Title: Laminated glass windows
IPC: B32B17/10
Filed: 1968-06-13
Abstract: 1,214,519. Laminated glass. PPG. INDUSTRIES Inc. 13 June, 1968 [14 June, 1967], No. 28057/68. Heading B5N. [Also in Divisions B1-B2 and C3] A laminated glass window comprises at least one solid glass sheet having bonded thereto an adherent transparent layer of a polyurethane derived from an organic polyisocyanate and an organic polyol, and containing from 0À01 to 3À0% by weight of a proton-containing antimony, arsenic or phosphorus compound. The polyurethane resins may be prepared (1) by reacting all the ingredients in a cell formed by the multiple layers of glass to be laminated, (ii) in a thermoplastic state by partial reaction of all the ingredients, the thermoplastic material being placed between glass plates and cured to a thermoset state by heating or (iii) by fully reacting the ingredients prior to their insertion between sheets of glass. The proton containing compound incorporated in the polyurethane is most suitably an active hydrogen-containing phosphorus compound, e.g. stearyl acid phosphate, a commercial fatty alcohol phosphate, octylphenyl acid phosphate, iso-octyl acid phosphate, methyl acid phosphate, butyl acid phosphate, amyl acid phosphate, lauryl acid phosphate, high monostearyl acid phosphate or oleyl acid phosphate. In an example laminates were formed from two sheets of glass by forming a casting cell of these sheets the outer edge of which was taped to form a liquid-tight casting cell with an opening across one edge only, various admixtures then being poured into the cell and cured by heating.
Patent GB-464052-A (GB)
Title: Compensating networks for electrical transmission circuits
IPC: H03F1/36
Filed: 1935-10-11
Abstract: 464,052. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and REID, D. G. Oct. 11, 1935, No. 28127. [Class 40 (v)] Comprises means for compensating distortion of phase and/or attenuation in a transmission circuit such as a transformer-coupled amplifier for television or telephone signals. In such an amplifier a phase lag is introduced and the distorted signals are applied to the input terminals 1, 2. The output voltage V2 at terminals 3, 4 is the sum of three components comprising (i) the input voltage V1, represented by OA<1>, Fig. 1b; (ii) the voltage A<1>B<11> (or at a higher frequency A<1>C<11>) induced in the transformer secondary L<1>1, which is in quadrature with V1 and is proportional to the frequency R1 being great in comparison with the impedance of L1 ; and (iii) the voltage B<11>B<1> or C<11>C<1> induced in L<1>2, which is in opposition to V1 and is proportional to the square of the frequency, R2 being great in comparison with the impedance of L<1>2. The circuit is so dimensioned, in accordance with calculations indicated in the Specification, that if OA<1> represents an undistorted input the vector OB<1> is inverse to the vector representing the input that is to be corrected. Thus, when the distorted input, instead of V1, is applied at terminals 1, 2, the product of the vectors, representing the final output, is free from phase-distortion and is in phase with OA<1>. In a modification, Fig. 3 (not shown), (1) the coil L<1>1, instead of being connected directly to the terminal 1, is tapped off a potentiometer shunted across the terminals 1, 2, in order that the reactances required may be reduced to convenient dimensions ; (2) the input impedance is rendered resistive at all frequencies by means of a suitably dimensioned resistance-capacity shunt across the terminals 1, 2 ; and (3) a further valve is connected to terminals 3, 4 for the purpose of compensating the loss of amplitude due to the introduction of the potentiometer and preventing reaction by raising the output impedance. Where the distortion has been produced by the use of more than one transformer coupling, more than two couplings like M1, M2 and more than one valve like T1 may be employed, Fig. 5 (not shown) ; or an approximate correction in which only two couplings M1, M2 are employed may be based upon an assumption with regard to the dimensions of the transformer responsible for the distortion.

Title: Improvements in or relating to reciprocating machines operable as pump or motor
IPC: F01B15/02
Filed: 1961-08-03
Abstract: 987,115. Reciprocating pumps and motors. S. HOLDENER. Aug. 3, 1961 [Aug. 5, 1960], No. 28176/61. Heading F1A. In a reciprocating machine operable as a pump or motor an eccentric pin on a shaft journalled in the pump casing reciprocates two equal prismatic pistons angularly displaced about 90 degrees each in a frame member separately guided in the casing so as to move in a direction perpendicular to the piston, each piston and frame member being arranged between a middle and one of two outer side plates, which outer plates include the inlet and outlet openings controlled automatically by the reciprocating movement of the pistons and frame members. Prismatic pistons 37, 58, Fig. 1, mounted respectively on needle bearings 38, 59 on an eccentric pin 5 of a drive shaft 4, reciprocate within similar frames 36 and 57 respectively. Each piston and frame arrangement is mounted between an intermediate plate 27 and an end plate 10 or 43. As shown in Fig. 2, frame 36 is slidable on sleeves 32, 33 mounted on needle rollers 30, 31 on bolts 28, 29 screwed into a casing portion 1. The frame 57 is similarly mounted on bolts 49, 50 and sleeves 53, 54, but is displaced by 90 degrees with respect to the frame 36. When the machine operates as a pump, anti-clockwise rotation of the pin 5, as seen in Fig. 2, causes the piston 37 to commence its downward stroke within the frame 36 which is caused to move to the left and thereby uncover the ports 11 and 12 in the end plate 10. The medium beneath the piston is thus expelled through a recess 40, Figs. 2 and 4, in the piston 37 and port 12 into an elongated chamber 7 in the main portion 1. The medium then passes through port 16, tube 20, axial bore 87 and radial bore 91 to a discharge chamber 94. The suction created at the top of the piston 37 draws the medium from a suction chamber 95 and thence through a radial bore 90, axial bore 68, tube 19, port 15 into an elongated chamber 6, from where it passes through port 11 and recess 39 into the cylinder space above the piston 37. On further rotation of the pin 5, the frame 36 is caused to move over to the right and thereby uncover the ports 13, 14 which are connected to the chambers 95, 94 respectively, by means similar to those connecting these chambers with the ports 11, 12. The piston 58 and frame 57 operate in a similar manner to the piston 37 and frame 36 but 90 degrees out-of-phase with the latter whereby a continuous flow is produced.
