Patent GB-660972-A (GB)
Title: Improvements in the production of crotonaldehyde
IPC: C07C45/72
Filed: 1949-10-20
Abstract: Crotonaldehyde is made by incompletely aldolizing acetaldehyde with an alkaline substance in the presence of an amount of water substantially below that of acetaldehyde and directly subjecting the aldol-acetaldehyde mixture to the action of an aqueous electrolyte solution maintained at pH 2-7 and at a temperature above the boiling-point of acetaldehyde, preferably while introducing into said solution an amount of a non-volatile mineral acid sufficient to neutralize the alkaline substance present in the aldol-acetaldehyde mixture.  Acetaldehyde is distilled from the electrolytic solution and crotonaldehyde drawn off in liquid form.  Preferably acetaldehyde is led together with 1 to 10 per cent of a 5-15 per cent aqueous sodium or other alkali metal hydroxide through a vessel at below 30 DEG  C. to effect less than 60 but more than 30 per cent conversion to aldol and the mixture crotonized at 60-110 DEG  C., under normal pressure.  Crotonizing agents are water-soluble substances which in solution yield hydrogen ions, e.g. non-volatile mineral acids such as sulphuric or phosphoric acid or acid salts such as sodium bisulphate or monosodium-phosphate.  Mixtures of such salts with free acids exerting a buffering action may be used.  Concentrations indicated are from 2-40, preferably 15-35 per cent.  To maintain the specified pH range free acid is introduced with the crude aldol into the electrolyte.  The crude aldol may be added to a part of the electrolyte and the mixture neutralized and added to the bulk of the electrolyte.  The acid salt used preferably corresponds to that obtained by neutralizing the alkalinity of the crude aldol. In an example aldolization to an extent of about 50 per cent is effected with 10 per cent sodium hydroxide and crotonization by pouring the aldol-acetaldehyde mixture together with phosphoric acid into a 30 per cent aqueous primary-sodium phosphate at 90 DEG  C., the crotonaldehyde formed being run off.

Title: Means for preventing breakage due to resonance in high speed machinery
IPC: F16H55/14
Filed: 1922-10-05
Abstract: 210,486. Constantinesco, G. Oct. 5, 1922. Toothed wheels or the like in which vibrations occur are built up of metal laminae, amalgamated together, and arranged in such a way that the working stresses on the structure tend to produce slip between adjacent laminae so that the energy of vibration is degraded into heat by internal friction. As shown in Figs. 2 and 3, for a helical gear wheel, annular discs a of steel, bronze, or other metal are coated with tin, lead, solder or other alloy, or galvanized, assembled together, and heated and pressed so as to bind the whole mass together. The blank is cooled under pressure and shrunk on to a wheel b having side plates c secured by bolts d. Teeth 5 are cut in the circumference at an inclination to the axis. The laminated discs a may be in segments arranged in staggered formation. The laminae at the wheel sides mav be thicker than the remainder to prevent exfoliation. For spur wheels the plane of the laminae is inclined to the wheel axis. In a bevel wheel, the teeth may be cut on a blank consisting of an amalgamated tightlywound spiral. In a bevel wheel, as shown in Fig. 10, the ring on which the teeth are cut is built up of spiral segments 8 amalgamated together.

Patent GB-165431-A (GB)
Title: Improvements in or relating to pneumatic cushioning or shock absorbing devices for vehicles
IPC: F16F9/02
Filed: 1920-09-22
Abstract: 165,431. Holmes, B. B. June 19, 1920, [Convention date]. Pneumatic springs.-Consists of a pneumatic cushioning-device for vehicles in which is utilized a bellows which is subjected to external fluid pressure and of which the ends are guided. Fig. 1 shows a metallic bellows 10 secured at its upper end to a flange 9 on a steel cup 8 mounted on a bracket 6 attached to a rear axle 7. A steel tube 11 surrounds the bellows and has a head 12 threaded thereon and a flange 13 at the base over which the bellows is spun, and to lugs on which the shackle of a leaf spring 20 is attached, a rubber buffer 21 surrounding the upper bush. The cap 12 has a boss 22 threaded to carry a sleeve 23 between which and the cup 8 is preferably a lubricating bush 24, the fit not being air-tight. The sleeve 23 has screwed to its lower end a spider 25 carrying a disc valve 26 guided on a shouldered bleed tube 27 formed with a seat 29 for a valve 30 provided with a groove 31 and a depending stem 32 adapted to contact with a pad 33 on the bottom of the cup 8 to open the valve against its spring 34. Air is pumped into the device through a valved port 37, to a pressure sufficient to support the maximum load. Owing to the restricted passage between chambers A, B, running shocks tend to increase the pressure in chamber C until ordinary rises of pressure in the chamber B fail to open the valve 26. The riding position of the device is thus lowered until the stem 32 contacts to open the bleed valve, which remains open until the pressure in chamber B is raised sufficiently to allow the valve to close. To increase the dash-pot effect of the chamber B owing to the rise of pressure therein being greater than in the chamber A, unless relieved by flow to the chamber C, the spider 25 may have small air passages, and to vary the effect spiders with varying air passage may be used. If the device is not required to be self-regulative, as for the front axle, the parts 23, 26, 30 may be omitted and a tubular guide replace them. The Specification as open to inspection under Sect. 91 (3) (a) also describes an alternative construction utilizing a cylinder and piston, in which the casing 51, Fig. 3 (Cancelled), is threaded into a member 48 mounted on a spring horn 45 and clamps a buffer pad 52 thereon. A cap 53 closes the upper end of the casing and carries a tubular sleeve 55, which telescopes loosely with a tubular extension 60 of a piston 56 connected to the spring 46 by an offset link 59. An annular cup-holder 62 surrounds the eitension 60 and is clamped by a nut 63 and a spring- pressed rubber expander 64; or the cup-leather may be U-shaped and the nut omitted. The piston has a groove to receive a pad 69 from which an oil duct leads to the shackle bolt 57. The sleeve 55 carries a spider 25 and associated apparatus as in Fig. 1, and the space between the extension 60 and the casing 51 is filled with oil. The action of the device is similar to that of Fig. 1. This subject-matter does not appear in the Specification as accepted.

In a plunger-type electromagnet having a rotary output at shaft 53, the conversion from linear to rotary motion is made by an intermediate member 30 having wheels 43 riding on inclined tracks 46. Downward movement of armature 22 is transmitted through stem 21 and ball 37 to the member 30 which is returned, and perhaps biased downwardly, by a spring 69, and also carries the wheels 43 on spindles 42. The tracks 46 may be graded to compensate for the non-linearity of the electromagnet force (Fig. 3, not shown) or to operate in either direction (Fig. 4, not shown). The torque from member 30 is transmitted to the output shaft by means of pins 61 engaging radial slots in a disc 60 fixed to the output shaft. Thus the output shaft has no axial motion. One of the pins may extend into a motion-limiting slot 66 in the casing, or alternatively a ball may ride in short arcuate slots for the same purpose (Fig. 5, not shown). The positions of the wheels and cam-surfaces may be interchanged.

Title: Improvements relating to the storage and preservation of meat
IPC: A23B4/16
Filed: 1931-12-02
Abstract: Meat such as pork, mutton, ham, bacon, fowls, or game, but excluding beef, is preserved by a single stage process in a gaseous atmosphere at a suitable temperature by simultaneously withdrawing or displacing air from the meat storage chamber and replacing it by carbon dioxide alone or mixed with nitrogen so that the atmosphere in the chamber contains more carbon dioxide than oxygen, the chamber being at substantially atmospheric pressure.  The atmosphere used varies in composition according to the meat treated and at 30-34 DEG  F. about the following may be used, the rest of the atmosphere being in each case nitrogen.  For pork, 2 per cent oxygen, 85 per cent carbon dioxide; for mutton, 15 per cent oxygen, 25 per cent carbon dioxide; for bacon and smoked ham, 5 per cent oxygen, 75 per cent carbon dioxide; for fowls, 5 per cent oxygen, 80 per cent carbon dioxide. The storage chambers may be such as are used for storing and transporting beef under chilled conditions, but made gas-tight and provided with gas inlet passages and with outlet passages for the displaced air and vapours, pumps and fans being provided for accelerating the displacement of the air.  When enough gas has been introduced, the atmosphere in the chamber may be circulated by a fan or an air pump to ensure good mixing.  Means may be provided for circulating the atmosphere through an oxygen-absorbing medium, and for subjecting it to a liquefaction process to separate desired and undesired constituents.  Part of the atmosphere in the chamber may be replaced from time to time or continuously by fresh preserving gas or gas freshened by removal therefrom of part of its constituents, for example oxygen or emanations from the carcases. Part or all of the atmosphere may be replaced from time to time for a short period of time by pure nitrogen or fresh air to prevent adaptation of the bacteria to the new environment.  The carbon dioxide may be supplied from cylinders containing it in compressed or liquid form, or from generating apparatus, or by vaporizing solid carbon dioxide. Mixtures of carbon dioxide and nitrogen used may be products of combustion or produced by absorption of oxygen from air. Specifications 318,534, [Class 49, Food &c.], 391,256, and 393,935 are referred to.
