, which has, as well as an independent power source, such as an electric motor, a hydraulic motor which is connected into the downstream side pipework so that the pump can be partly driven by retentate from the filter. The relative amts. of power derived from the independent power source and the hydraulic pump are controlled by signals from a pressure sensor connected into the working side of the pipework for the retentate. The filtration plant is used for the desalination of sea water, concn. of protein in milk etc.
