Title: Improvements in and relating to apparatus for treating liquids or semi liquids
IPC: B01F5/06
Filed: 1931-03-17
Abstract: Homogenizing apparatus for treating mixtures of milk and butter, salad dressing, cream fillings for confectionery, and other materials, comprises a bowl or receptacle, partly shown at 10, Fig. 2, screwed on to a cylinder 3 in which moves a hollow ram 12 containing a constricted portion and a baffle.  Materials placed in the bowl 10 are drawn by the descent of the ram through one or more perforations in the end 7 of the cylinder 3 and are compressed and forced through the construction and past the baffle when the ram rises, the outlet from the bowl being closed by a ball valve 6, which may be spring-controlled.  The p  constriction may comprise a perforated plug in the ram, or, as shown in Figs. 2 and 4, may be formed by a plug 17 secured by screwing against a constriction 18 in the ram 12 and having a fine passage 19 opening into a larger passage 19a itself leading to the interior of the plug.  The lower end of the plug carries the baffle 20 and contains the outlet 17a for the treated materials. The upper end of the plug M is of V-shape and supports a ball 14 which does not obstruct the passage 19 but prevents leakage from the ram should the plug 17 require to be unscrewed, as by turning a milled head 21, while in use.  The cylinder 3 is secured in a bracket or a baseplate adapted to support the receptacle for the treated materials.  The ram 12 is reciprocated by a lever pivoted on the bracket and having a forked and slotted end engaging a cross pin in <PICT:0375317/III/1> <PICT:0375317/III/2> <PICT:0375317/III/3> the ram.  The baffle 20 may be formed by boring fine holes in the cross-pin.  In a modification, Fig. 9, passages 29 in the member 3 open, at their lower ends, into the side walls of the cylinder space 30, and, at the upper ends, beneath a mushroom baffle 31, preferably having spiral vanes 32 on its underside, arranged in the bowl 10; the materials drawn into the cylinder are at first returned to the bowl 10, thereby agitating its contents and maintaining the admixture thereof; when the rising ram closes the lower ends of the passages 29, homogenization takes place as above. The ball-valve 6 is in this case dispensed with.  The mushroom fitting may be provided in any of the constructions described and the action of the ball-valve 6 is then delayed by the provision of a spring or the like.  The Provisional Specification states that the apparatus may be mechanically driven.

Title: Improvements in and connected with anti-dazzle devices for use with head lamps
IPC: F21V5/04
Filed: 1932-03-18
Abstract: 395,455. Vehicle headlamps. ROSSI, P., Rossi's Garage, Ceylon Place, Eastbourne. March 18, 1932, No. 8133. [Classes 75 (ii) and 75 (iv).] Lantern screens; reflectors; adjusting reflectors from a distance.-The reflector of a vehicle headlamp having a screen of glass or other material, coloured or otherwise treated, which is moved from the exterior of the reflector to its interior so as to be located in front of the lamp, 'is formed so that part of it is movable relative to the remainder so as to provide an opening for the passage of the screen, the movement of the reflector part and of the screen being produced by momentarily operated electrical means. Four movements are involved, viz., opening the reflector segment, insertion of the screen, withdrawal of the screen, and closing the reflector segment. For each of these a pawl-locked solenoid armature is employed, the armatures operating in pairs. The means for opening the reflector segment is shown in the Figure. The rear part 2 of the reflector 1 is pivoted on a spindle 3, passing through two plates 9, 19 (the latter not shown) both mounted at the back of the reflector 1. An arm 6 fastened to one end of the spindle 3 is linked by means of a V-shaped pawl 13 and link 12 to the armature 11 of a solenoid 8. When the segment 2 is in the closed position shown, the pawl 13 engages over a lug 15 on a plate fixed to the plate 9, a spring 19a urging the arm 6 and pawl 13 together. Energizing the solenoid 8 retracts the armature 11, which disengages the pawl 13 and rotates the arm 6, so opening the reflector. A similar arrangement at the other end of the spindle 3 provides for closing the reflector when a second solenoid is energized, the pawl in this case holding the reflector part in the open position. Rotation of the spindle 38, on which the screen 5 is mounted by means of a pair of arms, is obtained by two devices operating in a similar manner. The four solenoids are controlled by a contact maker having four flexible arms with corresponding spring-loaded buttons, so that each solenoid can be energized successively. The spindle 38 is cranked at the centre where it carries a weight which normally rests against a cross-bar. The source of light is carried by the segment 2. Specification 370,119 is referred to. According to the Provisional Specification, the rear part of the reflector is carried by an arm which swings on a vertical axis, and is fixed to the pivoted end of a second arm having a bifurcated free end between the limbs of which is engaged a spring- loaded, pivoted pin lying across a core of a pair of coaxial solenoids. The core is provided with abutments so as to move the pin from one side to the other, and so move the rear part of the reflector. The pin may have a toggle or snap action. The coloured disc is carried by an arm fixed to a spindle carrying a pair of rocker arms connected to the cores of a pair of solenoids.
