Title: Improvements in and relating to confectionery depositing machines
IPC: A23G3/02
Filed: 1930-11-26
Abstract: 363,106. Moulding confectionery mixtures. BAKER PERKINS, Ltd., TARONI, C. E., and PRESCOTT, W. E., Hythe Road, Willesden, London. Nov. 26,1930, No. 35642. [Class 87 (ii).] A machine for depositing semi-liquid confectionery mixture in a series of measured quantities simultaneously in rows comprises a supply hopper 5, a measuring chamber 3 terminating in a series of dies, a reciprocating gate valve 6 for closing the measuring chamber, a shutter valve 9 at the die openings and a variable-stroke plunger 4 having rectilinear reciprocation in the measuring chamber and adapted to measure the quantity of material deposited. The plunger 4 has a bevelled face 4a which contacts with the wall 2a at the completion of its stroke. The chamber 3 is provided at its lower end with a tray 7 which holds interchangeable die plates 8 having different numbers of apertures 8a. The shutter 9 is reciprocated by a bar 12 which has slots 12a co-operating with angle plates 13 on the shutters. The plates 13 are of varying size so that a uniform stroke of the bar 12 closes the apertures, irrespective of the different displacement required for various sizes of die plates 8. The various operations are controlled by cams mounted on a shaft 14 which is driven through a gear train by the motor 15. The shutter bar 12 is reciprocated by a bifurcated lever 27 which engages a cam 29 on the shaft 14. The plunger 4 is connected by links 31, 32,34 to a slotted quadrant 36 which is oscillated by an eccentric 38 through an arm 39. The stroke of the plunger 4 is adjusted by moving a block 35 in a slot 36a by means of a hand-wheel 44 and rod 40. The sliding gate 6 is actuated by links 49, 48 mounted on a shaft 23 which is oscillated by the cam 29. A conveyer chain 50 is given an intermittent movement, while the die apertures are closed, by a ratchet 53 and a pawl 54 which is oscillated by a cam 57a through levers 56a, 55. A table 57 is pivoted at 59 and is raised and lowered by links 63, 65 which engage a cam on the shaft 14 and can be adjusted by a handscrew 68.

Abstract: 1,147,708. Delivering measured quantities of liquid. G. BAUKNECHT G.m.b.H. 3 Aug., 1967 [20 June, 1967], No. 35754/67. Heading B8N. [Also in Division A4] A cleansing agent dosing device for a dishwashing machine is mounted on the inside of a flap of the machine and comprises a cleansing agent supply chamber 2, a dosing chamber 3, the outlet 5 of which is closable by a magnetic valve 6 and a rotatable dispensing member 7. With the flap of the machine closed, the device lies in a vertical plane so that the inlet 4 to the chamber 3 lies in the upper portion of the device. In this position, operation of the magnetic valve allows cleansing agent from the chamber 3 to enter the machine. To recharge the chamber 3, the flap is pivoted about a horizontal axis so that the device lies in a horizontal plane and liquid from the chamber 2 is able to enter the chamber 3 via the inlet 4. By adjusting the position of the member 7, the quantity of the dose to be dispensed to the machine may be varied.

Title: Apparatus for removing parity bits from binary words
IPC: H04L1/00
Filed: 1973-08-06
Abstract: 1440597 Storage systems BELL & HOWELL CO 6 Aug 1973 [4 Aug 1972 5 Jan 1973] 37151/73 Heading G4C From a first stream of data words including n data bits and p parity bits accompanied by n+p clock pulses a second stream of data is derived from which the parity bits have been removed, the data bits having been expanded to fill the time periods of the removed parity bits i.e. n data bits for n+p clock pulses. As described n= 7 and p=1. In the embodiment of Figs. 1-5 (not shown) incoming data information is fed to 8 bit shift registers (28, 28<SP>1</SP>, 2811). The parity of each register is checked using a checker (75, 75<SP>1</SP>, 75<SP>11</SP>) having even and odd outputs (94, 94<SP>1</SP>, 94<SP>11</SP>: 95, 95, 95<SP>1</SP>, 95<SP>11</SP>). The odd output (95<SP>11</SP>) of the third parity check (75<SP>11</SP>) is connected to an input (92<SP>1</SP>) of the second parity checker (75<SP>1</SP>), the even output (94<SP>1</SP>) of which is connected to an input (92) of the first parity checker (75) so that the odd output (95) of the latter is only high if all three shift registers have words with odd parity. A counter (112) determines after 7, 15 and 23 counts the parity P 3  of the contents of the 3rd register (2811) and resets to zero if it is odd. If at count 23 it is not odd a determination is made after each subsequent count of the parity from the first checker, the counter (112) being reset to zero when it is odd. If a count of 31 is reached without the parity being odd the counter is reset to a count of 24. At each resetting to zero of the counter (112) the word in the 3rd register (28<SP>11</SP>) is transferred in parallel to a shift register (181) from which it is shifted serially, the first input (184) being grounded so that the parity bit is omitted. The read out is effected by clock pulses derived from the original clock pulses which are applied to a phase detector (202) and an amplifier (203) feeding a voltage controlled oscillator (204), the output (247) from which is at 7 times the clock frequency. This output is divided by 8 in a counter (261), the output from which is connected via a lead (286) to the shift register (181) which is consequently clocked at 7/8 times the original clock frequency. Application 37152/73 (Specification 1,435,929) is referred to.

A machine for manufacturing artificial Xmas trees comprises means for holding a trunk forming rod S (or T) and advancing it axially through rotary means 8 (or 105) carrying reels 9 (or 135) from which a flexible trunk covering material 10 (or N), e.g. wire, yarn or tape, is helically wound on the rod S (or T) as it is advanced. In one embodiment (Fig. 1) a motor driven, threaded shaft 2 is rotated to cause movement therealong of an internally threaded member 3 with an arm 3a carrying the trunk rod S in a clamp 4, thereby to advance the rod S axially through a motor driven rotary assembly 8 carrying the reels 9. Branches R have extensions R A  by means of which they are bound to the rod S, the machine including means to intermittently stop the advance of the rod S to give pauses in which the branches R are bound with the speed of the rotary assembly reduced. In another embodiment (Figs. 7, 8) the trunk rod T is held in collets 128 loaded by a spring 129 in a tubular support 123, 123a carried by a plate 120 which is vertically movable in response to rotation of a threaded shaft 118. The rod T is intermittently advanced through an adjustably braked rotor 105 carrying adjustably mounted reels 135 from which tapes N are drawn against the adjustable braking from shoes 137 applied to a disc 134a forming a part of a rotary reel-holding unit 134. The collets 128 are caused to open to release the completed tree when one end 126a of a pivoted lever 126 hits a stop 116a when the plate 120 is raised. The operation is automatically controlled electrically whereby the upward feed of the rod T is stopped at desired locations for securing branches Rx and the rotor 105 speed is reduced at these locations. The machine is automatically switched off on opening the lid 114.
