Title: Improvements in suspensions for casement windows
IPC: E06B7/16
Filed: 1932-03-22
Abstract: 399,486. Hinges ; fastenings. BARWINKEL, P., 175, Auf der Reide, D³sseldorf, Germany. March 22, 1932, No. 8508. [Classes 44 and 65 (ii).] The sash frame of a casement window is so mounted on its hinges that it is capable of lateral displacement in its own plane when in the closed position, and when so displaced is clamped against the window frame by means of co-operating wedge-blocks fitted to the two frames. According to one construction, the sash frame 6, Figs. 4, 5 and 6, is provided with hinge eyes 7, 8, 9 mounted on eccentrics 12 on a vertical rotatable shaft 14. This shaft also carries eccentrics 13 which pass through hinge eyes 11 on the window frame 1, these eccentrics being diametrically opposed to the eccentrics 12. Thus by rotating the shaft by means of a handle 15 pivoted thereto, the sash frame is displaced laterally in its own plane. Wedge-blocks 20 are fitted to the frames 6, 1, and further wedge-blocks 19 are attached to the frame 6, whereby this lateral displacement effects the clamping of the frames. The sash is locked in this position by the handle 15 which engages with a fixed lug 17 on the hinge eye 8. Locking of the sash frame in any desired open position is effected by the engagement of a brake element 22 thereon with the hinge eye 11 and by the engagement of the handle with a lug 18 on the hinge eye 8. In a modification, an upper and lower casement are slidably mounted in guides 35, Fig. 9, of the window frame. Each sash is carried by a slide 23 connected by arms 24 to collars 37 which are mounted on eccentrics carried by a vertical rotatable rod 29. These eccentrics are diametrically opposed to eccentrics 26 which are embraced by collars 25 connected by hinges 27 to the casement. Lateral displacement of the sash frames is effected by a handle 30 and clamping is effected by wedge-blocks 31, 32. To enable one sash to slide past the other, one sash is locked in the open position by bring- ing a slot 34 in the hinge into engagement with a lug 33 on the collar 37.

A circle b on the card a is provided with four sets of continuous logarithmic scales each extending over a quadrant and representing respectively units, tens, hundreds, and thousands of lumens, portions of the units and thousands scales overlapping. On the disk d are formed scales e, f graduated to represent respectively the area of the rectangle to be illuminated and the side of the corresponding mean square. An aperture g, provided with reading arrows p, q, is formed in the disk h through which the scales e, f are read. Also carried by the disk d are scales r, w, the former being adapted to determine the height of the lighting units above the working plane and the latter to determine the drop from the ceiling in the case of indirect lighting. The scale w is viewed through an aperture x and the scale r through apertures s, t, v in the disk h corresponding to focusing, intensive, and extensive types of reflectors. A scale k on the card a is graduated in accordance with the optical properties of different types of glass ware, only the graduations necessary in practice being shown. Such a scale is determined from the formula L = I x A Î <1>k where L = the intensity per lamp in lumens, I = the average intensity of illumination desired in foot candles, and K = the utilization efficiency. In opera tion, an arrow m carried by the disk d is placed opposite the type of reflector employed on the scale k, the disk h is rotated 27 to bring the arrow p or q opposite the area to be lighted or the mean side of the square corresponding thereto, and the number of lumens required is read off on the scale b opposite the graduation on the scale r corresponding to the intensity of illumination in foot candles. The invention may be applied to slide-rules other than circular.

Title: Improvements in spring balances for determining specific gravity
IPC: G01N9/08
Filed: 1953-03-31
Abstract: 724,579. Specific-gravity estimating-apparatus. UNITED STATES RUBBER CO. March 31, 1953 [June 20, 1952], No. 8857/53. Class 97 (3). A spring balance for determining the specific gravity of a sample comprises a freely suspended spring and means for supporting the sample from the free end of the spring, a first graduated scale secured to the free end of the spring and movable with the sample supporting means, and a second normally stationary scale mounted in parallel relationship to the path of movement of the first scale. As shown in Fig. 1, the balance has a stand having an upright 11 and a horizontal arm 12 of which springs 15, 16 are suspended, these springs being joined by a bar 19 which carries a scale 20 having a hook 21 for supporting a sample S. A second scale 24 is adjustably mounted at 26, 27 on a rigid support 25 carried by the arm 12. A pointer 29 is slidable along the stand upright 11 and the latter also carries slidably a platform 31 for a beaker 36 of water. The scales 20, 24 have graduations W and A respectively which are used in determining the specific gravity of a sample of unknown volume. Firstly, scale 24 is adjusted until its zero coincides with that of scale 20 and then sample S is suspended in air from scale 20, pointer 29 being moved until it is aligned with the zero of the W graduations ; the weight of the sample in air is thus given by the reading on the A graduations. Platform 31 is then raised to immerse the sample in water and a reading is taken on the W graduations/this reading giving the apparent loss in weight of the sample in water. The ratio of these readings give the specific gravity. Scale 24 has also graduations G which represent specific gravities of samples of standard volume and scale 20 has further graduations C giving correction factors which must be added to or subtracted from the G reading to compensate for the difference between the volume of the sample and the standard volume.

Abstract: 231,891. British Thomson-Houston Co., Ltd., (Assignees of Whiting, M. A.). April 3, 1924, [Convention date]. Exciting; pole-pieces, cores, and yokes. - In the control of machines such as lift motors connected to generators according to the Ward Leonard system, an exciter generator E is arranged to strengthen the field F of the working generator G according to the current traversing the circuit of the working motor M. The exciter field winding Ef is in series in the working circuit, and constricted iron parts and air gaps of the exciter are so designed that the flux increases approximately with the working current up to a safe maximum load and thereafter becomes saturated. The effect is that the speed of hoisting remains approximately constant up to the given load and afterwards slows considerably as the load increases further. The excitation due to the machine E is normally compounded with excitation due to a, constant-potential supply from the conductors 10. Arrangements may be added whereby the relative importance of the two components can be varied. Full details of suitable control schemes and numerical examples of exciter fluxes calculated for stated characteristics are given in the Specification.
