Title: Improvements in or relating to a process for evaporating milk
IPC: A23C1/12
Filed: 1949-02-04
Abstract: Milk is evaporated under vacuum at a temperature of about 60 DEG F using a compressed refrigerant gas, e.g. amonmia, as heating-medium. The condensed refrigerant discharged from the heating-element of the evaporator, is cooled (by heat-exchange with water and/or by partial flash-corporation) and then used as cooling-liquid in the condenser for the steam evaporated from the milk, using the apparatus claimed in Specification 686,375 which relates to the evaporation of heat-sensitive aqueous solutions in general.  The evaporator itself preferably comprises three vertical tube heat-exchangers connected in series as claimed in Specification 682,170; the milk flows as a film down the interior surfaces of the tubes, and the unevaporated milk reaching the bottoms of the tubes is in part recirculated to the tops of the tubes.  The milk is pasteurized and de-aerated before it is supplied to the evaporator.  The milk is concentrated to about one-third of its original volume.  The concentrated milk withdrawn from the evaporator may be frozen and wrapped in paper containers, for storage.  Specification 686,377 also is referred to.ALSO:Milk is evaporated under vacuum at a temperature of about 60 DEG  F. using a compressed refrigerant gas, e.g. ammonia, as heating-medium.

Filed: 1963-01-25
Abstract: 1,027,645. Television. BLAUPUNKTWERKE G.m.b.H. Jan. 25, 1963 [Feb. 8, 1962], No. 3195/63. Heading H4F. [Also in Division H1D] In a television receiver in which the line structure of the reproduced image is eliminated by elongating the cross-section of the electron beam by means of magnets 33 while applying a negative D.C. potential to the focusing grid 30 (see Division H1) the drive of the video output stage 25 is increased by connecting the cathode of valve 25 to earth through a diode 42. The negative bias applied to the focusing grid is derived from a pulsed voltage present in the line time base stage 36. With the changeover switches 29, 32 in the position shown the magnets 33 are de-energized and the usual positive voltage is applied to the focusing grid by voltage divider 31. In another embodiment the capacitor 43 in the cathode circuit of video output stage 25 is connected to earth through the capacitor 28 in the focusing grid circuit whenever the switch 29 is in the position for applying a negative bias to the focusing grid. An A.C. potential dependent upon the deflection of the electron beam may also be applied to the focusing grid.

Title: Method and apparatus for moulding concrete
IPC: B28B1/087
Filed: 1934-01-31
Abstract: 427,213. Moulding concrete in shaking &c. machines. NAAMLOOZE VENNOOTSCHAP SCHOKBETON, 2A, Lindtsche dijk, Zwijndrecht, Holland. Jan. 31, 1934, No. 3287. Convention date, June 29, 1933. [Class 87 (ii)] Concrete articles such as piles, beams, pipes, or camp-shedding plates are moulded by subjecting a dry mix to a series of sudden impacts by causing a mould to fall repeatedly from a height of not more than 25 mm. and preventing the setting up of subsidiary vibrations by rigidly securing the mould to a rigid metal support 9 which impacts with an anvil 2 secured to or integral with a foundation 1. The impact is taken by isolated small areas such as ribs 10 on the support 9 so that the formation of an air cushion is prevented. The weight of the anvil is equal to or exceeds that of the support 9 and the weight of the foundation is at least six times that of the support. The weight of the falling parts is adapted to be not more than three times that of the anvil. The ribs 10 abut against ribs 4 on the anvil 2 in the lowest position. Cams 27 on rotating shafts 6 engage anti-friction rollers 12 mounted under the support 9 and so raise and let fall the support. Lugs 7 on the anvil carry vertical guide pins 8. Pairs of cams 27 rotate in opposite directions to assist in maintaining the parts in position. The cams may rotate at 150 revolutions per minute and allow the parts to fall freely through 8 mm. The number of shocks may be increased to 400 per minute. The mould consists of a bottom plate, side pieces and upper spacing members held together by bars 18, 19, 20 and wedges 22 and is secured to the support by yokes 26 engaging draw-bars 24 pivoted to the support. The mould may be provided with a tubular core which is withdrawn by a winch and the side pieces removed after the concrete has set. For setting the mould may be transported to a truly plane platform by a crane, ropes being passed through eyes 23 on the mould and through eyes on a longitudinal beam carried by the crane.

Filed: 1978-01-27
Abstract: The housing parts (6; 12, 13), which contain the end (9) of the supply lead and the terminal parts of the jacks (8) in subdivided accommodating chambers (7), are configured in the manner of half-shells (12, 13). The latter are mutually anchored by means of a hook-in connection (22, 24; 23, 25) which is active in the region of the entry fitting. A front part (1) of the connector containing the contact-making sections of the jacks (8) is configured as a single-part plug-on connecting piece which is provided with recesses (10) for accommodating the last-named jack sections and whose accommodating opening facing the housing parts (2; 12, 13) is tapered inwards and accommodates in a tightly-seated manner the assigned end of the half-shells (12, 13), which tapers outwards in a complementary fashion. Anchoring members both on the half-shells and on the inner cone of the front part (1) ensure that the parts cannot become detached accidentally. After the insertion of the supply lead and the contact pieces in the half-shells (12, 13), and the closure of the latter by producing the hook-in connection, the front part (1) of the connector is pushed onto the half-shells (12, 13), which are already connected to one another, in such a way that the front parts of the jacks are situated in the correct position in the recesses (10). Finally, the half-shells (12, 13) and the rear section of the front part (1) are further provided with a flexible sheath (2). <IMAGE>

Title: Electrical signal apparatus
IPC: H03K6/04
Filed: 1975-01-27
Abstract: 1486368 Measuring surface roughness electrically GOULD Inc 27 Jan 1975 [25 Jan 1974] 3498/75 Headings G1N and G1U The surface profile of a workpiece 10, Fig. 1 is sensed by a probe 11 which is supported by a reference bar 13 for movement across the surface of the workpiece, the resulting output signal being a curve A, Fig. 2, containing a bias, shown by the dotted line, due to the non-parallel relationship between the nominal surface of the workpiece 10 and the reference bar 13. To remove this bias the amplified signal V 1N , Fig. 5, from this probe 11 is fed through an integrator 16 acting as an LF filter for a period determined by timer 20 and arranged to coincide with a single sweep of the probe across the workpiece surface. Simultaneously a linear ramp generator 18 produces a voltage V X . At the end of a sweep the value of the output Vz from the integrator 16 is divided by the voltage Vx from the generator 18 to give a value V O  corresponding to the slope tan α of the bias. The ramp voltage V X  is multiplied at 22 by tan α to produce a voltage VM R identical with the component of voltage V 1N  due to the non-parallel relationship. This is subtracted at 23 from the signal voltage V 1N , leaving the surface roughness characteristics VR only. A unit marked TRAVERSE ensure that the ramp voltage V X  has an appropriate positive or negative slope consistent with the measured signal V 1N , and is reversed when the direction of scanning is reversed, and also energised an alarm if a reversal in the direction of scanning occurs during the test run. The apparatus initially produces a fast scanning speed to obtain the value of V O , and a slow scanning speed to obtain the profile characteristic
