Abstract: 405,109. Window &c. fastenings. CRITTALL MANUFACTURING CO., Ltd., and CRITTALL, W. F., Manor Works, Braintree, Essex. Jan. 17, 1933, No. 1582. [Class 44.] A casement window fastener 21 is secured by a sliding bolt 6 moved by hand to engage under the fastening arm 18 and retained by a spring- pressed detent 13 which can be disengaged from the bolt by a key 25 arranged at about 45‹ to the plane of the window and pointing inwards towards the window 20. The bolt 6 of triangular crosssection slides in a triangular casing consisting of a back plate 1 and a cover plate 2 secured thereto by screws, and has a triangular recess 29, the V-sectional portion thus formed sliding in a correspondingly shaped channel in the casing, between a triangular rib 5 and the cover plate 2. The bolt is pressed to its inoperative position by a spring 10 housed in the recess 29. The rib 5 receives the screws 8 whereby the casing is secured to the fixed frame 9 so that the side face 16 of the back plate is flush with the side face of the flange of the fixed frame and no plaster has to be cut away. The spring-pressed detent 13, housed in a recess 11 in the casing, engages with an aperture 15 in the bolt and can be withdrawn by a key 25 which engages with a notch 23. Projections may be provided on the casing so that a special key is required to operate the detent. The casing may be formed with another recess 12 for the detent so that it may be inverted for an oppositely opening window, the plunger being suitably modified. The fastener 21 abuts against a fixed stop 22 on the window when fastened. The surface of the striking plate 28 which is inclined as usual lies flush with the surface of the back plate. When the window is closed, the back plate 1 and the bolt 6 lie close against the window 20 to prevent the entrance of a tool for forcing the window.

Abstract: 546,542. Wringing machines. BRITISH THOMSON-HOUSTON CO., .Ltd. Feb. 7, 1941, No. 1684. Convention date, Feb. 7, 1940. [Class 138 (ii)] A lamp is mounted within a shade 68 carried by the control bar 40 of a wringing machine to illuminate the work during the squeezing action. The wringer has two rollers 26, 27 adjustably swingable about a pillar 4 and lockable in a plurality of angular positions by a hand bolt 7 engaging one of a ring of holes in a fixed horizontal disc 9. The driving shaft 4 carries a pinion 11 which engages one or the other of two crown wheels 12 slidable on their shaft 14 to impart forward or reverse motion to the lower roller 26, through a detachable connection 34, 36. The upper roller 27 is carried by arms 76 having projections 43, 44 which engage rolls 53, 56 in a vertically slidable and spring-pressed frame 46. When the arms 76 are vertical the upper roller 27 is raised out of contact with the roller 26, and lamp contacts 59, 60 are broken to extinguish the lamp. When the bar 40 is pulled forward the projection 43 engages rolls 53 and the projection 44 takes under the rolls 44, thus levering the roller 27 down upon.the work, and making the lamp circuit through a sliding rod 79, pressed by the lower flat side 59 of an arm 76. Roll guards 30, 32 tilt a drain board 63, pivoted on bosses 64, when the bar 40 is actuated. Swinging of the bar 40 also throws one of the crown wheels 12 into engagement with the driving pinion 11 through a stationary pin 24 engaging a bayonet slot 23 in the cage 20 carrying the wheels 12.

Title: Improvements relating to phase modulation
IPC: H03C3/14
Filed: 1942-02-12
Abstract: 552,946. Frequency and phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 12, 1942, No. 1885. Convention date, Feb. 12, 1941. [Class 40 (v)] . Phase modulation is produced from frequency modulation by beating the frequency-modulated wave with a, wave of constant frequency, passing a resultant through a path giving a phase .displacement dependent on frequency, and then again beating this phase-displaced wave with the original frequencymodulated wave to remove the frequency modulation. In the transmitting circuit shown, oscillations generated by the valve 50 are frequency-modulated by a reactance valve 54 controlled by a signal input at 6. A constantfrequency oscillator 80 beats with the frequencymodulated oscillation in a mixer valve 28, the output circuit of which includes a phasing-circuit, such as the circuit 30 tuned to the beat frequency. The phasedisplaced frequency-modulated output wave is combined in a mixer valve 92 with the original frequency-modulated wave, producing a phasemodulated wave in the tuned output circuit 98 of the same frequency as the constant-frequency oscillator 80. If a network giving an output which varies inversely with the signal frequency is interposed between the signal source 6 and the valve 54, the final output at 7 is a frequency-modulated wave. Other forms of phasing networks may replace the tuned circuit 30. In a receiver, a frequency-modulated wave may be converted to a phase-modulated wave as above described, and then de-modulated by combination with a local carrier. Reference has been directed by the Comptroller to Specification 534,955.

Specified plasticizers include dibutyl sebacate, desirably present in a proportion of 7 to 10% of the vinylidene chloride polymer, and diisobutyl adipate, 2-ethylhexyldiphenylphosphate, and acetyl tri-n-butyl citrate, desirably present in a proportion of 7 to 12%.
