Title: Radar doppler intruder detector
IPC: G01S7/00
Filed: 1981-02-11
Abstract: A portable security unit operating by radar has an antenna 20 mounted at a predetermined distance above the ground which emits an FM CW signal having a carrier frequency in the range 1-2 GHz for example. Reflections from moving targets are sensed and processed with a signal at the transmitted frequency to obtain the second harmonic of the modulation frequency from which in turn the Doppler frequency component is extracted and its amplitude, which varies with range as a second order Bessel function, is measured. The second order Bessel component has a low amplitude for targets near to the unit, thereby minimizing false alarms from birds and the like. The amplitude of this component is also attenuated beyond a predetermined distance from the unit and this, in conjunction with attenuation caused by interference between direct and reflected transmitted waves which is arranged to occur beyond the same distance, prevents unwamted echoes from targets outside the desired range of the unit. <IMAGE>

Title: Process and Apparatus for Making Glass Surfaces Abrasion- Resistant and Article Produced Thereby
IPC: C23C16/04
Filed: 1981-02-16
Abstract: The present invention relates to improving the scratch and abrasion resistance of glass surfaces, and especially the exterior surfaces of glass containers such as bottles, jars, tumblers, stemware, and the like. The glass articles are exposed to a highly moisture reactive first constituent confined to the centre of the flow pattern and a less moisture reactive second constituent surrounding said first constituent. TiCl4 may form the first constituent with SnCl4 being the second constituent. The articles are then able to be overcoated at a lower temperature such as by organic materials to further improve their lubricity and durability. The subject process of providing a primary coating is markedly more economical than presently known processes.

Title: Fire retardant polymer resin
IPC: C08J5/24
Filed: 1981-03-26
Abstract: Method of forming a flame retardant polymer resin, comprising the steps of reacting a first aldehyde and first polyhydric phenol in the presence of a mineral acid in sufficient proportions to provide an acid-condensation reaction product in the form of a relatively low molecular weight, low viscosity liquid linear polymer having excess aldehyde functionality; mixing a second aldehyde and second phenol to provide a solution of said second phenol in said second aldehyde which solution contains said aldehyde in molar excess; adding to said reaction product a solid, organic, water soluble acid as a polymerization active catalyst; adding to said solution an inorganic Lewis acid polymerization initiation catalyst containing water of hydration; reacting said reaction product and solution in the presence of said catalysts to produce condensation polymerization thereof into said resin. In an alternative method the said solution of the second aldehyde and second phenol is replaced by a reaction product thereof. A foam may be produced by adding a foaming agent prior to completion of the reaction. Preferably the polyhydric phenol is resorcinol, the aldehyde is furfural or a mixture thereof with paraformaldehyde and the Lewis acid catalyst is boric acid or a complex thereof. The invention also relates to a method of forming a flame retardant polymer comprising mixing a polyhydric phenol with an aldehyde in a molar ratio of 0.5 to 1 and adding thereto an acid catalyst to produce condensation polymerization.

Title: Improvements in fluid-pressure operated servo-motor assemblies
IPC: B60T13/14
Filed: 1979-02-02
Abstract: In a servo-motor assembly for a vehicle braking system an effort is transmitted from a pedal-operated input member 6 to an output member 4 in axial alignment with the input member 6 through a movable wall in a housing 1, and a boost chamber 7 is defined between the members to which pressure fluid under the control of a valve 8 is admitted for application to the movable wall to augment the effort. So that the assembly can operate at higher pressures the effective diameter of the input member 6 is reduced by the provision of an additional chamber 85, sealed from the boost chamber 7, defined between the input member 6 and the output member 4, which has a cross-sectional area less than that of the input member 6 and is vented to a pressure substantially less than the fluid operating pressure. This overcomes the problem of reducing the effective diameter of the input member 6 to prevent increase of the reaction force on the input member 6, while avoiding the reduction in size of an input rod which transmits effort from the pedal to the input member 6, while avoiding the reduction in size of an input rod which transmits effort from the pedal to the input member 6. <IMAGE>

Title: Free Flowing Crystalline High Dextrose Bearing Product
IPC: C13B30/02
Filed: 1981-06-02
Abstract: A free flowing, handleable, crystalline, anhydrous high dextrose bearing product is prepared from a starch hydrolyzate. The starch hydrolyzate is first concentrated to a high dry substance level. It is then simultaneously crystallized and crushed by mixing while cooling. Seed material selected from any crystalline sugar, e.g. dextrose, may be added during this stage. The crushed crystalline product is then further cooled and milled to a reduced particle size. Screening can be used if necessary to obtain a specific particle size. The crushed and milled product is then conditioned in two stages. The first stage is drying in a fluidized bed to less than about 0.5% total moisture and the second stage is cooling to below about 35 DEG C. Handleability (non-caking qualities) and composition stability with respect to crystallinity and beta-anhydrous dextrose content of the high dextrose bearing product are excellent even after it has been stored in bags for long periods of time.

Patent GB-828222-A (GB)
Abstract: 828,222. Ticket-issuing machines. TICKET EQUIPMENT Ltd. Nov. 6, 1957 (Nov. 6, 19561, No. 33809/56. Class 106 (3). A ticket-issuing machine of the type having a printing drum and a fare-setting drum associated therewith in which the fare drum is capable of angular displacement relatively to the printing drum for the purpose of changing or setting a fare, has a dog clutch between the fare drum and the printing drum so that the two are normally interlocked and the fare drum is capable of axial displacement in order to disengage the dog clutch when it is desired to alter the fare setting. The machine is of the general type described in Specification 586,944 and has a casing comprising two parts A, B containing respectively the fare setting drum F and the printing drum P which are mounted on a spindle 1. A flanged housing 9 for a spring 2 is secured to the outer end plate of the drum F and has a spigot 10 to which a control knob K is fastened. The spring 2 acts between a collar 12 secured to the spindle 1 and the drum F to bias the latter inwards so that a toothed disc 5 fastened to the inner end plate of the drum F normally engages a correspondingly toothed disc 6 secured to a plate 7 carried by a boss on the inner end of the drum P which projects through the casing partition wall. To alter the fare setting the knob K is first pulled outwards so that the drum F moves to the left as shown, against the bias of the spring 2 and the toothed discs 5, 6 are disengaged; the knob is then rotated to turn the fare-setting drum F until the desired fare, which is marked on its periphery, appears at an inspection window. This movement is transmitted, by means described in Specification 586,944 to printing wheels in the drum P so that they are positioned to print the desired fare. The knob K is then released, allowing the discs 5, 6 to re-engage, and a handle H is rotated once whereby the drum P is rotated to print and issue a ticket and the drum F is rotated to actuate a totalizing device associated therewith. To prevent the printing drum from being rotated when the fare-setting drum is not engaged therewith a bar 13 having an arm 19 and a down turned end 14 is mounted above the fare setting drum. A screw 16 carried in the end 14 has an enlarged head which slides in an opening in a plate 18 which is secured to the casing part B by long bolts 21. The bar 13 is biased to the right by a spring 25 but when the drum F is disengaged from the drum P it acts upon the screw 16 so that the bar is moved against the bias of the spring 25 until the arm 19 enters a slot in the periphery of the plate 7, thereby locking the drum P against rotation. Specification 614,375 also is referred to.
