Title: Method for chemically treating vulcanized oils, and products so obtained
Filed: 1945-08-07
Abstract: In a two-stage process for the manufacture of vulcanized esters of polyhydroxy alcohols and unsaturated fatty acids the esters are first hot vulcanized to a lesser degree of vulcanization than would obtain in the normal single stage process and then treated with a basic chemical.  The prolonged heat treatment required when fatty oils are converted into very viscous or into solid products of low acetone solubility solely by hot vulcanization with consequent adverse effect on the colour and other qualities of the product is thus avoided. The esters used as raw material may include unsaturated natural fatty oils.  Accelerators, activators, modifiers or fillers may be added to the mixture of oil and vulcanizing agent before heating.  The degree of vulcanization may be such that the oil is rendered somewhat viscous, very viscous or solid, and the subsequent treatment with the basic chemical is continued until the final product is substantially thickened, solidified, or substantially hardened respectively.  The basic chemical may be a basic nitrogen compound, e.g., ammonia, or a basic ammonia derivative or compound; a basic oxygen-free nitrogen compound, e.g., a basic organic amine or derivative thereof. Alternatively it may be a compound containing an -OH group, e.g., a hydroxide of an alkali metal or of an alkaline earth metal.  The treatment with a basic chemical cannot be applied to cold vulcanized oils, e.g., oils vulcanized with sulphur chloride, since such vulcanizates react in a different way.  In an example 100 parts of rape oil are heated with 17 parts of sulphur at 260-280 DEG F. with slow agitation until a cooled sample shows no separation of sulphur from the mixture.  The resulting viscous oil is then mixed with 1/2 per cent. of piperazine, and allowed to stand at room temperature, when it is converted into a solid gel.  In a second example 100 parts of rape oil are heated with 20 parts of sulphur to 260-280 DEG F as above, the resulting viscous oil applied as a thin coating to a metal article and the latter placed in a closed vessel which is first evacuated and then filled with gaseous ammonia.  After 20 minutes the coating has been converted into a solid protective film. Specification 453,921 is referred to.

Title: Improvements in radio navigational aids
IPC: G01S1/02
Filed: 1944-10-25
Abstract: 608,220. Radio navigation. PHILIPS BALHAM WORKS, Ltd., (formerly RADIO TRANSMISSION EQUIPMENT, Ltd.), and BAILEY, C. E. G. Oct. 25, 1944, No. 20806. [Class 40 (vii)] The course line in a radio navigation system is defined by the overlapping of two radiation patterns of carrier frequency radiation', each pattern being modulated by different periodic waves, the sign of one of which is reversed about the course and the period of one of which is an integral multiple of the period of the other. In a first embodiment, the modulation waves are sinusoidal and the period of the wave which is not reversed about the course is three times that of the wave which is (a and b, Fig. 1). On one side of the course, the waves add to form a combined waveform as indicated at 1c and on the other side the combined waveform is such as at 1d; on the course only the modulation 1a can be received. In a suitable receiver the modulation signals are applied to a peak rectifier 3 followed by a 2/# attenuator 4 and also to a mean rectifier 6. The outputs of the attenuator 4 and rectifier 6 are applied in opposition to centre zero meter 5 which reads zero on the course and indicates deviations to either side thereof. In a second embodiment, the modulations are of rectangular waveform and that which is not reversed about the course is maintained alternately for equal times in each period at two different amplitudes (Fig. 2a) and that which is reversed is maintained alternately at two amplitudes, each substantially different from half the period of the first modulation, and has a period half that of the first modulation (Fig. 2b). The resultant of the two signals on the two sides of the beacon axis are shown in Figs. 2c and 2d. In a suitable receiver, the modulation signals are passed through a filter 7 to eliminate the steady components thereof and then applied to two halfwave peak rectifiers 8 and 9 with their inputs and outputs in opposition. The opposed outputs are fed to a central zero meter 10 providing the same indications as are provided by meter 5 of the first embodiment. The course defined by the system may be fixed or may be rotated in azimuth to form a rotary beacon and a modification of the waveform described in Specification 580,985 to give a system similar to the second embodiment above would enable the receiver indicating means described therein to be combined with automatic steering means for which the present system is particularly suitable. It is stated that the phase relationship between the modulations may be important.

Abstract: 317,071. Halpin, T. S. Aug. 10, 1928, [Convention date]. Controlling stopping-positions of rotating discs; prize-delivery mechanism; exhibiting moving figures and the like.-Relates to sales machines in which a number of wheels are set spinning after the insertion of a coin, and a coin or premium check &c. is delivered automatically if the wheels stop in certain positions. In order to make the gaining of a premium dependent entirely upon skill, the premium-discharge mechanism is normally locked, and a catch device is moved to allow such release only when handcontrols for applying variable braking force to the spinning wheels are brought into operation. As shown in sectional plan in Fig. 2, the premium-discharge mechanism comprises delivery slides 5, locked by a catch 21 on a lever 20 which is held in the locking position by a latch 19. Time-controlled mechanism (not shown) moves the lever 20 to unlock the slides 5 and if the latch 19 has been moved away from the end of the lever which prevents release of the locking mechanism 20, a premium is delivered if the discs stop in suitable positions. The latch 19 is pivoted on the frame of the machine, and is connected by a link -18 with a lever 17, as shown in Fig. 4. The lever 17 is supported by a bar 15 resting upon handlevers 10 by which the operator attempts to stop each of the spinning discs in the correct position. The lever 17 is lowered, to move the latch 19 away from the lever 20, when all of the control levers 10 are depressed by the operator. Each lever 10 carries a spring-suspended roller to engage a star-wheel mounted on one of the spinning wheels.

Title: Improvements in or relating to electric horns
IPC: G10K9/15
Filed: 1929-07-08
Abstract: 336,228. Pollak, J. E., (Greiner, M.). July 8, 1929. Diaphragms; magnetic instruments.-An electric horn comprises a diaphragm 12, Fig. 1, a mass 28 attached to the centre, means for vibrating the system of the diaphragm and mass, and a weight 34 connected by a spring 33 to the mass 28, the weight vibrating perpendicular to the diaphragm and having a natural frequency of vibration small compared to the natural frequency of vibration of the diaphragm system. The mass 28 is mounted on a spring 30 clamped at 32 and is vibrated by pole-pieces' 19, Fig. 2, encircled with coils 20 and mounted on an iron core 17 held by a clamp 16 on a bridge 15. The circuit to the coils contains an interrupter operated by the oscillating system and consisting of contacts 40, Fig. 2, carried on springs 42, 38 held between insulating blocks 37, by screws 39, Fig. 3, on to an arm 36. The springs 38, 42 normally bear on the strip 33 but on the upward movement of the armature, the springs 38, 42 lift until stopped by an adjustable stop 43, Fig. 2, and a rivet 44, Fig. 1 respectively, when contact is broken. At the commencement of vibration the mass 34 having a low natural frequency aids the diaphragm to reach that frequency. The diaphragm then tends to reach its own high natural frequency, the vibration of the mass 34 being retarded by a damping strip 45 contacting slightly with it. When the diaphragm has attained its natural frequency, the mass 34 is unable to follow its vibrations and so remains practically stationary and the spring 33 acts as spring 30 in providing additional restoring force. It is stated that the co-ordination of the interrupter with the vibrating system allows the contacts to open only when the armature has nearly reached the end of its stroke and that the coils 20 may therefore have a higher resistance, so giving an economical consumption of current for a given power of oscillation. In the alternative form, Fig. 7, the armature 128 is connected by spring 133 to two weights 134 damped by spring blades 145. The armature 28. Fig. 1, is connected to the diaphragm 12 through the intermediary of two washers 27 of a material different from the material of the diaphragm, e.g. bronze, to reduce the destructive effects of friction. The diaphragm is of steel or bronze and when unmounted, Fig. 4, has a wavy periphery so that on clamping the diaphragm is tensioned. It is also corrugated concentrically, to give flexibility, leaving a plane central area. It may be 4¢ inches in diameter and 0.008 inch in thickness for hardened Swedish steel. The diaphragm operates into a funnel 10 with its interior preferably unobstructed. The horn is mounted on resilient elastic spring blades 46. Figs. 1, 3, so that the entire structure is capable of oscillation parallel to the oscillation of the diaphragm 12.
