Title: An improved construction of window sash fastener
IPC: E05F11/00
Filed: 1921-06-20
Abstract: 183,991. Bullock, A. June 20, 1921. Sliding bolts; door chains and the like.- A window-sash fastener comprises a lever 24 of channel formation, and having inturned flanges 40 extending to near the base to form a slot or runway, pivoted at 25 on one meeting rail 21a, and a sliding bolt 22 of inverted U-shape with projections 34 to engage the slot in the lever, mounted on a guide 23 on the other rail 20<a>. For fastening in the fully-closed position the catch 31 is raised to the position shown in Fig. 4, whereby the end of the bolt with the projections 34 enters the base of the slot in the lever, and the lever is swung down over the bolt and is held by the catch 31 engaging a depressed edge 42 of an aperture 41 thereof. To open the window partly the catch 31 is pulled back, whereupon the lever assumes a neutral position under the action of a spring 43, and the projections 34 ride in the slot of the lever, permitting the window to be opened for a distance equal to the length of the lever. To open fully, the catch 31 is pressed to the position shown in Fig. 9, in doing which it meets ears 47 on the sliding bolt and so withdraws it from the slot in the lever, which can only be done when the sashes are fully closed.

Title: Improvements in and relating to type-printing telegraphs
IPC: H04L17/30
Filed: 1920-06-23
Abstract: 146,123. Siemens & Halske Akt.-Ges. Dec. 16, 1918, [Convention date]. Type-printing telegraphs. - The receiving- arrangement of a type-printing telegraph system comprises two or more condensers successively charged by the signal impulses and discharged through a corresponding number of polarized relays which, together with rotary distributors, selectively close the printing magnet circuit. The line L is connected successively to the condensers k<1>, k<2> through the rotating brush b' of a distributor S1. Commutator switches t1, t2 discharge successively the condensers k<1>, k<2> through the operating-winding of polarized relays R1, R2 the armatures r1, r2 of which are adapted to engage contacts e1, f1; e2, f2 respectively. When the signal impulses cause the armatures r1, r2 to occupy the positions shown, the circuit of the printing-magnet D is closed through distributors S2, S3 as follows : battery B, armature r1, contact c1, segment v<1>1, and brush b3 of distributor S3, lead O passing through shaft w, brush b2 of distributor S2, segment v<4>2, contact f2 and armature r2 of relay R2, magnet D to battery, thereby causing the printing hammer h to be operated when a type Z corresponding to segment v<4>2 is opposite the hammer h. The number of signals adapted to be printed may be increased by increasing the number of relays, condensers, and distributor segments and the condensers may be charged from a source controlled by a line relay.

The flux is present in sufficient amount to lower the fusion point of the calcium sulphate which amount is at least 2 wt. per cent. based on the CaSO 4  exclusive of its water of hydration. The flux is a compound selected from the oxides, hydroxides and carbonates of a metal from groups Ia, Ib, IIb, IVa, IVb, VIIb and VIII and any other compound of a metal from Groups Ia, Ib, IIa, IIb, IVa, IVb, VIIb and VIII, the compound having a fusion point below 1450‹ C. when fired with CaSO 4 . The mass after setting may be fired at at least 1000‹ C. Many compounds which may be used as the flux are listed. Grogs some of which may also act as fluxes include fired clay, silica, alumina, zirconia, expanded perlite, pumice, silicon carbide, artificial and natural aluminium silicates (e.g. expanded vermiculite, analcite and andulusite), kyanite, orthoclase, spodumene, microcline, nepheline, syenite, andensine or other feldspar. Examples 33 to 37 describe the preparation of refractory masses from calcium sulphate hemihydrate, grog, and sodium hexametaphosphate. Examples 1-30 and 32 describe the preparation from compositions containing many different fluxes but no grog. The cement composition may be used for cementing an oil well easing.

Title: Improvements in television receivers
IPC: H04N7/16
Filed: 1947-06-30
Abstract: 647,893. Television transmission systems. BURGESS, A. F. (Zenith Radio Corporation). June 30, 1947, No. 17181. [Class 40 (iii)] Relates to receivers for counteracting the variations in transmitted television described in Specification 647,892, using a telephone or other line connected to an exchange which meters the time a key signal restoring a proper picture is received. The on-off switch of the receiver may automatically connect the supply of the key signal. For receiving phase inverted video and frame pedestal (synchronizing) signals, after detection the signals pass to a separator 29, Fig. 1, for frame synchronizing signals and also to an inverter switch 33 inverting the composite signal only when a particular tone is received from a telephone line 47 through a filter 45. The part 38 of the inverted frame pedestal or part 23 of the uninverted pulse corresponding to the original frame pedestal is used to actuate a gated D.C. inserter opened by pulses e from the scanner 30 and phase retarding network 40. A pulse f from the scanner 30 to the cathode of the receiver tube blanks the fly-back lines otherwise due to the synchronizing portions 36, 37 of the re-inverted pulse. The inverter switch 33 operates by blocking alternately, when a tone signal is received or not received, one of two signal input paths, one through a pair of valves, and one through a single valve producing phase reversal. Alternatively, for receiving pictures transmitted intermittently turned upside down and advanced backwards and forwards across a screen, the receiver may (i), when a line tone is received and detected at 129, Fig. 3, operate a gate 131 at instants when vertical (frame) pulses are received from a sync. separator 113 so that frame pulses are transferred to a valve relay 136 and scan reversing switch 137 restoring a proper direction of sweep of the sweep generator 114 ; (ii) after frequency division at 135 of the picture frequency to obtain the lateral movement frequency, operate a switch 118 inverting or not in polarity the line pulses from a blocking oscillator 116 in accordance with the reception or not of the tone and transferring them through a differentiating circuit so that the positive going pulses due to the differentiated leading or trailing edges of the positive or negative pulses trip a blocking oscillator 120 and generate sweep synchronizing pulses alternately delayed and advanced at the shift frequency of the transmitted pictures and the picture movement thereby stopped. Figs. 4-9 are the same as Figs. 6-11 of Specification 647,892.

In the form shown in Fig. 1, the feed tank 7, transmitter 1, and receiver 4 are connected to a casing 35 by pipes 39, 40, 41. The casing is divided by a partition 36 apertured at 37 and contains a piston 30 provided with an aperture 42 and a valve 33 normally closed by a spring 34, and acted on by a spring 38 ; pressure arriving from the transmitter moves the piston so that a valve 31 seats on the aperture 37, and the valve 33 allows rapid return of liquid from the receiver to the transmitter. A modification has a valve 43, Fig. 2, to allow when necessary rapid passage of liquid from the pipe 40 to the pipe 41, said valve being located in the piston 30, if desired. In another form, the piston 30 is provided with a member 46, Fig. 3, co-operating with grooves 49, 50 and acted on by springs 47, 48, which may differ in strength.

The pressure exerted by the indentor is determined by means of the weight 22 and arm 21 or by connecting a pressure gauge in the hydraulic circuit. The support 4 includes means for illuminating the indentation.
