Title: Web fed rotary variable repeat cutter-creaser system
Inventor: WARD HENRY DAVIS JR
IPC: B31B50/20
Filed: 1968-09-30
Abstract: 1,217,356. Feeding webs. ROTOGRAPHIC MACHINERY CO. 30 Sept., 1968 [10 July, 1968], No. 46237/68. Heading B8R. A web-fed rotary variable repeat cuttercreaser system for performing at least one operation on a web includes oscillatory feeding means which are arranged to form storage loops in the web stock and which advance the web stock periodically to a work member performing a least one operation on the web, control means being coupled to the feeding means to cause a predetermined length of web stock to be advanced to said work member. As shown, a web W is fed to drums 20, 26, carrying cuttercreaser dies 22, 28, by way of feed rolls 82, a guide 84 subject to positive air pressure, swing feed rolls 54, 60 and a guide 88 subject to negative air pressure. The swing rolls 54, 60 are mounted on a pair of oscillating arms 50 which rock back and forth about a shaft 52, the rolls being geared together and driven by a gear 48 associated with a variable speed transmission 32. A main gear 13 on a drive 12 meshes with an idler gear 14 which meshes with an input gear 30 of the variable speed transmission 32 and with a gear 18 secured to the drum 20, the gear 18 meshing with a similar gear 24 secured to the drum 26. A crank 62 connects the drum 20 to the arms 50, the stroke length of the crank being adjustable by means of a slot 72 receiving the crank pin. The movements of the arms 50 are cushioned by a domper 74. The operation of the system, in which a reservoir loop is first formed over the guide 84 and then over the guide 88, is described with reference to Figs. 2 to 7 (not shown). The length of the web stock advanced to the work drums 20, 26 is determined by the rotary speed of the swing rolls 54, 60 and hence by the variable speed transmission 32 which is adjusted, e.g. by means of a change gear 34B to provide the desired result, the length of the crank 62 being correspondingly adjusted so that the linear motion of the arms 50, when added to the rotary feeding motion of the web, results in the web being fed to the drums 20, 26, at the instant of the beginning of the cut, at the surface speed of the cutting dies 22, 28. A conventional register control sensor 86, e.g. of the photo-electric, magnetic or punched-hole sensing type, and an angular position monitor 92 associated with the drum 20 produce signals to control a compensator 94 for the variable speed transmission 32, whereby any error in the desired position of the cutting drums 20 and 26 relative to printed matter on the web stock W is corrected. A further conventional sensor 100 controls drive rolls 82 to ensure that a free loop always exists in front of the feed rolls 54, 60.

Title: Production of fermentable syrups
Inventor: IMRIE FRAZER KEITH ELLIOTT
IPC: C12P19/14
Filed: 1967-10-14
Abstract: 1,203,623. Syrups. A.B.M.G. (SYRUPS) Ltd. 10 Jan., 1969 [14 Oct., 1967], No. 46942/67. Heading A2B. [Also in Division C6]  A process for the production of a syrup, which is yeast fermentable when diluted, from a starch-and protein-containing plant material comprises the steps of forming an aqueous mash of the material, solubilising starch in the mash by means of a mineral acid (hydrochloric or phosphoric acids) and/or a commercial enzyme (a bacterial α-amylase), neutralising the acid if acid is used in the solubilisation step, adding to the mash an enzyme capable of breaking down solubilised starch to fermentable sugars, maintaining the mash containing this enzyme at a controlled pH and temperature for a required period of time (pH in the range 4-7, temperature between 45‹ and 80‹C.), and concentrating the resultant liquid to a syrup, an enzyme capable of protein breakdown being added at a required stage in the process, e.g. with the commercial enzyme and/or with the enzyme for breaking down the solubilised starch. Plant materials: Wheat, maize, barley, rice, soya, roots, fungal material and cerial by-products. Solubilisation of the starch by mineral acid is carried out at a temperature between 90‹ and 155‹C. and a pH in the range 0.5-2 for not more than 5 hours. The corresponding conditions when commercial enzyme is used are 55‹- 100‹C. and pH 5-8 for not more than 8 hours. When α- or #-amylase (or malt extract containing them) is used for breaking down the starch, the resultant fermentable sugar in the syrup is maltose, but if amyloglucosidase is used the predominant resultant sugar will be glucose. The syrups can be used as the raw material for the production of ethyl alcohol by fermentation or as a partial replacement for malt in the mash tun. Pure glucose syrup may be added to vary the soluble protein concentration. The syrups may be dried and ground for use as food.

Filed: 1973-10-12
Abstract: 1439279 Digital storage systems RCA CORPORATION 12 Oct 1973 [20 Oct 1972] 47689/73 Heading G4C [Also in Division H3] Each stage of a multi-bit store comprises first and second logical product gates feeding a logical sum gate whose output, the output of the cell, is fed back to the input of the second gate. The bit to be stored is applied to the first gate. The first gate is enabled, and the second gate inhibited, by outputs from a control circuit in response to a timing pulse. The cells and the control circuit are formed as an integrated circuit. The cells are each as shown as stage 2<SP>j</SP>, Fig. 3, and consist of AND gates 10, 12 and OR gate 16, providing an output Q. Each stage is connected to a common control circuit. Gate 46 and gate pairs 40, 44; 42, 44; 10, 16; and 12, 16, all provide about the same delay, e.g. 8 nanoseconds. Thus 8 ns. after timing pulse TP becomes high gate 10 is enabled via gates 30, 44 and is maintained enabled until 16 ns. after the end of TP via gates 46, 42, 44. Output Q takes the state of input bit D, here assumed high, 8 ns. after the gate 10 is enabled. The output of gate 46 becomes high 8 ns. after the end of TP, and since at this time Q is still high gates 12, 16 lock up to maintain Q high until 16 ns. after the start of the next pulse TP. In an alternative arrangement, Fig. 1, the control circuit comprises gates 18, 20, 22, each having 8 ns. delay. Gates 20, 22 are enabled by signals A, B. The cells in this arrangement include an additional gate so that an input digit D A  or D B -or possibly both simultaneously-can be applied to OR gate 16 dependent upon the states of signals A and B. The operation is generally similar to that of Fig. 3.
