Abstract: 1,141,575. VTOL aircraft. BÍLKOW G.m.b.H. 9 Aug., 1967 [11 Aug., 1966], No. 36605/67. Heading B7G. A V.T.O.L. aircraft includes a lift engine 7 mounted on a supporting device, e.g. a door 2 or an arm 15, which is either pivotable about or mounted to move transversely to a fore-and-aft axis 3 on or near the floor 4 of a recess in the aircraft, to firstly move the engine into and out of the recess the engine axis remaining aligned with the axis 3, and secondly, when the engine is out of the recess, to rotate the engine about a transverse axis Q or Qa (e.g. on a ball bearing 5 or on a bracket 16 rotatable about the arm 15) into and out of an operative position for vertical thrust. There may be a ball 18 and socket 19 locking device to hold the engine in the recess. In the embodiment shown in Fig. 2, the door 2 is rotated about the axis 3 by two hydraulic jacks (9, 10), Fig. 3 (not shown), the door carrying a motor (11), Fig. 4 (not shown), and gearing (12, 13, 14) for rotating a yoke 6 carrying the engine 7 in the bearing 5. With the engine 7 in the operative position the door 2 extends, at 2a, beyond the nozzle 7a of the engine helping to draw a flow K of cooling air between the engine and the door. In the embodiment shown in Fig. 5, the arm 15 is telescopic and is extended by a drive unit 17 before the engine is rotated to its vertical thrust position, thereby allowing a flow K of cooling air to flow between the engine and the aircraft.

Title: Process for rapidly cooking sausages, and apparatus therefor
IPC: A23L5/10
Filed: 1961-10-13
Abstract: 930,351. Cooking and smoking sausages &c. UNION CARBIDE CORPORATION. Oct. 13, 1961 [Nov. 1, 1960], No. 36788/61. Class 49. [Also in Group XXX] An encased, heat coagulable, comminuted meat emulsion (sausages) having at least a 3 to 1 surface to volume ratio is rapidly cooked by maintaining it at a temperature of from 180‹ to 250‹ F. in a stream of gas flowing at least at 2000 feet per minute, whereby the gas quickly coagulates the emulsion to form an encased self-supporting solid with smooth surface which permits easy removal of the casing. The emulsion may, for example, be cooked by maintaining it at 180-215‹ F. in a stream of gas flowing at 2000-4000 feet per minute for from 10 to 12 minutes, or may first be heated to 210-250‹ F. in a stream of gas flowing at least at 3000 feet per minute for from 5 to 6 minutes and then maintained at 160 ‹ F. in a gas velocity of at least 1600 feet per minute for from 5 to 7 additional minutes. There may be included in the meat emulsion a reducing agent, such as ascorbic acid or one of'its non-toxic salts, in amounts of from 0.03 to 0.10% by weight. The process may be operated batchwise or continuously. Examples are disclosed. Sausages 10 are rapidly cooked in a tunnel 4, Fig. 1, or in a pair of cooking tunnels in tandem relationship, by hot smoke-containing air, of which the humidity is controlled by steam injection 26; vanes 24 are fitted along the inner surfaces of the top and bottom walls of the tunnel for re-directing the flow of gas towards the sausages. These are conveyed continuously or in batchwise operation on either wire hooks 12, Fig. 3, affixed to a chain 8 (the hooks are spaced to allow for sausage shrinkage during cooking) or an open mesh conveyer belt 30, Fig. 5. In the former case, every second sausage link is engaged by a finger 50, Fig. 2, from which it is pushed sideways on to an aligned hook 12 by a pusher arm 52. At the output end of the tunnel, an intermittently operated paddle wheel 60 doffs the sausage strands sideways from the hooks 12.

Abstract: 932,092. Lathe details. USINES TORNOS, FABRIQUE DE MACHINES MOUTIER S.A. Nov. 5, 1959 [Nov. 6, 1958], No. 37531/59. Class 83 (3). A bar-fed mechanism for an automatic lathe having a headstock 3, Fig. 1, rotating the bar 6 and cutting tools 16, 17, 21 for producing a series of identical workpieces, comprises a drum 25 containing a number of longitudinallyslotted tubes 25a, Fig. 2, each carrying a bar 6, the drum being indexable to align the tubes successively with the headstock axis. A pusher 26 is provided in each tube, and that one in the tube aligned with the headstock axis is engaged by a link 27 carried by an endless chain 28 driven by a continuously-energized electric motor 31, thus urging the bar towards the headstock. When the bar has been substantially used, the link passes around chain-wheel 29 and draws the pusher and bar-end away from the headstock until the link 27 engages cam 47, Fig. 4, and is disconnected from the pusher. As the link moves around chain-wheel 30, it depresses lever 48 to release detent 51, thus allowing the drum to be turned by weight 33 to bring another tube into alignment with the headstock. The link moves on to engage the pusher of that tube to feed the bar therein, and this is repeated until all the bars have been used. Specifications 917,158 and 917,159 are referred to.

Abstract: 363,506. Loading. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 15, 1930, No. 37793. Convention date, Dec. 16, 1929. [Class 40 (iv).] In order to avoid non-linear distortion due to hysteresis of loading material in conjunction with the high input level required for a long-distance Krarup cable, the cable is terminated with Pupinized portions the coils of which have a hysteresis factor such that the Pupin portion has a lower factor than a similar length of Krarup cable. The low hysteresis factor may be obtained by use of material of low hysteresis number or of coils of large core volume and Specification 354,523 is referred to for an explanation of this matter. The inductance and distance between the loading coils may be arranged so that the connections between the two kinds of cable are free from reflection. Specifications 335,108, [Class 40 (v), Wireless signalling &c.], and 353,629 are also referred to.

Title: Breathing apparatus
IPC: A62B7/02
Filed: 1971-08-18
Abstract: 1358303 Breathing apparatus AGA AB 18 Aug 1971 [24 Aug 1970] 38821/71 Heading A5T Breathing apparatus comprises a rebreathing system from which exhalation to the ambient medium is possible, connected to a fresh gas supply 46, and a control for maintaining the breathing system closed with respect to the ambient medium during a series of breaths, and opening the system for exhalation to the ambient medium after the series of breaths. Control is effected by a valve device which operates in dependence on a parameter determined by the breathing of the user e.g. volume of gas breathed, number of breaths. Air is supplied to a mouthpiece 41 from a bellows type breathing bag 39 through an inhalation valve 43, and is returned to the breathing bag via a filter 40 for carbon dioxide removal, and an exhalation valve 44. On inhalation the upper wall 47 of the bag pivots about an axis 48 to which it is hinged, Fig. 6, and swings a lever 50 downwardly whereby a pawl 51 on the lever abuts the periphery of a toothed ratchet wheel 52 Fig. 7 and turns the wheel. On exhalation a stem 55 of the opening exhalation valve 44 engages slots 56 in the wheel, and the wheel is prevented from rotating back with the now upwardly pivoting lever 50 and wall 47, by a fixed pawl 53. As the wheel is turned by successive inhalations, a position comes in which the stem 55 abuts a land between the slots 56 and prevents exhalation through the valve 44, and exhaled breath is forced out of valve 42 to the ambient medium. A subsequent inhalation turns a handle 45 and admits fresh air to the bag. Abutments 57A may be provided at the ends of a slot 57 through which the lever 50 projects Fig. 7, to limit the movement of the wheel per breath, whereby fresh air may be admitted to the bag after a preselected number of breaths. In a further embodiment, Fig. 8 (not shown) the toothed wheel is replaced by two toothed wheels (58) and (59) on a shaft (60) the latter wheel being toothed at only diametrically opposed parts of its periphery and an arm (61) replaces the lands between slots in a wheel. A pawl (62) attached to a hinged bar (67) turns the wheels when the bar is pivoted by a push rod (66) due to compression of the bag. The push rod is slidable on the bar and its position on the bar is determined by bellows 68, which contract at high pressure and expand to the position shown in broken lines at atmospheric pressure. A pawl (63) engages the toothed portions of the wheel (59) when the arm (61) prevents the valve (44) from opening, and the air is exhaled to the ambient medium. A demand valve (71) Fig. 9, (not shown) may be connected to the fresh gas supply to cause gas to be supplied to the breathing bag if its pressure drops to a predetermined level, and when exhalation to the ambient medium takes place the bag is completely implied through a relief valve (8). The storage container may be replenished during exhalation to the ambient medium, Fig. 10 (not shown).

The walls and frames are preferably constituted by spaced vertical rods, the stationary and movable sections being in the form of rails at the upper ends of the rods. Means are provided for manually or automatically controlling the movement of the movable sections in synchronism with the rotation of the basket. In operation, the end of the flexible member is secured to the base plate between the frame 7 and the adjacent wall 10 at the level of the free ends of the movable sections. The movable sections are articulated by means of vertical rods lying on a radius of the basket. The movable sections are moved to their first positions and the basket is rotated to lay the flexible member in the form of a spiral between the adjacent frames and walls. The outer turn of the spiral is positioned by movement of the movable sections to their second position. A further rotation of the basket lays a second turn of the flexible member in the outer position. The movable sections are then moved to their third position and rotation of the basket lays the flexible member in spiral form. The procedure is repeated until all the flexible member is coiled.
