Filed: 1976-01-12
Abstract: 1511461 Doppler intruder-detector PITTWAY CORP 12 Jan 1976 [21 Jan 1975] 01008/76 Heading GIG [Also in Division G4] An intrusion detection system covering a plurality of separate zones comprises ultrasonic wave transmitting transducers for each zone, respective receivers for each zone, a master oscillator for driving all the transmitting transducers and to which all the receivers are coupled for producing individual Doppler signals indicative of moving objects in the respective zones, and indicators at a central location for selectively indicating each zone in which a moving object is located. In the Fig. 1 embodiment each zone is provided with several transmitting transducers 27 and receiving transducers 38. Receiving and signal processing circuits for two zones are contained in each of modules 21, 26. The system can be extended by adding further dual-zone modules. Master control 11 powers all the transmitting transducers and feeds a synchronizing signal to the modules for synchronous demodulation, within each module, of the receiving transducer signals. Each module, Fig. 2 (not shown) filters the demodulated signals for its two zones to extract desired Doppler frequencies and de-energizes a relay if the Doppler signal amplitude, integrated over a one second period, exceeds a threshold value. Respective alarms 42--45 are actuated by the relay de-energizations. Intrusion into any zone also actuates a general alarm 17 of audible or visual type locally, or remotely via a telephone line or other link. Provision is made for manual testing of the alarms.

Title: Method for preparing diboron tetrafluoride
IPC: C01B35/06
Filed: 1962-01-12
Abstract: B2F4 is prepared by the reaction between SF4 and BO or B2(OR)4, where R can be H, a saturated aliphatic hydrocarbon radical with or without one or more aromatic hydrocarbon substituents, or an aromatic hydrocarbon radical with or without one or more saturated aliphatic hydrocarbon substituents, below ambient temperature in a substantially anhydrous oxygen-free atmosphere; the B2F4 is recovered from the reaction mass; SOF2 is also produced in the reaction.  A number of B2(OR)4 compounds are exemplified, particularly tetrahydroxydiboron and tetraethoxydiboron.  The reaction may be performed at -100 DEG  to 0 DEG  C., and stoidicometric (\sB15%) amounts of reactants are used. After the reaction is complete, the reaction mass is warmed to the ambient temperature and the B2F4 recovered by fractional condensation.  B2F4 reacts with H2O to give HF.  When heated in a reducing atmosphere, it decomposes with the production of boron.  It reacts with compounds whose molecule contains more than one group that reacts with the fluorine atom to form polymers containing =B-B= groups.  It also reacts with unsaturated substances to form diboronic acid derivatives.

Title: Improvements in or relating to the propulsion of fluids by means of oscillating fan like elements
IPC: B63H1/36
Filed: 1921-01-10
Abstract: 157,381. Schieferstein, H. Feb. 15, 1919, [Convention date]. Fans.-In a rapidly oscillating mechanical system comprising an oscillating elastic plane or the like, the rate of oscillation of the driving element, e.g. crank, is made to correspond with the " natural " rate of vibration of the elastic plane either by " tuning " the plane by loading or otherwise or by adjusting the driving-power, the result being a maximum efficiency of propulsive effort on the air or other fluid medium in which the plane vibrates. The invention is applied to the propulsion of gases, to vacuum-cleaning, and to the propulsion of ships, vehicles, sledges, and aircraft. In the case of a vacuum cleaner, Fig. 4, the vibrating blade a is mounted in a nozzle-like casing g and carries on the edge opposite its pivot a brush f. In the case of ship propulsion, Fig. 6, the plane a may be horizontal as shown or vertical, and more than one may be employed. Fig. 9 shows the application to an aeroplane, two superposed vibrating planes a<1>, a<2> being employed. The edges of these planes are made as flexible and free from inertia as possible, e.,g. an elastic steel skeleton covered with fabric or formed by separate elastic laminµ. Further, the lateral ends have extensions of triangular form rounded at the apex and connected to the main plane by springs d, e, the aim being that the extensions shall have no pronounced " natural " oscillation. The planes may be made of elastic homogeneous material (steel, bronze, &c.) or of ribs covered with fabric, or may consist of several independent oscillating planes. Specifications 17033/90, [Class 114, Ships &c., Div. II], and 5092/00 are referred to.

Abstract: 264,535. I. G. Farbenindustrie Akt.- Ges. Jan. 18, 1926, [Convention date]. Hydrogen peroxide, concentrating and distilling.-Hydrogen peroxide solution is concentrated by atomizing it into a chamber or passing it down the inner surfaces of tubes or down a tower containing superposed domes or non-catalytic fillers such as balls of glass or porcelain in contact with a stream of air, oxygen, or other gases which do not react with the solution. The tubes or the tower are heated externally or by internal coils to about 70‹ F. or the stream of air &c. is heated to about 65‹ C. The operation is carried out under ordinary increased or reduced pressure. The air &c. before use may be freed from dust and moisture, and after use may be treated to remove moisture and used again. The solution may be raised to a concentration of about 50 per cent. If the treatment be continued, hydrogen peroxide vapours are evolved and by condensation, hydrogen peroxide solution free from inorganic constituents is obtained. This distillation may be carried out in a second tower or in the lower part of a single tower, a part of the current of air &c. being withdrawn at an intermediate position in the tower. The Specification as open to inspection under Sect. 91 (3) (a) describes also that the operation may be carried out by the use of reduced pressure only and that the gases may be replaced by vapours.
