Title: Improvements in or relating to telecommunication dialling control apparatus
IPC: H04M1/31
Filed: 1959-03-26
Abstract: 912,543. Sets. DEUTSCHE FERNSPRECHER G.m.b.H. March 26, 1959 [March 27, 1958], No. 10580/59. Class 40 (4). A single detachable impulse transmitting unit which can be plugged into a telephone set casing has projecting terminals 11, Figs. 1, 2, which terminals can be engaged with co-operating terminals of the plug-and-socket type within the casing. In addition to dialling switch contacts (not shown) the unit has contacts 5, 6, 7 for preparing calling circuits, these additional contacts being actuated by a pin 1 passing through a main shaft 18 journalled in a base-plate 23 and operable by the weight of the receiver or removal of a cover. The dialling contacts and additional contacts 5, 6, 7 are secured to the base-plate 23. The dialling contacts are operated through a gear-wheel 19 secured to the main shaft 18 by rotation of a selector disc 22 also secured to the main shaft 18. The pin 1 is slidable axially along the main shaft 18 and has secured at its upper end a push-button 2 urged by a spring 3 against a stop disc 4 on the selector disc. The dialling switch contacts and additional contacts may be housed in a hood 13. In a modification the function of the push-button is performed by the selector disc 14, Fig. 3. The selector disc has a pin 21 on its underside which co-operates with a hole 20 in the base-plate 23 permitting downward movement only when the selector disc 14 is in its rest position. The mounting of the selector disc 14 on the main shaft may be such as to provide increased frictional resistance to axial movement of the disc when the disc is rotated from its rest position.

Abstract: 342,602. Fluid - pressure brakes. HILDEBRAND, W., 3, Ulmenplatz, Lichterfelde, Berlin. April 4, 1930, No. 10792. Convention date, April 26, 1929. [Class 103 (i).] Relates to fluid-pressure brakes of the kind described in Specification 318,940, [Class 103 (i), Brakes &c.], and comprising a primary control valve st1 controlled by the pressure in the train-pipe L and also that in an auxiliary reservoir B and a secondary control valve st2 controlled by the pressures in the auxiliary reservoir B, the brake cylinder C and that in a chamber A and including a second brake cylinder supply reservoir R supplied through a throttling device D. To avoid the possibility of the valves returning to the application position after the release operation due to local fall of the train-pipe pressure by reason of the continued supply of the second reservoir R, this reservoir instead of being directly connected to the train-pipe is arranged to be supplied only when the primary control valve st1 is in the release position. For this purpose the reservoir R may as shown be connected to the valve chamber of the valve st1 with the interposition of a non-return valve E or to the rear of the piston chamber of this valve by a pipe F or through a duct controlled by the slide valve S which is only open in the release position of the slide valve.

Abstract: 1,204,992. Valve-controlled filters. PUREX CORP. Ltd. 28 Feb., 1969 [10 Sept., 1968], No. 10998/69. Heading BID. [Also in Division F2] During normal filtration flow, water (e.g. from a swimming pool) enters port 29, passes through conduit 51 of a plug valve and hence through a filter element 11; filtrate collected by conduits 22 enters a manifold chamber 20 and is discharged at 28. To backwash, a handle 46 is rotated to put conduit 51 in contact with a wasteport 30 and to cause the plug to block outlet 28; hence water issues from conduits 22, backwashes the filter, and is discharged via conduit 51 and port 30. The valve unit 12 is formed in upper and lower halves which clamp housing 10 between them. Filter element 11 may be a sand bed.

[Class 132 (iii)] A method of laying model railway track includes the step of moulding the jaws 2 of a relatively soft metal chair 1 on to a length of rail R seated in said chair by causing the metal of the jaws to flow, while in the.cold state, into intimate contact with the lower portion F of the rail while limiting the flow of the metal in the direction of the running surface of the rail to an extent such as to leave clearance between the wheel flanges and said jaws on completion of the moulding operation. The sleeper S upon which the chair rests is provided with holes through which spaced rivet elements 4 formed beneath the chair pass and are then flattened to form rivet heads 5. The sleepers may be made of any suitable material, insulating or not, and the chairs may be used in the laying-out of points and crossovers as well as straight and curved lengths of track.

Title: Improvements in and relating to raking apparatus for sewage screens
IPC: E02B8/02
Filed: 1944-06-09
Abstract: 585,472. Strainers. HARVEY, J. B., and ADAMS-HYDRAULICS, Ltd. June 9, 1944, No. 11047. [Class 46] [Also in Group XXXVII] In apparatus for cleaning sewage screens of the kind in which a rake is drawn along the bars of a substantially vertical screen, the reciprocation of the rake is effected by means of a reversible electric motor which is controlled by means of switches actuated by tappets movable with the rake, and also by means of a time switch, so that the rake is brought to rest only in the uppermost position. As shown, a rake frame 22 provided with teeth 23 for entering between the bars of a screen 24 is carried by chains 16, which pass over sprocket wheels 14, and under sprocket wheels 18 with a counterweight 21, and are connected to a transverse member. The sprockets 14 are adapted to be driven, through a slipping clutch, by a reversible electric motor. Switches 66, 74 are normally closed but the switch 66 is opened by means of a tappet on the chain 16 as the rake approached its uppermost position and the switch 74 is opened by means of another tappet as the rake approaches its lowermost position. These switches co-operate with a time switch (see Group XXXVII) whereby the motor is reversed, and stopped only when the rake is uppermost. The sewage is collected in a chamber 25 provided with channels 28 in which slide guide pins 29 on the rake frame 22, the rake being withdrawn from the screen during its downward movement. As the frame approaches the uppermost position tappets thereon engage levers 42 connected to counterweighted arms 36 which support a frame 35 carrying teeth 34 whereby the teeth are operated to detach screenings from the frame 22 and deliver them to a trough 47. Alternatively, the cleaning members may be mounted on a rotary shaft driven by a toothed rack and pinion from the rake frame.

[Class 100 (iv)] A shorthand writing - machine which is especially applicable for printing phonetic contractions according to a conventional system, such as the Gregg system, is constructed with a keyboard which controls the position of a number of type sectors 13, each fitted with a number of type 13d which print in conjunction with a platen 18 and ink-ribbon 17 on a narrow strip A, Fig. 4, the type being arranged vertically, but on edge, so that the typed character impressions are arranged in upright relation one above the other, readable in single rows in continuity transversely of the paper strip when produced .by the actuation of several type members simultaneously. As shown, there are ten type levers 2 pivoted about a common journal pin 4a and separated by guide members 5, 6. Each lever 2 is fitted with four keys 9 normally raised by coiled springs 10. The type sectors 13 are fitted with four types and.these are set by a link 14 connected to a lever 3 which is pivoted also about the pin 4a and acted upon by the keys to set the type prior to further depression of the keys to cause the impression stroke which is effected by a link 15 connected to a lever 16 pivoted to a fixed pivot 16a and connected by a pivot 13a to the type sector. The spacing-lever 8 is depressable by a member 7 and is also pivoted to the pin 4a, and motion is transmitted from the lever 8 to a spring- controlled stirrup member 20, Fig. 3 (not shown), which operates a pawl for operating a ratchet wheel on the shaft of the platen 18 with which coacts a roller 19 for advancing the strip A. The spacing-stirrup is also operated at each depression of a key lever. The levers 2 are normally raised by springs 11, and the ends 2c of the levers are formed of light plastic material screwed to the pivoted ends of the levers. The key 9 near the spacing member, when depressed, has no action on, the adjacent lever 3.
