Title: Improvements in stays for doors and windows
IPC: E05C17/32
Filed: 1934-11-22
Abstract: 447,548. Stays. BANKS, J. H., and BANKS, G. H., (trading as BANKS & SONS, J.), Willenhall, Staffordshire. Nov. 22, 1934, No. 33581. [Class 65 (i)] A door or like stay comprises two main members pivoted respectively to the door and frame and pivotally connected together by a pin-and-slot joint so that the stay, when opened out approximately to a straight line, can be slightly lengthened or shortened against the force of a spring to release means which secure the stay in the opened-out position. In one form, Fig. 3, the members C, D are connected by a pin E on the former engaging a slot in the latter, the pin being pressed to one end of the slot by a spring f<3> acting on a member F which slides on member D and engages the pin E. As the stay straightens on opening the door, the curved end of member D presses back a spring-pressed catch G, pivoted on the member C, and presses a lever H against a stop c<5> to limit the opening, in which position the catch G springs back to hold member D. Further opening extends the stay against the action of spring f<3> until a notch d<3> in member D engages the end of lever H, which carries the end of the member D clear of catch G in the closing movement. In another form, Fig. 6, the pivot pin E is carried by member D and engages a slot in member C, which carries a sliding spring- pressed member N engaging the pin E and having a nose to press back and be engaged by a spring-pressed detent G on member D. In this case the initial closing movement forces member C forwards to press G back clear of the end of N.

Title: Method and apparatus of chemical photometric spot test analysis
IPC: G01N21/76
Filed: 1975-08-15
Abstract: 1522965 Chemical spot test photometry; chemical spot test DAMON CORP 15 Aug 1975 [19 Aug 1974] 34011/75 Headings G1A and G1B A chemical spot test apparatus comprises a porous or fibrous medium with sample and reagents at a site therein, in optically thin concentrations, means of producing an incident beam of electromagnetic radiation, the resulting emergent radiation having a parameter which changes with concentration of a reaction component and means for detecting the parameter providing a measure of change in this concentration. Optically this is defined by the absorbance of electromagnetic radiation by the concentration being measured being less than 0À2. The embodiment of Fig. 4 comprises fluorimeter 30 and press 32. The sample is deposited on dry fibrous sheet 36 by pipette 40. When press head 51 is lowered it forces some of the small molecule fraction through ultrafiltration membrane 38 to dry fibrous reagent bearing sheet 34. Base 42 has passages 48 and 50 making equal angles with sheet 34, of which the part under foot member 52 is illuminated by lamp 44 through filter 54 and platten 46. These are reference detector 56, fluorescence detector 58, lens 60 and filters 62, 64, 66 of low fluorescence. The embodiment of Fig. 6 (not shown) has a continuous paper strip carrier (72) resting on a flat surface. A transparent film (76) is wrapped around it to enclose the reactants and prevent evaporation. A heating element (92) prevents condensation. Photometers other than fluorimetric may be used instead. In the embodiment of Fig. 7 (not shown), the carrier (102) is located between lower (96) and upper (108) housings which both have light passages. Thus both fluorescence and absorption can be measured. The reactant bearing disc (94) is in an enclosure sealed by windows (104 and 98) and gasket (100). The reaction site may be an unbounded portion of a fibrous or porous medium. Non wicking cellulose fibres are preferred. The site is pre-treated with high molecular weight crystalline ethylene polymer. The reagents are applied in a sequence corresponding to molecular size in a repeatable spatial distribution and not saturating the site. The reaction product concentration is obtained from the difference of measurements at two times or measurements are taken at intervals. The termination of spreading occurs prior to the completion of sensing and the linear rate of change is measured. A repeatable state of compression is maintained.

Abstract: 362,130. Winding tuft yarn spools for looms. ADAM, Ltd., W. & R. R. and YOUNG, H., Greenhill Works, Birmingham Road, Kidderminster, Worcestershire. Nov. 14, 1930, No. 34261. [Class 142 (iv).] In machines for winding yarns side by side upon spools used in Axminster looms &c., the spool is rotated frictionally by lower rollers 8 mounted in fixed bearings and is pressed upon by an upper roller 6 carried by a frame 4, hinged at 5 and carried by vertically slidable bars 3 mounted in guides 2. The frame is normally kept from tilting by a roller 10a on a locking piece 10 thereon engaging an edge of the fixed machine frame, whilst the frame is held down by a spring 18 and by a link 11 connected to an arm 12 on a counterweighted shaft 13. As the spool fills, the frame 4 rises and when the spool attains the desired diameter, the arm 12 engages a roller or pin &c. 17 in a slot 16 in a latch lever 14, thereby raising the lever and disengaging it from a groove or recesses in a latch bolt 22. A spring acting on a collar on this bolt thereupon moves it axially and displaces a starting shaft whereby a clutch is operated to stop the machine The locking piece 10 at this time still engages the side of the machine frame, and a hand gear 34 is operated whereby an edge cam on a wheel 35 is caused to raise the sliding bars 3 and hinged frame to enable this to be swung over by a handle 9 to release the roll 6 from the yarn spool to enable this to be removed. The latch bolt 22 is centrally bored for telescopic engagement with the starting shaft, which is connected by a link to a foot treadle. This can be operated to stop the machine in case of yarn breakage &c., the latch bolt 22 being still held in operative position by the lever 14.

Abstract: 343,032. Cycle spring frames. ALMACK, J. P., 37, Gordon Road, Ealing, London. Nov. 11, 1929, No. 34385. [Class 136 (iii).] In a spring suspension for the rear wheel of a motor or other bicycle, of the type in which the wheel spindle is carried by pistons mounted between compression springs in longitudinally-slotted cylinders, improved means are provided for securing the pistons to the spindle, for mounting the cylinders on the cycle frame, and for mounting the springs in the cylinders and damping their action. Each piston 27, 28 is mounted between compression springs 25, 30, and is secured to the end of the wheel spindle 50 by means of a sleeve nut 34 passing through it and through opposite longitudinal slots 33 in the cylinder 11, which is attached to the fork lug by means of a lug 12 and a bolt, and to an upper part of the cycle frame, such as the junction of the back stay and seat tube, by means of a torque stay connected to a top lug 19. The sleeve nut 34 is provided with an enlarged outer portion 36 forming a shoulder to bear against a flat on the outer side of the piston, and a washer 37 on the inner part of the sleeve nut 34 passes through the inner slot -33 in the cylinder 11 to bear against a flat on the inner side of the piston, a distance piece 38 for centralizing the wheel being interposed between the washer 37 and the cone or locking-nut 40 of the wheel hub. In order to prevent the escape of lubricant through the slots 33, the washer 37 carries a metal plate 42 fitting the outer wall of the cylinder 11, and a similar plate 44 covers the outer slot, the plates being lined with felt &c., or, as shown in the case of the outer plate 44, with frictional material to form a vibration-damper, which is adjusted by means of a hand-wheel 47 and a spring washer 46. The upper spring 30 is stronger than the lower spring 25, and may comprise two concentric springs. A rubber disc 32 in the upper end of the cylinder 11 prevents jarring if the upper spring becomes fully compressed. The piston movement may be hydraulically damped by lubricant contained in the cylinder on both sides of the piston, the working surfaces of the piston or cylinder being formed with one or more passages, such as a helical groove, for the passage of the lubricant from one side of the piston to the other. The cylinder 11 may be provided with lugs such as 56 for the attachment of a mudguard stay, lifting handle, stand, &c. The spring suspension may be adjusted by angular adjustment of the cylinders 11 about their attachment to the fork lugs.
