Title: Gripper control device for sheet handling machines
Inventor: RUDOLPH OTFRIED
IPC: B41F21/10
Filed: 1967-04-11
Abstract: 1,148,017. Gripper mechanism. DRUCKMASCHINENWERK PLANETA VEB. 11 April, 1967, No. 16445/67. Heading B6C. A gripper control device, whereby the grippers carried on a rocker shaft are opened and closed by a cam disc through a lever carrying a cam follower, a coupling rod, and a further lever connected to the rocker shaft, has the pivot connecting the coupling rod and the cam follower lever lying in alignment with the centre of the rocker shaft when the grippers are closed. The device is especially applicable to multicolour rotary sheet printing machines, the grippers being located on rocker shafts located eccentrically of each transfer cylinder axis. Figs. 1 and 3 illustrate a transfer cylinder 1 and a rocker shaft 2 mounted in the cylinder; fixed to rocker shaft 2 are a number of rocker arms 4 carrying the gripper shaft 3 and a number of holders 5 carrying a gripper facing-piece rail 6; the gripper shaft 3 carries the grippers 7. When the rocker shaft 2 is rotated by a drive (not shown), the gripper shaft 3 with associated grippers 7 and the holders 5 with rail 6 swing inwards towards the middle of the cylinder to effect sheet transfer. A cam roller 15 rides on cam path 18 of a disc 17 attached to the machine wall; a lever 13 mounted on central pivot 14 is articulated to the cam roller 15 and at the other end to a coupling rod 11 by means of bolt 12. The coupling rod 11 is, in turn, articulated at bolt 10 to a further lever 9 fixed to gripper shaft 3. Thus movement of lever 13 is transmitted through coupling rod 11 and lever 9 to the grippers shaft 3, and the cam disc 17 therefore controls movement of grippers 7. When the centre of bolt 12 and of the rocker shaft lie in one alignment with the grippers 7 closed (Fig. 4, not shown), then the swinging movement of the whole gripper system 8 about the rocker shaft causes no relative movement between the grippers 7 and rail 6, i.e. they remain closed. Only when the centres are moved out of alignment (Fig. 5, not shown) do the grippers open; thus the cam disc 17 and path 18 is arranged to open the grippers as required. Inaccuracies in the alignment will cause the grippers to open at the wrong moment; in order to prevent this, the alignment is checked with an adjusting bolt (21) which is introduced simultaneously into the cam follower lever bore (22) and the rocker shaft bore (23) (Figs. 6, 7, not shown). The grippers 7 can be similarly checked by introducing the bolt (21) into the coupling rod bore (24) and the rocker shaft bore (23) (Figs. 8, 9, not shown).

Title: Improvements in or relating to the production of fabrics treated with waterproof compositions of or containing rubber
IPC: D06N3/00
Filed: 1935-06-07
Abstract: Fabrics &c. coated with rubber &c. are produced by forming one or more nips by positioning two or more moving surfaces, applying aqueous emulsions or dispersions of rubber &c. to one or more of the moving surfaces so as to form a layer thereon, effecting coagulation of the layer or layers before they enter the nip in such a way that coagulation proceeds outwardly from the moving surface, feeding fabric &c. into the one or more nips, and withdrawing the coated fabric through the nip or nips.  "Striking through" of the latex is thus prevented.  Waterproofed fabrics, weftless cord fabrics, rubber-backed carpets, and substitutes for cork, leather, and linoleum may be so produced, and felt or carded materials, e.g. cotton wool, silk or rayon may be coated.  The nip or nips may be formed by positioning two or more rotating rollers, or two endless belts, or one endless belt and one roller, or by positioning two or more moving lengths of fabric, or by introducing one or more moving lengths of fabric through two rotating rollers.  The layer or layers of dispersion may be coagulated by providing the moving surfaces with coagulant, or where heat-sensitive dispersions are used by heating the surfaces.  Heat sensitizing agents include sodium or potassium silicofluoride, ammonium persulphate or reagents which react on heating to produce coagulants, e.g. zinc oxide and ammonium sulphate. When a length of fabric is employed as a moving surface, adhesion of the coagulated rubber is prevented by the treatment with coagulant, or when coagulation is by heating, a fabric coated, e.g. with shellac or a cellulose derivative lacquer is used.  Rollers, if employed, may be covered with hard rubber. Natural or artificial dispersions of rubber, guttapercha, balata, vulcanized rubber, synthetic rubber, waste, or reclaim, alone or mixed, may be used.  The concentrated dispersions described in Specifications 219,635 and 290,313, [both in Class 70], may be used.  Frothed dispersions may be used, e.g. those described in Specifications 332,525 and 332,526, [both in Class 70], to produce fabric coated with cellular rubber.  Specifications 416,077, 448,132; and 451,622, [Group VIII], also are referred to.

Title: Improvements in or connected with radio-navigational apparatus and the like
IPC: G01S1/02
Filed: 1919-07-04
Abstract: 149,827. Murray, J. Erskine-, Robinson, J., and Crowther, H. L. July 4, 1919. Bearings, determining wirelessly; directive wireless signalling. -Relates to receiving- apparatus for a direction-finding system in which a directive transmitter emits waves having a distinctive wave-length or frequeney for each direction of transmission, as described in Specificalion 149,826. A receiving-station can determine its bearing with respect to the transmitting-station by determining the frequency at which the energy of the received wave is a maximum or a minimum. In Fig. 1, the curve b a c a b represents the energy received by a receiving- aerial when the transmitting-system completes a cycle of 180 degrees. If the receiving- system is tuned to the wave, the energy of which is a minimum at that station, that is if the peak of the resonance curve d coincides with the minimum c of the direction-finding curve, the intensity of the signals received is represented by the symmetrical curve e. If, however, the receiving- system is tuned to a different frequency, say that represenced by the dotted resonance curve d<x>. the signal curve e<x> is unsymmetrical on the two sides of the minimum and signals of unequal intensity are produced in the telephones. According to the invention, the direction of the transmitter is obtained by tuning the receiving-system until notes or swells of sound of equal intensity or pitch (corresponding to the curve e) are received. When using heterodyne reception, the received waves are combined with waves from a valve generator g, Fig. 2, the frequency of which can be readily determined by the circuit f, and led through a rectifying-valve h to a low-frequency valve n which does not oscillate but has retroactive connexions to reduce the damping. As the wave-length of the transmitting-station approaches and recedes from that to which the circuit f is tuned, the heterodyne swells are modified, each swell having a preponderating note. The valve n &c. may be such that only the note to which the circuit j is tuned can be heard, and the circuit f is then adjusted until the two notes, on each side of the minimum, are of equal intensity. When the range of transmitted wave-lengths is large, the arrangement shown in Fig. 3, is used, two heterodyne circuits p, q being coupled to the same aerial s and to the same telephone t. The tuning of the circuits p, q is varied together so that there is a constant difference of wave-length or frequency. Two notes of equal intensity are produced in the telephones when the received wave has a frequency midway between that of the two circuits p, q.

Title: Process for preparing insulin
IPC: C07K14/625
Filed: 1958-05-28
Abstract: Pancreas glands are extracted with an acidified alcohol and the acidified alcoholic extract heated to inactivate proteolytic enzymes contained therein before recovering the insulin.  The alcohol used for the extraction may be an aliphatic alcohol containing 1-4 carbon atoms acidified by hydrochloric, acetic, citric or oxalic acid.  The frozen minced glands are extracted at room temperature for 4-5 hours. Preferably the alcoholic extract at pH 2.0-4.5 is raised to 70-75 DEG C. during not more than 30 minutes and kept at that temperature for 5-10 minutes before cooling or directly cooled to room temperature during not more than 30 minutes.  Alternatively the initial heating may be faster, e.g. 10-15 seconds, and the temperature kept at 70-75 DEG  C. for not more than 10 minutes.  Specified pancreas are ox, calf, cattle, hog and horse.  The alcoholic extract may be purified before or after heating by adding ammonia to produce a pH of about 8.5 and subsequently the extract is brought to a pH of 2.8-3.4 by the addition of acid or the action of a sulphonated highly cross-linked cation exchanger such as "Dowex" (Registered Trade Mark) 50.  The heated extract may be treated with a carboxylic cation exchanger, such as "Amberlite" (Registered Trade Mark), oxycellulose, pectic acid or alginic acid, the adsorbate eluted with a mineral acid and the insulin precipitated from the eluate, or submitted to distillation at low temperature and reduced pressure, whereafter the insulin, after removal of fatty material, is precipitated from the aqueous residue obtained.
