Patent GB-797912-A (GB)
Title: Digital information storage devices
Inventor: DAVIES DONALD WATTS
IPC: G11C21/00
Filed: 1956-03-21
Abstract: 797,912. Electric digital-data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 21, 1957 [March 21, 1956], No. 8826/56. Class 106 (1). A digital information storage device includes a main store with a capacity of one major cycle and a subsidiary store with a capacity of one word, each store having a normally operative separate circulation path and the two stores having a common circulation path which is not normally operative, switching means for rendering the separate circulation paths inoperative and for rendering the common circulation path operative and an input path, whereby words incident at the input path of the said digital information storage device at corresponding instants of successive major cycles are stored in consecutive positions in the store. A long delay-line L, Fig. 2, holds eight words in minor cycles 0-7 and a short delay-line N holds one word. The contents of L circulate via the gates 14 and 16 and the contents of N circulate via the gates 18 and 20. For reading, the delay-line L is operated as a source by applying a pulse S to the gate 22 and for writing is operated as a destination by applying a pulse D to the buffer 42 whereby a copy of any word on the destination highway enters the line L via the gate 24, part of the contents of L being destroyed at the gate 16 to make room for the new information. If a pulse is on D during minor cycle 7 then gate 26 operates to cause entry of a word into N as well as into L. During any other minor cycle a pulse on PD puts on the trigger T which stays on until the end of the major cycle when it is put off by the pulse MC7, operation of the trigger T modifying the normal circulations of L and N by inhibiting the gates 14 and 18 so that the two delay lines have a common circulation via gates 34 and 36. During minor cycle 7 in the absence of a fresh word entry the contexts of N flow into L and also back into N via the gate 18 and the word then flowing out of L is destroyed at the gates 14 and 34. To extract a word from the store, a pulse PS is applied at the corresponding minor cycle and a copy of the word in the last minor cycle of the major cycle goes from N to the source highway via the gate 40. The circulations of N and L are modified by the trigger T in a similar manner to that of the reading operation. The PS and PD pulses may be applied for several consecutive minor cycles to read or write more than one word. The notation explained in Specification 717,114, which is referred to, is used in the drawings.

Filed: 1932-03-30
Abstract: 399,489. Coin-freed article-delivery apparatus. FERGUSON, H., 67, Hoxton Road, Scarborough. March 30, 1932, No. 9111. [Class 27.] Articles stored in piles.-The bottom blade of a pile of wrapped safety-razor blades stored in a magazine 32, Fig. 3, and resting on a delivery drawer 18 is pushed forwards by a plate 33 secured to the top of the drawer, which is drawn out by a handle 22 and then, after disconnection from the handle, suddenly returned by a spring 31 so that the blade drops to a ledge 34. The drawer 18 is normally prevented from being pulled out by a detent 16 engaging a small block 17 and it is connected to the handle 22 by a bolt 29 engaging a catch 24, Fig. 4, which is pivoted at 25 to the handle and held in normal position by a spring 26 and by a pin 27 working in a slot 28. When the drawer is withdrawn, the catch 24 meets a screw 30 fixed to the. framing and is rotated to release the bolt 29 so that the spring 31 can return the drawer. A depending lip on the rear wall of the magazine 32 prevents a blade from being dragged backwards from the pile by the plate 33, and a plate 35 on the front wall prevents more than one blade from being pushed forwards at each actuation. Fraud, preventing.-A prong depending from a hinged plate 36 normally closes the opening between the plate 35 and the drawer and prevents blades from being abstracted without the insertion of a coin. When the drawer is pulled out, it engages a cam 38 on the plate 36 and so raises the obstructing prong. A pawl 42 on the handle 22 coacting with a fixed stop 41 ensures a full stroke of the handle. Coin action, weigh; coin-discharging mechanism.-A coin inserted on a shoot 5 drops on to the forked end of a plate 12 pivoted at 13 and connected bv a chain 15 to the detent 16. The coin tilts the plate 12 and raises the detent to release the drawer. The shoot 5 is secured to a bar 4 rockably mounted on notched plates 2. The drawer in its outward movement meets and rocks on a vertical pivot 21 an angle plate 20 which causes the shoot 5 to rock on the plates 2. A forked extension 11 of the shoot removes the coin from the plate 12 so that it drops to the bottom of the machine casing.

Title: Improvements in or relating to lasting machines
IPC: A43D23/00
Filed: 1929-03-21
Abstract: 325,412. Wade, H., (Nollesche Werke Komm.-Ges.). March 21, 1929. Lasting and pulling-over.-Relates to slitting means of the kind described in Specification 5966/01, and consists in detail improvements. The sliding carriers of the swinging knife-holders are arranged on either side of the wiper in separate housings secured to the frame of the machine behind; the pincers. The knives approach and pierce the leather along a path substantially perpendicular 'to the slitting direction. A carm 18, Fig. 1, on the main shaft operates a pivoted arm 20<a> which, when slitting is required, is clutched by sliding pins 25 to a pivoted arm 20<b>. The pins are withdrawn, when slitting is not required, by a wedge-member 26 operated by a spring plunger 37, which may be locked in operative position by a latch 38. The arm 20<b> operates a slide 24, Fig. 3, to which is pivoted at 4 a member 3 notched at both sides selectively to engage pins 6 on racks 7, Fig. 1, gearing with pinions 8 moving with segments 9 gearing with racks on slides 10, Fig. 8, in fixed housings. To each slide 10 is pivoted a knife-holder 12 urged anti-clockwise by a spring plunger and provided with a tail co-operating with a cam 28. This cam member is pressed upwardly by a spring and formed with an inclined upper surface. The construction is such that as the slide 10 emerges from its housing the knife is swung towards the work by the cam 28 the resultant of the two movements being a movement of the point of the knife substantially perpendicular to the slit to be formed. As the carrier continues to move, the knife executes a drawing cut to the edge of the upper, and is, thereafter, swung out,- ward when the tail of the holder clears the cam 28. On retraction of the slide 10, the cam 28 is pushed downward by the tail of the knife holder. To determine which knife is to operate, the usual knee-lever 31, Fig. 2, carries an inclined guide engaging a roller on a vertical rod 34 secured to a vertical slide 13 slotted at 14<1> to engage a pin on a slide pivoted to the member 3. Movement of the knee-lever to determine the direction of twist of the grippers, in the usual manner, thus determines the engagement of the member 3 with the appropriate pin 6. Specification 14453/97 also is referred to.
