Title: Improvements in or relating to the manufacture of acetaldehyde
IPC: C07C45/38
Filed: 1931-09-11
Abstract: The water contained in the vapour mixture obtained by the oxidation and/or dehydrogenation of alcohol, is partly or wholly removed before condensation of the acetaldehyde by means of a solid, liquid or molten water-binding agent.  Suitable agents are calcium chloride, which may be more or less hydrated, barium and magnesium chlorides, and magnesium and copper sulphates; zinc chloride and sulphuric acid are not suitable.  The water-binding agent may be regenerated by heating, after removal from the absorption zone, or continuously with the reaction; they may be circulated continuously to a regeneration apparatus.  The dried acetaldehyde vapour may be condensed or absorbed in solvents such as glacial acetic acid which do not interfere with its subsequent use.  For the catalytic oxidation of the alcohol, the temperature may be 300-500 DEG  C., silver, copper, silver oxide and copper oxide being suitable catalysts.  Steam, nitrogen, or indifferent gas may be used to dilute the vapours, and the oxygen may be employed in the theoretical proportion or in less or more amount than this. In an example, the reaction vapours are cooled partially and passed through a bank of tubes at 120 DEG  C. charged with anhydrous calcium chloride, the tubes being arranged so that an exhausted bank of tubes may be cut out and regenerated by a current of air at 200 DEG  C.

Title: Improvements in and relating to self-supporting bags for golf-sticks and other stick-like articles
IPC: A63B55/04
Filed: 1928-09-05
Abstract: 322,748. Johnson, H. T. Sept. 5, 1928. Bags for golf clubs.-A support of the spiked rod type for a golf-bag forms or is provided with a divider of the mouth of the bag. A rod 1 ending in a spike 2 passes from a hand-grip 3 down the bag 4, the spike 2 being normally concealed in a sheath 5. The retraction of the spike 2 is effected by the action of a spring 11 housed within the sheath 5. This retraction is limited by a collar 12 fast on the rod 1 abutting against a stop 13, Fig. 6, screwed in the top of the sheath 5. The iod 1 is internally screw threaded at the top to receive a correspondingly screw threaded stem 14 of a T-piece 15 forming the hand-grip 3 through which passes a strap 16 threaded through slots 17 and 18 in the bag and buckled together at 21, thus dividing the mouth of the bag into two parts. The device can be accommodated to differently sized bags by providing extension pieces in the screw union at 14 and by adjustment of the flanged nut 8. In the case of a hooded bag an L-handle or a flexible handle is provided. With stiff bags the arrangement in Fig. 5 is adopted. In a modified form a flexible hand-grip may replace the rigid T- piece 15, being formed by riveting the strip to the spike rod 1. In a further modification, the sheath 5 may be threaded inside to take a screw ferrule 6, Fig. 8, to which a nut 26 is secured with a countersunk flange to retain a flat, domed, or spring washer 25. In the ferrule a closing plug may be screwed by a bayonet joint to retain the spike when the bag is carried.

Title: Device for four colour stereoscopic cinematography
IPC: G03B35/00
Filed: 1949-10-07
Abstract: 662,803. Optical systems. CRISTIANI, L. Oct. 7, 1949, No. 25847/49. Class 97 (i). Four images, forming two stereoscopic lefteye and right-eye colour component pairs, are produced by a system including means for producing first a pair of images, with a stereoscopic separation, which means divides the entry pupil of the system into two parts used by the two corresponding light beams which are then collimated and fall on pairs of faces of a pyramidal prism with which are associated pairs of complementary colour filters, the four light beams from the prism being used to form four adjacent images on a film. In the form shown, pairs of reflectors are disposed in front of an. objective 1 and comprise outer mirrors 3 and the faces of a prism 31. Separate mirrors or two rhomboidal prisms may be used instead. The objective produces stereoscopic images in superposition in the aperture 2<SP>1</SP> of a diaphragm 2. A field lens 4 and an objective 5 together have a principal focal plane at the diaphragm and, accordingly, parallel light falls on a pyramidal prism 6, with each face of which is associated a colour filter 7. Four images are formed in a normal film frame space at 9 by an objective 8. The four filters may be so chosen that their transmissions lie in four consecutive spectral zones so overlapping that the colours of the first and third, and second and fourth respectively form complementary pairs for use in the light beams from the two stereoscopic images. For projection the same optical system is used with polarizing filters for polarizing differently the light beams from the left- and right-eye colour component images. Polarizing spectacles are used for viewing wherein the polarizing material may occupy only a small area in front of the eye pupil.

Title: Improvements in and relating to locks
IPC: E05B55/00
Filed: 1944-12-28
Abstract: 622,195. Locks. WOLLASTON, H. J. BUCHANAN-. Dec. 28, 1944, No. 26042. [Class 44] In the lock described in Specification 510,179, a device for retaining the upper tumblers in unlocking position which is completely enclosed in the lock casing and which does not move relatively to them when engaged therewith is provided in the form of a rod, either integral or in parts which on withdrawal of the bolt is forced through holes in the upper tumblers. The movable rod 11, Fig. 1, is normally located in a hole in an extension 14 of the bolt body 1, with a head bearing on the rear wall of the lock casing. When the tumblers are lifted by the insertion of the key through the guide way 15, and the bolt body is retracted by the follower 7 operated by a handle, the rod 11 passes into aligned holes in the upper tumblers, holding them in the unlocking position. The bolt can then act as a simple latch bolt under control of the spring 8, the rod 11 remaining fully engaged with the tumblers. To permit re-locking, a lever 12 is operated by an outside knob to withdraw the rod by engagement with the head thereon ; movement of this lever is only possible with the bolt fully shot. In a modification, the rod is replaced by a series of small sections 23, Fig. 3 and 4, which in the locked position, Fig. 4, lie severally within the holes in the upper tumblers, with two end sections within holes in the bolt body, and which in unlocked position lie in off-set positions within the holes in the tumblers as shown in Fig. 3. At the front of the bolt body a thin rod 16, having a head at each end of the diameter of the holes in the tumblers and the bolt body, slides in a tube 17 fitting tightly in the hole in the bolt body, the permitted movement being equal to half the thickness of one tumbler. A similar rod 18 in a tube 19, with a head at the front end and a collar 21 near its rear end is provided at the rear of the bolt body. Between the collar 21 and a bracket 20 mounted on the bolt-body is a compression spring 22. When the bolt is shot from the unlocked position, "the pressure of the spring 22 on the sections 23 is relieved to allow the tumblers to fall by contact of the collar 21 with a fixed pin in the lock casing. In order to permit the bolt to act as a latch, its travel can be restricted by a screw 25, Fig. 3, when fully screwed into the casing, or by a leaf spring 24 which is strong enough to keep the bolt from being fully shot if the latter is allowed to come forward gently, but not if the door is slammed.
