Title: Improvements relating to hand levers for operating railway points and signals by double wire transmission
IPC: B61L7/02
Filed: 1923-07-06
Abstract: 216,004. Kershaw, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd. July 6, 1923. Hand - levers and hand - gearing; handlevers and handgearing, interlocking.- A hand lever 6 for a double - wire transmission system is provided with a locking piece secured to the ends of the transmission wires 13 which pass over a fixed abutment 14 on the wheel 4, so that if either transmission wire breaks the member 15 is rocked to engage fixed lugs on the frame 19 and to prevent operation of the apparatus. The lever 6 carries a catch bolt connected to the bell crank 11 for operating the tappets. A points lever, Fig. 6, is not directly connected to the wheel 4 as is a signal lever, but, in order to provide means for moving the tappets reversely when the points are trailed through, a spring- controlled sliding pin carried by the lever engages a notch in a projection 23 on the wheel and the catch-rod carries a projection 25 which engages a notch in a flange 26 on the wheel from which it is disengaged if the wheel is forced round independently of the lever and moves the catch rod downwardly and so drives the tappets in a reverse direction from the normal.

Title: Improved injectable iron preparations
Inventor: MICHAEL STEPHEN ERNEST
IPC: C08B37/00
Filed: 1959-05-25
Abstract: An injectable iron preparation is obtained by the reaction of an iron salt such as ferric chloride or ferric nitrate or of ferric oxychloride or of dialysed iron with a synthetic polysaccharide such as polyglucose or polygalactose in an alkaline medium.  The ratio of the weight of the polysaccharde to the weight of iron is preferably from 10-20 : 1.  The polysaccharide may be obtained by heating glucose or galactose with an acid catalyst until the resulting polysaccharide possesses only 5% and 1% respectively of the reducing value of the original sugar.  It is then dissolved in water and the iron salt or dialysed iron added and then sufficient caustic soda solution added to produce a pH of about 11, and then the mixture heated to 100 DEG C. for about two hours.  It is then cooled and methanol, ethanol, or acetone added and the precipitate removed.  The injectable solution may contain 5- 1/4 % of iron.ALSO:An injectable iron preparation is obtained by the reaction of an iron salt such as ferric chloride or ferric nitrate or of ferric oxychloride or of dialysed iron with a synthetic polysaccharide such as polyglucose or polygalactose in an alkaline medium.

Abstract: 813,753. Erecting masts. ATAG-TRUST. June 7, 1956 [June 30, 1955; Oct. 24, 1955], No. 17696/56. Classes 78 (2) and 78 (4). A mast M is formed of sections 51 which are assembled from beneath by platform 38 each section being introduced through an open side of wheeled base frame 14 on to the platform and then raised thereby so that the section is guided by rollers 58 of guide frame 50 and is held therein by pivoted retaining levers 50 engaging slots 57 formed in the section, the section pushing up the previous section and being secured thereto by toggle levers 67 secured to the section and being thus locked to the said previous section automatically by contact with fixed cam projections 70. As shown, each succeeding section is introduced on to platform 38 centred by nose 40 thereof and raised so that it automatically locks itself beneath and to the alreadyformed portion of the mast and is in turn held in the raised position ready for the next section. The next-to-last section (Fig. 15) has two sets of slots respectively 57 and 57a, so that the last section 51e may be partially raised and there secured to permit pedestal 72 to be placed on the platform and to be raised up to the bottom of the mast so that the whole may be lowered on to seat 73. The apparatus is mounted on trailer T stabilized by feet 107 and guy ropes 111, the guide frame 50 being provided with a pivoted door so that the trailer may be moved away to leave the mast free and upstanding. In another embodiment the erecting apparatus is pivoted on the platform of a lorry so that it can be raised into the vertical position by means of a piston and cylinder. The third embodiment of Fig. 21 is employed for triangular mast sections and is shown adapted to erect a mast to be made of small sections 181 and larger sections 180. For this purpose the guide frame 200 is raised by the platform and secured to the top of the base frame 126, the guide frame being provided with runners 171 for guiding the smaller frames and rollers 166 for guiding the larger sections, and there being provided two sets of pivoted retaining levers 155a and 155 and two sets of cam projections 160a and 161 for the smaller and larger sections respectively (corresponding to levers 54 and cam projections 70). Firstly, the smaller sections are elevated, each being guided, retained and locked together. Finally the larger sections are likewise raised until the whole tower is formed, the section shown in Fig. 21 being specially adapted to couple together the smaller with the larger sections. An engine or motor may be provided to work a pump to operate the platform and also to operate a rock drill designed to make the holes for inserting the guy wire anchors in rocky country.

Abstract: 698,662. Attachments for turning. LAYTON, D. A., and ROGERS, W. E. July 17, 1952, No. 18137/52. Class 83 (iii). A tapering and profiling attachment for lathes comprises a base block mounted on the cross-slide, a taper or profile - regulating means mounted on a longitudinal slideway on one end of the base and extending parallel to the lathe bed, an anchoring device for securing the regulating means against axial movement and a tool-carrying block mounted on a slide on the base and extending at rightangles to the longitudinal slide, the tool block carrying the tool at one end and having tracer means at the opposite end to bear against said regulating means when the carriage is traversed to control displacement of the tool block along its slide. The base block 1, Fig. 2, with a dovetailed part 2, is clamped on a lathe carriage at the rear thereof. A shelf 5 integral with the block and extending from the back carries a slide 7 in a guideway parallel to the lathe bed. A guide or profile bar 8 is pivoted to the slide 7 by a screw 11 and may be secured in an angular position relative to the slide by screws 12, Fig. 3. A bracket 13 extends upwardly from one end of the slide 7 and is used to anchor the slide to some fixed part of the lathe. A further slideblock 15 moving in guideways on the upper surface of the base at right-angles to the lathe bed has a " T "-slot 17 for attaching a toolholder. This slide is drawn to the right, Fig. 2, by a spring 20 which maintains a tracer pin 19a against the operative edge of the bar 8. The tracer pin is adjustable in the slide 16 and may be extended or retracted to vary the position of the tool by a knob 22a. Profiles or tapers can be cut according to the form of the operative edge of the bar 8 and its adjustment on the slide 7; the latter remains stationary as the carriage, with the attachment, is traversed along the work.

Abstract: 1,186,784. Detecting icing conditions electrically. HOLLEY CARBURETOR CO. April 20, 1967 [June 23, 1966], No. 18215/67. Heading G1N. Approach of icing conditions at a surface 26, Fig. 1, is detected by sensing its temperature at 24, sensing the temperature of a second surface 12 at 14, and maintaining a predetermined difference between them by means of a cooler unit 12, condensation on the second surface being detected by a sensor 16 and an output from a logic unit 40 being obtained at 42 when both condensation at 16 is detected, and the temperature at 24 of the first surface is below freezing point. The output 42 may operate at 44 a visual alarm, or a heating device to offset the icing, and the predetermined difference between the surfaces<SP>1</SP> temperatures may be varied for different applications. The second surface is protected by a cover from precipitation such as rain; and to avoid icing of surface 26 due to subzero temperatures occurring during or after precipitation, as opposed to condensation, a pair of additional resistive probes 21, 22 is mounted in the surface 26. One 21 is heated and the other unheated, so that if ice forms, a significant resistance difference arises between them, and the unit 40 is operated to energize the alarm or heater 44. In a modification, freezing inside a pipe (52, Fig. 2, not shown) is prevented by a similar arrangement of test surface (26) in the pipe and controlled surface (12); in this case, however, the atmosphere surrounding the test surface is pumped (54) over the controlled surface via ducts (58, 60).
