Title: Improvements in and relating to direct reading radio compasses
IPC: G01S1/02
Filed: 1932-04-02
Abstract: 380,385. Directive wireless signalling. BRAILLARD, R., 55, Avenue Beau- Sejour, Uccle, MARIQUE, J., 249, Avenue Brugmann, and SOC. ANON. INTERNATIONALE DE TELEGRAPHIE SANS FIL, 13, Rue Brederode, both in Brussels, both in Belgium. April 2, 1932, No. 9514. Convention date, April 3, 1931. [Class 40 (v).] A direct reading radio compass comprises a mirror galvanometer 9 receiving a rectified current derived from an exploring system constituted by a frame aerial 2 or radio-goniometer, rotating with the galvanometer, a luminous spot 14 from the galvanometer mirror 10 describing, by persistence of vision, a continuous luminous polar curve 18 on a screen 13, the axis of rotation of the galvanometer cutting the screen so that the curve may be seen completely at a single glance. The signals from the aerial 2 pass from slip rings 3, 4 through amplifier 5, rectifier 6, slip rings 7, 8 to the galvanometer coil and light from a source 11 is reflected from a mirror 12 rotating with the galvanometer, on to the galvanometer mirror 10 and thence to the screen 13. The latter mirror is arranged so that in its position of rest the light spot on the screen is displaced from the centre of rotation by an amount equal to the radius of a movable circular portion 24 bearing a scale 17, controlled through shaft 26 and gearing from a compass or drift correcting apparatus 25, or by a number of indicating apparatus working through a differential mechanism. Alternatively the galvanometer may be displaced from the axis of rotation, Fig. 1a, and an additional mirror 12<1> added to the optical system to produce the displacement of the light spot from the centre of the scale 17, the incident beam being preferably parallel to or convergent relative to the axis of rotation. As described, the apparatus produces a modified " figure of eight " polar curve 18, the ambiguity of the readings of which may be removed by adding the signals from an open aerial 19 through coil 20 to the input of amplifier 5, a cardioid curve being thus produced. A mirror 16 may be provided to give a vertical image of the curve and scale. The galvanometer and screen may be removed from the exploring system if the former is rotated synchronously with the latter and several galvanometers 9, Fig. 3, may be fed from the same aerial 2. The synchronization may be effected by driving the aerial 2 by an alternator 22, each galvanometer being rotated by a synchronous motor 33 receiving current from the alternator 22.

Title: Refrigerator door and method of assembling the same
IPC: F25D23/02
Filed: 1956-03-27
Abstract: 810,102. Refrigerators. PHILCO CORPORATION S. A. March 27, 1956 [Sept. 13, 1955], No. 9592/56. Class 29 In a refrigerator having an outer shell provided with an inturned flange and a liner secured to the flange, a gasket being interposed, the side peripheral edges of the liner are resiliently secured to the flange and means are provided for holding the top and bottom of the liner to said flange and for restraining relative movement therebetween unless derived from differential expansion of the shell and liner. As shown in Figs. 2, 4 and 5, the liner 3, which is dished and formed with shelves 4, 5, is provided with peripheral slots 14 parallel to the edges. Resilient clips 20 take through these slots, holes in the flange 22 of gasket 8, and holes 21 in the inturned flange 6 of the outer shell 2. At the corners, the liner has, instead of slots, large holes 18 for the clips. These arrangements permit differential expansion of the liner and shell, the clips moving in the slots 14 or holes 18. At the top, screws 26 secure bars 23 in place, the screws passing through the slots 14, the gasket and holes 21, to clamp the parts in place but yet allowing yielding of the connections. A short clamping bar 28 is mounted at the bottom of the door. To asemble the door, the shell, liner, and gasket are first connected by clips 20 and then bars 23, 28 are lightly secured by screws 26. The door is then twisted, if necessary, about a vertical axis, so that it is complementary to the cabinet front and the screws 26 are tightened up to hold this twist. Even so, the connections still accommodate the stresses due to thermal expansion. The gasket 8 covers all the connecting parts. In a modification, Fig. 6 (not shown), a screw rigidly connects the central top parts of the liner and shell to provide a point of reference, the construction being otherwise the same as that described above. In a further modification, Figs. 7 and 8, a flat inner liner 40 and a shell 41 with an interposed gasket 43 are clamped together at one side by screws 45. At the bottom there is an attachment 47 of which screws 50 pass through slots 52 in in liner and hold a bracket 49 against its underside, the bracket having a tongue 53 received in an aperture 48 in the shell 41. Screws 50 pass through clearance holes in the shell. Tongue 53 thus permits vertical movement of the liner but prevents horizontal movement. A similar arrangement 46 opposite screws 45 permits horizontal movement but prevents vertical movement. To assemble the door, the liner and shell are connected as by clips 55 and screws 45 are tightened. Screws 50 are then lightly applied and the desired twist is given, the screws 50 then being screwed home. The device 47 can be substituted for the bar 28 in the first embodiment. The bar 28 may replace the device 47 in the construction of Figs. 7 and 8.

Title: Laser projector
IPC: H01S3/106
Filed: 1967-03-01
Abstract: 1,111,027. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March, 1967 [24 March, 1966], No. 9621/67. Heading H1C. [Also in Division G2] A phase modulating object 14 such as a hologram is either located within or forms part of a laser resonator, the off-axis radiation 18, 18a, 18b, 20, 20a, 20b produced by the object being projected on to an external viewing screen 34 after passing outside the extremities of a resonator mirror M1. As shown a transparent object formed with a modulated sinusoidal ripple surface 16 is contained within a resonator formed by mirrors M1, M2. The object alternatively may be of uniform thickness and have a non-uniform index of refraction. As the emission from the laser active medium 10 is focussed by lenses L1, L2 on to respective resonator mirrors, the axial modes such as the zero order modes due to the carrier sinusoidal ripple are contained within the resonator. Higher order off-axis modes due to the carrier and its modulation produce output beams focussed, for example, on points 22, 24. Since these points are outside the dimensional limits of small mirror M1 the beams are projected on to the viewing screen by a lens L3. A still smaller mirror M1 is used if the object 14 has no sinusoidal carrier ripple. Lens L1 may be omitted by using a larger mirror M1 spaced further from the object. In a modification the rippled surface of the object may be silvered and replace resonator mirror M2, in which case lens L2 is also omitted.

Title: Accounting machine with arrangement for punching cards
IPC: G06C11/08
Filed: 1958-03-27
Abstract: 844,501. Calculating-machines. KIENZLE APPARATE G.m.b.H. March 27, 1958 [Sept. 13, 1957], No. 9844/58. Class 106 (1). [Also in Groups VIII and XVI] In a key-set accounting-machine, the differential members 3 for setting type-wheels 6 and actuators for totalizers 8, 10 are mechanicallycoupled (12, 13, 14) to punch-selecting members 15 which also position type-wheels 43 arranged for printing on the upper edges of the cards to be punched. The type-wheels 6 co-operate with a platen in a paper carriage 2 carrying members in a frame 22 for controlling the operation of the machine and further members in a frame 23 for controlling the punching mechanism. One of the latter causes an arm 31 to be raised so that when a cam-operated link 36 is actuated, a rod 37 will render the punching mechanism effective. Each selecting-member 15, Fig. 3, is geared to its type-wheel 43 and carries a resilientlymounted hammer 18 which is thus positioned over the appropriate one of a corresponding row of punches 21 so that when a yoke 19 carrying a pressure-plate 20 is lowered by cams, the selected punches will be operated. At the same time, a bar 44 resiliently mounted on the yoke 19 first enters notches in the type-wheels 43 to justify them and then forces them on to the punched card to effect printing. To permit this movement, the type-wheels are carried by arms 46 pivoted at 47. The type-wheels 43 have a cut-away portion 50, adjacent to the record card, in the rest position. The feed of the card is effected by a roller 53, Fig. 5, on a shaft 52 on which is clamped a drum 29, Fig. 6, having stop projections 28 variously spaced around it and the extent of the feed is determined by selecting one of the stops 28 by placing the corresponding one of a set of levers 27 in its path. This is effected by a corresponding control-member in the frame 23 carried by the carriage. A cam 51 carried by the drum 29 positions the pressure-plate 20 over those selecting members 15 which are to be effective and a shoulder 39 of the plate 20 holds the selecting members 15 of those orders which are not to be used in their rest positions. The drum 29 is formed by rings 59 having internal teeth and assembled on a toothed inner drum 57.

IPC: C02F1/58
Filed: 1985-06-03
Abstract: Simultaneous, one step reduction of iron, manganese arsenic and methane contamination from mixed waters of different sources is carried out, in this case after permanganate pretreatment by contacting the water with air over a large surface area. This can be done in open or closed vessels by aeration or by atomizing the water. Oxidn. of contaminants takes place during aeration and methane is liberated. The treated water is allowed then to pass through a sand filter the grains of which are coated with hydrated ion oxide. The emerging effluent contains only a fraction of the original contaminants.
