Patent GB-982618-A (GB)
Title: An improvement in or relating to a unit for filtering dust-laden air
Inventor: BAXENDALE RICHARD HENRY
IPC: B01D46/04
Filed: 1963-02-02
Abstract: In a dust collector unit the contaminated air is passed through filter bags inwards through the filter walls and the dust collected in a tray beneath the filters.  Dislodgment of dust from the filter outer surface is effected by a flexible mattress within each filter bag which may be vibrated by a mechanism coupled to a handle external to the unit case.  The vibrating mechanism extends into the bags through the open end and is in the clean air side.  The bag open end is vertical and the contaminated air passes downwards over and between the bags and then through the walls so as to emerge, cleaned, through the vertical outlets.  The collecting tray is undisturbed by air flow.  Specifications 905,113 and 982,617 are referred to.

Filed: 1955-02-15
Abstract: 770,363. Riveting. WING, G. S., KIRK, A. J., WING, G. D., WING, Z. S., CESSNA, G., CESSNA, M. E., KIRK, E. A., KIRK, A. P., and REED, C. C., [trading as HI-SHEAR RIVET TOOL CO.]. Feb. 15, 1955 [Feb. 23, 1954], No. 4527/55. Class 83 (4). [Also in Group XXV] A method of setting a tubular rivet having a unitary head and shank with an axial hole therethrough, is characterized in that an expander nut having a diameter larger than the hole is pulled into said hole from the shank end, said pull being exerted from the head side of the rivet by a mandrel, having a diameter smaller than the axial hole, which is attached to the nut and passed through the hole to said head side, the nut expanding said shank to surround and retain the nut and finally detaching the mandrel from the nut and withdrawing the mandrel from the hole. A blind tubular rivet having a countersunk or flat head is placed on a screw-threaded mandrel 29, an expander nut 22 is screwed on to the mandrel and the assembly inserted through the plates 20 and 21 to be riveted together. The expander nut has a chamfered entry 37 to its threaded bore, and is provided externally with a deflector portion 38, an expander portion 41 and a retainer portion 44 which locks and retains a core screw 53 (Fig. 1) with its spring-like members 35. In operation, a setting device (not shown) is attached to the rivet assembly and the nut is pulled into the rivet shank. Knurling 42 on the expander portion of the nut prevents the nut from turning relative to the rivet. The deflector portion of the nut tends to curl the shank so that it shrinks back to contact the expander portion 41 and also clenches the nut and locks it firmly in the upset head.

Filed: 1926-02-27
Abstract: 248,391. Potts, H. E., (Gruyere Usines LaitiÞres Soc. Anon.). Feb. 27, 1926. Preserving milk.-For use in making milk or cream chocolate a preparation of sugar and cream, milk, or milk enriched in fat content, is evaporated in vacuum apparatus until a milky mass practically free from water is obtained, this mass being then moulded into bars or blocks while still warm. The milk may be pasteurized before the dehydration; and, instead of mixing cream or butter fat with the whole milk it may be added to milk which has been evaporated. The bars or blocks may be preserved by coating them with a protective substance such as cocoanut oil or cocoa butter, for example, by dipping the bars into melted cocoa butter. Or, as preservative may be used (1) a liquid produced from roasted peeled cocoa beans after treatment by heated rollers, and mixed, if desired, with cocoa butter or sugar or both (2) mixtures of sugar and starch syrup, or (3) alcohol, in which small quantities of flavouring matters such as vanillin may be dissolved. Cocoa butter may also be mixed with the milk or cream prior to, or during, the dehydrating process. In making the milk or cream cholocate the block mill in the form of lumps is mixed with cocoa, sugar and cocoa butter to form a doughy mass which is passed between rollers and then ground for about 3 hours while further cocoa butter is added; the temperature is then raised gradually to 85‹ C. and the grinding continued for 4 hours more, when the material is cooled and the working of the mill maintained for another hour.

Title: Improvements in or relating to centrifugal separators
Inventor: MANSA JOHAN LUDVIG
IPC: B04B1/18
Filed: 1962-02-14
Abstract: 926,406. Centrifugal separators. KOEFOED, HAUBERG, MARSTRAND OG HELWEG AKTIESELSKABET TITAN. Feb. 14, 1962, No. 5738/62. Class 23. The lower part 4 of a rotary centrifugal bowl is surrounded by an annular piston 1, Fig. 1, which is reciprocated to periodically open and close a peripheral sludge discharge outlet 2 between the part 4 and an upper part 3 with the aid of control liquid introduced under centrifugal force into two annular chambers 9, 10 defined by the piston and the shell, the chamber 9 being bounded on its upper side by a surface of the piston and receiving control liquid to cause the piston to rise via channels 13 communicating with a space 12 in which the liquid is squirted by a stationary pipe 11 and the chamber 10 being bounded on its lower side by a surface of the piston so that the pressure of control liquid in that chamber causes the piston to sink. To open the outlet 2, the supply of liquid is increased above that fed to chamber 9 so that a part of the liquid passes into a space 14 and enters the chamber 10 through channels 15. The area of the piston radial surface exposed to liquid pressure being greater in the chamber 10 than in the chamber 9, the piston is caused to move downwards. In Fig. 2, the chamber 10 is fed separately with control liquid through a pipe 11a, the channel 15 being closed by a plug 15a. A valve V regulates the liquid content of the chamber 9. Part of the liquid supplied through the pipe 11 passes through channels V1 into the valve V where the hydraulic pressure prevailing causes a hollow body V2 to close the discharge channel V5 so that the liquid pressure in the chamber 9 builds up sufficiently to cause the piston 1 to close the outlet 2. To open the outlet, supply of liquid to the chamber 10 is effected without that to the chamber 9 being interrupted so that a slow opening movement of the piston occurs. Alternatively, the supply through the pipe 11 is interrupted and the piston moves rapidly to open the outlet 2 completely. The valve V and the parts V1, V2 and V5 may be dispensed with and the chamber 9 be provided with a narrow discharge channel V4 to control the liquid content of the chamber.
