Title: Method for the determination of instantaneous velocities in liquids
IPC: H01G11/02
Filed: 1964-10-01
Abstract: 1, 066, 867. Measuring liquid flow electrically. CESKOSLOVENKA AKADEMIE VED. Oct. 1, 1964 [Oct. 19, 1963], No. 39922/64. Heading G1N. In order to determine the velocity of flow of a liquid V, particularly for examining turbulence, a redox compound is dissolved in the liquid, two electrodes M, P are placed in the liquid and connected to a battery E, the current through the liquid being determined by the concentration of redox particles at the measuring electrode M, and its magnitude as shown on a meter I is therefore indicative of the velocity of the liquid. The measuring probe M comprises a thin platinum wire, and the supplementary probe P comprises a thin platinum plate, which is placed in line with the direction of fluid flow to avoid disturbing the flow pattern. Several measuring probes M may be used at different locations with a common supplementary probe P.

Abstract: 1521753 Cleaning vehicle windscreens WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 30 Sept 1975 [4 Oct 1974] 39993/75 Heading A4F [Also in Division H2]  In a vehicle windscreen wiping and washing unit having an electric wiper motor M2 temporarily energized when an electric washer motor M1 is energized by means of switch S1, a relay Rel 1 and associated contact K2 are arranged in circuit with the motors, and a PTC resistor is arranged in series with the contact K2 to delay de-energization of the wiper motor M2 when switch S is opened. As shown operation of switch S1 energizes washer motor M1 and relay Rel 1 which closes contacts K1 and K2 to energize wiper motor M2 and to apply voltage across the PTC resistor. After switch S1 is switched off the voltage across relay Rel 1, and thus energization of wiper motor M2, is maintained until the PTC resistor self-heats and its resistance increases sufficiently to switch the relay Rel 1 and open contacts K1, K2. In a modification Fig. 2 (not shown) a series connected circuit comprising a relay (Rel. 2), the PTC resistor, and a relay switch (K3) is connected in parallel with the washer motor Ml and a series-connected switch S1. The wiper motor M2 can be energized for continuous operation by switch S2 and a limit switch S3 may be provided to brake the wipers as they approach their parked positions.

Title: Process for preparing yogourt in powdered form
IPC: A23C9/123
Filed: 1957-12-24
Abstract: Yogourt in powder form is obtained by pasteurizing or flash superheating skimmed milk, inoculating with fresh cultures of Bacillus acidophilus and Bacillus bulgaricus, incubating adjusting to pH 3.5 by means of a food acid, e.g. lactic acid, adding a proteolytic enzyme such as pepsin, allowing to ferment, neutrallizing and desiccating.  In the example, skimmed milk is pasteurized or sterilized, cooled and divided into three.  One portion is inoculated with Bacillus bulgaricus, one with Bacillus acidophilus and the other is concentrated to 50% of its volume and is then admixed with the previously inoculated milk cultures. After incubation until the pH is 4.0, the pH is adjusted to 3.5 with hydrochloric acid or other acid acceptable for human consumption such as lactic acid and is then treated with pepsin. After degradation of the proteins in the milk, the product is neutralized, homogerized and dried.  Alternatively, the milk may be acidified to pH 3.5, treated with the proteolytic enzyme, neutralized, pasteurized, inoculated with the above cultures, incubated and then desiccated.

Abstract: 1,182,847. Axial-flow fans. PAPSTMOTOREN K. G. Aug. 22, 1968 [Aug. 23, 1967], No.40249/68. Heading F1C. A fan driven by an electric motor comprises a frame with an aperture of circular cross-section for the passage of air and at least one spoke supporting the motor, a guide wall of the frame surrounding the air stream, and an impeller within the aperture and having blades projecting upstream of the guide wall axially beyond the guide wall and outside the guide wall in a radial direction freely beyond the diameter of the aperture. The fan shown in Fig. 2 comprises impeller blades 11 carried by the external rotor 10 of the electric driving motor, the motor stator 8 being supported by spokes 6. A frame 3 of square external shape has a circular opening forming a guide wall 3a surrounding the impeller. As shown, the impeller blades 11 extend beyond the frame 3 in an upstream direction, with a maximum diameter 7% greater than the diameter of the circular opening of the frame 3. As shown by arrows, air enters the impeller not only along the front edges of the blades 11 but also along the outer edges 12, whereby 30% more air is drawn into the fan. The impeller blades 11 also extend beyond the frame 3 in a downstream direction and this extension may also have a maximum diameter greater the diameter of the opening in the frame 3. In this case, to enable the impeller to be inserted through the opening, the impeller blades may be made of resilient synthetic material so that they can be deformed during the insertion. Alternatively, the frame 3 may be made in two parts, or the downstream part of the impeller may be a separate member carrying separate blades (19, Fig. 8, not shown), or extensions 20, Fig. 9, may be fastened to the blades 11 either at the downstream end as shown or at the upstream end. The extensions may also be used for balancing the impeller. The guide wall 3a may be continued by a funnel-shaped ring 3b, with rings 3c to subdivide the flow. The leading edge of each blade 11 may be inclined backwardly or forwardly in relation to a radial plane through the impeller axis. The motor may be reversed in position, with the supporting spokes 6 at the inlet end of the fan.

A toy comprises a stationary frame 12 carried on straps 14 for suspension from the sides of a cot and includes an animatible activity member, e.g. a miniature roundabout, 18, mounted for movement in the frame and connected via an operating mechanism to an handle 48 adapted to be gripped by both hands of an infant whereby the member is animated by pulling on the handle. The operating mechanism incorporates a device effective to store energy during pulling of the handle and to release such energy on release of the handle to restore the handle and member to their original positions. This device may be a spiral coil spring connected to a bobbin on the base of the e.g. roundabout, a cord from each end of the handle being wrapped round the bobbin for operation thereof (Fig. 4, not shown). Alternatively the handle may terminate inside the roundabout in a helically twisted strip which engages a slot in the base of the roundabout and wherein a helical compression spring acts to return the handle (Fig. 5, not shown). The frame may take the oval form shown and be provided with small bells 80 which are struck by the figurines 78 of the roundabout as they swing outwards when the roundabout rotates. Additional handles 84 may be rotatably mounted on the frame for an infant to pull himself up with.

Abstract: 1354341 Moulding foam sheets UNIFOAM AG 1 Sept 1971 [1 Sept 1970] 40838/71 Heading B5A [Also in Divisions B1-B2] In a method of producing a continuous polyurethane foam sheet, the liquid foamable reactants are fed into the bottom of a trough 12 in which they foam and expand and, before foaming is complete, flow over the top of a weir structure 30 on to a moving sheet 19 supported by a plate 16 and conveyer 13; two moving vertical side sheets 22 supported by side walls 24 define with the bottom sheet 19 an open topped channel shaped conveyer in which the partially formed foam is moved away from the weir structure and allowed to completely foam and cure. As shown in Fig. 2, the trough 12 is divided by baffles 29 into compartments, each of which is fed by a pipe 11a to ensure that reactants of the same "age" are received in all parts of the trough. Various modifications are described in which the shape and inclination of the plate 16 may be altered to accommodate different foamable mixtures having differing rates of foaming &c. (Figs. 3, 3a, not shown) and also in which the shape of the weir structure may be varied to ensure an even foam distribution across the conveyer (Figs. 5a, 5b, 5c, 6a, 6b, not shown). The conveyer may be completely horizontal, as in Fig. 7 (not shown).
