IPC: B64C1/00
Filed: 1921-01-10
Abstract: 157,940. Nimf³hr, R. Sept. 23, 1913, [Convention date]. Void [Published under Sect. 91 of the Act]. Aeroplanes and ornithopters; planes, construction and arrangement of. - A flying-machine is provided with main wings 6, 7 adapted to be drawn in against the body or extended by lazy-tongs bracing 8, and with a crescent-shaped tail 4 supported by telescopic stay-rods which allow the plane to be folded upwards against the rear of the body, flapping wings 36, 37 being pivoted to the ends of the main wings. The bracing 8 is connected to bearings 9 which may be slid along vertical rods 10 for folding or extending the wings, a telescopic connection at 11 being secured by a clamp 12 operated from the pilot's seat. The rods 10 are connected by ball-and-socket joints 13 to rods 14 arranged to slide transversely of the machine upon rollers 17 on the body. The wings 36, 37 may also be collapsed by means of a lazy-tongs connected to the ribs. Steering and balancing.-The tail can be adjusted about an axis parallel to the direction of flight and also about a tranverse axis. The main wings 6, 7 may be adjusted about their fore-andaft pivotal connections to the body by sliding the rods 14 transversely of the machine by means of a rope passing over a pulley and connected to the rods. These wings may further be warped by raising or lowering the rear ends of their connections to the body, and may be drawn in or extended as described above. Automatic stabilizing is effected by means of control members each comprising a box 24, Fig. 8, over which is stretched a diaphragm 26 supporting a weight 25, which acts by inertia, when the equilibrium of the machine is disturbed, to displace the diaphragm to one side of its normal position thereby transmitting air through a pipe 27 to a similar diaphragm box 28 which actuates an auxiliary motor by means of rods 29 so as to operate the appropriate controls. Longitudinal tilting is counteracted by a control member 21, Fig. 2, carried on a folding jib 5 and actuating an auxiliary motor which folds or extends the wings and adjusts the tail-plane. Lateral tilting is counteracted by control members fitted on the wings 6, 7 and controlling a motor which adjusts or folds the wings 6, 7 or 36, 37, or causes wing-beats of the wings 36, 37. Similar control devices are provided for preventing unintentional rotation about a vertical axis, and also movements of translation along the three axes. Propelling.-Front and rear propellers 2, 3 are provided, the rear propeller being smaller and revolving at a higher speed than the front one. The two propellers are driven independently and may rotate in opposite directions. Indicators, applications of.-The control members such as 21, Fig. 2, are referred to as indicators for recording the disturbances to which the machine is subjected.

Title: Improved manufacture of phosphoric acid
IPC: C01B25/18
Filed: 1923-01-18
Abstract: Pure phosphoric acid is produced by decomposing by means of sulphuric acid barium phosphate obtained by the treatment of di- or tri-sodium phosphate with barium sulphide.  In an example, to a solution of barium sulphide crystallized di-sodium phosphate and a solution of caustic soda are added until no further precipitation occurs.  After filtering and washing free from sodium sulphide which may be recovered, the precipitate of barium phosphate is decomposed by means of sulphuric acid and the barium sulphate removed.  In another example sodium phosphate is formed by treating commercial phosphoric acid with sodium carbonate and caustic soda.  Barium phosphate is then precipitated by means of barium sulphide and treated as in the first example.  Potassium and ammonium phosphates may be used in place of sodium phosphates.ALSO:Barium phosphate is produced by treating barium sulphide with di- or tri-sodium phosphate.  The barium phosphate precipitated is filtered off and the sodium sulphide in solution may be recovered as a bye-product.  Ammonium or potassium phosphates may be used in place of sodium phosphates.

Title: Improvements in or relating to hot-gas reciprocating engines, and gas refrigerators and heat-pumps operating on the reversed hot-gas reciprocating engine principle
IPC: F02G1/053
Filed: 1955-01-21
Abstract: 764,221. Hot gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Jan. 21, 1955 [Jan. 22, 1954], No. 1894/55. Class 7 (1). [Also in Group XIII] In a hot gas engine comprising a closed lubricating system and a pump by means of which lubricant is pumped from the crank case to one or more areas of lubrication, the lubrication system is constructed in such a manner that the lubricant is in thermal contact in a cooling space with a cylinder wall, whilst the lubricant serves at the same time to prevent gas leakage, the cooling space being located in a manner such that the lubricant exerts a hydrostatic pressure on an area to be sealed and provision is made of means to maintain this hydrostatic pressure whenever the pump stops. Refrigerating engines are described in the refrigerator shown, a pump 16 draws lubricant from the crank case and supplies it under pressure to a passage 22 which teeds lubricant for example to the crank shaft bearings, and if necessary through the connecting rods 4 and 6 to gudgeon pins (not shown). The lubricant flows to an annular space 23, the lubricant in which prevents gas leakage from the crank case. From the space 23 the lubricant can flow through the duct 14 to a cooling jacket 13 in which the lubricant is in thermal contact with the wall of the cylinder 1 so that the latter is cooled. Fig. 2 shows a non-return valve comprising a resilient e.g. rubber ring 26. A spring 28 contributes to the sealing effect of the ring 26. An annular member 30 is urged to the left by springs 34 and an annular metal plate 33. Fig. 3 shows a modified arrangement comprising a valve 38 in the return line to the crank case. Each refrigerator is driven by an electric motor 12. The invention applies to double acting apparatus. A filter 19 is fitted in the crank case. The working medium may be hydrogen.

Title: Improvements in or relating to radio and like receivers
IPC: H03G5/26
Filed: 1937-01-22
Abstract: 470,372. Wireless receiving circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Jan. 22, 1937, No. 1984. Convention date, Jan. 22, 1936. [Class 40 (v)] The selectivity of a radio receiver is automatically regulated in dependence upon the strength of high audio frequencies derived from the audio frequency portion of the receiver. In the embodiment shown, G is the signal rectifier and N a low-frequency amplifier, part of the output from which is applied to a second rectifier GL through a high pass note filter K which selects the higher audio frequencies. The resultant voltage is applied to vary the grid bias of a valve R acting as a variable damping impedance in series with a coil in the radio frequency filter network B ; the selectivity is thereby increased as the high note frequency amplitude increases. Alternatively the control voltage may be applied to vary the coupling of network B or both damping and coupling.

Patent GB-565014-A (GB)
Title: Improvements relating to systems for the automatic control or recording of a variable value or condition
IPC: G05D23/22
Filed: 1943-02-09
Abstract: 565,014. Automatic control and recording systems for electric and other furnaces &c. ABBOTT, W. F. Feb. 9, 1943, No. 2173. [Class 38 (iv)] [Also in Groups XXXVII and XXXVIII] Temperature; variables in general.-A highly sensitive contact-making galvanometer system, in which " high " and " low " contacts may be set in very close mutual relation without causing hunting, has two galvanometers with their operating coils in parallel, and their moving contacts equidistantly disposed in relation to mean fixed contacts when a desired condition prevails. This relation will be disturbed under other circumstances to cause the selective operation of relays to cause correction of the condition or to actuate recording means. A relay R4 controlling the heat supply, for example the current supply to a furnace heating element A, is controlled through contacts r<SP>30</SP> of a relay R3 which is controlled by relays R1, R2 respectively in series with the moving contacts g, g<SP>x</SP> of galvanometers G1, G2. The coils of these galvanometers are connected in parallel and in series with a thermo-couple B, balancing Wheatstone bridge D, with temperature setting potentiometer C, and a resistance R. When contact g moves towards its companion fixed contact, the contact g<SP>x</SP> moves away from its fixed contact and vice versa. The galvanometers may be set by adjustment of their fixed contacts or tension heads so that under normal conditions (1) both pairs of contacts are lightly engaged, (2) both pairs are engaged with substantial pressure, or (3) both pairs are separated to an equal extent ; the effect of their operation upon the heat supply will correspond respectively with Figs. 2, 3 and 4 in which the line H shows the duration of the periods of application of heat when obtaining a temperature T maintained between limits T1 and T2. The circuits and the relays R1, R2 pass through the contacts g, g<SP>x</SP> respectively and through the resistance R which affords a potential difference in the galvanometer circuit to cause additional current in the coils of the galvanometers when a relay circuit is closed, thus reinforcing the contact pressure of one galvanometer contact in that circuit and separating or increasing the separation of the galvanometer contacts in circuit with the other relay. For recording purposes the relays may control a reversible motor which operates the potentiometer C to rebalance the bridge and also actuate a recording plan.

Abstract: 756,975. Door-operating apparatus. EXPRESS LIFT CO., Ltd., and FALK, D. A. Jan. 18, 1955 [Jan. 25, 1954], No. 2216/54. Drawings to Specification. Class 65 (1). In a door-operating system for a lift or the like in which the cage door and the shaft door opposite which the cage is stopped are mechanically coupled together so as to be operated by a single power means and in which each door has an edge portion responsive to obstruction of the door during closing, the edge portion of the door which is indirectly operated is connected to mechanical means for transmitting an indication of obstruction to means on the other door whereby the operation of the power means is stopped or reversed. The edge portion of the directly-operated door may act on the same control means or independent means. In the arrangement described, the two doors are operated by power mechanism carried on the cage, and the edge portions of the doors are mounted on parallel links to move upwardly and inwardly on meeting an obstruction; the upper end of the edge portion of the shaft door abuts a roller on a slidable member which, when the edge portion of the door moves upwardly, acts through a linkage to swing out an arm to engage and operate a switch-actuating cam on the cage door.
