Title: Carbamates of bisphenols
Inventor: NIKAWITZ EDWARD J
IPC: A61K8/00
Filed: 1969-06-06
Abstract: 1,216,156. Bis-phenol carbamates. L. GIVAUDAN & CIE SOC. ANON. 6 June, 1969 [11 June, 1968], No. 28665/69. Heading C2C. [Also in Divisions A5 and C5] The invention comprises compounds of the Formula I wherein R represents a lower alkyl C 1-5  or alkenyl C 2-5  radical, X is a halogen atom e.g. chlorine and n is 2 or 3 with the proviso that when n is 2 R is a methyl radical. They are prepared by reacting the appropriate bis-phenol with the isocyanate of formula RNCO. The compounds of Formula I may be incorporated in soap and cosmetic compositions as bacteriostatic agents.

Title: A machine for applying floor polish to floors
IPC: A47L11/08
Filed: 1945-10-31
Abstract: 604,158. Floor-polishing brush-machines. BROWN, G. R., and SCHRONEN, J. H. Oct. 31, 1945, Nos. 28853 and 28854. Convention dates, Nov. 29, 1944, and June 23, 1945. [Classes 19 and 138 (i)] A machine for applying polish to floors comprises a frame or chassis in which are mounted a rotatable floorengaging cylindrical brush, a polish container and at least one rotatable roller in engaging contact with said brush for transferring and applying the polish contained by the container to the cylindrical brush which in turn applies it to the floor as the machine is pushed across the floor, which action causes rotation of the brush and the roller or rollers. In one form, Fig. 2, the machine comprises a chassis 1 carrying a driving roller 2 having floor-engaging treads 3, a polish-applying brush 6, an intermediate roller 11 mounted on a shaft 15 in slotted bearing plates 12 fixed to the chassis, the roller being held in contact with the driving roller and brush by means of springs 13 and a polish-container 20. The driving roller 2 receives polish 22 from the container 20, the polish being pressed on to the roller by means of a plate 21 having adjustable spring control means comprising a plunger 25 and spring 26 housed in a cylinder 24 and operated by a control screw 28. The machine is provided with a handle 31, a cover 18 having a hinged portion 19 giving access to the polish container and brushes 16 and 17. In operation, the intermediate roller is caused to rotate by frictional contact with the brush 6 and the driving roller 2 and the polish adhering to the driving roller is transferred to the intermediate roller which transfers the polish to the brush and thence to the floor. In another form (Figs. 5 and 7), a cover casing 40, serving as the chassis, carries a polish applying brush 41, a polish-transferring roller 48 and a polish container 47. The brush 41, mounted on trunnion pins 45, has floor-engaging flanges 42 at each end and is provided at one end with a gear-wheel 52 which meshes with a pinion 53 secured to the end of the roller 48 so that when the machine is pushed across the floor, rotation of the brush causes rotation of the roller. The polish-container 47, which encloses part of the roller 48, is provided with a weighted member 54 hinged to a side of the container and adapted to press the polish 56 on to the roller 48. Two brush covers 57 are provided interiorly of the chassis 40, whereby the polish received from the roller is spread over the brush in a thin layer for transfer to the floor.

Title: Data demodulator employing multiple correlations and filters
IPC: H04L27/233
Filed: 1972-06-20
Abstract: 1401822 Digital transmission; PSK demodulators SANDERS ASSOCIATES Inc 20 June 1972 [1 July 1971] 28854/72 Heading H4P A demodulator for a modulated carrier signal, particularly P.S.K. and F.S.K. has a correlation network which operates on the identity and non identity of a modulated signal with at least two delayed replicas of the preceding band to produce first and second correlation signals passed through digital filters in the form of reversible counters, outputs from which are mutually compared in sign and magnitude to reproduce the original information. A sync. circuit responsive to input signals provides clock pulses substantially centred in each band. The correlation network includes exclusive OR gates; which control direction of the counters which are enabled during an integrate period at the end of which the content is dumped into a store, e.g shift register which is sampled. In the embodiment disclosed, a 4 phase PSK signal through delay equalization BP filter 11 and amplifier/limiter 12 is applied to a delay element 13, possibly a shift register clocked at a rate faster than the baud rate having a plurality of taps 13-1, 13-4 giving a total delay of 1 baud +#/4 rad. An exclusive OR 14-1 correlates undelayed signal B with delayed signal C to provide D, giving an output having one value on identity and another on non identity. Tap 13-3 also provides a replica of the previous baud, delayed 1 baud-#/4, B, F feeding another exclusive OR 14-2 providing signal G. To synchronize the demodulator exclusive OR 14-3 correlates B with itself delayed 1/3 rd baud to provide a signal K from which carrier frequency components have been eliminated. G, D signals are filtered by L.P filters 161, 162 which may be reversible counters controlled by correlation signals D, G. At the determination of each integrating period, determined by clock output from 15, counter contents are humped into shift registers 17-1, 17-2, forming part of magnitude and sign counter 17, via gates 17-3, 17-4. If 16-1 is greater than 16-2, the vector is- #/4 if the sign is negative or 3#/4 if positive. Shift register outputs, through 2's complementers 17-7, 17-8, are compared bit by bit at 17-9 to determine the larger giving an output M, M which with sign information are fed to decoder 17-10 comprising NAND gates (17- 101-5, Fig. 5, not shown) which inserts appropriate bit pair into shift register 18 which pairs are serially shifted out to a receiving device.

Abstract: 859,010. Television pick-up tubes. ENGLISH ELECTRIC VALVE CO. Ltd. July 27, 1959 [Sept. 9, 1958 ; Oct. 15, 1958], Nos. 28950/58 and 32908/58. Class 39(1). The optical image to be televised falls on a photoconductive layer of low specific resistivity backed by a transparent conductive electrode and connected thereto at a plurality of'a spaced area, a plurality of photoemissive elements being positioned on the other side of the photoconductive layer and arranged to be uniformly illuminated by light, the elements being connected to the photoconductive layer at areas none of which is opposite to the areas where that layer is connected to the electrode so as to give long current paths extending mainly in the plane of the layer. As shown in Fig. 2, light from the object passes through the transparent conductive electrode A2 on to the photoconductive layer A3 e.g. of cadmium selenide or sulphide or of lead telluride and the resulting changes in conductivity of that layer control the photoemission from a photoemissive layer A5 flooded by a source of light 13. The corresponding electron image passes through an equipotential grid 15 maintained at a fixed potential and falls on a secondaryemissive target 16 of high specific resistivity, secondary electrons from which are collected by grid 17 and which is scanned by an electron beam 8 to produce the picture signals at 5. Alternatively the photoconductive layer A3, Fig. 1, of the second Provisional Specification is covered by an Insulating layer A4 through which protrudes at spaced intervals an opaque metal layer A5 penetrated at A6 by photoemissive material. The conductive electrode A2 may be as shown or constituted by a conducting layer separated from the photoconductive layer A3 by discrete areas of insulating material. The first Provisional Specification discloses a photoconductive layer whose elemental areas are connected to a photoemissive layer by metal connectors extending through the intervening glass supporting.

Title: Improvements in or relating to treatment of cotton linters
IPC: C08B11/04
Filed: 1956-09-07
Abstract: In the purification of cotton linters by treatment with aqueous caustic soda at an elevated temperature and pressure, the tendency of the linters to become less reactive is reduced by etherifying the linters, but only to such an extent that the etherified linters remain both alkali- and water-insoluble while retaining the fibrous structure of the unetherified linters, the etherification being effected prior to any substantial increase in the crystallinity of the linters due to the action of aqueous caustic soda.  Ether substituents which may be introduced include hydroxyethyl, hydroxypropyl, hydroxybutyl, carboxymethyl, carboxyethyl, sulphoalkyl and cyanoalkyl.  The etherified linters may be bleached, e.g. with chlorine, hypochlorite, chlorine dioxide, peroxide or permanganate, after the treatment with aqueous caustic soda.  Comparative experimental results are given.
