Title: Improvements in or relating to apparatus for making building blocks and the like
IPC: B28B3/02
Filed: 1964-05-21
Abstract: 1,066,221. Moulding building blocks. CHARLESFORD ENGINEERING CO. Ltd., and G. P. RANDS. Aug. 20, 1965 [May 21, 1964], No. 21068/64. Heading B5A. In a machine, which may be automatically operated, for moulding building blocks, a mixture of ash, cement and water is discharged from a hopper 10 to a wheeled box 23 which reciprocates between a position below the hopper to a position where it discharges the mixture, by gravity, to a mould box 45 which is open at both ends and is partitioned to provide four building blocks simultaneously when the mixture is compressed by a tamping head 14. The mould box rests on a pallet and, during tamping, is oscillated pneumatically by a device 77. After tamping, the mould box is raised away from the moulded blocks, the upper ends of the blocks being held down by the tamping head, and the block-carrying pallet is fed on to a conveyer. The box 23, which has an open bottom, runs on rails and slides over a plate 41, providing a moulding mixture support plate which terminates adjacent the top of the mould box; it is connected at 27, 28 to a hopper closure 18 so that the hopper is automatically opened or closed depending on the position of the filler box. The latter is reciprocated by an hydraulic motor 31 via parallel rods (37), Fig. 5 (not shown), which pass slidably through the box and have end stops (38), thereby providing lost motion between the motor and the box. The powdered mixture therein is compacted by a grid (39), supported by the rods and reciprocated by the motor 31. The drives to the mould box, tamping head and pallets are effected by hydraulic motors 51, 74 and (63). Each compartment in the mould box is tamped by a plate 70 at the lower ends of a bank of three rams 69 attached at their upper ends to an assembly 71, 72, 73 slidably mounted on vertical guide rods 49.

Title: Hypochlorite compositions
IPC: C01B11/06
Filed: 1929-07-12
Abstract: 317,437. Mathieson Alkali Works, (Assignees of MacMullin, R.B., and Taylor, M. C.). Aug. 16, 1928, [Convention date]. Bleaching, materials for.-A triple salt of calcium hydrochlorite, sodium hypochlorite, and sodium chloride corresponding to the formula Ca(OCl)2.NaOCl.NaCl.12H2O, which is comparatively stable below 22‹ C. and may be used for bleaching, is obtained by bringing together in the presence of water calcium, sodium, chlorine, and hypochlorite ions in sufficient concentration and at a sufficiently low temperature to give the salt in crystalline form. For example, sodium chloride may be added to a saturated solution of calcium hypochlorite at a temperature of 16‹ C. or lower and the solution be seeded with crystals of the triple salt, or a mixture of caustic soda, calcium hydroxide, and water in the proportions say of 40 : 37 : 180 may be chlorinated below 16‹ C., say at 10‹ C. From the triple salt a. stable mixture of calcium hypochlorite with sodium chlorite may be obtained by the action of calcium chloride, for instance in quantity equivalent to the sodium hypochlorite content of the former, in a limited amount of water at a low temperature; whilst a product richer in calcium hypochlorite may be obtained by using for this treatment a chlorinated lime slurry containing calcium hypochlorite crystals and calcium chloride in solution. For instance, the chlorinated slurry may be mixed with the triple salt at say 10‹ C. and the mixture be then heated above the transformation temperature of the latter.

Patent GB-1198222-A (GB)
Title: Phase Comparator
Inventor: STEVENS MICHAEL CHARLES
IPC: H03K5/26
Filed: 1968-05-08
Abstract: 1,198,222. Frequency and phase comparators; automatic phase control. A. C. COSSOR Ltd. 3 April, 1969 [8 May, 1968], No. 21766/68. Heading H3A. A phase comparator of the type comprising a bi-stable circuit which is set and reset by the two input signal includes a frequency comparator which inhibits the bi-stable when the two frequencies are different and provides an alternative output. Input signal f 0  is applied to terminal 32, Fig. 2, in the form of a squarewave, and the other input signal f is applied to terminal 34 in the form of short pulses. With the two frequencies the same, and f leading f 0  hi-stable 42 is set by the short pulses and is reset by the trailing edges of the squarewave pulses to produce an output on line 22. The short pulses are lengthened by monostable 54, the squarewave pulses are shortened by gates 38-41 and the two sets of desired output are fed to bi-stable 44 which produces a similar output on line 24 when f lags f 0 . If the frequencies differ, the frequency comparator provides a signal on line 78 which inhibits both bi-stables 42, 44 and also provides alternative output signals on lines 74, 66 depending on whether / is greater or less than f 0 . The signals on lines 32, 58, 60 of Fig. 2 are fed to the corresponding line of the frequency comparator, Fig. 3. If f is greater that f 0 , the signal the CL input of divider 62 continuously resets it before divider 64 can be triggered, and no output appears on line 66. Dividers 68, 70 are however both triggered to produce an output on line 74, which is fed to gate 48 in Fig. 2 to provide an alternative output on line 22. Similarly if f is less than f 0  and dividers 62, 64 are both triggered and divider 70 is not. In this condition the output from bi-stable 64 on line 66 is fed via gate 56 of Fig. 2 to line 24. Outputs on either of lines 66, 74 result in a monostable 76 being switched to provide the signal on line 78 which inhibits the bi-stables 42, 44 so that gates 48, 56 receive only the signals from the frequency comparator. The comparator is used in an automatic frequency control system, Fig. 1, in which the output from an oscillator 10 is fed to a variable frequency divider 16, and the resulting output f compared with a reference frequency f 0  from a standard source 18. The "load" and "lag" outputs from the comparator 20, 28 on lines 22, 24 are fed to a varactor diode circuit 26 which adjusts the frequency of oscillator 10.

After homogenizing the billet by annealing, it is first extruded at 700-850 F. to produce a reduction in area of 20-75%. During the second extrusion, the billet is extruded at an extrusion ratio of not more than 30 : 1, the extrusion speed and the billet container temperature being controlled to prevent an undue rise in temperature of the billet. The extrudate is quenched by moving it through a water quench. Alternatively, the extrudate may be transported through an insulating tunnel to maintain its temperature and is quenched after it has been separated from the die. The extrudate is finally straightened and aged.

Abstract: 637,820. Cathode-ray tubes. WESTERN ELECTRIC CO., Inc. Aug. 8, 1947, No. 22025. Convention date, March 22, 1946. [Class 39 (i)] [Also in Groups XXXIX and XL (c)] A varying voltage representative of a telephonic or other signal is sampled at recurrent intervals and the sample voltages used to deflect a cathode-ray beam along one co-ordinate. Between consecutive samples, the beam is deflected along the other co-ordinate to traverse a coding element producing a group of pulses representing the voltage of the preceding sample. The coding element may be arranged to produce groups of pulses in accordance with the binary scale. The sample voltages are fed through a. cathode follower 56 and amplifier 58 to the vertical deflecting plates of the C.R. tube 60. Between the taking of consecutive voltages, the C.R. beam is given a horizontal sweep by a saw-tooth voltage generated across the condenser 12 of the relaxation and fed to the C.R. tube through a cathode follower 30. The fluorescent screen of the tube is covered on the outside or inside by a mask, perforated in the manner shown in Fig. 2 to represent consecutive numbers in the binary scale. As the beam passes a perforation, light passes through lens 65 to a photo-electric cell 66, and gives rise to a pulse which is amplified at 69 and transmitted by the radio or like transmitter 71. Instead of a fluorescent screen the C.R. tube may have a metallic target electrode located behind a perforated mask, and the output may be taken across a resistor connected between the target and earth, or between the mask and earth (Fig. 5, not shown). Specifications 630,094 and 637,848, [both in Group XL (c)], are referred to.
