Title: Improvements in and relating to casement windows
IPC: E06B3/34
Filed: 1937-02-22
Abstract: 490,822. Windows. BOOTH, W. C. Feb. 22, 1937, No. 5245.. [Class 20 (iii)] The hinged stile of the sash frame of a casement window is divided longitudinally, as shown in Fig. 1, the outer part 5 being hinged to the fixed frame 9 on the outside thereof and the inner part 6 being hinged to the outer part 5 on the inside thereof, and the portions of the sill 12 and head-rail 17 which normally abut the sash frame are hinged to turn downwardly and upwardly, respectively, from these positions, as shown in Fig. 2. The sill 12 is held in its normal position by a bolt provided in a recess 14. The rail 17 is shaped with a step 20 which normally engages the top rail of the sash. When it is desired to turn the hinged sash inwardly, the rail 17 is pushed upwardly into a recess 16 in the head of the fixed frame ; the sash is turned slightly about the outer hinge 8, and the two parts 5, 6 of the hinged stile are then capable of being moved relatively to each other about the hinge 10. In returning the parts to the closed position from the position in which the sash is swung inwardly, the top rail of the sash engages the rail 17, which is then in its lowermost position as determined by recesses 19 in the side members of the fixed frame, and moves the rail 17 upwardly into the recess 16. When the sash is in its closed position, the rail 17 automatically drops into engagement with the top rail of the sash. The hinged sash of the metal casement shown in Fig. 3 is formed of a channel-section 31 and a Z-section 34, these members being hinged together at 33 and the member 34 being hinged to the fixed frame 36 at 35. The sashabutting portions of the sill and head-rail, in this construction, are of L-section, and, when the window is open, are swtmg into a horizontal position in which they are partly housed in channelled portions of the fixed frame.

Title: Circuit arrangement for tabulating devices in electrical typewriters, invoicing or like machines
Inventor: LOGISCH HELMUT
IPC: B41J25/18
Filed: 1968-02-02
Abstract: 1,212,792. Selective signalling. KOMBINAT ZENTRONIK VEB. 2 Feb., 1968, No. 5399/68. Heading G4H. In a typewriter carriage tabulating control system key-units KU, each comprising a key 9, a trigger 1 and gates 3, 7, 13, 25, are selectively plugged P to sockets 23 corresponding to desired tabulating positions of the carriage, and each time a key (9 or 9<SP>1</SP> or 9<SP>11</SP>) is depressed the carriage is driven to the desired position via the shortest route, the direction of travel being determined by triggers 1 which for each keyunit, register whether the actual position of the carriage is in front of, or behind, the corresponding tabular position. Initially the carriage has to be in the extreme left-hand position in which position a wiper 20 on it is in the position illustrated. Triggers 1 are reset to produce a high output from their right-hand sides, thereby priming gates 3, and a contact 4 is in the position shown. Depression of any key, e.g. key 9<SP>1</SP>, then applies a signal via gate 3 (all square symbols being isolating amplifiers), and an OR gate 14 to a forward solenoid 11. The carriage then moves forward until the contact 20 attached to the carriage marks the socket which corresponds to key 91. When this occurs the trigger 1<SP>1</SP> is switched over, closing the gate 3<SP>1</SP> and the carriage stops. Also a signal passes via key contacts 9<SP>1</SP>a, 9<SP>1</SP>b, and contact 11b to energize a solenoid which releases any depressed key 9. As the carriage advances, as just described, if its contact 20 passes over a socket to which another key-unit is plugged, the trigger of that key-unit is changed over. Thus, in the example described, during forward movement of the carriage to the position corresponding to key 9<SP>1</SP>, the trigger 1 associated with key 9, will be changed over. If, subsequently, key 9 is depressed, a signal will be passed via gate 13 (and not gate 3) and OR gate 27 to energize a backward solenoid 17. Whilst backward movement of the carriage is occurring the contact 4 is changed over, which ensures that the triggers 1 of any plugged sockets that are passed over are switched to produce a high output from their right-hand side, and line-feed is effected. Once the desired plugged contact is marked by the carriage contact 20, the reverse drive is stopped, but it is arranged that overshoot occurs and the carriage finally reaches its desired position by a short forward movement.

Abstract: 584,967. Submarine mines. MIDGLEY, A. H., and HUSKINSON, P. March 27, 1940, No. 5524. [Class 9 (ii)] A floating mine, stated to be particularly adapted for dropping into rivers or other shallow waters, is combined with a sinker which is released by impact with the water to permit extension of a flexible connection between the sinker and the mine so that the sinker provides a bottom anchorage leaving the mine to float at a predetermined level. As shown, the sinker a is normally secured over the baseportion b of a mine of the kind described in Specification 583,788 by means of a ring e which retains a series of balls f in engagement with apertures d in the part b. The ring e is held in the position shown by tongues g<1> projecting from thin washers g secured by setscrews h. On impact with the water, the tongues g<1> are bent (or broken) by the inertia of the ring e which falls away to free the balls f whereupon the sinker becomes detached from the mine. To assist this separation, a spring k is shown fitted around the casing of the soluble plug c by which the mine is armed through the entry into the apertures d. The flexible connection (not shown) between the mine and sinker may be coiled in a recess m, or around lugs, on the sinker. For security during transit or storage, the ring e may be locked in position by a headed pin i secured by a splitpin i<1>.

Abstract: 559,514. Polyamides. DU PONT DE NEMOURS & CO., E. I., and PETERS, F. T. May 7, 1941, No. 5905. [Class 2 (iii)] Synthetic linear polyamides, e.g. as described in Specifications 461,236 and 461,237, preferably interpolyamides, are plasticized by incorporating therewith an ester derived from a monocarboxylic acid containing at least 6 carbon atoms and a polyhydric alcohol in which at least one of the hydroxyl groups is left unesterified. The ester may be prepared by heating a fatty oil, e.g. castor oil with propylene glycol &c. in presence of a catalyst, e.g. lead oxide, sodium alkoxide, sulphamic acid or sulphuric acid. The materials are mixed by means of a mutual solvent, e.g. formic acid, mixtures of chloroform and methanol, ethanol and water or by melt blending. There are specified as partial esters the mono esters of caprylic, pelargonic, caproic, lauric, palmitic, stearic, oleic, ricinoleic, salicylic acids with ethylene, propylene, diethylene, butylene, pentamethylene, hexamethylene, deca - methylene glycols and 1.12-octadecanediol ; mono- and di-esters of above with glycerol ; partial esters of sorbitol. The plasticizing effect is increased by the addition of water ; alcohols-methanol, propanol, isobutanol, benzyl alcohol, cyclohexanol, hexmethyleneglycol, glycerol; dibutyl phthalate, tricresyl phosphate ; monomeric amides boiling over 200‹ C. ; cyclic ketones; high boiling phenols ; sulphonamides. Lustre modifying agents, pigments (carbon black), fillers, dyes, antioxidants, oils, antiseptics, and cellulose derivatives may be added. The plasticized products are suitable for use as yarns, fabrics, bristles, fishlines, dental floss, safety glass interliners, adhesives, insulation, leather applications, raincoats, umbrellas.

Two-stroke-cycle engines; driving- gear; cylinders, admission ports and' passages of.-An inverted two-cylinder Diesel engine driving through a beam i has the air pumps n arranged directly under the cylinder b remote from the crank shaft and driven by means of a rod o from the piston d in this cylinder. The pump may be single or double-acting. The size and position of the beam i is chosen so that in working the connecting rods e, f do not cross the axes of the cylinders a, b ; as a consequence the side thrust on the pistons is continuously towards the sides of the cylinders where the admission ports l, m are arranged. Two cylinders and their water jackets are cast in one, the spaces between the jackets forming a receiver q for the air from the pump. There are two sets of air admission ports to each cylinder; the lower set l are used for scavenging air and close with the exhaust ports. The upper set m are covered by the piston after the exhaust ports are closed; air to these ports is controlled by a rotary or oscillating valve s, one valve controlling the supply for the two cylinders. The super-charging air to the ports m is either supplied from a high pressure reservoir or as shown the valve s is housed in the receiver q and the air from the pump n is used. The pump &c. balances the main connecting rod k. Each set of cylinders as described above is formed with vertical flanges u, Fig. 2, by which it can be bolted to a second set thereby enabling a multi-cylinder engine of any number of cylinders to be built. End plates v close the receiver q, which passes right through the builtup engine. All the valves s are driven from one spindle t.
