Title: Improvements in door-locking apparatus
IPC: E05C19/00
Filed: 1946-05-08
Abstract: 611,795. Stay-bar fastenings. MAGUIRE, R., and MAGUIRE, R. May 8, 1946, No. 13968. [Classes 44 and 65 (i)] To prevent forcing of a door 15, a stay-bar 2 is attached by a link 3 to an angle iron wall abutment 1, and rests at its free end on a catch bar 7 in an abutment 4 fixed to the door, the catch bar 7 being pivoted at 8 and normally supported in a slot 6 in the abutment 4 but operatively connected to the lock 10 by a link 12 so that when the lock is unlocked the bar 7 is withdrawn from the slot 6 and falls, allowing the stay-bar 2 to fall from the abutment 4. In closing the door, the stay-bar slides on the top of the flange of the abutment 4 until when the door is closed it drops on to the catch bar 7. The bar 7 may be replaced by a bell crank lever, one arm of which supports the stay-bar while the other is operated by a part of the lock.

Title: Improvements in or relating to reed organs
IPC: G10B1/08
Filed: 1959-04-24
Abstract: 868,395. Organs. MAGNUS ORGAN CORPORATION. April 24, 1959 [Oct. 15, 1958], No. 14027/59. Class 88 (2). A reed organ has a piano-type keyboard and a keyboard for playing chords, compressed air being supplied to a first chamber for vibrating reeds controlled by the " piano " keys and a restricted passage leading the compressed air from the first chamber to a second chamber for vibrating reeds controlled by the chord keyboard. Air delivered by blower 5 passes from chamber 3 into chamber 11 extending the full length of the keyboard. Reeds 13, Figs. 3, 7, are aligned with slots 14 in plates 14a, which slots lead to passages 17 defined by a housing 12 and partitions 15. When a key 7, 8 is depressed its upward extension 7a, 8a is moved away from the associated passage 17 to permit air to escape from chamber 3 through chamber 11 and passage 17 whilst vibrating associated reed 13. A restricting passage 25 in wall 10 leads air through compartment 26 and passage 27 to chamber 23, Figs. 2, 4. On depression of a chord key 20, key extension 21a is moved away from passage 33 and compressed air escaping from chamber 23 through passages 33 causes a set of three reeds 30 to vibrate. The chords may be softer than the melody. Microphones may be provided within the casing for connection to an external reproducer. Each key of the " piano " keyboard may serve two reeds of slightly different pitch to provide " vibrato," Figs. 9, 10 (not shown).

Filed: 1927-05-26
Abstract: 271,888. Soc. pour l'Exploitation des ProcÚdÚs et Brevets M. Fichter (Soc. .Anon.). May 27, 1926, [Convention date]. Stroboscopic apparatus.-For the purpose of observing simultaneously periodical phenomena of different periodicity each part is given a distinctive colour and examined in light of a different colour, preferably that of the same colour as the part it is desired should not be visible. The invention is described with reference to the calibration of electric meters, somewhat on the lines described in Specification 209,396. In one example the disc bears two series of radial marks 2, 3, one being green and the other red and of different spacing. The disc is observed through a telescope having a rotary shutter in the eyepiece, either under red or green monochromatic light, so that the meter can be standardized for a given load C, or for loads C, C &c. when viewing the 2 4 green marks 2 under red light or for loads C, C 3 6 &c. when viewing the red marks 3 under green light. In a further example three sets of marks are used coloured red, green, and yellow the outer rows of which differ in number from the middle row by an equal amount, e.g. they may be 99, 100, and 101 respectively, so that if one or other of the outer rows appear stationary.when under appropriate observation, the error is not greater than one per cent. The eye-piece of the telescope mav be provided with coloured screens to enable ordinary light to be used for illuminating the disc.

Abstract: 667,936. Milling-cutters. BEGLE, H. E. June 8, 1950 [June 27, 1949], No. 14367/50. Class 83 (iii). A milling-cutter has detachable blades 2 in the form of regular polygonal prisms, preferably octagonal and of solid tungsten carbide, and the seating surfaces of the blade-receiving slots in the head 1 are oriented so as to give the required rake angles to the blades; the blades have facets 5 perpendicular to the plane faces 4 and, as each corner becomes worn, it can be rotated through 45 degrees to present a new corner until all eight corners on one face have been used, when the blade can be reversed and the process repeated with the corners on the other face, before it is necessary to discard the blade or regrind it to suit a smaller cutter. The main seating surface 7 preferably gives a negative axial rake of 3 degrees and a negative radial rake of 10 degrees and the other surfaces are constituted by a surface 9 and by a locating pin 8 which determines the projection of the blade from the operative face of the head. The blades are each clamped by a cylindrical wedge 10 having a flat 11 and by a screw 13 which passes through the wedge to engage a threaded hole 14 in the head. For extracting the wedge, the head of the screw 13 abuts against a bush engaged in threads 16 in the wedge, of opposite hand to those of the screw.

Abstract: 837,487. Etching. BIRMETALS Ltd. Aug. 7, 1958 [May 8, 1957], No. 14607/57. Class 100(2) Apparatus for etching curved surfaces comprises means for supporting and traversing a surface to be etched, elongated projecting means extending parallel to the surface to be etched for the full dimension in a direction transverse to the direction of traversing and adapted to project medium with substantially uniform force in paths spaced along the elongated projection means. Paddles 4 splash etching medium 5 against a baffle 7 and thence upwards against a cylinder 9 through a slot 13 in a mask 12, surplus medium returning through slots 14. Elongated projecting means 15 comprising pipes with rows of perforations or slots direct medium against the cylinder radially or in a direction inclined towards the direction of rotation of the cylinder, which is rotated or oscillated by an electric motor. Similar projecting means 16 project a dispersing fluid such as air against the cylinder to cause trickles of etching medium moving circumferentially down the cylinder to form into a more or less unified flow. The projection means 15, 16 are carried on a housing 19 which is reciprocated by rods 20 slidable in stationary bearings by a crank. In another form, the projecting means are annular and are spaced axially along the cylinder which is axially reciprocated and may also be rotated or oscillated, alternate projecting means projecting etching medium and dispersing fluid. The apparatus may be used as auxiliary mechanism attached to the apparatus disclosed in Specification 725,110.

Abstract: 752,260. Automatic bunker discharge: conveyers. GREBE, K. May 18, 1954, No. 14618/54. Class 78 (1). A bunker closure device for feeding to conveying belt section 20 of the kind in which the 'said belt section 20 automatically contacts and operates control devices 8, 10 which actuate the pressure fluid motor 5 which in turn operates the bunker closure 1, is characterized by an arrangement of the control devices such that on operation of only one control device the closure remains closed while on the operation of both of the control devices the closure is opened. As shown, the belt section advances from the left, the closure 1 being closed. When the belt section contacts control device 10, air from source 14 passes along pipe 9 as far as control device 8. When the belt section later reaches the said control device 8, the latter is actuated and air passes into pipe 7 to actuate valve 4 which causes motor 5 to open closure 1 so that material falls on to the belt section. When, however, the left end of said section has passed control device 10 the latter shuts off air from source 14 and the closure closes to stop the fall of material.
