Title: Coupling components for use in colour photography and the manufacture thereof and of intermediates therefor
IPC: G03C7/32
Filed: 1940-01-03
Abstract: 537,921. Substituted benzene sulphonic acid chlorides and esters ; synthetic resins ; cellulose derivatives. KODAK, Ltd. (Eastman Kodak Co.). Jan. 3, 1940, Nos. 183 and 6941. [Classes 2 (ii) and 2 (iii)] [Also in Group XX] p-Benzoylacetaminobenzenesulphonyl chloride is prepared by the reaction of benzoylacetanilide with chlorsulphonic acid. p-(#-p<SP>1</SP>- Anisoylacetamino)-benzenesulphonyl chloride and p-acetaminobenzenesulphonyl chloride are similarly prepared.  Methyl, ethyl, n-propyl, n-amyl, ethylene- α : #<SP>1</SP>-di-, #-ethoxyethyl, #-benzyloxyethyl, #- (#-benzyloxyethoxy)-ethyl, #-(#-butoxyethoxy)- ethyl, and #-(p-ter-butylphenoxy)-ethyl pbenzoylacetaminobenzenesulphonates are prepared by the reaction of the appropriate alcohol with p-benzoylacetaminobenzenesulphonyl chloride in the presence of pyridine. The 2 :4-diamylphenyl ester is prepared by the reaction of the sodium salt of 2 : 4-diamylphenol with the sulphonyl chloride in xylene solution. #-(p-ter-Butylphenoxy)-ethyl- and - n - amyl p - - anisoylacetaminobenzenesulphonates are prepared by the first method, using p-anisoylacetaminobenzenesulphonyl chloride. The sulphonyl chlorides can also be condensed with alcohols in acetic acid solution using sodium acetate as the condensing agent. With higher water-insoluble alcohols, the condensation may be effected in the alcohol itself. The sulphonic chlorides may also be reacted with substances of high molecular weight containing hydroxyl groups, such as polybydroxystyrene, polyvinyl alcohol and cellulose or its derivatives. The specified benzoylacetamino derivatives may also be prepared by reacting p-acetaminobenzenesulphonylchloride with an alcohol, hydrolysing with aqueous hydrochloric acid to split off the acetyl group, and reacting the product with ethyl benzoylacetate. The sulphonic esters are useful as couplers in colour photography.

Title: Improvements in the lubrication systems of internal combustion engines
IPC: F01M1/16
Filed: 1923-01-03
Abstract: 208,916. Dennis Bros., Ltd., Dennis, J. C., and Charles, C. R. Jan. 3, 1923. Controlling flow of lubricant.-The supply of lubricant to an internal-combustion engine is automatically controlled by a valve connected to a piston, diaphragm or the like subjected to the suction in the induction systems. The valva chamber has at one end a passage D<2> communicating with the induction system through a pipe B<3>, and at the other end a lubricant inlet passage B<6> with a seating around it on which a loaded valve normally seats. A lateral outlet passage B<7> is arranged adjacent the valve. As shown in Fig. 1, a piston A<2> working in the valve chamber B is coned at one end to constitute the valve A which is normally pressed by a spring C, in an axial recess in the piston, against the seating B<4>. A flange B<5> is provided for securing the device to the underside of a supply tank E. The outlet passage B<7> leads to a sight-feed F with needle valve F<2>. The, pistons may be replaced by a diaphragm or bellows. In the form shown in Fig. 2, a diaphragm G also constitutes the valve, the diaphragm being normally pressed up by a spring J against the seating H<5>. The arrangement shown in Fig. 1 may be modified so as to give an increased supply as the suction diminishes, corresponding to an increased load, by providing a second seating at the other end of the passage B<6> for a second valve secured to the valve A by a stem extending with clearance through the passage B<6>.

Globe guards.-In a wire net for globes the lower ring is divided into semi-circular or other segments which are held together by a binding ring 4 or moved apart to permit withdrawal of the globe 1 between the segments. The segments each have a collar 2 provided at or about its lower edge with a bead 3 over which the binding ring is slipped, and they may also have outer collars 5 engageable by the hand for pressing the segments together. The wires 6 of the net merge into or are connected to helical springs 7 which terminate in eyes 8 penetrating apertures 9 in the outer collars and engaging a wire or wires 10 which are located in the channels between the collars 2 and 5 and have their ends turned over where they emerge from apertures in the outer collars.

Title: Improvements in and relating to transverse flow type blowers
IPC: F04D17/04
Filed: 1961-01-05
Abstract: 963,015. Transverse-flow blowers. T. HELMBOLD. Jan. 5, 1961 [April 8, 1960; June 3, 1960], No. 472/61. Heading F1C. In a transverse-flow blower with a guided standing vortex forming itself during operation, an essentially trough-shaped guiding body adapted in form to the vortex and serving to maintain it in position is arranged within the blower rotor in the region between the inlet and outlet channels. A cylindrical free vortex is formed in the flow through a transverse-flow blower by means of a trough-shaped stationary guide member 2, Fig. 2, located within the blower impeller 1, the outermost face of the guide member covering rather more than one pitch of the impeller blades. The guide member 2 may be of V or like angular shape. For the purpose of regulating the blower, the guide member 2 and an external guide member 10 may, as shown, be mounted on an arm 9 pivoted about the blower axis 3. The arm 9 also carries a cylinder 11 located at the centre of curvature of the member 2 and forming to some extent the core of the vortex. The cylinder 11 revolves with the vortex or may be positively driven in the direction of rotation of the vortex. The impeller shaft is surrounded by a freely rotatable hollow cylinder 12 which reduces the disruptive effect of the shaft on the flow. In a modification, the member 2 has two troughs, whereby two vortices are formed. The two troughs may be formed by a T-shaped member. Fig. 5 shows a multi-stage blower comprising three impellers 1 in series within a common housing 26. Each impeller is provided with two vortex-forming members 2, 15 carried by discs 19 at their ends and, if necessary, between their ends. In the three-stage blower shown in Fig. 6, the impellers 1 are arranged at equal distances from a rotatable cylinder 20 which can be constructed as or incorporate an electric motor which can also drive the impellers. If the cylinder 20 rotates in the same direction as the impellers, flow guides 21 extending over at least one impeller blade pitch may be interposed between it and each impeller. The inlet 22 is separated from the outlet by a partition 24 having an adjustable part 25 affording a variable by-pass.
