Abstract: 465,710. Illuminated clocks. NATIONALE TELEPHON-UND TELEGRAPHENWERKE GES. Sept. 21, 1936, No. 25657. Convention date, Sept. 20, 1935. [Class 139] A clock is provided with a hand M of translucent material (colourless or coloured), the axis of rotation of which is surrounded by a chamber K of opaque material closed at the end situated in front of the dial B and internally illuminated by a source of light L situated near the said axis and in which the hand projects, at C, into the chamber K and has its rear surface made reflecting (by a white paper reflector F) so that the light received by the end C is used to illuminate the hand without illuminating the dial B. The rear face R of the hand is roughened and the outer third of the rear face is curved to radiate a greater part of the light so that the distribution throughout the hand is uniform. The chapters S are translucent rectangular prisms illuminated from behind the dial by the lamp L. In the section of the hand shown in Fig. 3 the colourless hand M1 is enclosed by a coloured translucent member M2. The surface of the hand may be coated with a coloured lacquer. In Fig. 4 the chamber K is split into halves, the front half K1 for the arbor A of the minute hand M and the rear half K2 for the sleeve D of the hour hand H. Sleeve D is connected to part K2 by a spider E so that a number of electric lamps L may serve for both hands.

Abstract: 986,483. Baling presses. COURTAULDS Ltd. July 26, 1961 [July 27, 1960], No. 26074/60. Heading B5F. [Also in Division B8C] A method of compressing material, e.g. synthetic fibres, comprises placing the material in a bottomless first container 1 on a stand 4, enclosing the container in a rigid second bottomless container 5, removing the first container without the material or stand and compressing the material in the second container on the stand to form a bale. A glass fibre container 1 with flanges 3 is placed on a stand 4 which already has a sheet of wrapping material 12, such as hessian, over it, and is filled. The container 1 and stand 4 are moved into a second stronger container 5 by opening a side which is then closed.

Title: Improvements in and relating to methods of increasing the permeability of silicon iron
IPC: C22C38/02
Filed: 1936-09-25
Abstract: In a method of increasing the permeability and lowering the coefficient of loss of commercial silicon iron the ingot is first hot rolled to from 4 to 9 times its final thickness at a temperature which gradually decreases and which during the early stages is from 1000 to 1200 DEG  C., and during the later stages is from 700 to 1000 DEG  C. is then quickly cooled or quenched from a temperature of from 900 to 1100 DEG  C. is next cold rolled to the final thickness and is finally annealed in a non-oxidizing atmosphere for 2 to 12 hours at a temperature of from 1050 to 1350 DEG  C.  In a modification, the ingot is hot rolled to about 8 to 20 times its final thickness, is then quickly cooled or quenched from a temperature which falls gradually from 850 to 450 DEG  C. is then cold rolled to its final thickness and is finally annealed for from 2 to 12 hours at a temperature of from 1050 to 1350 DEG  C. After being hot rolled the material may be annealed for one hour at 1000 DEG  C and then quenched in water.  The material preferably contains from 3 to 5 per cent. of silicon and may also contain small quantities of other constituents such as manganese and aluminium, and in an example containing 3,5 per cent. of silicon and 0,15 per cent of manganese the ingot is rolled to a thickness of 5 mm. at a temperature of 1100 DEG  C. and is then rolled down from 5 mm. to 2 mm. at a temperature of 850 DEG  C. with repeated annealings.  The material is then heated for one hour at 1000 DEG  C. is next quenched in water, then cold rolled to a final thickness of 0,35 mm. and is finally annealed in hydrogen at 1250 DEG  C.  In another example, iron containing 3,5 per cent of silicon, 0,1 per cent of manganese and 0,1 per cent of aluminium is treated in the same way, the first example giving an initial permeability of 1,900, a maximum permeability of 35,500 and a coefficient of loss of 0,57 watts per kilogram whilst the second example gives figures of 1700, 23,300 and 0,57 respectively.

Title: Improvements in and relating to apparatus for testing working materials or constructional parts
IPC: G01N3/34
Filed: 1936-10-05
Abstract: 464,082. Testing physical qualities of materials. SCHENCK EISENGIESSEREI U. MASCHINENFABRIK DARMSTADT GES., C. Oct. 5, 1936, No. 27026. Convention date, Oct. 23, 1935. [Class 106 (ii)] An exciting means consisting of one or more rotating unbalanced masses is mounted on the free end of a spring which resiliently connects them to the body under test, and the masses are rotated at or near a speed corresponding to the natural frequency of the whole system. In the form shown in Fig. 1, the spring a is clamped in a fixed support b and loaded by a mass c containing the unbalanced masses d. The test bar e is clamped at one end to the spring and at the other to a fixture. The spring a, bar e, and masses c, d form an oscillating system the resiliency of which is essentially determined by the spring a. In the form shown in Fig. 2, one end of the specimen g is clamped to a fixture and the other at h to the spring i to the ends of which are secured masses k, l. Instead of one spring, two each secured to the end of the bar and lying in the same line may be used. The mass k is provided with a rotating mass m having unbalanced weights. If the mass l and arm i are properly chosen, the masses k, l will oscillate in substantially the same phase, and the specimen stressed alternately in tension and compression with large forces. A spring u arranged between the clamp and a fixture may provide a static stress. Rotating masses like k may be used at each end of the spring. To avoid disturbances to the foundation, the installation may be mounted on weak springs. In this case the test body is arranged horizontally and two similar clamping devices rest on a number of vertical springs, the clamp f being connected to a large mass resiliently mounted. It is possible to dispense with the large mass and load the body similarly at each end, the phase between the oscillating means being adjusted to produce the desired stress. Static stresses may be applied by springs. Fig. 3 shows a form for a bending test, the specimen o being fixed at one end and secured at the other to a spring q carrying a mass r and rotating unbalanced mass s. Static stress is applied by a spring t. Torsional stress may be examined as in Fig. 4, which is similar to Fig. 3, except that the spring u and masses x, y have been turned through a right-angle.
