[Also in Division G1] Apparatus for hatching and weighing pourable materials in conjunction with a transport hoist comprises a loading skip and a carrier for supporting the skip during its vertical motion on the hoist, the skip being arranged to be separated from the carrier in the lowermost position of the skip, the carrier having two projecting arms for supporting the skip and the apparatus incorporating a weighing support having two arms which register with the arms on the carrier in its lowermost position so that the skip can be transferred along the arms on to the weighing support and returned to the carrier after loading and weighing. In the form shown, the skip 4 is carried by arms 6 on a slide 5 running on rollers 8 on rails 7. The slide 5 and skip 4 are lowered by a cable 9 until the arms 6 are aligned with the arms 12 of a weighbeam, one end of which is mounted on a block 14 and the other end connected by a linkage 15 to the weighing machine. Further slackening of the cable 9 causes the skip to travel on to the arms 12 in which position material arranged segmentally around a batching device 2 is fed into the skip through an outlet 1. On completion of the weighing operation, the skip is withdrawn on to the arms 6 by means of the cable 9 and the skip and slide are raised to the desired level e.g. of a concrete mixer. The skip has rollers 10, 11 running on the upper side and rollers 16 on the underside of the arms 6, 12. The slide 5 is locked in its lowered position by a pivoted arm 17 having a nose engaging a recess in the rail 7 under spring action, the arm being moved out of operative position by contact with the rear wall of the skip.

Abstract: 1522630 Semiconductor-device manufacture MATSUSHITA ELECTRONICS CORP 15 Oct 1975 [18 act 1974 20 Nov 1974] 42110/75 Heading H1K During manufacture of a semiconductor device one or more recesses are formed in one face of a semiconductor wafer, a layer of etchable material is applied so as to be thicker in the recesses than on the intervening regions, the material removed progressively by etching treatment, e.g. in a low pressure oxygen glow discharge until the said intervening regions are exposed, and the material remaining in the recesses used as a mask in treatment of the exposed surface to form a layer of different conductivity thereon. To make a JUGFET the surface of an epitaxial layer on a more highly doped P type Si substrate constituting the drain is recessed by etching through thermal oxide masking to leave a mesa of serpentine form, the masking being retained for formation of the gate region in the recessed area by ion implantation and then removed. After formation of a thermal oxide layer overall the acid-resisting layer, e.g. of a rubber derivative or other specified material is applied overall and partially removed to expose the mesa, the oxide thereon removed by etching and dopant diffused in to form a source region. Source, drain and gate contacts are then formed. To make a photodiode target array a lightly doped N-type Si wafer is divided into targets of the required area, the backsides of which are then etched to form a diaphragm supported by a thick rim and then diffused with phosphorus and heat treated in hydrogen. Intersecting grooves are then formed in the front face of the wafer, to define a rectangular array of mesas, the face coated with thermal oxide, the acid resist applied and confined to the grooves as described above, the exposed oxide removed and boron diffused in to form PN junctions in the mesas.

Title: Refining process comprising deacidification and deodorization of glyceride oils and fats and equipment for said process
IPC: C11B3/14
Filed: 1964-10-15
Abstract: <PICT:1080057/C4-C5/1> A refining, i.e. deodorization and deacidification process for glyceride oils and fats in which the hot product to be refined is steam-stripped under vacuum is characterized in that the steam is introduced at a pressure which is about the same value as the vacuum under which the process is carried out and at a temperature lower than that of the hot product to be refined, and in that after the stripping operation the steam is precipitated in a refrigeration step which precedes the step in which the vacuum source is operating.  An oil rotary pump is the preferred sole vacuum source, producing a vacuum of 0.1-0.8 mm. Hg.; steam for stripping is obtained by evaporation of water at room temperature under this vacuum and is introduced at 10-35 DEG  C. into the hot product at 170-230 DEG  C.  The process may be operated intermittently or continuously as in Figs. 1; (2) respectively, in which still 4;(41) is supplied with "cold" steam from evaporator 5; (51,511) under vacuum from oil rotary pump 12.

In a circuit for producing an output voltage having a frequency variable in dependence on a control signal, and of the type in which a highfrequency A.C. input signal is sampled at a slightly different frequency, the sampling signal is produced by deriving a sawtooth signal having a slope proportional to the control signal amplitude, and comparing it with a fixed sawtooth signal derived from the input signal. The output signal is used to control a servomotor 10. Converter circuit, Fig. 2.-The input signal from generator 11 is fed to unit 12 which modulates its amplitude in accordance with the control signal S in  to compensate for the decreased reactance of the windings of motor 10 at low frequencies. The output from 12 is fed to phaseshifter 13 to produce a three-phase output which is then sampled by electronic switches S 1 , S 2 , S 3  (controlled by sampling circuit 15) to produce an output having a frequency which is the difference between the input frequency and the sampling frequency. This signal is then filtered by LP 1 , LP 2 , LP 3  to produce a sinusoidal signal, which after amplification at A 1 , A 2 , A 3  is fed to the motor 10. Sampling circuit. Fig. 5.-The control signal S in  is applied directly and via an inverter 24 to the two fixed contacts of a changeover switch 23, the movable contact of which is connected to the input of integrator 25. Whenever the integrator output reaches predetermined limits, unit 26 changes its state, producing a squarewave C, Fig. 6, which actuates switch 23, to produce at B a sawtooth, B, having a slope controlled by the signal S in - The input signal from generator 11 is converted to a constant sawtooth A in unit 20, and the two waveforms A, B are fed to a comparator 21 to produce waveform D, E. After shaping in 27, the resulting signals G, H are fed together with signal C to logic circuit 28 which produces the output I = G.C + H.C to actuate the switching elements S 1 , S 2 , S 3  in the main converter.

[Also in Divisions A4 and F2] A locking device for locking a vehicle safety belt includes a reel biased by a spring for retracting the belt, a locking member engageable with a member, coaxial and rotatable with the reel to lock the reel against rotation and an inertia body which moves in any horizontal direction to displace the locking member to lock the reel as the result of an acceleration of the vehicle above a predetermined value. A shoulder belt passes over the back of a vehicle seat and extends by a cable 10 to. a housing for the device beneath the seat. The cable is wound on a drum 32 rotatable on a spindle 31 and retractable by a spring 19. An inertia ring 28 is freely suspended by chains 30 within the housing and supports, by leaf springs, pawls 35, which pivot to engage a ratchet wheel 33 on the spindle at a predetermined acceleration of the device and so lock the reel against further rotation. The movement of the ring is restrained by springs connected to the housing. Alternatively, the positions of the ratchet wheel and inertia member are reversed, the inertia member lying within the ratchet wheel and the pawls are oppositely directed. The drum may be mounted on a screw so that as the belt is withdrawn the drum descends on the screw until stops 41, 42 on the drum and ratchet wheel engage, on further withdrawal the drum and ratchet wheel rotate together against the action of the spring 19 and a strong spring 40 between the ratchet wheel and casing. The inertia member may be integral with the pawl and be freely suspended or supported on a helical spring. The ratchet teeth are then concave in shape. A second ratchet wheel may be incorporated geared to the drum shaft and situated on the opposite side of the inertia member to the first ratchet wheel. The inertia member has oppositely directed pawls to engage with the ratchet wheels.
