Title: Electronic timepieces with alarms
IPC: G04G9/00
Filed: 1976-06-23
Abstract: 1518436 Electronic timepieces DAINI SEIKOSHA KK 23 June 1976 [24 June 1975] 26036/76 Heading G3T A digital electronic watch has an alarm sound producer 6, Fig. 1, and a plurality of alarm setting channels for pre-setting a plurality of alarm times and dates, a different sound (i.e. differing in tone or loudness) being produced for each channel selected. In Fig. 2, a 1 Hz signal from a frequency divider 13 steps seconds, minutes, hours and date counters 15-18 respectively. In normal operation switching circuits 22-24 feed the contents of the counters to a de-coder 25 to drive a time display 27. Alarm setting channels A, B and C comprise memory circuits 28, 29, 30 respectively, in the form of counters. Outputs of the memory circuits of the three channels are cyclically applied to coincidence circuits 19, 20, 21 by a time-sharing circuit 31, for comparison with the contents of the mins, hours and date counters 16, 17, 18. Coincidence of three of these units is detected by a coincidence circuit 39 the resulting output of which activates the alarm sound producing circuit 40. To pre-set the alarm times, a circuit 33 comprising a four stage ring counter, selects the channel in response to operation of a push-switch 32; one operation thereof selects channel A, two operations channel B and three operations channel C. A channel display control circuit 38 causes the numerals 1, 2, or 3 to appear in part 4 of the display, which is normally used for date, indicating channels A, B and C respectively. The outputs 33A, 33B, 33C of circuit 33 are fed to alarm-time-setting circuit 34, together with outputs of a memory selecting circuit 36 comprising a four-stage ring counter controlled by a switch 35 operated by stem 9, Fig. 1. Assuming that the hours memory in channel B is to be set, a 1 Hz signal from f divider 13 will be passed by the time setting circuit 34 from output 34 BH to hours memory 29 H, changing the contents thereof. A corresponding output 37 BH from a display control circuit 37 is applied to the switching circuit 23 causing the contents of memory 29 H to be fed to de-coder 25 and consequently displayed on portion 3 of display device 27. Figs. 7, 9, 11 (not shown) illustrate circuits for producing three different tones, derived by combining output signals of several stages of the f divider 13. Fig. 13 (not shown) illustrates a circuit for producing distinguishing sound signals in three degrees of loudness. One channel may be pre-set to cause an alarm to be produced at the same time each day and the other channels set to produce alarms at pre-set times on pre-set dates. To enable an alarm signal to be produced each day, a shown date coincidence signal is produced, the date memory counter being pre-set at a value higher than any date count.

Title: Method of controlling the feed of cigarette tobacco in cigarette making machines
IPC: A24C5/39
Filed: 1926-10-20
Abstract: 260,273. Grupe, W. F. Oct. 20, 1925, [Convention date]. No Patent granted (Sealing fee not paid). Cigarette-making machines. - Carded tobacco is fed to the pan of a scale or the like, which is set to tip at a predetermined weight, the contents of the pan being deposited upon an apron which is advanced at a uniform speed towards the hopper of the rod-forming mechanism. The hopper 19 is fitted with a carding roll 11, pin roll 12, feeding roll 15, agitating roll 17 and moving-belt 23, rotating in the directions indicated in Fig. 1, the belt 23 constituting the bottom of the hopper. The issuing stream is measured off by means of a beam scale having an adjustable weight 33 and pan 32 consisting of compartments 32<a>, 32b, 32<c>. Triangular portions of the studs 34 carrying the pan enter recesses in the beam 36. A member 38, having pawls equal in number to the compartments of the pan, is secured to one of the studs and is tripped by projections on a member 39. This is driven through toothed and bevel gearing from shaft 49 of the roll 50 over which moves the belt 46. When the pan is being tripped, the delivery from the stream 30 to the pan is discontinued by the withdrawal of the pin roll 12. For this purpose contacts 70, 78 are positioned on the beam 36 and support 79, and form part of an electric circuit containing a battery 72 and solenoid 75. Closing of the contacts due to the tipping of the pan therefore results in the withdrawal from engagement with the tobacco stream of the arm 81, which is secured to the armature of the solenoid and carries the pin roll 12 and paddle wheel 31. The successive charges of tobacco are deposited obliquely on the belt 46, and at the delivery end of the latter, portions of consecutive lots are jointly delivered to the hopper 62, the material being redistributed uniformly by rolls 65, 67. 3

Abstract: 902,227. Semi-conductor devices. WESTING- HOUSE ELECTRIC CORPORATION. Aug. 2, 1960 [Aug. 7, 1959], No. 26661/60. Class 37. A PN junction is formed by exposing a monocrystal of silicon carbide of one conductivity type at 1500-2000‹ C. to the vapour of an impurity of the opposite conductivity type, cooling the crystal and subsequently removing from part of its surface the region of the opposite conductivity type thus formed. In an example slices are cut from a crystal of P- type silicon carbide obtained as described in Specification 862,600 by growth from the vapour phase in an atmosphere containing argon and aluminium. One side of each slice is lapped with a diamond paste, washed in carbon tetrachloride and etched for 5 minutes in dilute hydrofluoric acid, after which the slices are loaded lapped face upwards in a graphite boat. After exposure for 6 hours in an induction furnace containing nitrogen at atmospheric pressure at 1800‹ C., the slices are cooled in the furnace. Phosphorus is an alternative to nitrogen as a donor impurity. The untapped sides are finally lapped to remove any N-type layer formed thereon, cleaned in carbon tetrachloride and etched in hydrofluoric acid and electrodes attached to the P-type material thus exposed and to the N layer on the lapped sides to form a PN diode.
