Title: Dehydrated fermented milk products
Inventor: MEZCIEMS DAVIS JEKABS IVARS
IPC: A23C9/123
Filed: 1962-04-13
Abstract: A dehydrated milk product, particular yoghurt or kefir, comprises dehydrated curd, lactic acid and the typical flavouring materials present in the corresponding freshly fermented milk product, the proportions of lactic acid and of flavouring materials present in the dehydrated product being such that upon reconstitution of such product with a volume of milk substantially equal to the volume of aqueous liquid evaporated during dehydration, a product is produced having concentrations of lactic acid and the flavouring materials substantially equal to those of a similar freshly prepared conventional fermented milk product. In the production of a dehydrated yoghurt, the requisite concentration of flavouring materials for the dehydrated product may be achieved by: (i) inoculating milk with a starter strain comprising at least two known yoghurt-producing bacteria having different optimum fermentation temperatures and carrying out a part of the subsequent fermentation at substantially the optimum temperature for each bacterium, as exemplified by fermenting a mixed culture of Lactobacillus bulgaricus and Streptomyces thermophilus firstly at 37 DEG C and subsequently at 50 DEG C, (ii) using a greater proportion of inoculum and/or an enriched milk, exemplified by fermenting a mixed culture of L. bulgaricus and S. lactis at their optimum fermentation temperature of 37 DEG C, or (iii) including in the starter strain at least one bacterial strain e.g. of S. diacetylactis, S. cremoris and Betacoccus cremoris, which produces the typical flavouring substances of yoghurt but which is not conventionally used in its production, and carrying out a part of the subsequent fermentation at the optimum temperature for that bacterium.  Usually the fermentations are carried to a point at which at least twice the normal content of flavouring materials has been produced in the fermented milk product. The requisite content of lactic acid is ensured by introducing a culture of innocuous lactic acid-producing bacteria either into the fermenting milk or into the fermented product, or by adding lactic acid either prior to, or during the dehydration. The fermented product may be homogenized under a pressure of 500 lbs.per sq.in.and dehydrated by spray-drying.  Examples are disclosed.

Title: Improvements in automatic firearms
IPC: F41A5/32
Filed: 1918-09-17
Abstract: 138,136. Fairfax, H. W. Gabbett-. Sept. 17, 1918. Machine guns.-Relates to automatic guns of the kind described in Specification 128,354, in which the breech mechanism is operated by air or other fluid compressed by the energy developed on discharge, and consists in storing the air or fluid in one or more receivers, whence it may be taken as required for operating the gun. The invention is shown in Fig. 1 as applied to a barrel-recoil gun having a muzzle-sleeve B of the type described in Specification 128,515. This sleeve is driven forwardly against the action of a spring B' by the discharge gases as they escape from the muzzle, and through links D<2>, E, F causes a piston G to compress air in a cylinder H and deliver it to a receiver N through a pipe fitted with a non-return valve. A second piston G' working in a cylinder H<1> is connected by a link C<1> to a rod C rigidly fixed to the barrel A so that, when this recoils on discharge, compressed air is delivered to the receiver N through the pipe D<1>. The receiver N communicates with the action cylinder J<1> through a pipe P fitted with a valve P<1> adapted to be actuated by tappets R<1>, R<2>, on a rod R moving with the barrel A. Near the end of the recoil movement the tappet R<2> rotates the valve P<1> to connect the receiver N to the cylinder J<1>, whereupon the compressed air drives the piston J<2> rearwardly against the action of the return spring L to open the breech. On the return movement of the barrel, the tappet R<1> rotates the valve P<1> to disconnect the receiver N from the cylinder J<1> and to uncover an exhaust port P<3>, whereupon the spring L returns the actionpiston J<2> to close the breech. Another cylinder charged from the receiver N may be provided to actuate the cartridge-feed mechanism. The cylinders H, H<1> are provided with holes which, when uncovered by the pistons in their forward positions, serve to admit air at atmospheric pressure to the cylinders. A modification is described in which separate receivers are charged by the recoil cylinder and the gas cylinder; these receivers may be employed for performing separate functions. Either of the fluid compressing-devices may be employed separately. In one of the Provisional Specifications it is stated that normally the cylinders and receiver are filled with fluid under pressure.
