Title: Control and synchronsation of clocks
IPC: G04G99/00
Filed: 1973-04-03
Abstract: 1424857 Master and slave clock systems S W MISCHIATTI 3 April 1973 [12 April 1972] 15837/73 Heading G3T In a master and slave clock system a transmitter in a central station transmits to each slave clock coded signals, each signal conveying in coded form complete information as to the time to be displayed by the slave clocks, the display to each slave clock being up-dated on reception of each said signal - each slave clock includes means to compare the time displayed thereby with the received coded signal and means to up-date the time displayed if the compared information does not correspond. Any loss of synchronism is thus automatically corrected on receipt of the next coded signal since the display resulting from that signal is independent of the display prior to receipt of that signal. The signals may be transmitted by radio or cable. The transmitter T Fig. 2 receives input signals at 1 Hz by radio or cable or from a local stable frequency generator. An oscillator 2 generates a carrier frequency which is supplied via a line 3 to binary counters C 1  to C 6  which count seconds, minutes, hours, days of week, days in each month and months respectively. Units 4 and 5 take care of the variable days in the months and leap year respectively. In each signal from the transmitter the carrier wave is modulated by seven words each of 8-bits. The counters supply signals in ASCII code or binary-coded decimal. The data from the counters is prepared for transmission by a parallel-to-serial converter 6 or a scanner which derives six 8-bit words in series each second, each train of six words being preceded by a seventh word for synchronization purposes.  Each receiver R (one per slave clock) includes a serial-to-parallel converter 7' and an electronic sweep scanner 8 which directs each 8-bit word to a respective coder Si to S6 for seconds, minutes, hours, days &c. respectively. A comparator 9 compares the data from the coders with data representing the current display of the various display units. If the compared data correspond then the current display is left undisturbed. If there is not correspondance, a memory 10 is activated and operates a motor driving (e.g. driving flap type digital indicators) of the relevent display unit of the slave clock until corre-  spondance is achieved. Thus the display is updated each second.

Title: Improvements in or relating to the casting of easily oxidisable metals
IPC: B22D17/30
Filed: 1938-05-27
Abstract: 505,403. Casting-machines. WAGNER, K. F. May 27, 1938, No. 15844. Convention date, May 27, 1937. Addition to 475,541. [Class 83 (i)] Metal pouring.-In casting easily oxidizable metals, such as magnesium, as described in the parent Specification a charge of metal is received in an open-topped cylinder 9 which is submerged in the molten metal 2 in a crucible 1, freely supported by lugs 7, the cylinder and a plunger 13 are then raised by a head 23, Fig. 3, and rods 22 until the former seats in a passage 11. A plunger 10 is then raised in the cylinder by a rod 15 to transfer the molten metal to a transfer cylinder 14, which is then moved along a passage 12, Fig. 1, until it is in line with the plunger 19 for forcing the charge through a passage 18 into a mould, not shown. The residue is returned by a plunger 20 to the cylinder 14 which moves back to its original position where the residue is pushed through the passage 11 by the returning plunger 13 and strikes the conical end of the plunger 10 still in its upper position relative to the returning cylinder 9. The plunger 10 is then returned admitting a fresh charge of metal to the cylinder 9. A carrier 21 is clamped about the cylinder 9 and the ends of connecting rods 22 by bolts and cottars, as screws submerged in molten metal could not be unscrewed when required. The cover 25 rests on the crucible and carries one end of the member M in which the passages 11, 12 are formed, the whole being held by extensions 27, Fig. 3, of the member M and bolts 28 which are relatively cool. In order that the movement of the rods 22 may not be impeded by adhering metal they are carried freely through holes in the cover 25 and tubular caps 24 kept hot by gases escaping from the furnace. All the movements are effected by hydraulic pistons controlled in desired sequence, the cylinder 16, Fig. 1, for the transfer cylinder 14 being freely supported by a bracket 40, and connected to the member M by stays not shown, the furnace 3 is mounted on wheels to avoid irregularities caused by expansion due to heat. The transfer cylinder 14 may have edges 29, Fig. 4, to scrape adhering metal from the passage 12. Neutral gas may be admitted by a regulating valve 31, pipe 30, and groove 33 to the passage 12 and cylinder 14 and by a flexible pipe 36, bore 37, and non-return valve 35 to the passage 11.

Title: Improvements in or relating to weighing scales
IPC: G01G7/02
Filed: 1921-06-14
Abstract: 182,665. White, A. E., (Computing Scale Co.). June 14, 1921. Indicating-mechanism.-In a weighing scale the pull exerted by the load brings into operation a counter-pull device such as a solenoid', which operates through the intervention of a spring on the equivalent, and is deenergized when the load is balanced. The load produces a pull on a draw-rod 10 coupled to a contact beam 11. The beam works between electric contacts 12, 13, and is coupled to a spring 14. When the beam rises to the upper contact 13 an electric circuit is established through a solenoid 16 and through a releasing- magnet 20. The core 15 of the solenoid rises and extends the spring through the agency of gearing 23, 22, 24, whilst the releasing magnet 20 withdraws one or more spring-controlled pawls 19 from ratchet teeth 17 on the core. The increasing pull of the spring 14 breaks the circuit at the contact 13 and the pawl 19 holds the spring 14 in the extended position. If the beam touches the contact 12 a shunt circuit disengages the pawl 19 and the tension of the spring is relaxed until the beam rises and breaks the circuit. A rack 18 operates a pointer I to indicate the weight. A finer adjustment of the indicating-pointer is obtained by means of contacts 12<a>, 13<a> which control a solenoid 16<a>, releasing-magnet 20<a> and pawl 19<a> all operating in a similar manner on the members 16, 20, 19, the core 15<a> however actuating the indicating pointer through a lever 29 connected to the rack 24. When the contacts 12, 13 are in circuit, relays 33, 34, 35 break the circuits of the contacts 12a, 13a. At each weighing operation, during the course weighing effected by the core 15, the core 15a for the fine weighing is brought to its central position shown, by means of contacts 39, 40, 41, 42, 43 controlled bv a cam plate 37 attached to the core 15a. Other contacts 50, 51, 52, 53 limit the travel of the core in either direction and cause its return to the central position, at the same time initiating a movement of the core 15.
